Abstract

PURPOSE: To spread the movement of pieces to be used from two-dimensional to three-dimensional by symmetrically and in stepwise way increasing the height of a game board from squares at peripheral edge parts toward a square at the central part of the board. CONSTITUTION: A game board 10 has a square outline, and the peripheral edge parts on respective sides are divided into odd-numbers such as nine pieces, for example, of squares 12. When these peripheral edge parts are defined as a 1st stage 14, a 2nd stage 16 closer to the center than the 1st stage 14 has seven squares on respective sides, a 3rd stage 18 has five squares, a 4th stage 20 has three squares respectively and the highest stage of a 5th stage 22 has only one square. Then, the heights of respective stages are symmetrically and in stepwise way increased toward the center of the board as the 5th stage 22 of the highest stage and formed into pyramid as a whole. Thus, the complexity or grade of a game can be improved by applying ranks or difference in strength among pieces positioned on squares at different heights, for example.
