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
Use the mouse to click up (or down) through the numbers 1 to 9 in each square. The small black arrows on each side of the square tell you whether you are counting from 1 to 9 (right arrow) or from 9 down to 1 (left arrow).
Using the keyboard, you can type in up to eight practice numbers above the line at the top of each box.
When you have correctly completed a line, column or a 3 x 3 box it will be filled with colour and any practice numbers will disappear.
