+Pressing \q{h} or \q{?} will fill the current guess with a suggested

When the guess is complete, the smaller feedback pegs will be highlighted;
clicking on these (or moving the peg cursor to them with the arrow keys
you know that those will never be counted as part of the solution). This
is turned off by default.

Note that this doesn't allow blank pegs in the solution; if you really wanted
that, use one extra colour.

\dd Allows the solution (and the guesses) to contain colours more than once;
pressing the space bar will lay a line between the two squares.
Repeating either action removes the domino or line.

+
+\C{flood} \i{Flood}
+
+\cfg{winhelp-topic}{games.flood}
+
+You are given a grid of squares, coloured at random in multiple
+colours. In each move, you can flood-fill the top left square in a
+colour of your choice (i.e. every square reachable from the starting
+square by an orthogonally connected path of squares all the same
+colour will be filled in the new colour). As you do this, more and
+more of the grid becomes connected to the starting square.
+
+Your aim is to make the whole grid the same colour, in as few moves as
+possible. The game will set a limit on the number of moves, based on
+running its own internal solver. You win if you can make the whole
+grid the same colour in that many moves or fewer.
+
+I saw this game (with a fixed grid size, fixed number of colours, and
+fixed move limit) at \W{http://floodit.appspot.com}\cw{floodit.appspot.com}.
+
+\H{flood-controls} \I{controls, for Flood}Flood controls
+
+To play Flood, click the mouse in a square. The top left corner and
+everything connected to it will be flood-filled with the colour of the
+square you clicked. Clicking a square the same colour as the top left
+corner has no effect, and therefore does not count as a move.
+
+You can also use the cursor keys to move a cursor (outline black
+square) around the grid. Pressing the return key will fill the top
+left corner in the colour of the square under the cursor.
+
+(All the actions described in \k{common-actions} are also available.)

+\dd Number of colours used to fill the grid. Must be at least 3 (with
+two colours there would only be one legal move at any stage, hence no
+choice to make at all), and at most 10.
+
+\dt \e{Extra moves permitted}
+
+\dd Controls the difficulty of the puzzle, by increasing the move
+limit. In each new grid, Flood will run an internal solver to generate
+its own solution, and then the value in this field will be added to
+the length of Flood's solution to generate the game's move limit. So a
+value of 0 requires you to be just as efficient as Flood's automated
+solver, and a larger value makes it easier.
+
+\lcont{
+
+(Note that Flood's internal solver will not necessarily find the
+shortest possible solution, though I believe it's pretty close. For a
+real challenge, set this value to 0 and then try to solve a grid in
+\e{strictly fewer} moves than the limit you're given!)

+
+\C{tracks} \i{Tracks}
+
+\cfg{winhelp-topic}{games.tracks}
+
+You are given a grid of squares, some of which are filled with train
+tracks. You need to complete the track from A to B so that the rows and
+columns contain the same number of track segments as are indicated in the
+clues to the top and right of the grid.
+
+There are only straight and 90 degree curved rails, and the track may not
+cross itself.
+
+Tracks was contributed to this collection by James Harvey.
+
+\H{tracks-controls} \I{controls, for Tracks}Tracks controls
+
+Left-clicking on an edge between two squares adds a track segment between
+the two squares. Right-clicking on an edge adds a cross on the edge,
+indicating no track is possible there.
+
+Left-clicking in a square adds a colour indicator showing that you know the
+square must contain a track, even if you don't know which edges it crosses
+yet. Right-clicking in a square adds a cross indicating it contains no
+track segment.
+
+Left- or right-dragging between squares allows you to lay a straight line
+of is-track or is-not-track indicators, useful for filling in rows or
+columns to match the clue.

+\dd Controls the difficulty of the generated puzzle: at Tricky level,
+you are required to make more deductions regarding disregarding moves
+that would lead to impossible crossings later.
+
+\dt \e{Disallow consecutive 1 clues}
+
+\dd Controls whether the Tracks game generation permits two adjacent
+rows or columns to have a 1 clue, or permits the row or column of the
+track's endpoint to have a 1 clue. By default this is not permitted,
+to avoid long straight boring segments of track and make the games
+more twiddly and interesting. If you want to restore the possibility,
+turn this option off.
+
+
+\C{palisade} \i{Palisade}
+
+\cfg{winhelp-topic}{games.palisade}
+
+You're given a grid of squares, some of which contain numbers. Your
+goal is to subdivide the grid into contiguous regions, all of the same
+(given) size, such that each square containing a number is adjacent to
+exactly that many edges (including those between the inside and the
+outside of the grid).
