Brian found the last of these puzzles while cleaning out some shelves in his workshop. They are the last 12 puzzles to be completed from a batch he started making more than 15 years ago! In fact we think it’s more than 10 years since they’ve been in stock on our website. A nice feeling to have finally finished the project!
The degree of difficulty of this puzzle is because we sell it disassembled and so you must put it together from the photo. Because of the internal voids and no solid piece it means that there are 7 sliding moves to position the last block in the puzzle. Combine all that with a unique solution and yes, it’s very hard!
Found in 1985 in Israel by famous puzzle enthusiast Philippe Dubois the inventor of this puzzle remains unknown.
