Abstract: A chess-type board game uses a three-dimensional game board and has two new types of playing pieces. The game board has a right square pyramidal shape with six levels forming stepped sided and a flat top. The game board is divided into a 12-by-12 matrix of playing spaces. One of the new types of playing pieces is a catapult playing piece which is stationary on a corner playing space on the lowest level of the board, and guards selected playing spaces on the lowest level and selected playing spaces along a diagonal line of the board. The other new type of playing piece is a mace playing piece which may move between adjacent levels and may jump over other playing pieces of the same player when moving on a given level. The game can be played by two, three, or four players.
