33 | \C{intro} Introduction |
34 | |
35 | I wrote this collection because I thought there should be more small |
36 | desktop toys available: little games you can pop up in a window and |
37 | play for two or three minutes while you take a break from whatever |
8a771ea7 |
38 | else you were doing. And I was also annoyed that every time I found |
39 | a good game on (say) \i{Unix}, it wasn't available the next time I |
40 | was sitting at a \i{Windows} machine, or vice versa; so I arranged |
41 | that everything in my personal puzzle collection will happily run on |
42 | both, and have more recently done a port to Mac OS X as well. When I |
43 | find (or perhaps invent) further puzzle games that I like, they'll |
44 | be added to this collection and will immediately be available on |
45 | both platforms. And if anyone feels like writing any other front |
46 | ends - PocketPC, Mac OS pre-10, or whatever it might be - then all |
47 | the games in this framework will immediately become available on |
48 | another platform as well. |
e91825f8 |
49 | |
50 | The actual games in this collection were mostly not my invention; I |
51 | saw them elsewhere, and rewrote them in a form that was more |
52 | convenient for me. I do not claim credit, in general, for inventing |
53 | the rules of any of these puzzles; all I claim is authorship of the |
54 | code (or at least those parts of the code that weren't contributed |
55 | by other people!). |
56 | |
57 | This collection is distributed under the \i{MIT licence} (see |
58 | \k{licence}). This means that you can do pretty much anything you like |
59 | with the game binaries or the code, except pretending you wrote them |
60 | yourself, or suing me if anything goes wrong. |
61 | |
62 | The most recent versions, and \i{source code}, can be found at |

