N-sums Sudoku--Skyscraper
1. Classic Sudoku rules apply;
2. The numbers outside the grid indicate the sum of the first N cells in that direction.and N is the number of observations of skyscrapers at that location.
3.Standard Skyscrapers:Insert a digit from 1 to N into each cell in the N by N grid so that no digit repeats in any row or column. Also, each number in the grid represents the height of a building and the clues on the outside of the grid indicate how many buildings can be “seen” when looking from that direction. Taller buildings block the view of smaller buildings.
Lösungscode: Row 3,Coloum 7.(A total of 18 numbers).

I am also learning how to use Penpa+. I basically don’t know how to verify the answers on Penpa+. If possible, I will study the manual carefully. I am better at using PZV and PUZZ. F-puzzles is limited by the network and cannot be used. I think Penpa+ will be a more general puzzle setting tool, but it may need a guide, and there are some problems such as rich puzzle types. Maybe he Will gradually be improved. Thanks Dandelo! Thanks Swaroop!
There may be two other variants of the X-Sums rule set, which may be an interesting combination.

Very nice. At a first glance it seemed a little bit artificial to invent the next ...-sums by mixing skyscrapers and x-sums. But it is a very harmonic ruleset and allows tricky conclusions. And, as always, a good solution path.
In penpa+ you have to turn 'border' on. Maybe not all solvers know this. And 'R' should be on, too. What I've learned recently: If you are in edit mode and there in solution mode and there you turn border etc. on before creating the link for solver mode, it is saved and the solver is immediately in the best setting.
Here's a link to penpa+ with these settings and with solution check: https://git.io/Jts0T
But the solution check works only with empty circles. I don't know how to create a solution check that checks the grid, but not the circles. I'll ask Swaroop if this is possible.

The ○ symbol provided by Penpa+ link is used to mark observation numbers of skyscrapers. If necessary, you can enter numbers. If you don't need it, please ignore it.
