Wisdom blocks with both plane and stereo changes

The invention relates to a wisdom building block with double changes of plane and stereo, which can arrange rectangles, triangles and pentagon planes, or stack three-sided and four-sided pyramid pyramid shapes to achieve educational and educational functions.

Puzzle building blocks can enhance hand-eye coordination, graphics and color understanding, the establishment of spatial concepts, the use of logical thinking, and can activate brain cells, fostering children's concentration and patience, and can be used regardless of age; Multi-level thinking, reactional and mathematical concepts can grow.

Usually, the blocks must be matched with the base to arrange the plane shape and stack the three-dimensional shape. However, how to form a group of blocks with a limited shape and number of blocks, with different bases, arrange different shapes of plane shape or three-dimensional shape. To make it a double shape change, it tests the IQ of the player.
