A '''conjugate pair''' is a pair of [[candidate]]s with a [[strong link]]. They are the last 2 candidates for a single [[digit]] in a [[house]] they share.

Different terms were introduced for the same concept when the Sudoku community developed their [[solving technique]]s. The term '''conjugate pair''' is mainly used in [[coloring]] techniques. The term '''strong link''' refers to the [[link]] between 2 candidates, but does not include the candidates themselves, whereas the term '''conjugate pair''' clearly refers to the candidates. Furthermore, a strong link can also exist between the last 2 candidates in a single [[cell]], but it is not customary to call these 2 candidates a conjugate pair.

There is also a difference between a conjugate pair and a [[connected pair]]. In a '''conjugate pair''', only one of the two candidates in the [[house]] can be true. In a '''connected pair''', at least one of the candidates must be true, but it is also possible that both of them are true. The only certainty we have about a connected pair is that they cannot both be false at the same time.
