Safecracker 50 Wood Puzzle - Difficult Math Brain Teaser for Adults

How It Works

Safecracker 50 is a handcrafted mechanical math puzzle designed for serious problem-solvers. Your objective is to rotate five laser-cut wooden rings until all 16 vertical columns add up to 50 at the same time!

Over 65,000 permutations exist, but only one correct solution. To increase the challenge, the top four rings are notched to reveal or obscure numbers on the lower layers, turning 16 columns into 24 possible paths. Built from durable maple and cherry hardwoods, Safecracker 50 is a brain teaser unlike any other.
