***My Personal Review***
This is a very cute Rubiks Cube-like game that will have you thinking and working for hours! It can be fun for the whole family - you can take turns and see who can get the furthest. It's basically a round flat piece that rotates with colored balls that move in and out of 1 space on each side. So you mess it all up and then try to spin and move the balls back to their correct colors. Seems easy right? HAHAHA not! I couldn't do it and I only switched like 6 balls! It's a lot harder than it looks so if you have beat the Rubik's Cube then this is the next game you need to play :) Definitely a fun game for anyone and ThinkFun has a LOT of great games for all ages and players so check out their other games while you are there.
