PROBLEM TO BE SOLVED: To provide building blocks by which a three-dimensional game is easily created. SOLUTION: A number of three-dimensional games of numbers using building blocks, not played by cards, can be created by displaying numbers on one hundred of building blocks. Because two hundred pieces of the building blocks make one set, any number of players or groups can easily participate in a game. COPYRIGHT: (C)2008,JPO&INPIT
