35 | \C{intro} Introduction |
36 | |
37 | I wrote this collection because I thought there should be more small |
38 | desktop toys available: little games you can pop up in a window and |
39 | play for two or three minutes while you take a break from whatever |
8a771ea7 |
40 | else you were doing. And I was also annoyed that every time I found |
41 | a good game on (say) \i{Unix}, it wasn't available the next time I |
42 | was sitting at a \i{Windows} machine, or vice versa; so I arranged |
43 | that everything in my personal puzzle collection will happily run on |
bb219ea1 |
44 | both, and have more recently done a port to \i{Mac OS X} as well. When I |
8a771ea7 |
45 | find (or perhaps invent) further puzzle games that I like, they'll |
46 | be added to this collection and will immediately be available on |
47 | both platforms. And if anyone feels like writing any other front |
f1010613 |
48 | ends \dash PocketPC, Mac OS pre-10, or whatever it might be \dash |
49 | then all the games in this framework will immediately become |
50 | available on another platform as well. |

52 | The actual games in this collection were mostly not my invention; they |
53 | are re-implementations of existing game concepts within my portable |
54 | puzzle framework. I do not claim credit, in general, for inventing the |
55 | rules of any of these puzzles. (I don't even claim authorship of all |
56 | the code; some of the puzzles have been submitted by other authors.) |

57 | |
58 | This collection is distributed under the \i{MIT licence} (see |
59 | \k{licence}). This means that you can do pretty much anything you like |
60 | with the game binaries or the code, except pretending you wrote them |
61 | yourself, or suing me if anything goes wrong. |

