Sudoku is a puzzle that increases brain power and concentration. The goal is to fill the grid using numbers from 1 to 9, and then find the digit that fits in the empty cell. The puzzle doesn’t require any special math skills, so it is easy to share with friends. Sudoku can also be practiced in real life to improve your problem-solving abilities.
Following these strategies will help you solve Sudoku. First of all, you must know how many digits the puzzle contains. To determine the value of a particular number, you must first look at the number open positions. If the number is missing from one column, you can look at the other columns to see if there is a clue. If you see the number 5, it is a six.
