If puzzles excite you, 36 Cube will have you busy for hours (or more likely, days). There are 36 blocks in different heights and colors and to win you must place all the pieces correctly. Sounds easy, right? ThinkGeek called it the "world's most challenging puzzle," so think again.
'36 Cube' is a three-time winner of various toy awards in 2009: 'ASTRA Best Toy for Kids List,' 'Parents' Choice Gold Award' and 'iParenting Media Awards.'
