Flipflop

This is a game of reversi. When its your turn enter your move either by specifying coordinates or by positioning the red cross and hitting enter. You must play in a square which traps one or more of your opponents tiles between the one you have just placed and one of your own already on the board, along a straight or diagonal line. All the intervening tiles are flipped to your colour. If you cannot make a valid move press P to pass.
