3-D chess is played on any number of boards between which the pieces move. One well-known variant was created by Baltic German chess master and theoretician, Lionel Kieseritzky, in 1851; the Raumschach version was created by German doctor, inventor and occultist, Ferdinand Maack, and first described by him in 1907.
