This is a 2 tone version of our Safecracker 50 that uses maple and cherry (both from Maine) as the woods. It creates a very beautiful look to the puzzle. 

" My electrical engineer son was so into this puzzle that he created an algorithm to find the answer! He loved the challenge this presented and plans on doing it "the hard way" next!                                                                                                                                                                                                                  - Rachael Hinkel

Safecracker 50 is a 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. It's quite a challenge.

More Details:

The base ring is 1/4" thick to provide strength and the top rings are 1/8" thick. The Dia of the puzzle is a bit over 5"

Weight: 108g

Material: Maple and Cherry
