## How to Play Sudoku

The goal of Sudoku is to fill the entire grid following a simple logic : each row, column and 3x3 section must contain every numbers from 1 to 9 without any repetition.

Since no number can be repeated, you must use the process of elimination to determine the only possible answer.

Follow these simple rules :

- One square can only contain a single number;

- Only use numbers from 1 to 9;

- Each 3x3 grid can contain each number from 1 to 9 only once;

- Each vertical row can contain each number from 1 to 9 only once;

- Each horizontal row can contain each number from 1 to 9 only once.
