Pointing Pair & Triple

What it is
A pointing pair (two cells) or pointing triple (three cells) is a candidate-elimination pattern. Inside a 3×3 box, look at where a digit could go. If every viable cell sits in the same row, the digit MUST end up in that row — which means it cannot appear in that row outside the box. The same logic applies to columns. Pointing techniques don't place digits directly; they prune candidates so that naked or hidden singles become visible.
