'''Aligned Triple Exclusion''' is a [[solving technique]] in which the solver checks combinations of [[digit]]s in a triple of [[cell]]s located in an [[intersection]]. It is an extension of '''[[Aligned Pair Exclusion]]'''.

== Example ==
An example of Aligned Triple Exclusion is shown below, taken from ''Ruud's Daily Nightmare'' for [http://www.sudocue.net/olddaily.php?id=348&sol=0 2006 November 25].

By enumerating the possible combinations of the blue cells, and striking off those combinations that conflicts with any of the yellow cells, we find that the [[digit]] 2 can be [[eliminate]]d from '''r2c6'''.

== Non-alignment ==
The enumeration technique does not require that the cells be aligned within an intersection. See [[Subset Exclusion]].
