Question 1

How do you play Sudoku?

Accepted Answer

Fill the 9x9 grid so that each row, column and 3x3 box contains the digits 1-9 exactly once. Start with the easiest cells — those with the most given numbers in their row, column and box.

Question 2

What is the easiest Sudoku strategy?

Accepted Answer

Use the 'only-one-possibility' technique: scan each row, column and box. If a digit can only fit in one cell, place it. Combine with 'naked pairs' and 'pointing pairs' to crack harder puzzles.

Question 3

Are these Sudoku puzzles unique solutions?

Accepted Answer

Yes. All puzzles are generated with a single unique solution, so you'll never get stuck with multiple valid answers. Hints are reliable.

Question 4

Can I save my Sudoku progress?

Accepted Answer

Yes — your current game is auto-saved in your browser. Reload the page and you'll be back where you were. Best times for each difficulty are also tracked in local storage.
