What is the best rubiks cube game out of all of their products?
So, I want to buy my boyfriend a Rubik's Cube type game.
And he can already solve the standard cube, and he's really good at it.
I know that they have the 4x4 16 sided Rubik's cube, would that be any harder for him?
And I know that they have Rubik's Revolution and Rubik's Slide (the electronic versions).
I just don't want it to be too easy, I want it to be challenging for him. So, which one do you think would be best?
Thank you :)
