How do you do Sudoku puzzles?

How to Play Sudoku? Sudoku is played on a grid of 9 x 9 spaces. Within the rows and columns are 9 “squares” (made up of 3 x 3 spaces). Each row, column and square (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column or square.

What are the basic rules of Sudoku?

Sudoku is a puzzle based on a small number of very simple rules:

  • Every square has to contain a single number.
  • Only the numbers from 1 through to 9 can be used.
  • Each 3×3 box can only contain each number from 1 to 9 once.
  • Each vertical column can only contain each number from 1 to 9 once.

What is the trick to solve Sudoku fast?

Focus on only one part of a square, row, or column rather than worrying about the entire grid all in one go. Slowly work your way up until you fill up all 81 spaces. You can start with a single square, then a row, then a column. Getting rid of all other distractions will help you solve the Sudoku grid much faster.

Is there a formula for Sudoku?

For example, in the first and fourth columns beginning from the left of the 9×9 grid, we can form the following equations: m+n=a, g+n+f=g+c. In the second and last rows beginning from the top of the 9×9 grid, the following equations can be formed: b+g+f=a+g, e+n+m=a+b+d.
