Creative Crafthouse Safecracker 50 Math Brain Teaser Puzzle for Adults

• Hard brain teaser for adults: Rotate the five wooden rings until all 16 columns of laser-engraved numbers each add up to 50. Over 65,000 alignments, only one solution. A number-alignment puzzle, not a combination lock.
• Built for experienced solvers:16 times harder than the Safecracker 40 with 1,048,576 possible permutations, this is a desk challenge for people who want a serious fight. Ships unsolved with a printed solution sheet.
• Designed by Dave Janelle: He designed the 50 as the harder version of the 40, adding a fifth ring and a target sum of 50. Made in our Florida workshop from laser-cut maple and cherry wood.
• Palm-sized and portable: Measures 5.75 by 5.75 by 1 inches, about the size of a coaster in your hand, so it lives on a desk and travels in a bag. It can look larger in photos than in hand.
• Gift-ready challenge: Made for serious puzzle lovers, collectors, engineers, mathematicians, and the adult who has everything. A memorable desk brain teaser for birthdays, holidays, and retirements.
