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.
