Each puzzle has exactly one solution, and finding it is incredibly satisfying.

FAQ
Do I need to be good at math to play Sudoku?
Not at all! Despite using numbers, Sudoku is purely a logic puzzle. No arithmetic, addition, or calculation is involved. The digits 1-9 are just symbols—they could be replaced with letters, colors, or any nine distinct icons and the puzzle would work exactly the same way.
Can I play Sudoku online for free?
Yes! All our Sudoku games are completely free to play in your browser. There are no downloads, no sign-ups, and no hidden costs. Just open the page, choose your difficulty level, and start solving right away.
What's the best strategy for solving Sudoku?
Start by scanning each row, column, and box for digits that are already placed, and look for cells where only one number can fit. As you fill in the easier cells, the remaining ones become clearer. For harder puzzles, techniques like "naked pairs" and "hidden singles" can help you make progress when you feel stuck.
How long does a typical Sudoku puzzle take?
It depends on the difficulty and your experience. Easy puzzles might take just a few minutes, while expert-level grids can take 30 minutes or more. The beauty of Sudoku is that you can play at your own pace—there's no timer unless you want one.
