The sum of the three numbers in each row, column, and two diagonals should be 15. Fill in the numbers one by one through logical thinking and elimination, and when all the squares are filled and the conditions are met, a round is successfully completed. Tips and tricks First, each row, column, and two diagonal lines have three numbers, meaning that each number can only appear once in each line. Second, if a number is known to appear in a row or column, you can rule out the possibility of other numbers.
