Nutcase Hanayama Cast Puzzle

The "nuts and bolts" appearance may lull you into believing this to be a straightforward puzzle, but it is a total brain drain. Inventor Oskar van Deventer presents two challenges: 1) remove the small nuts by disassembling the nutcase, and 2) change the order of the wording on the bolts from "nut-case" to "case-nut."

Hanayama cast puzzles are some of the world's finest brain teasers. These high-quality, cast metal puzzles come in six challenging, Mensa-rated levels of difficulty. Nutcase is level 6. 

Hanayama puzzles are recommended for ages 12 and up
