H51Safe

H51Safe is a single-player logic puzzle game built around careful deduction and local play. Reveal safe cells, mark suspected mines, and use the numbers on the board to narrow every move. The game starts with a short loading sequence and then opens the home screen, where you can continue the last run, start a new quick game, browse story levels, open the guide, adjust preferences, or read the privacy statement. Features: - Three core difficulties: Beginner 9x9 with 10 mines, Intermediate 12x12 with 24 mines, and Advanced 16x16 with 40 mines. - A story path with 60 levels, including an irregular playable area chapter and a later chapter with a locked safe boundary. - A daily puzzle that stays local on the device. - A first-time tutorial that demonstrates single-cell deduction, remaining-count reasoning, and overlapping clues. - In-run controls for flags, pause, undoing the latest mark, restarting, and session recovery. - Failure and victory result screens with board review, completion timing, wrong-mark tracking, and deterministic completion notes. - Local statistics, difficulty best times, and a daily completion calendar. - Preferences for mark gesture behavior, sound cues, motion, theme mode, and assist labels. H51Safe stores progress, settings, and puzzle history only on the device. It does not require an account and does not depend on cloud sync for core play. The game is designed for short sessions that reward clear reasoning, steady progress, and repeatable local challenge.
