This is a “Twisted Tuesday” puzzle variation.

Theme: Arithmetic Series

Rules: Variant of Skyscrapers rules. The numbers outside the grid represent the sum of the buildings seen in that row or column. For example, if a row is 12534, the clue from the left would be an 8 (1+2+5) and from the right would be a 9 (4+5).

Answer String: Enter the 3rd row from left to right, followed by a comma, followed by the 5th row from left to right.

Time Standards (highlight to view): Grandmaster = 1:30, Master = 2:45, Expert = 5:30

Solution: PDF

• Nice combination of latin square logic with skyscraper and sum logic.

• Francis says:

Not too hard, but I liked the conciseness of the construction.

• Scott Handelman says:

I couldn’t even start without writing down all the possibilities for each number, which thankfully turned out to be much fewer than I thought. I don’t think I came even close to Expert time…that shows my weakness with Skyscraper logic in general, but sum puzzles have always been difficult for me too.
