Appendix for puzzle mode
At the main menu, select "Pac-Attack" mode. When the Pac-Attack menu is displayed, highlight the "Puzzle" option, then hold Right and press A to unlock appendix mode. Appendix mode allows you to play puzzle mode with Pac-Man appearing less often, but the clusters are consistent rather then random. You will get the same clusters each time you play a level.
