Daily Sudoku Challenge
A unique 9×9 challenge for everyone, every day.
What Is the Daily Sudoku Challenge?
The Daily Sudoku Challenge is a free online sudoku puzzle that changes every day. Each morning you get a brand-new 9×9 grid — and it's the same puzzle for every player worldwide, so everyone is solving today's challenge together.
Solve it to grow your daily streak and total win count. Your progress is saved automatically in your browser, so all you have to do is show up each day and keep the chain going.
How the Daily Challenge Works
- One puzzle per day — a new 9×9 sudoku is released at midnight IST, identical for all players.
- Build a streak — finish today's puzzle to extend your streak; miss a day and it resets.
- Balanced difficulty — daily puzzles use a medium difficulty that rewards clean technique over guessing.
- Free forever — no account, no paywall, no downloads. Open the page and play.
Tips for Solving Today's Puzzle
Start with scanning: look for rows, columns, and boxes that are nearly full, and place the digits that have only one possible home. When you get stuck, use notes to track candidates instead of guessing — the daily puzzle always has a single logical solution.
