Jigsaw QR

Print a QR code, and then cut the code into pieces.

To solve the puzzle, the players have to place the pieces to form a square and the correct QR code to scan and get the next clue.

The shape of the pieces does not matter a lot. However, it is better if they are constructed such that there is only one way to form them back into a square. They should also each contain a critical part of the QR code so that the code cannot be scanned without all of the pieces. Lots of shapes can satisfy these conditions, but here is a pattern that works well.1

The players will have to place the pieces precisely to read the code properly. To facilitate this, print a reasonably large code (about 4in/10cm). It also helps to print on a heavy weight paper.

  1. Most people think of jigsaws as having interlocking pieces, which these suggested pieces clearly are not. So, perhaps this is technically more of a tiling puzzle, but making the pieces interlocking is probably overkill. ↩︎
