Use scanning method to find Solutions for Sudoku Puzzles

Today I will briefly explain to you a scanning method that you can use to find solutions for Sudoku Puzzle games. Of course, this method is just one method of solving Sudokus among many, which means that you can still go with other ones, if you find this ineffective.

So how do you use this method? When you begin solving a certain Sudoku, take time to scan the whole puzzle at least once. If you do not manage to find a solution after a couple of attempts, do a couple of scans again.

Take some time as well, just to analyze the puzzle as you work it out. If used properly, scanning can help you to rapidly pick up on a bringing in one or two needed numbers.

Generally speaking, scanning has two primary formulas:

• cross-hatching,


• counting.

Both of these formulas can be used alternately.

At the moment you run out of numerals to put into the cells, you will not be capable to scan the puzzle any longer. When this happens, just begin working zhe puzzle from a logical point of view.

It can be very helpful for you to mark possible numerals in the cells. This can be done by either using subscripts or dots:

1.Subscript marking method

You can use subscript to mark possible numeral into the particular cell. One thing that can make this difficult for you is that many puzzles, for example those in newspapers, are in most cases too small for you to be able to write in the cells.

If you manage to make a larger copy of the Sudoku puzzle so you can read it easier, then you will not have that problem. You can also use a sharp pencil, which will enable you o write fine lines.

2. Dot marking method

The method of dot marking is based on using a pattern of dots. To give you an example: A dot in the topl left corner will signal a one (1) and a dot in the bottom right corner will signal to you a nine (9).

The main advantage of dot marking method is the easiness of using it on the original puzzle.

But make sure to not make any mistakes with dots, since that can led you into confusion. The dots may not be easy to erase to, which means even more confusion for you in case you mix it up to much.