72 | \ii{Patches} are welcome. Especially if they provide a new front end |
73 | (to make all these games run on another platform), or a new game. |
74 | |
75 | |
76 | \C{common} \ii{Common features} |
77 | |
78 | This chapter describes features that are common to all the games. |
79 | |
80 | \H{common-actions} \I{controls}Common actions |
81 | |
82 | These actions are all available from the \I{Game menu}\q{Game} menu |
83 | and via \I{keys}keyboard shortcuts, in addition to any game-specific |
84 | actions. |
85 | |
bb219ea1 |
86 | (On \i{Mac OS X}, to conform with local user interface standards, these |
3101ae26 |
87 | actions are situated on the \I{File menu}\q{File} and \I{Edit |
bacaa96e |
88 | menu}\q{Edit} menus instead.) |
89 | |
e91825f8 |
90 | \dt \ii\e{New game} (\q{N}, Ctrl+\q{N}) |
91 | |
92 | \dd Starts a new game, with a random initial state. |
93 | |
2b06373b |
94 | \dt \ii\e{Restart game} |
e91825f8 |
95 | |
2b06373b |
96 | \dd Resets the current game to its initial state. (This can be undone.) |
e91825f8 |
97 | |
668be019 |
98 | \dt \ii\e{Load} |
99 | |
100 | \dd Loads a saved game from a file on disk. |
101 | |
102 | \dt \ii\e{Save} |
103 | |
104 | \dd Saves the current state of your game to a file on disk. |
105 | |
106 | \lcont{ |
107 | |
ff359b8a |
108 | The Load and Save operations preserve your entire game |
668be019 |
109 | history (so you can save, reload, and still Undo and Redo things you |
110 | had done before saving). |
111 | |
112 | } |
113 | |
3c9388ef |
114 | \dt \I{printing, on Windows}\e{Print} |
e28d0584 |
115 | |
116 | \dd Where supported (currently only on Windows), brings up a dialog |
117 | allowing you to print an arbitrary number of puzzles randomly |
118 | generated from the current parameters, optionally including the |
3c9388ef |
119 | current puzzle. (Only for puzzles which make sense to print, of |
120 | course - it's hard to think of a sensible printable representation |
121 | of Fifteen!) |
e28d0584 |
122 | |
e91825f8 |
123 | \dt \ii\e{Undo} (\q{U}, Ctrl+\q{Z}, Ctrl+\q{_}) |
124 | |
125 | \dd Undoes a single move. (You can undo moves back to the start of the |
2b06373b |
126 | session.) |
e91825f8 |
127 | |
2b06373b |
128 | \dt \ii\e{Redo} (\q{R}, Ctrl+\q{R}) |
e91825f8 |
129 | |
2b06373b |
130 | \dd Redoes a previously undone move. |
e91825f8 |
131 | |
bacaa96e |
132 | \dt \ii\e{Copy} |
133 | |
134 | \dd Copies the current state of your game to the clipboard in text |
135 | format, so that you can paste it into (say) an e-mail client or a |
136 | web message board if you're discussing the game with someone else. |
137 | (Not all games support this feature.) |
138 | |
2ac6d24e |
139 | \dt \ii\e{Solve} |
140 | |
141 | \dd Transforms the puzzle instantly into its solved state. For some |
142 | games (Cube) this feature is not supported at all because it is of |
143 | no particular use. For other games (such as Pattern), the solved |
144 | state can be used to give you information, if you can't see how a |
145 | solution can exist at all or you want to know where you made a |
146 | mistake. For still other games (such as Sixteen), automatic solution |
147 | tells you nothing about how to \e{get} to the solution, but it does |
148 | provide a useful way to get there quickly so that you can experiment |
149 | with set-piece moves and transformations. |
150 | |
151 | \lcont{ |
152 | |
153 | Some games (such as Solo) are capable of solving a game ID you have |
154 | typed in from elsewhere. Other games (such as Rectangles) cannot |
155 | solve a game ID they didn't invent themself, but when they did |
156 | invent the game ID they know what the solution is already. Still |
157 | other games (Pattern) can solve \e{some} external game IDs, but only |
158 | if they aren't too difficult. |
159 | |
e8124727 |
160 | The \q{Solve} command adds the solved state to the end of the undo |
161 | chain for the puzzle. In other words, if you want to go back to |
162 | solving it yourself after seeing the answer, you can just press Undo. |
163 | |
2ac6d24e |
164 | } |
165 | |
e91825f8 |
166 | \dt \I{exit}\ii\e{Quit} (\q{Q}, Ctrl+\q{Q}) |
167 | |
168 | \dd Closes the application entirely. |
169 | |
1185e3c5 |
170 | \H{common-id} Specifying games with the \ii{game ID} |
171 | |
172 | There are two ways to save a game specification out of a puzzle and |
173 | recreate it later, or recreate it in somebody else's copy of the |
174 | same puzzle. |
175 | |
176 | The \q{\i{Specific}} and \q{\i{Random Seed}} options from the |
bb219ea1 |
177 | \I{Game menu}\q{Game} menu (or the \q{File} menu, on \i{Mac OS X}) each |
1185e3c5 |
178 | show a piece of text (a \q{game ID}) which is sufficient to |
179 | reconstruct precisely the same game at a later date. |
180 | |
181 | You can enter either of these pieces of text back into the program |
182 | (via the same \q{Specific} or \q{Random Seed} menu options) at a |
183 | later point, and it will recreate the same game. You can also use |
184 | either one as a \i{command line} argument (on Windows or Unix); see |
185 | \k{common-cmdline} for more detail. |
186 | |
187 | The difference between the two forms is that a descriptive game ID |
188 | is a literal \e{description} of the \i{initial state} of the game, |
189 | whereas a random seed is just a piece of arbitrary text which was |
190 | provided as input to the random number generator used to create the |
191 | puzzle. This means that: |
192 | |
193 | \b Descriptive game IDs tend to be longer in many puzzles (although |
194 | some, such as Cube (\k{cube}), only need very short descriptions). |
195 | So a random seed is often a \e{quicker} way to note down the puzzle |
196 | you're currently playing, or to tell it to somebody else so they can |
197 | play the same one as you. |
198 | |
199 | \b Any text at all is a valid random seed. The automatically |
200 | generated ones are fifteen-digit numbers, but anything will do; you |
201 | can type in your full name, or a word you just made up, and a valid |
202 | puzzle will be generated from it. This provides a way for two or |
203 | more people to race to complete the same puzzle: you think of a |
204 | random seed, then everybody types it in at the same time, and nobody |
205 | has an advantage due to having seen the generated puzzle before |
206 | anybody else. |
207 | |
208 | \b It is often possible to convert puzzles from other sources (such |
209 | as \q{nonograms} or \q{sudoku} from newspapers) into descriptive |
210 | game IDs suitable for use with these programs. |
211 | |
212 | \b Random seeds are not guaranteed to produce the same result if you |
213 | use them with a different \i\e{version} of the puzzle program. This |
214 | is because the generation algorithm might have been improved or |
215 | modified in later versions of the code, and will therefore produce a |
216 | different result when given the same sequence of random numbers. Use |
217 | a descriptive game ID if you aren't sure that it will be used on the |
218 | same version of the program as yours. |
219 | |
220 | \lcont{(Use the \q{About} menu option to find out the version number |
221 | of the program. Programs with the same version number running on |
222 | different platforms should still be random-seed compatible.)} |
223 | |
224 | \I{ID format}A descriptive game ID starts with a piece of text which |
225 | encodes the \i\e{parameters} of the current game (such as grid |
226 | size). Then there is a colon, and after that is the description of |
227 | the game's initial state. A random seed starts with a similar string |
228 | of parameters, but then it contains a hash sign followed by |
229 | arbitrary data. |
230 | |
231 | If you enter a descriptive game ID, the program will not be able to |
