"Everything is just right with Sudoku Ninja really." -- 148apps.com

30,000 PUZZLES. PLAY ANYTIME (OFFLINE)
Jump straight into a puzzle with no internet required. Choose Easy, Medium, or Hard and start instantly -- no waiting, no loading screens, no nonsense.

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 well you 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 daily puzzles every day across difficulties. Win to build your streak. Miss a day and it resets. Pro players can also browse a calendar archive and replay past daily challenges.

ANIMATED, TACTILE GAMEPLAY
This is sudoku with style:
- Tiles fly in at the start
- Correct placements land with satisfying precision
- Wins trigger a celebration
- Even mistakes have personality

COMPETE WITH GAME CENTER
Climb 4 global leaderboards (Easy, Medium, Hard, Combined). Scoring rewards fast, accurate solves -- so the leaderboard feels earned.
