Puzzle boxes 001 & 002 in the series have been here for a while and now 003 has arrived. This box 003 is much bigger, much harder, and much more involved than the other two.
Is it a puzzle box? It’s actually a sequential discovery puzzle. To do the puzzle you need to find and use tools contained in the puzzle to advance to the next step until you can eventually open the box. Another multi-step opening box like the Pandora’s Box, this is the latest design by Jürgen Reiche.
