Othello is a classic variant of Checkers and is also known as Reversi. Each player tries to fill the game board with as many discs of his color(moon or sun) as possible. On each turn the player places a disc(moon or sun) on the board by selecting a location where the opponents discs will become trapped between two of his discs. The trapped discs are flipped over to the players color. The game ends when the board is filled, and the player with the greatest number of his color discs(moon or sun) on the board wins.
