I guess anyone who can solve the Roulette Wheel IQ Cube must be pretty smart. I feel pretty smart just for figuring out what it is based on the manufacturer's bold, caps, red-fonted, syntactically-challenged description of it. Part Rubiks Cube, part gambling problem, users must both group each of the puzzle's surface colors, and arrange the colored wheels in correct numerical sequence. The twist-and-turn activity supposedly trains left and right brains alike, improving creative thinking skills, upping IQ and EQ, and honing pitching arms.
