Practise: Hidden Pair
Look only at the highlighted row or column. Which two digits have only these two homes?
The two prepared note cells are in the highlighted unit. Do not look for a final digit yet: find the two digits that occur only here.
Example 1 of 4
Your turn first
Which two digits belong only here?
Look only at the two prepared note cells in the highlighted unit. Which two digits occur in exactly these two cells? Do not place a digit yet; first find the pair.
Remember
A Hidden Pair is simple: if two digits can each go only in the same two cells, every other note in those cells can be removed. The pair itself does not decide their order yet.
