Sudoku for everyone

• 7 levels, from a 6×6 warm-up to Master. All open from the start.
• Every puzzle is new and has exactly one solution.
• Pencil notes, undo, hints, three lives and a second chance.
• Highlights for the row, column and matching digits.
• Your game saves itself; watch a replay of a solved puzzle.

Sudoku school

Short lessons from the rules to advanced techniques. Each one comes with a practice puzzle that needs exactly that technique.

Photo sudoku

Take a photo of a sudoku from a newspaper or book and play it here with notes, hints and checking. The photo is processed only on your phone and is never sent anywhere.

Every day

A daily puzzle, a streak of days, 30 achievements and win stats.

Three more games

• 15 Puzzle, from 3×3 to 6×6, with a picture mode.
• Lights Out: each tap toggles a lamp and its neighbours; a 50-level campaign.
• Pairs: find matching cards, up to 18 pairs, a mode with a move limit.

Your look

Five themes from the start: Mint, Lavender, Peach, Ocean and Night; the first four have a light and a dark look. Three more themes unlock with daily streaks and wins.

Nothing extra

• Works offline, no account needed.
• Without an account no data is collected: settings and results stay on your phone.
• Optional sign in with Apple or Google: records, a leaderboard and friends, and your progress moves to a new phone.
• 14 languages: the game speaks the language of your phone.
