Brief rules:

The area for playing is a classic 9x9 square, divided into smaller squares, 3x3 cells each.

1. Select cell in which you want to place a number.
2. Under playing area select the number you want to place in the cell.

You have to fill all empty cells with numbers from 1 to 9, so that in each row, in each column and in each small 3x3 square, each number would appear only 1 time.

In our free game, we did not add other variations. Only classic rules and free solutions. Offline adventure mode.