71 | \ii{Patches} are welcome. Especially if they provide a new front end |
72 | (to make all these games run on another platform), or a new game. |
73 | |
74 | |
75 | \C{common} \ii{Common features} |
76 | |
77 | This chapter describes features that are common to all the games. |
78 | |
79 | \H{common-actions} \I{controls}Common actions |
80 | |
81 | These actions are all available from the \I{Game menu}\q{Game} menu |
82 | and via \I{keys}keyboard shortcuts, in addition to any game-specific |
83 | actions. |
84 | |
85 | \dt \ii\e{New game} (\q{N}, Ctrl+\q{N}) |
86 | |
87 | \dd Starts a new game, with a random initial state. |
88 | |
89 | \dt \ii\e{Restart game} (\q{R}) |
90 | |
91 | \dd Resets the current game to its initial state. Undo is lost. |
92 | |
93 | \dt \ii\e{Undo} (\q{U}, Ctrl+\q{Z}, Ctrl+\q{_}) |
94 | |
95 | \dd Undoes a single move. (You can undo moves back to the start of the |
96 | game.) |
97 | |
98 | \dt \ii\e{Redo} (Ctrl+\q{R}) |
99 | |
100 | \dd Redoes a previous undone move. |
101 | |
102 | \dt \I{exit}\ii\e{Quit} (\q{Q}, Ctrl+\q{Q}) |
103 | |
104 | \dd Closes the application entirely. |
105 | |
106 | \H{common-id} Recreating games with the \ii{game ID} |
107 | |
108 | The \q{\i{Specific...}} option from the \I{Game menu}\q{Game} menu |
109 | lets you see a short string (the \q{game ID}) that captures the |
110 | initial state of the current game. |
111 | |
112 | The precise \I{ID format}format of the ID is specific to each game. |
113 | It consists of two parts delimited by a colon (e.g., \c{c4x4:4F01,0}); |
114 | the first part encodes \i\e{parameters} (such as grid size), while the |
115 | second part encodes a \i\e{seed}, which determines the \i{initial |
116 | state} of the game within those parameters. |
117 | |
118 | You can specify a new ID (or just a seed) here. Pressing \q{OK} starts |
119 | a new game with the specified ID (whether you changed it or not). |
120 | Pressing \q{Cancel} returns to the current game. |
121 | |
122 | You can also use the game ID (or just the encoded parameters) as a |
123 | \i{command line} argument; see \k{common-cmdline} for more detail. |
124 | |
125 | Game IDs are portable across platforms; you can use a game ID |
126 | generated by the Windows version of a game on the Unix version, etc. |
127 | |
128 | \H{common-type} The \q{Type} menu |
129 | |
130 | The \I{Type menu}\q{Type} menu, if present, may contain a list of |
131 | \i{preset} game settings. Selecting one of these will start a new |
132 | random game with the parameters specified. |
133 | |
134 | The \q{Type} menu may also contain a \q{\i{Custom...}} option which |
135 | allows you to fine-tune game \i{parameters}. The parameters available |
136 | are specific to each game and are described in the following sections. |
137 | |
138 | \H{common-cmdline} Specifying game parameters on the \i{command line} |
139 | |
8a771ea7 |
140 | (This section does not apply to the Mac OS X version.) |
141 | |
e91825f8 |
142 | The games in this collection deliberately do not ever save |
143 | information on to the computer they run on: they have no high score |
144 | tables and no saved preferences. (This is because I expect at least |
145 | some people to play them at work, and those people will probably |
146 | appreciate leaving as little evidence as possible!) |
147 | |
148 | However, if you do want to arrange for one of these games to default |
149 | to a particular set of parameters, you can specify them on the |
150 | command line. |
151 | |
152 | The easiest way to do this is to set up the parameters you want |
153 | using the \q{Type} menu (see \k{common-type}), and then to select |
154 | \q{Specific} from the \q{Game} menu (see \k{common-id}). The text in |
155 | the \q{Game ID} box will be composed of two parts, separated by a |
156 | colon. The first of these parts represents the game parameters (the |
157 | size of the playing area, for example, and anything else you set |
158 | using the \q{Type} menu). |
159 | |
160 | If you run the game with just that parameter text on the command |
161 | line, it will start up with the settings you specified. |
162 | |
163 | For example: if you run Cube (see \k{cube}), select \q{Octahedron} |
164 | from the \q{Type} menu, and then go to the game ID selection, you |
165 | will see a string of the form \cq{o2x2:911A81,10}. Take only the |
166 | part before the colon (\cq{o2x2}), and start Cube with that text on |
167 | the command line: \cq{cube o2x2}. |
168 | |
169 | If you copy the \e{entire} game ID on to the command line, the game |
170 | will start up in the specific game that was described. This is |
171 | occasionally a more convenient way to start a particular game ID |
172 | than by pasting it into the game ID selection box. |
173 | |
174 | \C{net} \i{Net} |
175 | |
176 | \cfg{winhelp-topic}{games.net} |
177 | |
178 | (\e{Note:} the \i{Windows} version of this game is called |
179 | \i\cw{NETGAME.EXE} to avoid clashing with Windows's own \cw{NET.EXE}.) |
180 | |
181 | I originally saw this in the form of a Flash game called \i{FreeNet} |
182 | \k{FreeNet}, written by Pavils Jurjans. The computer prepares a |
183 | network by connecting up the centres of squares in a grid, and then |
184 | shuffles the network by rotating every tile randomly. Your job is to |
185 | rotate it all back into place. The successful solution will be an |
186 | entirely connected network, with no closed loops. \#{Is it also true |
187 | that a correct solution will not contain any cycles?} As a visual aid, |
188 | all tiles which are connected to the one in the middle are |
189 | highlighted. |
190 | |

