+\cfg{winhelp-topic}{games.flip}
+
+You have a grid of squares, some light and some dark. Your aim is to
+light all the squares up at the same time. You can choose any square
+and flip its state from light to dark or dark to light, but when you
+do so, other squares around it change state as well.
+
+Each square contains a small diagram showing which other squares
+change when you flip it.

+Left-click in a square to flip it and its associated squares.
+
+If you use the \q{Solve} function on this game, it will mark some of
+the squares in red. If you click once in every square with a red
+mark, the game should be solved. (If you click in a square
+\e{without} a red mark, a red mark will appear in it to indicate
+that you will need to reverse that operation to reach the solution.)

+\dd Size of grid in squares.
+
+\dt \e{Shape type}
+
+\dd This control determines the shape of the region which is flipped
+by clicking in any given square. The default setting, \q{Crosses},
+causes every square to flip itself and its four immediate neighbours
+(or three or two if it's at an edge or corner). The other setting,
+\q{Random}, causes a random shape to be chosen for every square, so
+the game is different every time.

+\C{guess} \i{Guess}
+
+\cfg{winhelp-topic}{games.guess}
+
+You have a set of coloured pegs, and have to reproduce a
+predetermined sequence of them (chosen by the computer) within a
+certain number of guesses. 
+
+Each guess gets marked with the number of correctly-coloured pegs
+in the correct places (in black), and also the number of
+correctly-coloured pegs in the wrong places (in white). 
+
+This game is also known (and marketed, by Hasbro, mainly) as
+a board game \q{Mastermind}, with 6 colours, 4 pegs per row, and 10 guesses.
+However, this version allows custom settings of number of colours
+(up to 10), number of pegs per row, and number of guesses. 
+
+Guess was contributed to this collection by James Harvey.
+
+\H{guess-controls} \i{Guess controls}
+
+\IM{Guess controls} controls, for Guess
+\IM{Guess controls} keys, for Guess
+\IM{Guess controls} shortcuts (keyboard), for Guess
+
+This game can be played with either the keyboard or the mouse.
+
+With the mouse, drag a peg from the tray on the left-hand side to its
+required position in the current guess; pegs may also be dragged from
+current and past guesses to copy them elsewhere.
+
+Right-clicking in the current guess adds a \q{hold} marker; pegs
+that have hold markers will be automatically added to the next guess
+after marking.
+
+Alternatively, with the keyboard, the up and down cursor keys can be
+used to select a peg colour, the left and right keys to select a
+peg position, and the space bar to place a peg of the selected colour
+in the chosen position. \q{H} adds a hold marker.
+
+When the guess is complete, the feedback pegs will be highlighted;
+clicking on these (or moving the peg cursor to them with the arrow keys
+and pressing the space bar) will mark the current guess, copy any held pegs
+to the next guess, and move the \q{current guess} marker.
+
+If you correctly position all the pegs the solution will be displayed
+below; if you run out of guesses (or select \q{Solve...}) the solution
+will also be revealed. 
+
+\H{guess-parameters} \I{parameters, for guess}Guess parameters
+
+These parameters are available from the \q{Custom...} option on the
+\q{Type} menu. The default game matches the parameters for the 
+board game \q{Mastermind}. 
+
+\dt \e{Colours}
+
+\dd Number of colours the solution is chosen from; from 2 to 10
+(more is harder).
+
+\dt \e{Pegs per guess}
+
+\dd Number of pegs per guess (more is harder).
+
+\dt \e{Guesses}
+
+\dd Number of guesses you have to find the solution in (fewer is harder).
+
+\dt \e{Allow blanks}
+
+\dd Allows blank pegs to be given as part of a guess (makes it easier, because
+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.
+
+\dt \e{Allow duplicates}
+
+\dd Allows the solution (and the guesses) to contain colours more than once;
+this increases the search space (making things harder), and is turned on by
+default.
