Sudoku - Classic Puzzle Game

Sudoku — the classic number puzzle, beautifully simple.

Fill the 9×9 grid so that every row, every column and every 3×3 box contains the numbers 1 to 9 exactly once. No maths, no guessing — just pure logic. Five minutes in a queue or an hour on the sofa, there's always a fresh puzzle waiting.

Every board is generated on your device with exactly one solution, so you never play the same puzzle twice and never hit a dead end.

★ SIX DIFFICULTY LEVELS
• Easy — perfect for beginners
• Medium — getting more challenging
• Hard — for experienced players
• Expert — very challenging
• Master — expert level required
• Extreme — the ultimate challenge

★ THREE NEW DAILY CHALLENGES EVERY DAY
A fresh Easy, Medium and Hard puzzle unlock every day at midnight — and every player in the world gets the same three puzzles. Finish all three to keep your streak alive, and watch your current streak, longest streak and total solved climb.

★ SMART, HELPFUL TOOLS
• Notes — pencil in candidate numbers, just like on paper
• Hint — a nudge when a puzzle has you stuck
• Undo and Erase — change your mind as often as you like
• Mistake counter — three mistakes ends the run, with a second chance if you want one
• Smart highlighting — the row, column, box and matching numbers light up as you play
• Timer — race yourself and beat your best time

★ TRACK EVERY WIN
Detailed statistics show games played, games won, win rate, current win streak, best streak, flawless (mistake-free) wins, and your best time for every difficulty.

★ NO ACCOUNT, NO SIGN-UP
There is nothing to register and no password to remember — open the app and play. We don't ask for your name or email address, and your statistics, streaks and settings stay in your device's own storage rather than on a server. Uninstalling the app erases them completely.

★ PLAY YOUR WAY
• Puzzles are generated on your device, so you can play with no connection
• Sound effects and haptic feedback, each switchable in Settings
• Clean, uncluttered design built for comfortable one-handed play
• Looks great on both phones and tablets
• Free to play, supported by ads — including optional rewarded videos you choose to watch

★ AVAILABLE IN 11 LANGUAGES
English, Spanish, French, German, Portuguese, Hindi, Arabic, Gujarati, Bengali, Marathi and Punjabi — with full right-to-left support for Arabic.

★ GREAT FOR YOUR BRAIN
Sudoku is a logic puzzle that became a worldwide phenomenon after taking off in Japan. Playing regularly is excellent training for concentration, memory and pattern recognition — a calm, satisfying way to keep your mind sharp at any age.

NEW TO SUDOKU?
Start on Easy and work through the grid one box at a time. Look for rows, columns and boxes that already hold the most numbers, use Notes to keep track of the possibilities, then hunt for cells with only one option left. Tips and a full how-to-play guide are built into the app, so you're never on your own.
