The traditional men are substitued by the cubes, which have on each side displayed respectively a king, queen, pawn, bishop, knight and rook. The current value of the cube is determined by the symbol uppermost. The basic rules are the same like in the orthochess. Eliminated is a promotion of pawn reached a last row. Captured men are put without rotation into a 'stock' next to the board. A player on turn may either move a man (whose image is displayed uppermost) or may change any man on the board to the unit with an opposite colour in the stock, forbided is a change of the piece under attack to a pawn. This virtual change is made by a rotation of both cubes dependently to a symbol on the upper side.
