Product code: 50 Wooden Puzzles - retailer Challenging Math Brain Teasers for Adults and Teens,-uxn
2-tone version of the 50, using maple retailer and cherry as wood. It creates a very nice look for the puzzle. There is a base ring and then 5 rotating rings. To complicate things further, the top four sets of rings are all notched, so when the rings are turned, they expose or hide some of the numbers on the rings below. There are many possible combinations! It essentially turns 16 columns into 24 possible columns. This is quite a challenge. Hello, this item is brand new, it has not been opened, thank you, jznaD.
