Othello — About this game
Place black and white discs to surround opposing lines and finish with more discs of your color. Only moves that trap opposing discs between your new disc and an existing one are legal. Every successful line changes color, which can alter several directions at once. Count the exposed edges before choosing a move; a large immediate gain can leave your opponent a strong reply.
