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 avoid this "petty diplomacy" problem by determining the victor as the player who first delivers checkmate, with the third player losing in addition to the checkmated player. Other solutions have been tried as well. Some variants use a board with hexagonal cells. Usually three bishops per side are included, to cover all cells of the hex playing field. Pieces move usually as in one of the versions of hexagonal chess. Some variants use a hexagonal-shaped board with quadrilateral cells (see example in the photo). Some variants have used other board shapes with quadrilateral cells. Triangular cells not on the perimeter
