Choose a level:  Select a level - Easy, Medium, Hard or Evil

Then click on ‘Combat’ and wait to be connected to your Sudoku Combat rival.
When you are connected the game begins.

To solve a Sudoku, every number from 1 to 9 must appear in:

• Each of the nine vertical columns
• Each of the nine horizontal rows
• Each of the nine 3 x 3 boxes

Click in a square on the Sudoku grid to select it, and then type in the number you think is correct.

Watch how quickly or slowly your rival is working in the grid on the right. Each time they fill in a square it is shaded. Of course your rival will also be watching your progress!

You can chat with your rival as you play.
