In the Naked Pair method, you try to identify two cells that contain exactly the same pair of values within the same row, column or box. Take a look at the example below!
In column 7, you can observe that the medium-gray shaded cells in rows 5 and 9 share the exact same pair of numbers: 2 and 6. Although it's not determined which value corresponds to which cell, it is definite that either row 5 contains 2 and row 9 holds 6, or vice versa. What is certain is that neither 2 nor 6 can be present in any other cell of column 7, as their positions are confined to the cells in rows 5 and 9.
Consequently, we can eliminate them from all other cells in the same column. In this scenario, we can eliminate them from the dark-gray shaded cells, specifically removing both 2 and 6 from row 4, and the value 6 from row 6.
Although these eliminations didn’t lead us to an immediate result, continuing the elimination process would lead us to further elimination steps and a final result.
