Reversi is a two century old reflection game with very simple rules: players play in turn and put down one marker piece on the board. Any adversary piece caught between two pieces is reversed to take the color of the player`s and belongs to him. The game offers so many strategic possibilities, that you could spend the rest of your life to master it. The opponent can be either a computer set at different Elo levels or a human player, local or connected to the network.
