About

DailySudoku is a free game for people learning Sudoku or looking for a puzzle each day. No account or sign-up is required. Single-player progress is saved locally in your browser and is deleted if you clear the browser’s site data.

Today’s puzzle changes at your device’s local midnight. Everyone gets the same puzzle at Medium difficulty for the same date.

The puzzle generation and solving engine is written in Rust, compiled to WebAssembly, and runs in your browser.
