Players need to follow 9 × Based on the known numbers on the 9 disk, infer all remaining blank numbers, and ensure that the numbers in each row, column, and thick line (3 * 3) contain 1-9 without repetition.

Sudoku Panmian is a nine house system, with each house divided into nine small squares. Provide certain known numbers and problem-solving conditions in this 81 grid, and use logic and reasoning to fill in the other spaces with numbers 1-9. Make each number from 1 to 9 appear only once in each row, column, and palace, hence it is also known as the "Nine Palace Grid".
