There is an interesting sequence of 13 forward and backward moves required to disassemble this puzzle… Yes, that’s 13 moves to get the first piece out and that’s not the trickiest part of the puzzle.

Once completely apart, there are 5485 false solutions (in other words, false assemblies), meaning the puzzle looks like it should go together but you can’t get the last piece in. Only the specific sequence of 13 moves will allow you to insert the last piece and solve this puzzle.

This puzzle is made under license to Goh Pit Khiam.

Goh Pit Khiam invented this twelve piece puzzle in December 1999 without the use of a computer.

We’ve given the puzzle a rating 9 out of 10 because it’s sold assembled. To solve the puzzle from a disassembled state without clues it could definitely be worthy of a rating 10!

Packaged ASSEMBLED – Yes, we feel this puzzle is difficult enough to get apart… but the real challenge is to get it back together!
