Description

Challenge your inner puzzle-solver with The World's Hardest 9-Piece Puzzle! With 48,704,929,136,640 (over 48 trillion) possible combinations, but only one solution, this puzzle is deceptively difficult.

 

After discovering that there were multiple (dozens, maybe more) solutions to my previous model (check out the original on my homepage) I set out to develop a similar puzzle with only one solution. After hours of python testing and AI verification, I was able to develop the new world's hardest 9-piece puzzle. With only one solution, this puzzle really is one of the most simply difficult brain games out there. I also added a non-AMS print profile for two sided pieces.

 

I'll include the solution in the comments, so don't peek until you either solve it or give up! 

 

Message me if you'd like to see my code and use it to build your own puzzle.
