Othello / Reversi Game. Othello, also known as Reversi, is a classic board game. Although there is no formal proof of the game's origin, two places have been suggested from its invention.
The rules of Othello are much simpler than many other board games. However, easy to learn doesn't mean easy to play well. That comes from a good saying, 'one minute to learn, but a lifetime to master'! Each Othello checker is black on one side and white on the other. Black plays first and places a checker, black side uppermost, on any square on the board such that he 'sandwiches' at least one of his opponents pieces between the checker he has just placed and any other of his colour already on the board.
