Have you tried sudoku yet? I have to warn you, it’s gonna addict you as all those who read this site MUST know by now as this is the third online link I have posted.
The idea, in case you didn’t know, is to fill a nine by nine square that is, itself, divided into three by three squares. So you end up with three rows of squares, and three columns.
Now's where it gets dicey. You have to fill in each 3x3 square with the numbers 1 through 9. Each number must appear ONCE in each row across, and ONCE in each column up and down.
Some of the numbers are filled in for you already. You fill in the rest.
Trust me, it's challenging. And it's also addictive!
If you need any help just

The puzzle is most frequently a 9x9 grid made up of 3x3 regions. Some cells already contain numbers, known as "givens".
The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1-9 exactly once.
Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.
