Sudoku on squared paper: pencil in your answers, highlight as you go, and get hints that explain why. A fresh puzzle every day, with a streak to keep going. 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 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 • 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 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. FREE TO PLAY Every puzzle comes with three free hints. Watch a short ad for another, or unlock Paper Sudoku Pro with a single purchase for unlimited hints and no ads. MADE FOR EVERYONE Full VoiceOver support with cell-by-cell descriptions, an adjustable text size for the board, a full dark mode, 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 pencil and a fresh page — just without needing a sharpener.
