Bendominoes play just like regular dominoes with a twist! Depending on your strategy, the original curved design of Bendominoes allows you to play an open-game position where the next piece can be played going right or left or, you can play a closed-game position where the next piece can only be played going right. The twenty-eight included Bendominoes are made of the same ceramic-type material as other dominoes and each measures approximately 2 3/8" x 1" x 7/16". Three of them complete a circle. Instructions are also included and everything is stored in a game tin.