232 | show you the random seed which generated it, since it wasn't |
233 | generated \e{from} a random seed. If you \e{enter} a random seed, |
234 | however, the program will be able to show you the descriptive game |
235 | ID derived from that random seed. |
236 | |
237 | Note that the game parameter strings are not always identical |
238 | between the two forms. For some games, there will be parameter data |
239 | provided with the random seed which is not included in the |
240 | descriptive game ID. This is because that parameter information is |
241 | only relevant when \e{generating} puzzle grids, and is not important |
242 | when playing them. Thus, for example, the difficulty level in Solo |
243 | (\k{solo}) is not mentioned in the descriptive game ID. |
244 | |
245 | These additional parameters are also not set permanently if you type |
246 | in a game ID. For example, suppose you have Solo set to \q{Advanced} |
247 | difficulty level, and then a friend wants your help with a |
248 | \q{Trivial} puzzle; so the friend reads out a random seed specifying |
249 | \q{Trivial} difficulty, and you type it in. The program will |
250 | generate you the same \q{Trivial} grid which your friend was having |
251 | trouble with, but once you have finished playing it, when you ask |
252 | for a new game it will automatically go back to the \q{Advanced} |
253 | difficulty which it was previously set on. |
e91825f8 |
254 | |
255 | \H{common-type} The \q{Type} menu |
256 | |
257 | The \I{Type menu}\q{Type} menu, if present, may contain a list of |
258 | \i{preset} game settings. Selecting one of these will start a new |
259 | random game with the parameters specified. |
260 | |
1185e3c5 |
261 | The \q{Type} menu may also contain a \q{\i{Custom}} option which |
262 | allows you to fine-tune game \i{parameters}. The parameters |
263 | available are specific to each game and are described in the |
264 | following sections. |
e91825f8 |
265 | |
266 | \H{common-cmdline} Specifying game parameters on the \i{command line} |
267 | |
bb219ea1 |
268 | (This section does not apply to the \i{Mac OS X} version.) |
8a771ea7 |
269 | |
e91825f8 |
270 | The games in this collection deliberately do not ever save |
271 | information on to the computer they run on: they have no high score |
272 | tables and no saved preferences. (This is because I expect at least |
273 | some people to play them at work, and those people will probably |
274 | appreciate leaving as little evidence as possible!) |
275 | |
bb219ea1 |
276 | However, if you do want to arrange for one of these games to |
277 | \I{default parameters, specifying}default to a particular set of |
278 | parameters, you can specify them on the command line. |
e91825f8 |
279 | |
280 | The easiest way to do this is to set up the parameters you want |
281 | using the \q{Type} menu (see \k{common-type}), and then to select |
1185e3c5 |
282 | \q{Random Seed} from the \q{Game} or \q{File} menu (see |
283 | \k{common-id}). The text in the \q{Game ID} box will be composed of |
284 | two parts, separated by a hash. The first of these parts represents |
285 | the game parameters (the size of the playing area, for example, and |
286 | anything else you set using the \q{Type} menu). |
e91825f8 |
287 | |
288 | If you run the game with just that parameter text on the command |
289 | line, it will start up with the settings you specified. |
290 | |
291 | For example: if you run Cube (see \k{cube}), select \q{Octahedron} |
292 | from the \q{Type} menu, and then go to the game ID selection, you |
1185e3c5 |
293 | will see a string of the form \cq{o2x2#338686542711620}. Take only |
294 | the part before the hash (\cq{o2x2}), and start Cube with that text |
295 | on the command line: \cq{cube o2x2}. |
e91825f8 |
296 | |
297 | If you copy the \e{entire} game ID on to the command line, the game |
298 | will start up in the specific game that was described. This is |
299 | occasionally a more convenient way to start a particular game ID |
300 | than by pasting it into the game ID selection box. |
301 | |
1185e3c5 |
302 | (You could also retrieve the encoded game parameters using the |
303 | \q{Specific} menu option instead of \q{Random Seed}, but if you do |
304 | then some options, such as the difficulty level in Solo, will be |
305 | missing. See \k{common-id} for more details on this.) |
306 | |
bb219ea1 |
307 | \H{common-unix-cmdline} \i{Unix} \i{command-line} options |
3c9388ef |
308 | |
309 | (This section only applies to the Unix port.) |
310 | |
ff359b8a |
311 | In addition to being able to specify game parameters on the command |
312 | line (see \k{common-cmdline}), there are various other options: |
313 | |
314 | \dt \cw{--game} |
315 | |
316 | \dt \cw{--load} |
317 | |
318 | \dd These options respectively determine whether the command-line |
319 | argument is treated as specifying game parameters or a \i{save} file |
320 | to \i{load}. Only one should be specified. If neither of these options |
321 | is specified, a guess is made based on the format of the argument. |
3c9388ef |
322 | |
323 | \dt \cw{--generate }\e{n} |
324 | |
325 | \dd If this option is specified, instead of a puzzle being displayed, |
bb219ea1 |
326 | a number of descriptive game IDs will be \I{generating game IDs}invented |
327 | and printed on standard output. This is useful for gaining access to |
328 | the game generation algorithms without necessarily using the frontend. |
3c9388ef |
329 | |
330 | \lcont{ |
331 | |
332 | If game parameters are specified on the command-line, they will be |
333 | used to generate the game IDs; otherwise a default set of parameters |
334 | will be used. |
335 | |
336 | The most common use of this option is in conjunction with \c{--print}, |
337 | in which case its behaviour is slightly different; see below. |
338 | |
339 | } |
340 | |
341 | \dt \I{printing, on Unix}\cw{--print }\e{w}\cw{x}\e{h} |
342 | |
343 | \dd If this option is specified, instead of a puzzle being displayed, |
344 | a printed representation of one or more unsolved puzzles is sent to |
345 | standard output, in \i{PostScript} format. |
346 | |
347 | \lcont{ |
348 | |
349 | On each page of puzzles, there will be \e{w} across and \e{h} down. If |
350 | there are more puzzles than \e{w}\by\e{h}, more than one page will be |
351 | printed. |
352 | |
353 | If \c{--generate} has also been specified, the invented game IDs will |
354 | be used to generate the printed output. Otherwise, a list of game IDs |
355 | is expected on standard input (which can be descriptive or random |
356 | seeds; see \k{common-id}), in the same format produced by |
357 | \c{--generate}. |
358 | |
359 | For example: |
360 | |
361 | \c net --generate 12 --print 2x3 7x7w | lpr |
362 | |
363 | will generate two pages of printed Net puzzles (each of which will |
364 | have a 7\by\.7 wrapping grid), and pipe the output to the \c{lpr} |
365 | command, which on many systems will send them to an actual printer. |
366 | |
367 | There are various other options which affect printing; see below. |
368 | |
369 | } |
370 | |
371 | \dt \cw{--version} |
372 | |
373 | \dd Prints version information about the game, and then quits. |
374 | |
375 | The following options are only meaningful if \c{--print} is also |
376 | specified: |
377 | |
378 | \dt \cw{--with-solutions} |
379 | |
380 | \dd The set of pages filled with unsolved puzzles will be followed by |
381 | the solutions to those puzzles. |
382 | |
383 | \dt \cw{--scale }\e{n} |
384 | |
385 | \dd Adjusts how big each puzzle is when printed. Larger numbers make |
386 | puzzles bigger; the default is 1.0. |
387 | |
388 | \dt \cw{--colour} |
389 | |
390 | \dd Puzzles will be printed in colour, rather than in black and white |
391 | (if supported by the puzzle). |
392 | |

