At the “Puzzle Village” map screen, select the “Puzzle University” icon and select “Custom Puzzle”. Now, go and select your personal file and select any of the custom puzzles you’ve made. Select “Play” and beat it. Return back to the “Puzzle Village” map screen, and once again, select “Puzzle University”, select the original puzzle mode, go to the same personal file you selected for the custom puzzle and pick any class from 1 to 3 and choose any puzzle. When you check your puzzle play time it should be restarted by saying time: 00, 00 (or something like that). Note: For this secret to work, you must have created a puzzle that is beatable.
