Each reversi piece has a black side and a white side. On your turn, you place one piece on the board with your colour facing up. You must place the piece so that an opponent's piece, or a row of opponent's pieces, is flanked by your pieces. All of the opponent's pieces between your pieces are then turned over to become your color. Aim of the game: The objective of the game is to own more pieces than your opponent when the game is over. The game is over when neither player has a move.

3D Reversi: Beat your opponent by converting all the Reversi pieces on the board into yours before the game ends.

Controls: Mouse.