395 | |
396 | \cfg{winhelp-topic}{games.net} |
397 | |
398 | (\e{Note:} the \i{Windows} version of this game is called |
399 | \i\cw{NETGAME.EXE} to avoid clashing with Windows's own \cw{NET.EXE}.) |
400 | |
401 | I originally saw this in the form of a Flash game called \i{FreeNet} |
6e8e5c51 |
402 | \k{FreeNet}, written by Pavils Jurjans; there are several other |
403 | implementations under the name \i{NetWalk}. The computer prepares a |
e91825f8 |
404 | network by connecting up the centres of squares in a grid, and then |
405 | shuffles the network by rotating every tile randomly. Your job is to |
406 | rotate it all back into place. The successful solution will be an |
6e8e5c51 |
407 | entirely connected network, with no closed loops. \#{The latter |
408 | clause means that there are no closed paths within the network. |
409 | Could this be clearer? "No closed paths"?} As a visual aid, |
e91825f8 |
410 | all tiles which are connected to the one in the middle are |
411 | highlighted. |

486 | (see \k{common-id}), change the \e{Barrier probability} parameter, |
487 | and then re-enter the same random seed, you should see exactly the |
488 | same starting grid, with the only change being the number of |
489 | barriers. So if you're stuck on a particular grid and need a hint, |
490 | you could start up another instance of Net, set up the same |

508 | \cfg{winhelp-topic}{games.cube} |
509 | |
510 | This is another one I originally saw as a web game. This one was a |
511 | Java game \k{cube-java-game}, by Paul Scott. You have a grid of 16 |
512 | squares, six of which are blue; on one square rests a cube. Your move |
513 | is to use the arrow keys to roll the cube through 90 degrees so that |
514 | it moves to an adjacent square. If you roll the cube on to a blue |
515 | square, the blue square is picked up on one face of the cube; if you |
516 | roll a blue face of the cube on to a non-blue square, the blueness is |
517 | put down again. (In general, whenever you roll the cube, the two faces |
518 | that come into contact swap colours.) Your job is to get all six blue |
519 | squares on to the six faces of the cube at the same time. Count your |
520 | moves and try to do it in as few as possible. |
521 | |
522 | Unlike the original Java game, my version has an additional feature: |
523 | once you've mastered the game with a cube rolling on a square grid, |
524 | you can change to a triangular grid and roll any of a tetrahedron, an |
525 | octahedron or an icosahedron. |

542 | On the triangular grids, the mapping of arrow keys to directions is |
543 | more approximate. Vertical movement is disallowed where it doesn't |

571 | with sliding tiles. You have a 4\by\.4 square grid; 15 squares |
572 | contain numbered tiles, and the sixteenth is empty. Your move is to |
573 | choose a tile next to the empty space, and slide it into the space. |
574 | The aim is to end up with the tiles in numerical order, with the |
575 | space in the bottom right (so that the top row reads 1,2,3,4 and the |
576 | bottom row reads 13,14,15,\e{space}). |

606 | Another sliding tile puzzle, visually similar to Fifteen (see |
607 | \k{fifteen}) but with a different type of move. This time, there is no |
608 | hole: all 16 squares on the grid contain numbered squares. Your move |
609 | is to shift an entire row left or right, or shift an entire column up |
610 | or down; every time you do that, the tile you shift off the grid |
611 | re-appears at the other end of the same row, in the space you just |
612 | vacated. To win, arrange the tiles into numerical order (1,2,3,4 on |
613 | the top row, 13,14,15,16 on the bottom). When you've done that, try |
614 | playing on different sizes of grid. |
615 | |
616 | I \e{might} have invented this game myself, though only by accident if |
617 | so (and I'm sure other people have independently invented it). I |
618 | thought I was imitating a screensaver I'd seen, but I have a feeling |
619 | that the screensaver might actually have been a Fifteen-type puzzle |
620 | rather than this slightly different kind. So this might be the one |
621 | thing in my puzzle collection which represents creativity on my part |

641 | that any arrangement is about as probable as any other. You can |
642 | override this by requesting a precise number of shuffling moves to |
643 | be performed. Typically your aim is then to determine the precise |
644 | set of shuffling moves and invert them exactly, so that you answer |
645 | (say) a four-move shuffle with a four-move solution. Note that the |

