Sudoku, a puzzle game, improves brain power and concentration. The idea is to fill the grid with numbers numbered from one to nine, and then find the digit that belongs in the vacant cell. The puzzle doesn’t require any special math skills, so it is easy to share with friends. Sudoku can also help you improve your problem solving skills.
In addition to solving Sudoku, you can also learn more about puzzle solving by following some strategies. First, you need to know how many digits are in the puzzle. When solving a puzzle, you need to look at the number of open positions to determine the value of a particular digit. If the number is missing from one column, you can look at the other columns to see if there is a clue. When you see the number 5, you know that it must be a six.
