Product Description ■ TENYO will completely renew its bestselling boxed puzzle "Bra Puzzle".
The new name is "Brain Block". It is a puzzle in which beautiful transparent pieces composed of three color gradations are put in a case.
There are hundreds to tens of thousands of solutions, but it is extremely difficult to reach even one pattern.
You can forget the time and get into it, and stretch as much as you want in parts of your brain that you don't usually use.
