There is a Skyscraper with the possible 7 candidates.

I did a video on Skyscrapers which will help you:

Sorry for the shameless plug but I worked really hard on the video.

Good Luck!

Code: Select all: *-------------------------------------------* | 4 9 126 | 7 5 12 | 8 126 3 | | 23 12 8 | 6 9 123 | 7 5 4 | | 2367 5 12367 | 4 8 123 | 12 126 9 | |-----------------+-----------+-------------| | 35 b27 4 | 8 12 9 | 35 c17 6 | | 1 8 35 | 35 6 7 | 4 9 2 | | 279 6 279 | 35 12 4 | 35 8 17 | |-----------------+-----------+-------------| | 59 3 159 | 2 7 6 | 19 4 8 | | 69-7 4 69-7 | 1 3 8 | 29 d27 5 | | 8 a127 127 | 9 4 5 | 6 3 1-7 | *-------------------------------------------*

Here is the Skyscraper in cells a-b-c-d. One of cells a or d must be true, so you can eliminate three 7's as shown and the puzzle then solves easily.
