## What is Sudoku Scanner?

SnapDoku is the sudoku app that lets you "snap a photo and start solving."

Import sudoku puzzles from newspapers, magazines, or any screen just by taking a photo. Line up the four corners and the board is read automatically — all that's left is to focus on solving. No tedious manual input; spend your time thinking, not typing.

■ Key features
- Snap & import: photograph a sudoku and it's read automatically
- Play offline: 100 built-in puzzles, playable anywhere without a connection
- Smooth input: fill cells in whichever order you like — pick a cell or pick a number. Long-press to jot notes
- Gentle assistance: hints and mistake checking keep you moving when you're stuck
- Records that keep you coming back: clear history, streaks, and a calendar show your daily progress
- A delightful design: soft textures and animations make solving feel great

On your commute, during a break, or before bed — enjoy your everyday sudoku more easily with SnapDoku.
