+\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 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.
