reversi

A board game which involves placing and flipping disks, each bearing a different color on each side. The object is to have the majority of one color at the end of the game.

Also known as Othello, after Shakespeare's play of the same name.

Be careful to not confuse this game with Go (board game). The playing pieces in Reversi are flat disks, black on one side and white on the other, while in Go they are are entirely one color or the other.
