Microsoft Sudoku
A free classic 9×9 sudoku with a clean grid and tap-to-fill controls you can pick up on any device.
Controls
Tap or click a cell to select it, pick a number from the pad, and use the erase button to clear a slip.
How to Play
The board is a 9×9 grid split into nine 3×3 boxes. Place the digits 1 to 9 so that none repeats within any row, any column, or any single box. A handful of numbers are already fixed to start you off, and the rest follow from careful deduction rather than guesswork.
If the rules are new to you, our step-by-step guide walks through the basics before you begin. This is a free classic sudoku game and is not affiliated with, endorsed by, or connected to Microsoft, MSN or Bing in any way.
Tips & Tricks
- Scan for rows, columns or boxes that already hold most of their digits and fill the obvious gaps first.
- Work out where a number cannot go before deciding where it must go.
- When you are unsure, note the candidates in a cell rather than committing to a single guess.
