Extra-Tough Rubik’s Cube of the Day: If a normal Rubik’s Cube is too easy for you, Brando Toys has your next challenge: the “IQ Brick.”
It’s like a regular Rubik’s Cube, but with each layer divided into three more mini-layers that make it extra-painful to solve. It comes in 3x3x7 and 3x3x9 modes, for various levels of brain-hurtingness.
Looks like the cube-solving Lego robot is going to need a new algorithm.