193 | \H{net-controls} \i{Net controls} |
194 | |
195 | \IM{Net controls} controls, for Net |
196 | \IM{Net controls} keys, for Net |
197 | \IM{Net controls} shortcuts (keyboard), for Net |
198 | |
199 | This game can be played with either the keyboard or the mouse. The |
200 | controls are: |
201 | |
202 | \dt \e{Select tile}: mouse pointer, arrow keys |
203 | |
204 | \dt \e{Rotate tile anticlockwise}: left mouse button, \q{A} key |
205 | |
206 | \dt \e{Rotate tile clockwise}: right mouse button, \q{D} key |
207 | |
208 | \dt \e{Lock (or unlock) tile}: middle mouse button, shift-click, \q{S} key |
209 | |
210 | \dd You can lock a tile once you're sure of its orientation. You can |
211 | also unlock it again, but while it's locked you can't accidentally |
212 | turn it. |
213 | |
cbb5549e |
214 | \dt \e{Jumble tiles}: \q{J} key |
215 | |
216 | \dd This key turns all tiles that are not locked to random |
217 | orientations. |
218 | |
e91825f8 |
219 | (All the actions described in \k{common-actions} are also available.) |
220 | |
221 | \H{net-params} \I{parameters, for Net}Net parameters |
222 | |
223 | These parameters are available from the \q{Custom...} option on the |
224 | \q{Type} menu. |
225 | |
226 | \dt \e{Width}, \e{Height} |
227 | |
228 | \dd Size of grid in tiles. |
229 | |
230 | \dt \e{Walls wrap around} |
231 | |
232 | \dd If checked, flow can pass from the left edge to the right edge, |
233 | and from top to bottom, and vice versa. |
234 | |
235 | \dt \e{Barrier probability} |
236 | |
237 | \dd A number between 0.0 and 1.0 controlling whether an immovable |
238 | barrier is placed between two tiles to prevent flow between them (a |
239 | higher number gives more barriers). Since barriers are immovable, they |
240 | act as constraints on the solution (i.e., hints). |
241 | |
242 | \lcont{ |
243 | |
244 | The grid generation in Net has been carefully arranged so that the |
245 | barriers are independent of the rest of the grid. This means that if |
246 | you change the \e{Barrier probability} parameter, and then re-enter |
247 | the same game ID you were playing before (see \k{common-id}), you |
248 | should see exactly the same starting grid, with the only change |
249 | being the number of barriers. So if you're stuck on a particular |
250 | grid and need a hint, you could start up another instance of Net, |
251 | set up the same parameters but a higher barrier probability, and |
252 | enter the game seed from the original Net window. |
253 | |
254 | } |
255 | |
256 | \C{cube} \i{Cube} |
257 | |
258 | \cfg{winhelp-topic}{games.cube} |
259 | |
260 | This is another one I originally saw as a web game. This one was a |
261 | Java game \k{cube-java-game}, by Paul Scott. You have a grid of 16 |
262 | squares, six of which are blue; on one square rests a cube. Your move |
263 | is to use the arrow keys to roll the cube through 90 degrees so that |
264 | it moves to an adjacent square. If you roll the cube on to a blue |
265 | square, the blue square is picked up on one face of the cube; if you |
266 | roll a blue face of the cube on to a non-blue square, the blueness is |
267 | put down again. (In general, whenever you roll the cube, the two faces |
268 | that come into contact swap colours.) Your job is to get all six blue |
269 | squares on to the six faces of the cube at the same time. Count your |
270 | moves and try to do it in as few as possible. |
271 | |
272 | Unlike the original Java game, my version has an additional feature: |
273 | once you've mastered the game with a cube rolling on a square grid, |
274 | you can change to a triangular grid and roll any of a tetrahedron, an |
275 | octahedron or an icosahedron. |
276 | |
277 | \B{cube-java-game} \W{http://www3.sympatico.ca/paulscott/cube/cube.htm}\cw{http://www3.sympatico.ca/paulscott/cube/cube.htm} |
278 | |
279 | \H{cube-controls} \i{Cube controls} |
280 | |
281 | \IM{Cube controls} controls, for Cube |
282 | \IM{Cube controls} keys, for Cube |
283 | \IM{Cube controls} shortcuts (keyboard), for Cube |
284 | |
285 | This game is played with the keyboard. The arrow keys are used to roll the |
286 | cube (or other solid). |
287 | |
288 | On the triangular grids, the mapping of arrow keys to directions is |
289 | more approximate. Vertical movement is disallowed where it doesn't |
290 | make sense. The four keys surrounding the arrow keys on the numeric |
291 | keypad (\q{7}, \q{9}, \q{1}, \q{3}) can be used for diagonal movement. |
292 | |
293 | (All the actions described in \k{common-actions} are also available.) |
294 | |
295 | \H{cube-params} \I{parameters, for Cube}Cube parameters |
296 | |
297 | These parameters are available from the \q{Custom...} option on the |
298 | \q{Type} menu. |
299 | |
300 | \dt \e{Type of solid} |
301 | |
302 | \dd Selects the solid to roll (and hence the shape of the grid): |
