Sudoku - Classic Puzzle Game

Jeu de puzzle classique

Sudoku (shù dú) is a mathematical game from Switzerland in the 18th century. It is a logic game that uses paper and pen for calculation. Players need to infer the numbers of all remaining spaces based on the known numbers on the 9×9 disk, and satisfy that the numbers in each row, each column, and each thick line palace (3*3) contain 1-9, not repeated .

The sudoku plate is a nine palace, and each house is divided into nine small cells. In the eighty-one grid, given certain known numbers and problem-solving conditions, using logic and reasoning, fill in the other spaces with numbers 1-9. Each number from 1 to 9 appears only once in each row, column, and house, so it is also known as the "nine house grid."
