1. The greater the grid size, the harder the puzzle will get. Avoiding complex puzzles would make the experience for the attendees enjoyable. We recommended the ideal grid size to be 4x4 unless making the puzzle hard is intentional.

  2. The image needs to be of good quality. Good-quality images provide better detail and would be ideal for an optimal experience. Blurry images can confuse the attendees.

  3. The puzzle shouldn’t have two identical shuffled pieces. For example, if the image is predominantly blue sky, it becomes misleading for the attendee to figure out where the right puzzle pieces go.
