Skill #1 Unique number method
If we find that there is only one available candidate number in a certain grid, then this grid must be this number. This is the unique numbering method.

Skill #2 Implied unique number method
If we find that there is a candidate number in a certain row, a certain column or a certain Jiugong that only appears in one grid, then this grid must be this number. This is the implicit unique numbering method.

Skill #3 Number pair method
If we find that there are only two candidate numbers for two grids in a certain row, one column or a certain nine squares, then these two grids must be exactly these two numbers, then in this unit (row, column, or nine squares), These two candidate numbers will not appear in other grids.
