\C{intro} Introduction
I wrote this collection because I thought there should be more small

Note that this doesn't allow blank pegs in the solution; if you really wanted
that, use one extra colour.
+}
+
\dt \e{Allow duplicates}
\dd Allows the solution (and the guesses) to contain colours more than once;
likely it is to extend as far as it can, rather than choosing
somewhere closer.
+\lcont{
+
High expansion factors usually mean easier puzzles with fewer
possible islands; low expansion factors can create lots of
tightly-packed islands.

Pressing M will fill in a full set of pencil marks in every square
that does not have a main digit in it.
+Left-clicking a clue will mark it as done (grey it out), or unmark it

solving), and right-clicking again empties the domino.

You can also use the cursor keys to move a cursor around the grid.
Pressing the return key will lay a domino with a positive pole at that
position; pressing again reverses the polarity and then removes the

\dd Controls the difficulty of the generated puzzle. At Tricky level,
\b for any two white squares, there is a path between them using only
white squares.
-\b for each square with a number, that number denotes the number of

+\b for each square with a number, that number denotes the total number
+of white squares reachable from that square going in a straight line
+in any horizontal or vertical direction until hitting a wall or a

+\C{unruly} \i{Unruly}
+
+\cfg{winhelp-topic}{games.unruly}
+
+You are given a grid of squares, which you must colour either black or
+white. Some squares are provided as clues; the rest are left for you
+to fill in. Each row and column must contain the same number of black
+and white squares, and no row or column may contain three consecutive
+squares of the same colour.
+
+This puzzle type was invented by Adolfo Zanellati, under the name
+\q{Tohu wa Vohu}. See \k{janko-unruly} for more details.
+
+Unruly was contributed to this collection by Lennard Sprong.

+
+\H{unruly-controls} \I{controls, for Unruly}Unruly controls
+
+To play Unruly, click the mouse in a square to change its colour.
+Left-clicking an empty square will turn it black, and right-clicking
+will turn it white. Keep clicking the same button to cycle through the
+three possible states for the square. If you middle-click in a square
+it will be reset to empty.
+
+You can also use the cursor keys to move around the grid. Pressing the
+return or space keys will turn an empty square black or white
+respectively (and then cycle the colours in the same way as the mouse
+buttons), and pressing Backspace will reset a square to empty.
+
+(All the actions described in \k{common-actions} are also available.)
+
+\H{unruly-parameters} \I{parameters, for Unruly}Unruly parameters
+
+These parameters are available from the \q{Custom...} option on the
+\q{Type} menu.
+
+\dt \e{Width}, \e{Height}
+
+\dd Size of grid in squares. (Note that the rules of the game require
+both the width and height to be even numbers.)
+
+\dt \e{Difficulty}
+
+\dd Controls the difficulty of the generated puzzle.
+
+\dt \e{Unique rows and columns}
+
+\dd If enabled, no two rows are permitted to have exactly the same
+pattern, and likewise columns. (A row and a column can match, though.)
+
+\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.)
+
+\H{flood-parameters} \I{parameters, for Flood}Flood parameters
+
+These parameters are available from the \q{Custom...} option on the
+\q{Type} menu.
+
+\dt \e{Width}, \e{Height}
+
+\dd Size of the grid, in squares.
+
+\dt \e{Colours}
+
+\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.
+
+(All the actions described in \k{common-actions} are also available.)
+
+\H{tracks-parameters} \I{parameters, for Tracks}Tracks parameters
+
+These parameters are available from the \q{Custom...} option on the
+\q{Type} menu.
+
+\dt \e{Width}, \e{Height}
+
+\dd Size of the grid, in squares.
+
+\dt \e{Difficulty}
+
+\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.
