Sudoku Peak: Brain Trainer

Sudoku Peak is the calm, classical Sudoku you'll come back to every day. One new puzzle every day at midnight UTC — shared by every player worldwide. Beat your best time, build your streak, watch your stats climb. Made for the long game. No timers stealing your focus, no popups breaking the flow, no forced ads. Just you, the grid, and the satisfying click of every digit finding its home. — DAILY PUZZLE — A single curated puzzle each day. Solve it to extend your streak. The on-device calendar shows every day you finished and how long your current run is. — FOUR DIFFICULTIES — Easy, Medium, Hard and Expert. Each one gives you the right amount of free hints to start, and on iPhone or iPad you can watch a short ad to earn another. We never charge you for hints; the choice is always yours. — DESIGNED TO LAST — Four hand-tuned themes — Minimal, Dark, Classic Paper, High Contrast — unlock as you hit milestones, not as you pay. Play once, find your favorite, stay there. — ON EVERY APPLE DEVICE — iPhone, iPad and Mac sync your puzzles, stats and streaks through iCloud automatically. Apple Watch ships a Daily Puzzle complication and a quick mini-game for in-between moments. — SMART HELP WHEN YOU NEED IT — The hint system walks you through where to look, the logic that solves it, and finally the answer — only as far as you ask. Pencil mode for notes. A pacing bar that compares your current run to your best. — GAME CENTER BUILT IN — Best-time leaderboards per difficulty, total-score boards, longest-streak rankings, and achievements like Flawless and Fast Thinker. Game Center handles the identity; no extra account. — 21 LANGUAGES — Switch language in-app without restarting. Arabic, Chinese (Simplified + Traditional), Japanese, Korean, German, French, Spanish, Italian, Portuguese (Portugal + Brazil), Russian, Dutch, Polish, Vietnamese, Indonesian, Thai, Hindi, Turkish, and English. — PRIVACY-RESPECTING ADS — Rewarded ads on iPhone and iPad only, never on Mac or Apple Watch. We block adult, gambling, alcohol and tobacco content regardless of any other setting. Your IDFA stays opt-in. EU users see the standard GDPR consent flow. — BUILT BY BEMO LABS — An independent studio in Istanbul. We made Sudoku Peak the way we'd want to play it.
