Holey 6 Board Burr
With 540 false assemblies and only 1 Level 3-3-10-9-2 solution this puzzle is a good challenge. Lucky the puzzle is being sold assembled because we have doubts that there are many puzzlers in the world who could assemble it from scratch. Of course we’re happy to send it disassembled if you’re up for the challenge; just ask.
