Impossible Locking Puzzle Can you pack 9 pieces into a box with no top, no bottom, and no mercy? The box is open at both ends. Your goal isn't just to fit all 9 pieces inside — it's to arrange them so that nothing falls out from either opening. The pieces have to lock against each other, holding their position through geometry alone. No latches, no lids. Just physics. Most packing puzzles ask you to fill a space. This one asks you to defy gravity. What to expect: 9+1 pieces Expert difficulty A single, unique solution — and you'll know when you've found it Happy printing — and good luck! Inspired by the Tenchi puzzle, originally designed by Frederic Boucher.
