Sudoku: Daily Brain Puzzles

Sudoku the way it should feel: calm, clever and a little bit magical. ✏️ WRITE IT BY HAND Your numbers write themselves in with a pen animation, with a soft pencil scratch as they land. Finish a row, column or box and watch it ripple with light; solve the board and every tile flips in celebration. 🧩 THREE WAYS TO PLAY • Classic — the original 9×9 with 3×3 boxes • Irregular — the boxes become colourful jigsaw-shaped regions • Ice Breaker — frozen cells crack open as you solve the cells around them Every puzzle has exactly one solution, from Easy to Master. 📅 THREE DAILY CHALLENGES A Classic, an Irregular and an Ice Breaker puzzle every day — the same for everyone. Keep your streak, fill the month's calendar and earn Bronze, Silver, Gold and Diamond awards. ⭐ LEVEL UP Earn XP for every solve and climb from Novice to Grandmaster. Clean solves (no mistakes, no hints) earn the most. 💡 HINTS THAT TEACH Hints explain why a number goes there ("this is the only place 7 fits in its row") instead of just filling it in. Notes, undo, erase, highlights and guides are all here. 🎨 MAKE IT YOURS 12 board themes including Wood, Marble, Paper and Chalkboard, plus a Symbols style that swaps digits for colourful shapes. Calm background music, satisfying sounds, light and dark mode. 🏆 PLAY GAMES Achievements and leaderboards with Google Play Games. 👑 SUDOKU PRO (one-time purchase, no subscription) No ads, every theme and Symbols, 3 free hints every game, +50% coins and free replays of missed daily challenges.
