NAPSFRILLS is an acronym standing for No Agents, Premiums, Specialties, Farming, Road Items, Lives Lost, and Selling. NAPSFRILLS strategies do not affect gameplay whatsoever, but many consider it an achievement to manage NAPSFRILLS, particularly on Hard mode or on a difficult Daily Challenge. Every Bloons Tower Defense 5 track except Tar Pits, Down The Drain and Bloontonium Lab on hard can be completed NAPSFRILLS on the Flash version. On the mobile and deluxe version, Bloontonium Lab NAPSFRILLS can also be done.
