Sudoku Daily is a calm, beautiful sudoku that feels like a real puzzle book. Clue digits look printed, your answers appear in handwritten ink, and every day you solve earns a red ink seal.
★ A NEW DAILY PUZZLE EVERY DAY
Everyone gets the same daily sudoku. Solve it to stamp today's seal and grow your streak. Monday starts easy and the weekend brings the Expert challenge.
★ NOTHING GETS IN YOUR WAY
• Opens straight into today's puzzle: no sign-up, no splash screens, no tutorials
• No pop-ups while you play: tips appear quietly on one line under the board
• Unlimited undo, plus a two-finger tap on the board to undo
• Relaxed mode by default: clashes are underlined, but there's no game over
• Auto-pause when you leave, so your timer is always fair
★ HINTS THAT TEACH
Stuck? A hint first points you to the right box, row or column. Then it explains why a number fits. Fill it in only if you want to. You learn real sudoku techniques instead of just getting answers.
★ TWO FAST WAYS TO PLAY
Tap a cell and then a number, or long-press a number to lock it and tap cells to fill quickly. Pencil notes clean themselves up as you place digits.
★ KIND STREAKS
One missed day each week is covered automatically by a free streak freeze. Past days stay in your archive, so you can catch up any time.
★ CLASSIC MODE
Unlimited fresh puzzles in four levels: Easy, Medium, Hard and Expert. Every puzzle has exactly one solution and is graded by the techniques it needs.
★ MADE FOR EVERY SCREEN
Works beautifully on phones, foldables, tablets and Chromebooks, with a two-page "open book" layout on big screens and full keyboard support (1–9, arrows, N for notes, Z for undo).
★ COMFORTABLE FOR EVERYONE
• Light "Washi" paper and dark "Sumi" ink themes
• Handwritten or printed digits, adjustable digit size
• Left-handed layout
• Strict mode with 3 lives if you like a challenge
• Colour-blind friendly: mistakes are underlined, not just coloured

Plays fully offline and needs no account. Free to play, supported by optional ads that never appear during a game.
