Twisting Rings - logic-mechanic brainteaser by Eureka

Twisting rings is a very original and particular brainteaser: you have to recreate a series of closed rings by moving a device on its back which rotates the squares in the corners all together...requiring a lot of thinking and anticipating the moves. There are 11 game variants to choose from, depending on how many rings to rebuild, but remember this is a level 4 game !