303 | tetrahedron, cube, octahedron, or icosahedron. |
304 | |
305 | \dt \e{Width / top}, \e{Height / bottom} |
306 | |
307 | \dd On a square grid, horizontal and vertical dimensions. On a |
308 | triangular grid, the number of triangles on the top and bottom rows |
309 | respectively. |
310 | |
311 | |
312 | \C{fifteen} \i{Fifteen} |
313 | |
314 | \cfg{winhelp-topic}{games.fifteen} |
315 | |
1d8e8ad8 |
316 | The old ones are the best: this is the good old \q{\i{15-puzzle}} |
317 | with sliding tiles. You have a 4\by\.4 square grid; 15 squares |
318 | contain numbered tiles, and the sixteenth is empty. Your move is to |
319 | choose a tile next to the empty space, and slide it into the space. |
320 | The aim is to end up with the tiles in numerical order, with the |
321 | space in the bottom right (so that the top row reads 1,2,3,4 and the |
322 | bottom row reads 13,14,15,\e{space}). |
e91825f8 |
323 | |
324 | \H{fifteen-controls} \i{Fifteen controls} |
325 | |
326 | \IM{Fifteen controls} controls, for Fifteen |
327 | \IM{Fifteen controls} keys, for Fifteen |
328 | \IM{Fifteen controls} shortcuts (keyboard), for Fifteen |
329 | |
330 | This game can be controlled with the mouse or the keyboard. |
331 | |
332 | A left-click with the mouse in the row or column containing the empty |
333 | space will move as many tiles as necessary to move the space to the |
334 | mouse pointer. |
335 | |
336 | The arrow keys will move a tile adjacent to the space in the direction |
337 | indicated (moving the space in the \e{opposite} direction). |
338 | |
339 | (All the actions described in \k{common-actions} are also available.) |
340 | |
341 | \H{fifteen-params} \I{parameters, for Fifteen}Fifteen parameters |
342 | |
343 | The only options available from the \q{Custom...} option on the \q{Type} |
344 | menu are \e{Width} and \e{Height}, which are self-explanatory. (Once |
345 | you've changed these, it's not a \q{15-puzzle} any more, of course!) |
346 | |
347 | |
348 | \C{sixteen} \i{Sixteen} |
349 | |
350 | \cfg{winhelp-topic}{games.sixteen} |
351 | |
352 | Another sliding tile puzzle, visually similar to Fifteen (see |
353 | \k{fifteen}) but with a different type of move. This time, there is no |
354 | hole: all 16 squares on the grid contain numbered squares. Your move |
355 | is to shift an entire row left or right, or shift an entire column up |
356 | or down; every time you do that, the tile you shift off the grid |
357 | re-appears at the other end of the same row, in the space you just |
358 | vacated. To win, arrange the tiles into numerical order (1,2,3,4 on |
359 | the top row, 13,14,15,16 on the bottom). When you've done that, try |
360 | playing on different sizes of grid. |
361 | |
362 | I \e{might} have invented this game myself, though only by accident if |
363 | so (and I'm sure other people have independently invented it). I |
364 | thought I was imitating a screensaver I'd seen, but I have a feeling |
365 | that the screensaver might actually have been a Fifteen-type puzzle |
366 | rather than this slightly different kind. So this might be the one |
367 | thing in my puzzle collection which represents creativity on my part |
368 | rather than just engineering. |
369 | |
370 | \H{sixteen-controls} \I{controls, for Sixteen}Sixteen controls |
371 | |
372 | This game is played with the mouse. Left-clicking on an arrow will |
373 | move the appropriate row or column in the direction indicated. |
374 | Right-clicking will move it in the opposite direction. |
375 | |
376 | (All the actions described in \k{common-actions} are also available.) |
377 | |
378 | \H{sixteen-params} \I{parameters, for Sixteen}Sixteen parameters |
379 | |
380 | The only parameters available from the \q{Custom...} option on the |
381 | \q{Type} menu are \e{Width} and \e{Height}, which are |
382 | self-explanatory. |
383 | |
384 | |
385 | \C{rectangles} \i{Rectangles} |
386 | |
387 | \cfg{winhelp-topic}{games.rectangles} |
388 | |
389 | You have a grid of squares, with numbers written in some (but not all) |
390 | of the squares. Your task is to subdivide the grid into rectangles of |
391 | various sizes, such that (a) every rectangle contains exactly one |
392 | numbered square, and (b) the area of each rectangle is equal to the |
393 | number written in its numbered square. |
394 | |
395 | Credit for this game goes to the Japanese puzzle magazine \i{Nikoli} |
396 | \k{nikoli}; I've also seen a Palm implementation at \i{Puzzle Palace} |
397 | \k{puzzle-palace}. Unlike Puzzle Palace's implementation, my version |
398 | automatically generates random grids of any size you like. The quality |
399 | of puzzle design is therefore not quite as good as hand-crafted |
400 | puzzles would be (in particular, a unique solution cannot be |
401 | guaranteed), but on the plus side you get an inexhaustible supply of |
402 | puzzles tailored to your own specification. |

