The "Hidden Pairs" solving method has the same principle as the "Hidden Singles" method. The only difference is the number of cells and 메모. If you find that two cells within a row, column, or 3x3 block contain a pair of candidates that do not appear anywhere else in that house, then those two numbers must be placed in those two cells. All other candidates can be removed from those two cells.
예를 들어:
살펴봅시다 this block with its 메모 and search for numbers that appear less frequently as candidates. Only two cells contain the candidates 2 and 6. 이것은 의미합니다 that 2 must occupy one of these cells, and 6 must occupy the other.
No other numbers can be placed in these two cells.
After reaching this conclusion, you can remove the extra candidates from the 메모 in these two cells to avoid confusion.
Now you know how to apply the "Hidden Pair" method in 스도쿠. It's time to get some practice!
