A '''Hidden Pair''' is a [[Hidden Subset]] of size 2.

When all [[candidate]]s for 2 [[digit]]s in a [[house]] are limited to only 2 [[cell]]s, these cells must contain these 2 digits. Subsequently, all remaining candidates can be removed from these 2 cells.

== Example ==
The following example shows a Hidden Pair in the second row, for the digits 1 and 7. The red candidates can be [[eliminate]]d.