409 | |
410 | This game is played with the mouse. |
411 | |
412 | Left-click any edge to toggle it on or off, or click and drag to draw |
413 | an entire rectangle (or line) on the grid in one go (removing any |
414 | existing edges within that rectangle). |
415 | |
416 | When a rectangle of the correct size is completed, it will be shaded. |

aea3ed9a |
422 | The \q{Custom...} option on the \q{Type} menu offers you \e{Width} |
423 | and \e{Height} parameters, which are self-explanatory. |
424 | |
425 | \q{Expansion factor} is a mechanism for changing the type of grids |
426 | generated by the program. Some people prefer a grid containing a few |
427 | large rectangles to one containing many small ones. So you can ask |
428 | Rectangles to essentially generate a \e{smaller} grid than the size |
429 | you specified, and then to expand it by adding rows and columns. |
430 | |
431 | The default expansion factor of zero means that Rectangles will |
432 | simply generate a grid of the size you ask for, and do nothing |
433 | further. If you set an expansion factor of (say) 0.5, it means that |
434 | each dimension of the grid will be expanded to half again as big |
435 | after generation. In other words, the initial grid will be 2/3 the |
436 | size in each dimension, and will be expanded to its full size |
437 | without adding any more rectangles. |

439 | Setting an expansion factor of around 0.5 tends to make the game |
440 | more difficult, and also (in my experience) rewards a less deductive |
441 | and more intuitive playing style. If you set it \e{too} high, |
442 | though, the game simply cannot generate more than a few rectangles |
443 | to cover the entire grid, and the game becomes trivial. |

447 | |
448 | The expansion factor parameter, described in \k{rectangles-params}, |
449 | is not mentioned by default in the game ID (see \k{common-id}). So |
450 | if you set your expansion factor to (say) 0.75, and then you |
1d8e8ad8 |
451 | generate an 11\by\.11 grid, then the game ID will simply say |
aea3ed9a |
452 | \c{11x11:}\e{numbers}. This means that if you send the game ID to |
453 | another player and they paste it into their copy of Rectangles, |
454 | their game will not be automatically configured to use the same |
455 | expansion factor in any subsequent grids it generates. (I don't |
456 | think the average person examining a single grid sent to them by |
457 | another player would want their configuration modified to that |
458 | extent.) |
459 | |
460 | If you are specifying a game ID or game parameters on the command |
461 | line (see \k{common-cmdline}) and you do want to configure the |
462 | expansion factor, you can do it by suffixing the letter \cq{e} to |
463 | the parameters, followed by the expansion factor as a decimal |
464 | number. For example: |
465 | |
466 | \b \cq{rect 11x11e0.75} starts Rectangles with a grid size of |
467 | 11\u00d7{x}11 and an expansion factor of 0.75. |
468 | |
469 | \b \cq{rect 11x11e0.75:g11c6e5e4a2_4e9c3b3d3b5g2b6c4k4g30a8n3j1g6a2} |
470 | starts Rectangles with a grid size of 11\u00d7{x}11, an expansion |
471 | factor of 0.75, \e{and} a specific game selected. |