653 | |
654 | Twiddle is a tile-rearrangement puzzle, visually similar to Sixteen |
655 | (see \k{sixteen}): you are given a grid of square tiles, each |
656 | containing a number, and your aim is to arrange the numbers into |
657 | ascending order. |
658 | |
659 | In basic Twiddle, your move is to rotate a square group of four |
a3631c72 |
660 | tiles about their common centre. (Orientation is not significant in |
661 | the basic puzzle, although you can select it.) On more advanced |
662 | settings, you can rotate a larger square group of tiles. |
9038fd11 |
663 | |
664 | I first saw this type of puzzle in the GameCube game \q{Metroid |
665 | Prime 2}. In the Main Gyro Chamber in that game, there is a puzzle |
666 | you solve to unlock a door, which is a special case of Twiddle. I |

671 | To play Twiddle, click the mouse in the centre of the square group |
672 | you wish to rotate. In the basic mode, you rotate a 2\by\.2 square, |
673 | which means you have to click at a corner point where four tiles |
674 | meet. |
675 | |
676 | In more advanced modes you might be rotating 3\by\.3 or even more at |
677 | a time; if the size of the square is odd then you simply click in |
678 | the centre tile of the square you want to rotate. |
679 | |
680 | Clicking with the left mouse button rotates the group anticlockwise. |
681 | Clicking with the right button rotates it clockwise. |

694 | \b You can ask for every square in the grid to be distinguishable |
695 | (the default), or you can ask for a simplified puzzle in which there |
696 | are groups of identical numbers. In the simplified puzzle your aim |
697 | is just to arrange all the 1s into the first row, all the 2s into |
698 | the second row, and so on. |

770 | The default expansion factor of zero means that Rectangles will |
771 | simply generate a grid of the size you ask for, and do nothing |
772 | further. If you set an expansion factor of (say) 0.5, it means that |
773 | each dimension of the grid will be expanded to half again as big |
774 | after generation. In other words, the initial grid will be 2/3 the |

863 | |
864 | You have a square grid, which is divided into square or rectangular |
865 | blocks. Each square must be filled in with a digit from 1 to the |
866 | size of the grid, in such a way that |
867 | |
868 | \b every row contains only one occurrence of each digit |
869 | |
870 | \b every column contains only one occurrence of each digit |
871 | |
872 | \b every block contains only one occurrence of each digit. |
873 | |
874 | You are given some of the numbers as clues; your aim is to place the |
875 | rest of the numbers correctly. |
876 | |
877 | The default puzzle size is 3\by\.3 (a 9\by\.9 actual grid, divided |
878 | into nine 3\by\.3 blocks). You can also select sizes with |
879 | rectangular blocks instead of square ones, such as 2\by\.3 (a |
880 | 6\by\.6 grid divided into six 3\by\.2 blocks). |
881 | |
882 | If you select a puzzle size which requires more than 9 digits, the |
883 | additional digits will be letters of the alphabet. For example, if |
884 | you select 3\by\.4 then the digits which go in your grid will be 1 |
885 | to 9, plus \cq{a}, \cq{b} and \cq{c}. |

887 | I first saw this puzzle in \i{Nikoli} \k{nikoli-solo}, although it's |
888 | also been popularised by various newspapers under the name |
889 | \q{Sudoku} or \q{Su Doku}. Howard Garns is considered the inventor |
890 | of the modern form of the puzzle, and it was first published in |
891 | \e{Dell Pencil Puzzles and Word Games}. A more elaborate treatment |
892 | of the history of the puzzle can be found on Wikipedia |
893 | \k{wikipedia-solo}. |

901 | To play Solo, simply click the mouse in any empty square and then |
902 | type a digit or letter on the keyboard to fill that square. If you |
903 | make a mistake, click the mouse in the incorrect square and press |
904 | Space to clear it again (or use the Undo feature). |
905 | |
c8266e03 |
906 | If you \e{right}-click in a square and then type a number, that |
907 | number will be entered in the square as a \q{pencil mark}. You can |
908 | have pencil marks for multiple numbers in the same square. |
909 | |
910 | The game pays no attention to pencil marks, so exactly what you use |
911 | them for is up to you: you can use them as reminders that a |
912 | particular square needs to be re-examined once you know more about a |
913 | particular number, or you can use them as lists of the possible |
914 | numbers in a given square, or anything else you feel like. |
915 | |
916 | To erase a single pencil mark, right-click in the square and type |
917 | the same number again. |
918 | |
919 | All pencil marks in a square are erased when you left-click and type |
920 | a number, or when you left-click and press space. Right-clicking and |
921 | pressing space will also erase pencil marks. |

927 | Solo allows you to configure two separate dimensions of the puzzle |
6ae37301 |
928 | grid on the \q{Type} menu: the number of columns, and the number of |
929 | rows, into which the main grid is divided. (The size of a block is |
930 | the inverse of this: for example, if you select 2 columns and 3 rows, |
931 | each actual block will have 3 columns and 2 rows.) |
1d8e8ad8 |
932 | |

933 | You can also configure the type of symmetry shown in the generated |
934 | puzzles. More symmetry makes the puzzles look prettier but may also |
935 | make them easier, since the symmetry constraints can force more |
936 | clues than necessary to be present. Completely asymmetric puzzles |
937 | have the freedom to contain as few clues as possible. |
938 | |
7c568a48 |
939 | Finally, you can configure the difficulty of the generated puzzles. |
940 | Difficulty levels are judged by the complexity of the techniques of |
941 | deduction required to solve the puzzle: each level requires a mode |
942 | of reasoning which was not necessary in the previous one. In |
943 | particular, on difficulty levels \q{Trivial} and \q{Basic} there |
944 | will be a square you can fill in with a single number at all times, |
945 | whereas at \q{Intermediate} level and beyond you will have to make |
946 | partial deductions about the \e{set} of squares a number could be in |
e28d0584 |
947 | (or the set of numbers that could be in a square). |
948 | \#{Advanced, Extreme?} |
949 | At \q{Unreasonable} level, even this is not enough, and you will |

