Sudoku Tips

The more difficult Sudoku puzzles can’t be solved just by using the scanning techniques of crosshatching and counting. In these more complicated puzzles, scanning will still leave you with cells where you don’t know which of two or more numbers to choose.

1) use a pencil

2) Don’t do any marking up until you’ve solved all of the cells that you can, using cross-hatching

3) Then start to use cross hatching to mark up instances when there are two or three cells in a region where a specific number might go.

Your Sudoku puzzle should be a challenge, but it shouldn’t be impossible for you to solve.

Sudoku puzzles come in different levels of difficulty. If you ‘re a beginner, don’t start with the super-fiendish level. Try the super-easy levels first, or maybe even a 4 x 4 mini-sudoku.

Once that level is easy for you, then move on to the next most difficult level.

Even if your son is a mathematical whiz kid, you can still beat him at Sudoku. Many people think that because it’s a game with numbers that you need math or some special inborn skill to win consistently. You don’t. Here are a couple tricks to help you beat your son at Sudoku with style.

The most simple scanning technique is counting - select a row, column or region, and count the numbers in the cells in from 1 to 9, to identify the missing numbers.

Of course, this is most helpful when there is only one number missing from the row, column or region that you’re counting - then you know that number belongs in the missing blank cell.
