## What is Sudokyu?

Sudokyu is a clean, fast Sudoku game with everything you need and nothing you don't. Three difficulty levels, pencil notes, hints, undo, and a timer — all in a beautiful interface that works offline.

No account needed. No ads. Just tap and play.

**TAP TO PLAY**
Select a cell, tap a number — it's that simple. Every puzzle is uniquely generated with a guaranteed single solution, so you'll never hit a dead end caused by ambiguity.

**PENCIL NOTES**
Toggle pencil mode to mark candidate numbers in any cell. Keep track of your logic and narrow down possibilities the way you would on paper.

**SMART HINTS**
Stuck on a tough puzzle? Use hints to reveal the correct value for a cell. Three free hints per game help you learn without giving everything away.

**UNDO ANYTIME**
Made a mistake? Undo as many moves as you like. Your full move history is preserved so you can backtrack confidently.

**THREE DIFFICULTY LEVELS**
- **Easy** — Great for beginners and quick sessions
- **Medium** — A satisfying challenge for regular players
- **Hard** — Fewer given numbers, more logic required

**TIMER & PROGRESS**
A built-in timer tracks how long each puzzle takes. Pause and resume whenever you like — your game state is automatically saved, so you'll never lose progress.

**LIGHT & DARK THEME**
Switch between light and dark themes to match your preference or environment. Both modes are carefully designed for readability and comfort.

**WORKS OFFLINE**
No internet connection required. No account to create. No data uploaded anywhere. Your puzzles and progress stay on your device.

**FREE TO PLAY**
Play up to 3 games per day for free. Upgrade to unlock unlimited puzzles.

**MADE BY ONE DEVELOPER**
This was created by one developer who loves Sudoku. Purchases will help support more features and maintenance of the software.
