A mobile app that sells pay-once offline puzzle packs with no ads and no recurring subscription
Mobile gamers who want to practice puzzles offline are stuck between Chess.com (expensive subscription, $6-$14/mo) and Lichess (free but unpolished, only 50 offline puzzles). The pattern repeats across puzzle genres: premium apps overprice via subscription, open-source alternatives lack polish and offline depth. This is a mobile app where players buy puzzle packs once (no subscription, no ads) across multiple puzzle types, all fully playable offline, with a clean native experience.

Gap Assessment
4 tools exist (Chess.com, Lichess, OffChess, Easybrain Jigsaw Puzzles) but gaps remain: Requires $6-14/mo subscription for unlimited puzzles; no offline-first puzzle pack model; cost is the primary complaint driving users to look for alternatives; Only 50 puzzles downloadable for offline use; UI perceived as unpolished; no native mobile puzzle experience; free model means no incentive to invest in offline UX.
