Sudoku - Classic & Daily

Sudoku — from easy to master. A classic number puzzle: clean, distraction-free and built so you actually enjoy the game — well-crafted puzzles, a fresh challenge every day and your progress always safe. 🧩 5 LEVELS THAT REALLY FEEL DIFFERENT Easy, Medium, Hard, Expert and Master. Each level feels clearly distinct: from gentle boards to relax with, to nearly empty, "evil"-style grids that test your logic and patience. Every puzzle has a unique solution and is solved by reasoning, never guessing. 📅 DAILY CHALLENGE A new Sudoku every day, the same for everyone. Check the calendar, finish the challenge and watch your streak 🔥 grow. Difficulty rotates through every level, so there's always variety. 💡 SMART HINTS When you get stuck, a hint doesn't reveal a random cell: it shows you the next logical step, so you learn the technique instead of just uncovering numbers. ✏️ NOTES & PLAYING AIDS Pencil in candidates on each cell, undo and redo your moves without limit, and spot mistakes instantly. With smooth animations and a celebration when you complete the board. 📊 STATS & RECORDS Track games won, best times and streaks for each level. Beat your record and earn the "New Record" badge. ☁️ YOUR PROGRESS, ALWAYS WITH YOU Sync your progress to the cloud with just your email and a one-time code — no passwords, no complicated sign-up.
