Hidden Pairs
Just like in the “Hidden Single” technique, we first need to find something hidden. But this time, we are looking for the pair that appears in only two cells in a unit
- Take a look at this example
- As you can see, the values 2 and 6 appear only in two cells of this unit. This means 2 must occupy one of these cells, and 6 must occupy the other
- So you can delete any other numbers in these cells
- Hidden Pairs can also be found in a column or a row
