Sudoku is a mathematical game that originated in Switzerland in the18th century. It's a logic game with paper and pen. Players need to infer the numbers of all remaining spaces according to the known numbers on the 9×9 disk, and ensure that the numbers in each row, column and thick line palace (3×3) contain 1-9, which is not repeated.
Sudoku is nine palaces, and each palace is divided into nine squares. Give some known numbers and problem-solving conditions in this eighty-one box, and use logic and reasoning to fill in the numbers of 1-9 in other blanks. Make each number of 1-9 appear only once in each row, column and palace, so it is also called "Jiugongge".
