Normal sudoku rules apply.
Values outside the grid are both skyscraper clues *and* sandwich clues.
Sandwich rules: the values outside the grid are the sum of the digits sandwiched between 1 and 9 in that row or column.
Skyscraper rules: the values outside the grid indicate how many skyscrapers can be seen from that side. Taller skyscrapers hide the view of lower ones.
Example: valid rows for a value of '5' on the left side of the grid include 234795168 and 456812397.
There are no negative constraints.
All comments, ratings and feedback are very welcome and appreciated.
Hope you like :)
Solution code: row 7, column 7.

I find this puzzle *significantly* harder (like, double) than the first one.

I actually found this to be the easiest of the three. Though, in fairness, that might just be because it was the third one I did. It's an interesting ruleset, and I hope you make more with it.
@DiMono
Thanks for giving them all a go. Having spent a month or so working with this ruleset I know exactly what you mean about how they get easier once your brain adjusts to them. It's made them difficult to accurately rate I think. Thanks for all your feedback, much appreciated.

Nice rule set, nice puzzle! Thank you.
@StefanSch
Thank you very much. Not many people have solved these two puzzles compared to my others and I'm not sure why. I'm very happy someone enjoyed them though :)

Difficulty <4, please do not publish 2 puzzles of the same type at the same time, thank you!
Then, I think it is enough to use Sandwich, Sudoku, and Skyscraper for the label.
@cdwg2000
Sorry, I didn't know about that rule. I've been playing with this ruleset combination for the last month or so and I was putting the finishing touches on both of the puzzles at the same time so I thought it would be good idea to post them together. Won't do it again. Thanks for the feedback.
