+You have a square grid, which is divided into as many equally sized
+sub-blocks as the grid has rows. Each square must be filled in with
+a digit from 1 to the size of the grid, in such a way that
\b every row contains only one occurrence of each digit
\b every block contains only one occurrence of each digit.
+\b (optionally, by default off) each of the square's two main
+diagonals contains only one occurrence of each digit.
+
You are given some of the numbers as clues; your aim is to place the
rest of the numbers correctly.
-The default puzzle size is 3\by\.3 (a 9\by\.9 actual grid, divided
-into nine 3\by\.3 blocks). You can also select sizes with
-rectangular blocks instead of square ones, such as 2\by\.3 (a
-6\by\.6 grid divided into six 3\by\.2 blocks).
+Under the default settings, the sub-blocks are square or
+rectangular. The default puzzle size is 3\by\.3 (a 9\by\.9 actual
+grid, divided into nine 3\by\.3 blocks). You can also select sizes
+with rectangular blocks instead of square ones, such as 2\by\.3 (a
+6\by\.6 grid divided into six 3\by\.2 blocks). Alternatively, you
+can select \q{jigsaw} mode, in which the sub-blocks are arbitrary
+shapes which differ between individual puzzles.
If you select a puzzle size which requires more than 9 digits, the
additional digits will be letters of the alphabet. For example, if
the inverse of this: for example, if you select 2 columns and 3 rows,
each actual block will have 3 columns and 2 rows.)
+If you tick the \q{X} checkbox, Solo will apply the optional extra
+constraint that the two main diagonals of the grid also contain one
+of every digit. (This is sometimes known as \q{Sudoku-X} in
+newspapers.) In this mode, the squares on the two main diagonals
+will be shaded slightly so that you know it's enabled.
+
+If you tick the \q{Jigsaw} checkbox, Solo will generate randomly
+shaped sub-blocks. In this mode, the actual grid size will be taken
+to be the product of the numbers entered in the \q{Columns} and
+\q{Rows} boxes. There is no reason why you have to enter a number
+greater than 1 in both boxes; Jigsaw mode has no constraint on the
+grid size, and it can even be a prime number if you feel like it.
+
You can also configure the type of symmetry shown in the generated
puzzles. More symmetry makes the puzzles look prettier but may also
make them easier, since the symmetry constraints can force more

+You are given a grid of dots, marked with yellow lines to indicate
+which dots you are allowed to connect directly together. Your aim is
+to use some subset of those yellow lines to draw a single unbroken
loop from dot to dot within the grid.
-Some of the square spaces between the dots contain numbers. These
-numbers indicate how many of the four edges of that square are part
-of the loop. The loop you draw must correctly satisfy all of these

+\C{unequal} \i{Unequal}
+
+\cfg{winhelp-topic}{games.unequal}
+
+You have a square grid; each square may contain a digit from 1 to
+the size of the grid, and some squares have greater-than signs between
+them. Your aim is to fully populate the grid with numbers such that:
+
+\b Each row contains only one occurrence of each digit
+
+\b Each column contains only one occurrence of each digit
+
+\b All the greater-than signs are satisfied.
+
+In \q{Trivial} mode (available via the \q{Custom} game type
+selector), there are no greater-than signs; the puzzle is to solve
+the \i{Latin square} only.
+
+At the time of writing, this puzzle is appearing in the Guardian
+weekly under the name \q{\i{Futoshiki}}.

+\IM{Unequal controls} controls, for Unequal
+
+Unequal shares much of its control system with Solo.
+
+To play Unequal, simply click the mouse in any empty square and then
+type a digit or letter on the keyboard to fill that square. If you
+make a mistake, click the mouse in the incorrect square and press
+Space to clear it again (or use the Undo feature).
+
+If you \e{right}-click in a square and then type a number, that
+number will be entered in the square as a \q{pencil mark}. You can
+have pencil marks for multiple numbers in the same square.
+
+The game pays no attention to pencil marks, so exactly what you use
+them for is up to you: you can use them as reminders that a
+particular square needs to be re-examined once you know more about a
+particular number, or you can use them as lists of the possible
+numbers in a given square, or anything else you feel like.
+
+To erase a single pencil mark, right-click in the square and type
+the same number again.
+
+All pencil marks in a square are erased when you left-click and type
+a number, or when you left-click and press space. Right-clicking and
+pressing space will also erase pencil marks.

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

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

+\C{filling} \i{Filling}
+
+\cfg{winhelp-topic}{games.filling}
+
+You have a grid of squares, some of which contain digits, and the
+rest of which are empty. Your job is to fill in digits in the empty
+squares, in such a way that each connected region of squares all
+containing the same digit has an area equal to that digit.
+
+(\q{Connected region}, for the purposes of this game, does not count
+diagonally separated squares as adjacent.)
+
+For example, it follows that no square can contain a zero, and that
+two adjacent squares can not both contain a one. No region has an
+area greater than 9 (because then its area would not be a single
+digit).

+
+To play Filling, simply click the mouse in any empty square and then
