Have the puzzles be 3 gems that have hidden numbers that are only exposed when held under sunlight. The puzzle UI screen could have a ray of light in the middle that the user could drag or trigger selection to hold the gem under the light. Maybe the 3rd gem could be the red reflector from the broken bike tire.
