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 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.
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 of a particular number, you must first look at the number open positions. 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.
