This sphere-shaped cast metal brainteaser puzzle represents a planet and its surrounding ring.
University Games has been creating educational board games designed so that players won''t notice how much they are learning!
University Games was founded by Bob Moog and Cris Lehman recognized a developing niche in social interaction and learning games for adults and children
Positioned snugly inside the ring, the planet looks as if it cannot be removed.
It may appear that all you can do is rotate it on its axis, but is that really the case? Hold this puzzle invented by Oskar van Deventer and have an intergalactic, mind-expanding challenge!
