A '''Skyscraper''' is a [[single-digit]] [[solving technique]] which uses a particular pattern of [[Turbot Fish]].

It has been introduced as a separate technique, because the Turbot Fish technique does not use a single pattern and is not easy to learn by the average Sudoku player.

Here is an example:

[[image:skyscraper.png]]

The [[candidate]]s for [[digit]] '''4''' in [[row]]s 4 and 7 are [[conjugate pair]]s. Since the 2 candidates in [[column]] 7 cannot be true together, at least one of '''r4c2''' or '''r7c1''' must be true. They could also both be true. We call this a [[connected pair]]. The two red candidates can be eliminated, because they can both [[see]] '''r4c2''' and '''r7c1'''.

== Note ==
A Skyscraper is also a [[Sashimi X-Wing]]. Also, Skyscraper can be replicated using [[Multi-Colors]].

== Practice ==
The following is a practice puzzle for [[2-String Kite]] and Skyscraper. The other techniques that are required are [[SSTS]] minus the [[coloring]] techniques. It is generated by [[Simple Sudoku]].
