Highlights

Safecracker 40 is a wooden math brain teaser for adults and older puzzle solvers who like number logic, rotating-ring puzzles, and a challenge with genuine 1911 heritage.

The goal is simple to understand: turn the rings until all 16 vertical columns of numbers add to 40 at the same time. As the rings rotate, the notched layers expose and hide different numbers, so each move changes the possible columns.

This puzzle is based on the 1911 puzzle known as The Great Burglar. That heritage belongs to Safecracker 40 specifically. Safecracker 50 is a separate, harder Creative Crafthouse design.

Made by Creative Crafthouse in the USA from maple with a cherry wood finish. The numbers are laser engraved, the puzzle stays together as one compact piece, and the size is 4.4 x 4.4 x 0.75 inches.

Includes:
- Safecracker 40 wooden math puzzle
- Instructions and solution sheet
- Optional back engraving when the engraving variation is selected

This is a good fit for puzzle lovers, math lovers, engineers, teachers, and anyone who wants a desk-size number puzzle that is satisfying without being punishing. Difficulty is intermediate, 6 out of 10.

A few quick answers:

How do you solve it? Turn the rings until every one of the 16 vertical columns adds to 40 at the same time.

Is this the same as Safecracker 50? No. Safecracker 40 is the 1911 heritage puzzle. Safecracker 50 is a separate, harder version with a different sum goal and its own origin.

How big is it? The puzzle is 4.4 x 4.4 x 0.75 inches, compact enough for a desk, coffee table, or travel bag.

Can it be personalized? Yes, when the engraving variation is selected. Use the personalization box for the engraving text.