950 | eventually have to make a guess, and then backtrack if it turns out |
951 | to be wrong. |

953 | Generating difficult puzzles is itself difficult: if you select one |
954 | of the higher difficulty levels, Solo may have to make many attempts |
955 | at generating a puzzle before it finds one hard enough for you. Be |
956 | prepared to wait, especially if you have also configured a large |
957 | puzzle size. |

961 | |
962 | \cfg{winhelp-topic}{games.mines} |
963 | |
964 | You have a grid of covered squares, some of which contain mines, but |
965 | you don't know which. Your job is to uncover every square which does |
966 | \e{not} contain a mine. If you uncover a square containing a mine, |
967 | you lose. If you uncover a square which does not contain a mine, you |
968 | are told how many mines are contained within the eight surrounding |
969 | squares. |
970 | |
971 | This game needs no introduction; popularised by Windows, it is |
972 | perhaps the single best known desktop puzzle game in existence. |
973 | |
974 | This version of it has an unusual property. By default, it will |
975 | generate its mine positions in such a way as to ensure that you |
976 | never need to \e{guess} where a mine is: you will always be able to |
977 | deduce it somehow. So you will never, as can happen in other |
978 | versions, get to the last four squares and discover that there are |
979 | two mines left but you have no way of knowing for sure where they |
980 | are. |
981 | |
982 | \H{mines-controls} \I{controls, for Mines}Mines controls |
983 | |
984 | This game is played with the mouse. |
985 | |
986 | If you left-click in a covered square, it will be uncovered. |
987 | |
988 | If you right-click in a covered square, it will place a flag which |
989 | indicates that the square is believed to be a mine. Left-clicking in |
990 | a marked square will not uncover it, for safety. You can right-click |
991 | again to remove a mark placed in error. |
992 | |
993 | If you left-click in an \e{uncovered} square, it will \q{clear |
994 | around} the square. This means: if the square has exactly as many |
995 | flags surrounding it as it should have mines, then all the covered |
996 | squares next to it which are \e{not} flagged will be uncovered. So |
997 | once you think you know the location of all the mines around a |
998 | square, you can use this function as a shortcut to avoid having to |
999 | click on each of the remaining squares one by one. |
1000 | |
1001 | If you uncover a square which has \e{no} mines in the surrounding |
1002 | eight squares, then it is obviously safe to uncover those squares in |
1003 | turn, and so on if any of them also has no surrounding mines. This |
1004 | will be done for you automatically; so sometimes when you uncover a |
1005 | square, a whole new area will open up to be explored. |

1011 | in question (unlike most other implementations, which reveal all of |
1012 | them). You can then Undo your fatal move and continue playing if you |
1013 | like. The program will track the number of times you died (and Undo |
1014 | will not reduce that counter), so when you get to the end of the |
1015 | game you know whether or not you did it without making any errors. |
1016 | |

1407 | |
1408 | \cfg{winhelp-topic}{games.blackbox} |
1409 | |
1410 | A number of balls are hidden in a rectangular arena. You have to |
1411 | deduce the positions of the balls by firing lasers from positions |
1412 | on the edge of the arena and observing how they are deflected. |
1413 | |
1414 | Lasers will fire straight until they hit the opposite side of the |
1415 | arena (at which point they emerge), unless affected by balls in one of |
1416 | the following ways: |
1417 | |
1418 | \b A laser that hits a ball head-on is absorbed and will never re-emerge. |
1419 | This includes lasers that meet a ball on the first rank of the arena. |
1420 | |
1421 | \b A laser with a ball to its front-left square gets deflected 90 degrees |
1422 | to the right. |
1423 | |
1424 | \b A laser with a ball to its front-right square gets similarly deflected |
1425 | to the left. |
1426 | |
1427 | \b A laser that would re-emerge from the entry location is considered to be |
ebf54ec9 |
1428 | \q{reflected}. |
bf7ebf5a |
1429 | |
a4c9750f |
1430 | \b A laser which would get deflected before entering the arena (down the |
1431 | \q{firing range}) by a ball to the front-left or front-right of its |
1432 | entry point is also considered to be \q{reflected}. |
bf7ebf5a |
1433 | |
ebf54ec9 |
1434 | Lasers that are reflected appear as a \q{R}; lasers that hit balls |
1435 | dead-on appear as \q{H}. Otherwise, a number appears at the firing point |
bf7ebf5a |
1436 | and the location where the laser emerges (this number is unique to |
1437 | that shot). |
1438 | |
1439 | You can place guesses as to the location of the balls, based on the |
1440 | entry and exit patterns of the lasers; once you have placed enough |
1441 | balls a button appears enabling you to have your guesses checked. |
1442 | |
1443 | Here is a diagram showing how the positions of balls can create each |
1444 | of the laser behaviours shown above: |
1445 | |
1446 | \c 1RHR---- |
1447 | \c |..O.O...| |
1448 | \c 2........3 |
1449 | \c |........| |
1450 | \c |........| |
1451 | \c 3........| |
1452 | \c |......O.| |
1453 | \c H........| |
1454 | \c |.....O..| |
1455 | \c 12-RH--- |
1456 | |
1457 | As shown, it is possible for a ball to receive multiple reflections |
1458 | before re-emerging (see turn 3). Similarly, a ball may be reflected |
ebf54ec9 |
1459 | (possibly more than once) before receiving a hit (the \q{H} on the |
bf7ebf5a |
1460 | left side of the example). |
1461 | |
1462 | Note that any layout with more that 4 balls may have a non-unique |
1463 | solution. The following diagram illustrates this; if you know the |
1464 | board contains 5 balls, it is impossible to determine where the fifth |
1465 | ball is (possible positions marked with an x): |
1466 | |
1467 | \c -------- |
1468 | \c |........| |
1469 | \c |........| |
1470 | \c |..O..O..| |
1471 | \c |...xx...| |
1472 | \c |...xx...| |
1473 | \c |..O..O..| |
1474 | \c |........| |
1475 | \c |........| |
1476 | \c -------- |
1477 | |
1478 | For this reason when you have your guesses checked the game will |
1479 | check that your solution \e{produces the same results} as the |
1480 | computer's, rather than that your solution is identical to the |
1481 | computer's. So in the above example, you could put the fifth ball at |
1482 | \e{any} of the locations marked with an x, and you would still win. |

