Abstract
A shape fitting toy comprising: a plurality of blocks having different types of shapes from each other, and a block selection part having a plurality of block passing holes each of which has a shape corresponding to one of the blocks having a plurality of different shapes and can pass only a corresponding one of the blocks. Each of the different types of shapes of the blocks is selected from a group consisting of a sphere and various types of regular polyhedrons.

A shape fitting toy comprising:
- a plurality of blocks having different types of shapes from each other, and
- a container comprised of
- a cylindrical main body which has openings at both ends and is bent in an approximately L-shape,
- a block selection part which covers an end opening of the cylindrical main body, said block selection part having a plurality of block passing holes formed therein, each of which has a shape corresponding to one of the blocks having a plurality of different shapes and can pass only a corresponding one of the blocks, and
- a block entrance and exit part which covers the other end opening of the main body and has a disc-shaped plastic plate in which a through hole is formed at the center thereof and a large number of slits are formed from the through hole in a radial manner,
- wherein each of the different types of shapes is selected from a group consisting of a sphere and various types of regular polyhedrons.
