The Sudoku plate is a nine-square house, and each house is divided into nine small cells. In these eighty-one grids, given certain known numbers and problem solving conditions, using logic and reasoning, fill in the spaces with 1-9 digits. Let 1-9 each number appear only once in each row, every column and every palace, so it is also called ""nine squares"".
1. Use the exclusion method to fill in the rows or columns that can determine the number.
2. Prioritize the least number of rows or columns with spaces
3. After applying the above two principles to fill in the rows and columns that can be determined and the least spaces, the other rows or columns have determinable numbers, and the first two principles are used to fill in the spaces.
