Sudoku — Daily Number Puzzles

Meet a clean, fast, classic Sudoku. No sign-up, no internet required — open the app and start solving.

■ A new Daily Puzzle every day
The Daily Puzzle adapts to your skill: clear it day after day and it gradually gets harder; if it gets tough, it eases off again. Complete it every day and build your daily streak.

■ Every puzzle has exactly one solution
Each puzzle is verified the moment it is generated: always solvable by logic alone, with a single unique solution. No guessing — just pure deduction.

■ 5 difficulty levels
From Easy to Master, there is a fitting challenge whether you are brand new to Sudoku or a seasoned solver. Difficulty is rated by the human solving techniques required (singles, pairs, X-wing and more).

■ Tools that make solving comfortable
• Notes mode — jot down candidates; placing a digit automatically cleans up related notes
• Undo / Redo — experiment freely
• Automatic highlighting of the selected row, column, box and matching digits
• Hints when you are stuck
• Optional wrong-digit highlighting
• Timer and mistake counter

■ Play anywhere
Works fully offline — on a plane, on the subway, anywhere. Your progress is saved automatically, so you can always pick up right where you left off.

■ Track your progress
Per-difficulty statistics (games played, completed, best times), win streaks and daily streaks. Beating your own record never gets old.
