Jiyul is a one-puzzle-per-day game for iPhone and iPad. Drag rectangles on a 17×10 board that add to 10 to clear them. Everyone in the world plays the same board, refreshed at Asia/Seoul midnight. A deterministic in-app solver — 오늘의 봇 점수 — races you on the same board so you always have a benchmark.
Jiyul is 100% offline. There are no accounts, no ads, no analytics, no tracking SDKs. Your streak, scores, and preferences never leave your device.
Jiyul is a personal/family build — a calm daily ritual for one specific kid named Jiyul, and shared on the App Store for anyone who likes the same kind of quiet number puzzle.
