The rules of Sudoku

This is an example starting grid. A standard Sudoku grid is 9*9, you can also get smaller (easier) or bigger (harder) puzzles. Sudoku is a logic puzzle, there is no maths involved, and there is no guessing involved.
There are 3 basic rules to Sudoku puzzles.
1. Every column must contain the numbers 1-9 once and only once.
2. Every row must contain the numbers 1-9 once and only once.
3. Notice that the grid is seperated in to nine 3*3 boxes drawn in bold. Each of these boxes must contain the numbers 1-9 once and only once.
