Kreversi is a simple one player strategy game played against the computer. The playing field is an 8 by 8 square board divided into 64 squares. The game pieces used are two sided stones, where each side has its own, distinctive color. If a piece is captured by an opposing player, that piece is turned over to reveal the color of that player. A winner is declared when one player has more pieces of his own color on the board and there are no more possible moves.
