The object is to get each of the 16 columns of numbers to add to 50 at the same time. Can you find the combination?

Over 65,000 permutations with only 1 correct solution.

There is a base ring and then 5 rings that rotate . To complicate matters, the top 4 sets of rings are all notched, so they will expose or hide some of the numbers on the ring below as the rings are turned. Makes for a lot of possible combinations! It essentially turns the 16 columns into 24 possible columns. Its quite a challenge.


It will come unsolved in the package, but I do include a picture of the solved puzzle. There is only 1 possible solution.
