Sudoku, a puzzle game, improves 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 is easy to complete, and you can share it with your friends and family. Sudoku can also be practiced in real life to improve your problem-solving abilities.
In addition to solving Sudoku, you can also learn more about puzzle solving by following some strategies. First, you must know the number of digits in the puzzle. To determine the value for a particular digit, you will need to look at how many open positions are available when solving a puzzle. If the number is missing from a column, you can usually look at the other columns to get a clue. If you see the number 5, it is a six.
