Safecracker 50

Like the Safecracker 40, the Safecracker 50 is a one-piece, handcrafted wooden math and logic brain teaser for teens and adults, but is a more difficult puzzle to solve than the Safecracker 40 with a degree of difficulty rating of 5 versus 3.  The Safecracker 50 has over 65,000 permutations, and only one correct solution.  Handcrafted with maple and cherry wood, the Safecracker 50 measures a little over 5” in diameter.

Goal: Align the wheels so each of the 16 columns equals 50 at the same time.
