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.
