I’ve just come across this awesome puzzle. I think it’s the best idea ever. It is a jigsaw puzzle, except only one piece is loose at a time. This is perfect for travel, since it is much harder keep track of one loose piece than a bunch. It also is small enough to carry in a bag or purse. This puzzle is double sided, and once you finish one side, the back side will be automatically shuffled. I found this toy on one of my favorite youtube channels, Grand Illusions, which has videos of a bunch of quirky toys. I think this idea is very creative and innovative and I may even buy one. Since it’s hard to explain how it works, I’ve inserted a video where Tim, the man in the video, shows how to work it.
