A '''weak link''' exists between any 2 [[candidate]]s that cannot be true (i.e. part of the [[solution]]) at the same time. These 2 candidates can either represent 2 different [[digit]]s in a single [[cell]] or represent the same digit in a [[house]].

When the 2 candidates are the ''only'' 2 candidates left in the cell or unit, they have a [[strong link]] rather than a weak link.

== Implication Table ==
For the weakly linked candidates named '''A''' and '''B''', we can make the following deductions:
* When '''A''' is true, '''B''' is false.
* When '''B''' is true, '''A''' is false.
