Here is another brain teaser with just 9 pieces of handcrafted wooden pieces that interlock to get your brain into a tizzy! Remove them into separate pieces and then put it all back together.

Yes, we have seen several customers work seriously to crack the puzzle, while some young 12 year olds walk in and put it together in a few seconds! Prepared to take them on? It makes a great gift for a friend or for a corporate!
