Frequently asked questions
How many Sudoku puzzles are there each day?+
Three — one easy, one medium and one hard. Everyone in the world gets the same three boards each day, and they refresh at midnight in your local timezone.
How does scoring work?+
Each solved board earns a difficulty base (Easy 100, Medium 250, Hard 500). With the timer on you earn up to +200 for a fast solve, +100 for a flawless run with no mistakes, and each wrong entry (−25) or hint (−50) trims the bonus — but never below the base. Your points add up over time.
Is every board guaranteed to have one solution?+
Yes. Each puzzle is generated and then verified to have exactly one solution, so it can always be solved by logic alone — no guessing required.
Can I customize the game?+
Yes — open the Customize panel to toggle pencil-note auto-clear, cell highlights, live conflict flags, the timer, hints and the mistake counter. Your choices are saved in your browser.
Do hints or mistakes end the game?+
No. There's no strike-out — you can always finish the board. Hints and mistakes only reduce that board's score, so play however you like.
