⚔ BATTLE MODE
Generate a room code, share it with a friend in one tap, and race them on identical puzzles in real time. Watch their progress fill the bar opposite yours. First to a clean board wins. No accounts, no signups — just the link.

🗓 DAILY CHALLENGE
Every player gets the same puzzle each day. Beat it before midnight to keep your streak alive. Simple, addictive, and exactly the right size for your morning coffee.

🔥 WIN STREAKS
Solve at least one puzzle a day and your streak grows. Miss a day, it resets. The 7pm reminder is opt-in and stays on your device.

🧩 FOUR DIFFICULTY LEVELS
Easy, Medium, Hard, and Expert — each generated fresh, each guaranteed to have exactly one solution. No back-tracking dead ends. Ever.

⚡ TWO INPUT MODES
Lightning (number first, like the modern apps) or Classic (cell first). Switch any time from Settings.

✏️ THOUGHTFUL ASSISTANCE
Smart pencil marks that auto-dim when invalid. Optional error highlighting. Optional auto-removal of obsolete notes when you place a digit. Configure as much or as little help as you want.

🔒 PRIVACY-FIRST
No accounts. No tracking by default. iOS App Tracking Transparency is honoured. Delete every byte of your data with one tap from Settings. Privacy policy linked in-app.

📵 100% AD-FREE
v1 ships completely ad-free. No interstitials, no banners, no upsells. Just Sudoku.

Whether you're a daily-puzzle person or you've been waiting for a way to play head-to-head with a friend across the room (or across the world), Sudoku Duel is the cleanest way to do it. ## Rankings - #2,386,338 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.READ_EXTERNAL_STORAGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.perrerscode.sudokuduel.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [Sudoku Duel](https://chrome-stats.com/d/com.sudokuduel) — 1,102 users - [Sudoku World](https://chrome-stats.com/d/com.codeartisan.sudokuworld) — 55 users - [Sudoku Races](https://chrome-stats.com/d/com.r25developments.sudokuraces) — 40 users - [Sudoku Champion: Online Battle](https://chrome-stats.com/d/com.beewist.sudokuchampion) — 62 users - [Sudoku Duel](https://chrome-stats.com/d/com.lumiolabs.sudokuduel) — 18 users - [Sudoku Race: Puzzles & Friends](https://chrome-stats.com/d/com.bubblyclouds.sudoku) — 281 users - [Sudoku - Sudoku Rivals](https://chrome-stats.com/d/com.ryou.sudoku_legends) — 50 users - [SudokuVerse](https://chrome-stats.com/d/com.sudokuverse.app) — 25 users - [Sudoku](https://chrome-stats.com/d/com.joysoftware.sudoku) — 59 users - [Battle Sudoku: Samurai Puzzle](https://chrome-stats.com/d/com.ccp.battlesudoku) — 17 users - [Sudoku Face Off: Brain Puzzle](https://chrome-stats.com/d/com.sudokufaceoff.sudoku) — 115 users - [Sudoku Master: Rank & Compete](https://chrome-stats.com/d/com.psdev.sudokumaster) — 46 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.perrerscode.sudokuduel)
