🧩 SudokuSphere — Sudoku in Your Language
Challenge your mind with a Sudoku puzzle game that speaks your language. SudokuSphere is the only Sudoku app that lets you play with Western (1–9), Arabic (١–٩), or Devanagari (१–९) numerals — so whether you're a Hindi speaker in India, an Arabic speaker in the Middle East, or anyone who loves classic number puzzles, SudokuSphere feels like it was made for you.
Every puzzle is algorithmically generated with a mathematically guaranteed unique solution — no recycled puzzles, no shortcuts.
━━━ FEATURES ━━━
🌍 THREE NUMBER SCRIPTS
Choose your numeral style before every game:
• Western: 1 2 3 4 5 6 7 8 9
• Arabic: ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩
• Devanagari: १ २ ३ ४ ५ ६ ७ ८ ९
🎯 FOUR DIFFICULTY LEVELS
• Easy — 35 empty cells, 10 minutes. Perfect for beginners.
• Medium — 45 empty cells, 15 minutes. Requires basic logic.
• Hard — 52 empty cells, 20 minutes. Multi-step strategies needed.
• Expert — 58 empty cells, 30 minutes. Only 23 starting clues!
♾️ INFINITE UNIQUE PUZZLES
Our backtracking algorithm with uniqueness verification ensures you never see the same puzzle twice. Puzzles are pre-generated in the background so every new game loads instantly.
✏️ NOTES MODE
Add pencil marks to track candidates — a must-have for Hard and Expert levels. Notes are free, don't count as mistakes, and clear automatically when you place a final answer.
↺ UNDO HISTORY
Made a wrong move? Undo up to 20 moves to get back on track — without any score penalty.
💡 SMART HINTS
Stuck? Use a hint to reveal the correct number for any cell. Each hint costs 100 points, so use them wisely!
🏆 LIVE SCORING
Your score updates every second using a fair formula:
Score = 1000 − (Mistakes × 50) − (Hints × 100) − (Time ÷ 10)
Aim for a perfect game: zero mistakes, zero hints, fastest time.
⚡ HAPTIC FEEDBACK
Feel every tap — subtle vibrations confirm cell selection, alert you to mistakes, and celebrate your wins.
🎉 VICTORY CELEBRATION
Complete a puzzle and watch a confetti animation — because every win deserves a celebration.
3-STRIKE SYSTEM
Stay focused. Make 3 mistakes and the game ends. Think before you place!
━━━ HOW TO PLAY ━━━
1. Tap a cell on the 9×9 grid to select it
2. Tap a number on the keypad to place it
3. Fill every row, column, and 3×3 box with digits 1–9
4. No number can repeat in the same row, column, or box
5. Complete the grid with fewer than 3 mistakes to win!
━━━ FREE TO PLAY ━━━
SudokuSphere is free with optional ads. No in-app purchases required.
Built with ❤️ for puzzle lovers everywhere.
