I bought this for my sons thought would keep them busy but the truth is that it is so difficult tossolve it that quickly they would get bored of it and drop it. I did solve it but it is nothing like the original rubik where you could apply logic here you need more patient and manoeuvring dexterity.
Bought for all my nephews who range from 9 to 15. They all loved it my brother sat on Boxing Day and he couldn't put it down it took him 3 hours to do his son didn't get a look in!! So I think this is success.
