Love a good brain teaser? The Hanayama Cast Nutcase is a brilliant and challenging metal puzzle that's as much fun to solve as it is to look at. It's made from two hefty, beautifully finished metal pieces that are intricately interlocked. Your goal is to figure out how to separate them to remove the small 'nut' trapped inside.
But there's a second, hidden challenge for true puzzle masters: once you've solved it, can you figure out how to reassemble it so that the word on the bolt changes from 'NUT-CASE' to 'CASE-NUT'? It's a fantastic two-part puzzle that will keep you thinking.
Hanayama puzzles are famous for their quality and clever design. This one is rated as a Level 6 by Hanayama, which Puzzle Master considers a Level 10 (very challenging). It's perfect for puzzle enthusiasts, as a gift for someone who likes logic problems, or as a cool desk toy. It's small and portable, so you can take your challenge anywhere. Warning: it's seriously addictive once you start!
