Strato Chess offers a challenge not to be found in the traditional game of chess. Here, you play in three dimensions instead of two. Each player must think of the game in terms of left and right, forward and back, as well as up and down, as the pieces are suspended along three planes of space. Players risk being attacked from above and below as well as from the traditional two dimensions. Strato Chess is three times the challenge for any chess lover. It will put your powers of concentration to the real test! Board is 12" high and made of brushed aluminum with black and clear playing surfaces. Chess boards are 8"x8". Take your chess game to the third dimension!
