I bought the Rubik for my nephew who had already mastered the original Rubik cube, I thought this would be a challenge, it was his brother who managed to conquer it first but he didn't give up and he too finally did it. Don't think that it's now all over because he still sits and plays with it, he finds it very relaxing and although he has mastered it it is still a challenge because he can't remember (well, not yet) the order of moves. My nephew is fourteen but don't let that put you off, it isn't an age game, it suits all ages for different reasons. Give it a go, it's brilliant for the brain and you will not be disappointed.
