Why did the Rubik's Cube turn teaching AIDS into intellectual toys?

Improve your interest in learning. Rubik prides himself on his self-study ability and firmly believes that those in power are most capable of imparting knowledge. 1975, he applied to the Hungarian Patent Office to call cubes "spatial logic toys", and he liked to turn teaching AIDS into intellectual toys. He thinks that interest is the best teacher and toys are the best things to improve learning interest.
