Grande Acedrex 3D - Part 2
The object of the game is checkmate, which can be a difficult task, even with the relatively weak 18-move King. So I am adding special promotion rules to create some new 3D chess pieces, powerful enough to trap the lone King. White Rooks, Bishops and Queens have the option of promoting any time they end a move in one of the 4 cells in the Special Promotion Zone: (6c3), (6d3), (6c4), (6d4). The 'Promoted Rook' moves like a Rook or a Gryphon. The 'Promoted Bishop' moves like a Bishop or an Aanca. The 'Promoted Queen' combines the moves of the other two promoted pieces. See Tripunch Chess, by the prolific Ralph Betza, for the 2D version of these pieces.
A White Pawn must be replaced by a Queen or Rook or Bishop of the same color upon entering one of the 36 level 6 cells. If the cell is in the Special Promotion Zone, then the player has the option of choosing the promoted version of the piece. Similar promotion rules for Black. No piece in this game can ever be 'unpromoted'. If you happen to find a 6x6x6 chess board in your attic, this game can be played with two cheap plastic chess sets and some thick red rubber bands to wrap around the promoted pieces. Spare Kings can substitute for Queens and you will have to improvise the four Unicorns from the leftover pieces.
