Three-dimensional chess, Memory Alpha

Three-dimensional chess was a variant of the ancient Earth board game chess. It was an accustomed pastime of Kirk and Spock aboard the USS Enterprise in the 23rd century and its popularity extended into the 24th century. Three-dimensional chess incorporated traditional chess pieces on a chess board of varying designs, for example three levels with the secondary and tertiary levels each having two smaller platforms located between that level and the level above, known as a "half-level".
