Naked Triple: three cells, three digits
The naked triple extends the naked pair to three cells. Three cells in a unit together hold only three candidates and lock those digits to themselves. Click through a real example step by step below.

How the naked triple works
Look for three cells in a row, column or box whose candidates together use only the same three digits. Each of the three cells may hold two or all three of them, none has to carry all three. Because those three digits must be spread across exactly these three cells, they cannot appear anywhere else in the unit and can be removed there. The naked triple is the direct big brother of the naked pair and often works where the pair alone is not enough.
