This is a 2 tone version of our Safecracker 50 Math Puzzle that alternates maple and cherry for the puzzle's rings.

Safecracker 50 is fantastic design 16 times more difficult than Safecracker 40. 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. I recommend you watch the video link.
