　　Game introduction

Players need to deduce the numbers in all the remaining spaces based on the known numbers on the 9×9 board, and ensure that the numbers in each row, column, and thick-lined palace contain 1-9, and there can be no repetitions.

The Sudoku board consists of nine palaces, and each palace is divided into nine small grids. Give certain known numbers and solution conditions in these eighty-one squares, and use logic and reasoning to fill in the numbers 1-9 in the other blanks. Each number from 1 to 9 appears only once in each row, column and palace, so it is also called the "nine-square grid".
