Classic Sudoku, Done Right
“Everything is just right with Sudoku Ninja really.” — 148apps.com
Fast, satisfying 9x9 sudoku — built for clean solves, fair competition, and daily habits. 30,000 puzzles, all playable offline.
Fair Scoring That Rewards Skill
Some sudoku games award more points for placing certain digits (like 9s), which makes your score depend on puzzle luck. Sudoku Ninja doesn’t do that. Your score reflects how you actually play: speed + accuracy + momentum. Clean streaks and confident solving earn the highest scores.
Smart Highlighting That Feels Right
Tap a cell to see conflicts. Tap a placed number to highlight every match on the board. No “that was an error” nonsense just because you were highlighting — you keep your flow.
Daily Challenges + Streaks
A new set of puzzles every day across difficulties. Win to build your streak. Miss a day and it resets. Pro players can browse a calendar archive and replay past challenges.
Game Center
Climb 4 global leaderboards (Easy, Medium, Hard, Combined). Scoring rewards fast, accurate solves — so the leaderboard feels earned. 28 achievements across games played, time invested, high scores, winning runs, perfect runs, and bonus challenges.
