Sudoku How To Technique: Hidden Triple

Extending the rule of Hidden Pair it uses the concept of “If there are three unique hints in three cells within one container, then we know that no other hints could be valid within that container using process of elimination”. Remember all three cells don’t need to have all of the valid three HINTS, they just need to make a unique combination of the three HINTS. The diagram shows COLUMN C8 CELLS R4C8, R5C8, and R9C9 having the valid values of {6,7,8}.
