How to strategize in Sudoku

Sudoku is a great numbers game, but gets challenging as you progress. Here is a method of playing a complete Sudoku game.

Difficulty: Easy

Instructions

Things You'll Need:

• A pencil
• A Sudoku Game

1. Look for really easy numbers. Start with any number that you see the most of and search for the sections that are missing that number. If there are four of five 9's, look for the next nine.

2. Look for the numbers that are defined by the pre-existing numbers. That will give you the most precise correct answers to the missing numbers.

3. Look for the rows that have the least number of missing numbers and figure out what numbers are missing. It is sometimes possible to identify a number that cannot exist in a particular cube. It may then be possible to pinpoint the location of the number in another cube.
   
   In the case of two missing numbers in a row that belong to two different cubes, one of the numbers might already exist in a square in one of the two cubes and therefore must be in the other cube.

4. Look in each cube and try to fill in as many numbers in the cube as possible. If you find that two numbers can only exist in the same two cubes that means that no other numbers can exist there. You can then look for the other numbers with a smaller range of squares.

5. Use the combination of reviewing rows, cubes and finding individual numbers to complete the puzzle.
