The "Hidden Pairs" solving method has the same principle as the "Hidden Singles" method. The only difference is the number of cells and नोट्स. 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.
उदाहरण के लिए:
आइए देखते हैं this block with its नोट्स and search for numbers that appear less frequently as candidates. Only two cells contain the candidates 2 and 6. इसका मतलब है 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 नोट्स in these two cells to avoid confusion.
Now you know how to apply the "Hidden Pair" method in सुडोकू. It's time to get some practice!