477 | This game was submitted by Richard Boulton. It combines the grid |
478 | generation of Net (see \k{net}) with the movement of Sixteen (see |
479 | \k{sixteen}): you have a Net grid, but instead of rotating tiles back |
480 | into place you have to slide them into place by moving a whole row at |
481 | a time. |
482 | |

483 | As in Sixteen, \I{controls, for Netslide}control is with the mouse. |
484 | See \k{sixteen-controls}. |

493 | You have a grid of squares, which must all be filled in either black |
494 | or white. Beside each row of the grid are listed the lengths of the |
495 | runs of black squares on that row; above each column are listed the |
496 | lengths of the runs of black squares in that column. Your aim is to |
497 | fill in the entire grid black or white. |
498 | |
499 | I first saw this puzzle form around 1995, under the name |
2e1e03ff |
500 | \q{\i{nonograms}}. I've seen it in various places since then, under |
b6b0369e |
501 | different names. |
502 | |
503 | Normally, puzzles of this type turn out to be a meaningful picture |
504 | of something once you've solved them. However, since this version |
505 | generates the puzzles automatically, they will just look like random |
506 | groupings of squares. (One user has suggested that this is actually |
507 | a \e{good} thing, since it prevents you from guessing the colour of |
508 | squares based on the picture, and forces you to use logic instead.) |
509 | The advantage, though, is that you never run out of them. |

513 | This game is played with the mouse. |
514 | |
515 | Left-click in a square to colour it black. Right-click to colour it |
516 | white. If you make a mistake, you can middle-click, or hold down |
517 | Shift while clicking with any button, to colour the square in the |
518 | default grey (meaning \q{undecided}) again. |
519 | |
520 | You can click and drag with the left or right mouse button to colour |
521 | a vertical or horizontal line of squares black or white at a time |
522 | (respectively). If you click and drag with the middle button, or |
523 | with Shift held down, you can colour a whole rectangle of squares |
524 | grey. |

536 | |
537 | You have a square grid, which is divided into square or rectangular |
538 | blocks. Each square must be filled in with a digit from 1 to the |
539 | size of the grid, in such a way that |
540 | |
541 | \b every row contains only one occurrence of each digit |
542 | |
543 | \b every column contains only one occurrence of each digit |
544 | |
545 | \b every block contains only one occurrence of each digit. |
546 | |
547 | You are given some of the numbers as clues; your aim is to place the |
548 | rest of the numbers correctly. |
549 | |
550 | The default puzzle size is 3\by\.3 (a 9\by\.9 actual grid, divided |
551 | into nine 3\by\.3 blocks). You can also select sizes with |
552 | rectangular blocks instead of square ones, such as 2\by\.3 (a |
553 | 6\by\.6 grid divided into six 3\by\.2 blocks). |
554 | |
555 | If you select a puzzle size which requires more than 9 digits, the |
556 | additional digits will be letters of the alphabet. For example, if |
557 | you select 3\by\.4 then the digits which go in your grid will be 1 |
558 | to 9, plus \cq{a}, \cq{b} and \cq{c}. |
559 | |
560 | I first saw this puzzle in \i{Nikoli} \k{nikoli}, although it's also |
561 | been popularised by various newspapers under the name \q{Sudoku} or |
562 | \q{Su Doku}. |

566 | To play Solo, simply click the mouse in any empty square and then |
567 | type a digit or letter on the keyboard to fill that square. If you |
568 | make a mistake, click the mouse in the incorrect square and press |
569 | Space to clear it again (or use the Undo feature). |

575 | Solo allows you to configure two separate dimensions of the puzzle |
576 | grid: the number of columns, and the number of rows, into which the |
577 | main grid is divided. (The size of a block is the inverse of this: |
578 | for example, if you select 2 columns and 3 rows, each actual block |
579 | will have 3 columns and 2 rows.) |
