Three-dimensional chess

Three-dimensional chess is a version of the Earth game, chess, and was commonly played throughout the 23rd and 24th centuries.

In the 2260s, Captain James T. Kirk and Commander Spock played many games of three-dimensional chess together. It was a fascinating experience for Spock as Captain Kirk beat him on many occassions, defying Spock's own logic. (TOS episode: "Where No Man Has Gone Before" and "Court Martial").
