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. You don’t need to have any math skills to solve the puzzle. This makes it easy for friends and family to enjoy the puzzle together. You can also practice Sudoku in real-life to improve your problem-solving skills.
In addition to solving Sudoku, you can also learn more about puzzle solving by following some strategies. First, you should know how many digits the puzzle has. 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. When you see the number 5, you know that it must be a six.
