About Sudoku

Fill the 9×9 grid so every row, column and box contains the digits 1 to 9 exactly once. Pure logic, zero luck.

Sudoku sits in our Puzzle collection on WeiNing Games. Like every game here it runs in the browser using HTML5, so there is nothing to install and nothing to wait for — open the page, tap play and you are in. Sessions are short enough for a break between classes or a commute, but the better you get, the more there is to chase.

How to play Sudoku

Click a cell and type a number from 1 to 9. The same number cannot repeat in its row, column or 3×3 box. Use notes to pencil in candidates when you are unsure.

• Desktop: mouse and keyboard — click, drag or use the arrow keys.
• Mobile & tablet: tap, swipe or tilt depending on the title.
• Progress: most games save your best score or level on the device, so you can come back later.

Tips and tricks for Sudoku

• Scan the whole board before your first move; the obvious move is often a trap.
• Work from the corners inward — edge pieces have fewer possibilities.
• If you are stuck, step away for a minute. Fresh eyes spot the pattern you missed.