1490 | To fire a laser, left-click in a square around the side of the arena. |
1491 | The results will be displayed immediately. Lasers may not be fired |
1492 | twice (because the results will never change). Holding down the left |
1493 | button will highlight the current go (or a previous go) to confirm the |
1494 | exit point for that laser, if applicable. |
1495 | |
1496 | To guess the location of a ball, left-click within the arena and a |
1497 | black circle will appear marking the guess; to remove the guessed ball |
1498 | click again. |
1499 | |
1500 | Locations in the arena may be locked against modification by |
1501 | right-clicking; whole rows and columns may be similarly locked by |
1502 | right-clicking in the laser firing range above/below that column, or |
1503 | to the left/right of that row. |
1504 | |
1505 | When an appropriate number of balls have been guessed a button will |

1507 | your guesses. |

1509 | If you click the \q{mark} button and your guesses are not correct, |
1510 | the game will show you as little information as possible to |
1511 | demonstrate this to you, so you can try again. If your ball |
1512 | positions are not consistent with the laser paths you already know |
1513 | about, one laser path will be circled to indicate that it proves you |
1514 | wrong. If your positions match all the existing laser paths but are |
1515 | still wrong, one new laser path will be revealed (written in red) |
1516 | which is not consistent with your current guesses. |
1517 | |
1518 | If you decide to give up completely, you can select Solve to reveal |
1519 | the actual ball positions. At this point, correctly-placed balls |
1520 | will be displayed as filled black circles; incorrectly-placed balls |
1521 | are displayed as filled black circles with red crosses, and missing |
1522 | balls are filled red circles. In addition, a red circle marks any |
1523 | laser you had already fired which is not consistent with your ball |
1524 | layout (just as when you press the mark button), and red text marks |
bf7ebf5a |
1525 | any laser you \e{could} have fired in order to distinguish your ball |

1700 | You are given a map consisting of a number of regions. Your task is |
1701 | to colour each region with one of four colours, in such a way that |
1702 | no two regions sharing a boundary have the same colour. You are |
1703 | provided with some regions already coloured, sufficient to make the |
1704 | remainder of the solution unique. |
1705 | |
1706 | Only regions which share a length of border are required to be |
1707 | different colours. Two regions which meet at only one \e{point} |
1708 | (i.e. are diagonally separated) may be the same colour. |
1709 | |
1710 | I believe this puzzle is original; I've never seen an implementation |
bb219ea1 |
1711 | of it anywhere else. The concept of a \i{four-colouring} puzzle was |
c51c7de6 |
1712 | suggested by Owen Dunn; credit must also go to Nikoli and to Verity |
1713 | Allan for inspiring the train of thought that led to me realising |
1714 | Owen's suggestion was a viable puzzle. Thanks also to Gareth Taylor |
1715 | for many detailed suggestions. |

1830 | You are a small green ball sitting in a grid full of obstacles. Your |
1831 | aim is to collect all the gems without running into any mines. |
1832 | |
1833 | You can move the ball in any orthogonal \e{or diagonal} direction. |
1834 | Once the ball starts moving, it will continue until something stops |
1835 | it. A wall directly in its path will stop it (but if it is moving |
1836 | diagonally, it will move through a diagonal gap between two other |
1837 | walls without stopping). Also, some of the squares are \q{stops}; |
1838 | when the ball moves on to a stop, it will stop moving no matter what |
1839 | direction it was going in. Gems do \e{not} stop the ball; it picks |
1840 | them up and keeps on going. |
1841 | |
1842 | Running into a mine is fatal. Even if you picked up the last gem in |
1843 | the same move which then hit a mine, the game will count you as dead |
1844 | rather than victorious. |
1845 | |
1846 | This game was originally implemented for Windows by Ben Olmstead |
1847 | \k{bem}, who was kind enough to release his source code on request |
1848 | so that it could be re-implemented for this collection. |

