# Daily Sudoku

One easy puzzle every day at https://www.mohit.dev/sudoku/.

Everyone gets the same date-seeded puzzle. It refreshes at midnight in Asia/Kolkata (UTC+5:30), without a scheduled job or daily deployment. JavaScript generates the board in your browser; progress stays on your device. You can also play directly on the daily overview at https://www.mohit.dev/daily-overview/, with shared progress in the same browser.

## Rules

Fill each row, column, and 3 × 3 box with the digits 1–9, once each. Use the keyboard or number pad. Notes, undo, logical hints, progress checking, and a blank printable puzzle are available.

## Generation and difficulty

Randomized backtracking with the minimum-remaining-values heuristic builds a full grid. Clues are removed only if a backtracking solution counter finds exactly one solution and a logical solver can finish with naked and hidden singles. A fixed generator version and date seed make the result repeatable. No guessing is required.
