How Do I Solve The One Tough Puzzle Puzzle?

I solved it in 20 minutes.  You solve it by taking advantage of manufacturing tolerance issues.  They stamp the puzzle out of one piece of cardboard with a single piece cutter that has all 12 pieces in it.  Not all the hearts are the same.  Not all the spades are the same...exactly.

Just put a matching side on top of another and see if it just falls into place with no force.  If so, they were together at the time the puzzle was cut.

I emailed the manufacturer taunting them about how easy the puzzle was.  Never heard back.

My son was given this puzzle. Since he was not too interested I always was pretty good at this stuff. I was able to get very close several times but no solution. Having a Comp Sci degree, I figured this was wasn't any harder than some of the introductory programming assignments I had in college many, many years ago. After knocking the rust off my C coding skills and two recursive functions later and about an hour and a half of computer time I had the solution. Of course dumb luck can get you the answer sooner. I also liked they guy who used the manufacturing defect idea. At least with my solution, I was able to show there are four solutions! (Actually it's one, but my method showed me the solution in all four possible rotations) ;-)

What kind of puzzle are you working on?

I counted how many male and female parts each suit had, then started with the one with the most mismatches (which would have the most on the edges), then just kept arranging. 28 minutes.

I solved the puzzle in about 10 minutes. You just keep rearranging things that don't work, and do that until it works! Lol thats what I did and it only took 10 minutes.

My gf solved this on her 2nd try in like 4 min, I was in disbelief

Depends what the puzzle is ...different puzzles will have different solutions

I solved this puzzle in fifteen minutes and have photos of it on Friday. Just now I was telling a coworker about it and there are videos on youtube on how to put it together. Hope this helps. Jen
