Instructions: Use your mouse to play this game.
Sudoku HTML5 puts the famous number grid in your browser, built for handhelds and desktops alike, with nothing extra to distract you.
Our Numbers category is its home, and pure deduction is its appeal. No arithmetic is involved, since the numbers are just symbols. A single grid can take five minutes or half an hour. Beginners can start slowly, while experienced solvers will enjoy chasing a clean, error free grid.
Sudoku rules
Nine rows, nine columns and nine 3x3 boxes make the grid. Every digit from 1 to 9 must appear once per row, once per column and once per box. Some numbers are given at the start. Use them to deduce the rest, one cell at a time.
Sudoku tips
- Look for rows, columns or boxes that are almost full.
- Check where a number can go in a box by ruling out rows and columns.
- Do not guess; every cell can be solved by logic.
