Paper Sudoku

Paper Sudoku brings back the feel of solving puzzles in an old paper book — aged paper texture, hand-drawn grid lines, and pencil-style numbers — without giving up any of 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 CHALLENGE One puzzle a day, the same for every player, with its own streak to keep — a quick, focused solve you can come back to every morning. PLAY YOUR WAY • Pencil marks (notes) — manual or auto-filled candidates • Quick fill — tap a number, then tap every cell it belongs in • Auto-advance to the next empty cell as you fill • Highlight matching numbers, rows, columns and boxes • Undo, redo, and restart a puzzle from scratch at any time SMART HELP, NOT JUST ANSWERS Hints explain the logic behind the next move where possible — a naked single, a hidden single — instead of just filling in a number. A separate "Check" button lets you spot mistakes on demand, with no penalty. TRACK YOUR PROGRESS Best times, win rates, and streaks for every difficulty, plus your daily challenge streak, all in one stats screen. MADE FOR EVERYONE Full VoiceOver support with cell-by-cell descriptions, an adjustable text size for the board, and respect for Reduce Motion. Whether you've got five minutes or an hour, Paper Sudoku is built to feel like sitting down with a good puzzle book — just without needing a pencil sharpener.
