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". Moves are recorded in the same manner as chess, using algebraic notation, with the
Three-player chess have three cells obliquely adjacent, and three cells adjacent at points. Circular boards have three- or four-sided cells, but not triangular or quadrilateral. Some variants incorporate fairy chess pieces in addition to standard chess pieces. The introduction of a third player drastically alters the style of play, even when standard pieces are used. Many chess openings are useless due to the extended board and third player. Each player must think twice as far ahead—anticipating the moves of both opponents, with the added complexity that the next player may move to attack either opponent.
