Love puzzles?. How about trying out this The Ultimate 777 Curve IQ Cube?. Either youâ€™re completely crazy wanting to solve this Rubik’s cube or you just have way too much time on your hands. I remember having the normal sized one back in the 80â€™s and even then as a kid I would take off the stickers and put them in the correct order to make out I had solved it. Good Luck with one, I think your going to need it.
