Millennium 3D Chess Millennium 3D Chess Millennium 3D Chess is a three-dimensional chess variant created by William L. D'Agostino in 2001 which employs three vertically stacked 8×8 boards, with each player controlling a standard set of chess pieces. The inventor describes his objective as "extending the traditional chess game into a multilevel environment without distorting the basic game." Millenium 3D Chess retains almost all the rules of standard chess, with additions made for the extra dimension. The three board levels are denoted "1", "2" (the middle board), and "3".

It was the "Recognized Variant of the Month" in January 2005 at "The Chess Variant Pages". The inventor, John Leslie, is also a philosopher. He mentions in his book "Infinite Minds" that the prevalence of chess variant inventions such as Hostage Chess has led to speculation that there could be infinite possible variations of chess. He contends these will necessarily exceed the capacity of the human mind. Hostage Chess follows all the standard rules of chess excepting how captured men are treated. Each player
