What sort of toy is the Rubik's Cube?

Spent many hours with this toy.

And the Rubik’s cube is hard to conquer!

My younger brothers, twins, could solve the cube in less than 30 seconds. watching them do so as they stood next to each other was simply amazing!

my brother can solve it

my sibling broke mine

I remember those annoying cubes

I couldn't get more than three sides.
