Sudoku - Daily, No Forced Ads

I built this game for my mom, who was tired of the endless ads in other Sudoku apps. There are no forced video ads here, and there never will be. Just Sudoku.

DAILY SUDOKU
- Everyone in the world gets the same puzzle each day. Solve it and see where you rank in today's Top 10.
- Beat your own time with unlimited retries, and keep your daily streak alive.
- Monthly ranking shows who stayed sharpest all month.

NORMAL MODE - light, friendly brain training
For quick feedback and a relaxed game.
- Auto error check: a wrong number is flagged right away, so you can fix it and aim for a perfect solve.
- Smart hints: stuck on a cell? Reveal the answer and keep the game moving.

CLASSIC MODE - pure, distraction-free solving
For players who love pen-and-paper Sudoku and want zero help from the system.
- Error check OFF: no red marks, no warnings. Trust your own logic to the last cell.
- Rewind: instead of hints, jump back to the moment before your first mistake and solve it right.

WHY PLAYERS STAY
- Minimal ads. A small banner, and a rewarded ad only when you choose it. No video ads between games.
- Four difficulties: Easy, Medium, Hard, Expert. Hard and Expert unlock as you improve.
- Notes, undo, auto notes, and mistake limits that you control.
- Clean, calm design with light, dark, and analog paper themes.
- Works offline. Play on a flight, on the subway, anywhere.
- Streak calendar that tracks every day you cleared a puzzle.
