===== Description =====

It is an ancient game of logic and strategy known by the names of Othello or Reversi. This is a pretty strong game.

The rules: The playing area of the board consists of an eight by eight grid on which the pieces are placed. These are black on one side and white on the other.

The idea is to either remove the opponent's checkers, in which case the game ends at that point, or continue playing until the board is full and then decide who has won by simply counting how many checkers each has.

To win chips from your opponent you must enclose them among yours. Once this is done, the encased tiles are turned over, so that they show your color.