1858 | You can move the ball in any of the eight directions using the |

1863 | If you use the \q{Solve} function on this game, the program will |

1865 | gems and returns to the current position. A hint arrow will appear |
1866 | on the ball indicating the direction in which you should move to |
1867 | begin on this path. If you then move in that direction, the arrow |
1868 | will update to indicate the next direction on the path. You can also |
1869 | press Space to automatically move in the direction of the hint |
1870 | arrow. If you move in a different direction from the one shown by |
1871 | the arrow, the hint arrows will stop appearing because you have |

1950 | |
1951 | You have a set of islands distributed across the playing area. Each |
1952 | island contains a number. Your aim is to connect the islands |
1953 | together with bridges, in such a way that: |
1954 | |
1955 | \b Bridges run horizontally or vertically. |
1956 | |
1957 | \b The number of bridges terminating at any island is equal to the |
1958 | number written in that island. |
1959 | |
1960 | \b Two bridges may run in parallel between the same two islands, but |
1961 | no more than two may do so. |
1962 | |
1963 | \b No bridge crosses another bridge. |
1964 | |
1965 | \b All the islands are connected together. |
1966 | |
1967 | There are some configurable alternative modes, which involve |
1968 | changing the parallel-bridge limit to something other than 2, and |
1969 | introducing the additional constraint that no sequence of bridges |
1970 | may form a loop from one island back to the same island. The rules |
1971 | stated above are the default ones. |

1984 | To place a bridge between two islands, click the mouse down on one |
1985 | island and drag it towards the other. You do not need to drag all |
1986 | the way to the other island; you only need to move the mouse far |
1987 | enough for the intended bridge direction to be unambiguous. (So you |
1988 | can keep the mouse near the starting island and conveniently throw |
1989 | bridges out from it in many directions.) |
1990 | |
1991 | Doing this again when a bridge is already present will add another |
1992 | parallel bridge. If there are already as many bridges between the |
1993 | two islands as permitted by the current game rules (i.e. two by |
1994 | default), the same dragging action will remove all of them. |
1995 | |
1996 | If you want to remind yourself that two islands definitely \e{do |
1997 | not} have a bridge between them, you can right-drag between them in |
1998 | the same way to draw a \q{non-bridge} marker. |
1999 | |
2000 | If you think you have finished with an island (i.e. you have placed |
2001 | all its bridges and are confident that they are in the right |
2002 | places), you can mark the island as finished by left-clicking on it. |
2003 | This will highlight it and all the bridges connected to it, and you |
2004 | will be prevented from accidentally modifying any of those bridges |
2005 | in future. Left-clicking again on a highlighted island will unmark |
2006 | it and restore your ability to modify it. |
2007 | |
2008 | Violations of the puzzle rules will be marked in red: |
2009 | |
2010 | \b An island with too many bridges will be highlighted in red. |
2011 | |
2012 | \b An island with too few bridges will be highlighted in red if it |
2013 | is definitely an error (as opposed to merely not being finished |
2014 | yet): if adding enough bridges would involve having to cross another |
2015 | bridge or remove a non-bridge marker, or if the island has been |
2016 | highlighted as complete. |
2017 | |
2018 | \b A group of islands and bridges may be highlighted in red if it is |
2019 | a closed subset of the puzzle with no way to connect it to the rest |
2020 | of the islands. For example, if you directly connect two 1s together |
2021 | with a bridge and they are not the only two islands on the grid, |
2022 | they will light up red to indicate that such a group cannot be |
2023 | contained in any valid solution. |
2024 | |
2025 | \b If you have selected the (non-default) option to disallow loops |
2026 | in the solution, a group of bridges which forms a loop will be |

2124 | pressing space will also erase pencil marks. |

2140 | level, there are no greater-than signs (the puzzle is to solve the |
2141 | Latin square only); at Recursive level backtracking will be required |
2142 | (but the solution should still be unique); the levels in between |
2143 | require increasingly complex reasoning to avoid having to backtrack. |

2151 | You have a rectangular grid containing a number of dots. Your aim is |
2152 | to draw edges along the grid lines which divide the rectangle into |
2153 | regions in such a way that every region is 180\u00b0{-degree} |
2154 | rotationally symmetric, and contains exactly one dot which is |
2155 | located at its centre of symmetry. |
2156 | |
2157 | This puzzle was invented by \i{Nikoli} \k{nikoli-galaxies}, under |
a799e87f |
2158 | the name \q{Tentai Show}; its name is commonly translated into |
2159 | English as \q{Spiral Galaxies}. |

2167 | Left-click on any grid line to draw an edge if there isn't one |
2168 | already, or to remove one if there is. When you create a valid |
2169 | region (one which is closed, contains exactly one dot, is |
2170 | 180\u00b0{-degree} symmetric about that dot, and contains no |
2171 | extraneous edges inside it) it will be highlighted automatically; so |
2172 | your aim is to have the whole grid highlighted in that way. |
2173 | |
2174 | During solving, you might know that a particular grid square belongs |
2175 | to a specific dot, but not be sure of where the edges go and which |
2176 | other squares are connected to the dot. In order to mark this so you |
2177 | don't forget, you can right-click on the dot and drag, which will |
2178 | create an arrow marker pointing at the dot. Drop that in a square of |
2179 | your choice and it will remind you which dot it's associated with. |
2180 | You can also right-click on existing arrows to pick them up and move |
2181 | them, or destroy them by dropping them off the edge of the grid. |
2182 | (Also, if you're not sure which dot an arrow is pointing at, you can |
2183 | pick it up and move it around to make it clearer. It will swivel |
2184 | constantly as you drag it, to stay pointed at its parent dot.) |
