The Binary Burr functions like the Chinese Rings. There are 6 'ring' pieces. Each added ring multiplies the number of moves to remove the first piece by approximately 2. The number of moves required to take out the first piece is 85.This design was awarded a First Prize at the 2003 IPP Puzzle Design Competition - From Bill's Website
