Skyscraper

Coming soon.

A Skyscraper is a single-digit pattern consisting of two strong links (conjugate pairs) in parallel rows or columns. The links are connected at one end, forming a shape like two tall buildings of unequal height.

The Skyscraper is a special form of Turbot Fish and can be seen as two linked Sashimi X-Wings. Any cell that can see both "tops" of the skyscraper can have the digit eliminated.

This technique documentation is under development.
