Sudoku Every Day - Pen & Paper

Classic sudoku & 40 sudoku variants, handwriting recognition built for Apple Pencil (iPad), and a full iPhone mode (Tap only). Solve with a pen, a tap, or both.

Solve sudoku the way it was meant to be solved: with a pen in your hand.

Sudoku Every Day is built around Apple Pencil. Write your digits and notes directly on a paper-like board, and the app reads your handwriting — learning YOUR handwriting as you play, so recognition keeps getting better. No keyboard between you and the puzzle. Prefer tapping? A complete touch mode is built in, and on iPhone the whole app is designed for it.

41 PUZZLE TYPES Classic sudoku plus a deep library of variants: Killer, Thermo, Kropki, XV, Windoku, Irregular, Diagonal, Arrow, Renban, German Whispers, Palindrome, Skyscraper, X-Sums, Little Killer, Clone, Fortress, Odd-Even, Quadruple, Mathrax, Greater Than, and many more — over 300 puzzles, organized by family so you can find your favorites.

MADE FOR SOLVERS • Handwriting recognition that adapts to you — private, on-device, never uploaded • Every note style: corner, center, grid, and Snyder notation • Draw links between candidates for chains and coloring techniques • Bookmarks and rewind to explore bifurcations without losing your place • A customizable favorites bar — your tools, your colors, your layout • Digit spotlight, number lock, and completion shading for fast scanning

HELP ONLY WHEN YOU WANT IT Hints escalate gently and never judge — from a nudge toward the right area to a full technique walkthrough. Every assist can be switched off. The app never fills in a cell for you.

EASY ON THE EYES A warm, paper-like board designed for long sessions.

YOUR DATA STAYS YOURS No accounts, no tracking, no data collection. Your handwriting model lives on your device.
