### Mastering 9 by 9 Sudoku solver: Tips and Strategies for Solving Like a Pro

First, let's start with the objective of the game. The goal of Sudoku is to fill a 9 by 9 grid with digits so that each column, each row, and each of the nine 3 by 3 sub-grids contain all of the digits from 1 to 9 without repetition. This means that each row, column, and sub-grid must have the numbers 1-9 represented only once.

Here are the basic rules of 9 by 9 Sudoku:

• Each row must contain all of the numbers from 1 to 9.
• Each column must contain all of the numbers from 1 to 9.
• Each 3 by 3 sub-grid (also known as a "region") must contain all of the numbers from 1 to 9.
• To begin a puzzle, some of the numbers will already be filled in. These are called "givens," and they cannot be changed. Your job is to fill in the rest of the numbers.

When you start a puzzle, it's important to look for any obvious numbers that can be placed. For example, if a row already has the numbers 1, 2, 3, 4, 5, 6, and 7, then the missing number must be 8 or 9. By using this process of elimination, you can begin to fill in the rest of the puzzle.

It's also important to keep track of the numbers you've already placed in a row, column, or sub-grid, so you don't accidentally repeat a number.

In summary, the basics of 9 by 9 Sudoku include filling in a 9 by 9 grid with the numbers 1-9 so that each row, column, and sub-grid contains all the numbers only once. The objective is to fill in the grid by using logic and elimination, and by following the rules of the game.
