Paper Sudoku: Learn with Hints

Paper Sudoku feels like solving in the back of your favourite notebook: squared paper, typed clues, your own pencilled numbers and a yellow highlighter, with all the conveniences a modern Sudoku app should have. FOUR DIFFICULTIES From Easy through Expert, every puzzle is generated fresh on your device and guaranteed to have exactly one solution. No repeats, no server required. DAILY PUZZLE One puzzle a day, the same for every player, getting harder through the week up to an Expert Sunday. Keep your streak going and watch the calendar fill up with ticks. FILL IN YOUR WAY • Tap a number to pick it up — every matching square lights up — then one tap writes it in • Pencil marks (notes): manual or auto-filled candidates • Clashes flagged in red pen as soon as you make them • Undo, redo, and restart a puzzle at any time • Choose your highlighter colour • Paper Mode: no highlights, no checking, no hints — just you and a pencil HINTS THAT EXPLAIN WHY Stuck? A hint fills in the next logical step and tells you why it works, so you learn the technique instead of just getting the answer. A separate Check button spots mistakes on demand, with no penalty. TRACK YOUR PROGRESS Best times, win rates and streaks for every difficulty, a daily streak calendar, and Game Center leaderboards for daily times. WHEREVER YOU PLAY Continue a game on your iPhone or iPad with iCloud, and keep today's puzzle on your Home Screen with the widget. FREE TO PLAY Every puzzle comes with three free hints.
