Urban Sprawl
(Published on 27. July 2022, 18:56 by jwsinclair)
Normal sudoku rules apply.
Numbers in the grid represent the heights of skyscrapers, and clues outside the grid indicate the number of skyscrapers visible in that row or column, looking in that direction.
Digits in cells separated by a black dot have a 1:2 ratio. All possible dots are given, including along the edge of the grid and between cells outside the grid.
On thermometers, digits increase from the bulb.

ziemlich unklar ist, welche Regeln für die Reihen/Spalten außerhalb des Grids gelten, müssen die auch die Ziffern 1-9 enthalten oder dürfen sich dort Ziffern wiederholen und ist in Spalte 4 unten auch eine evtl Folge 3-6-3 erlaubt?

Ja, Ziffern können sich in den Zeilen/Spalten außerhalb des Rasters wiederholen (aber die negative Einschränkung gilt immer noch). Eine Folge wie 3-6-3 ist erlaubt, wenn sich zwischen den Zellen schwarze Punkte befinden und die letzte Ziffer außerhalb des Rasters liegt.
Yes, digits can repeat in the rows/columns outside the grid (but the negative constraint still applies). A sequence like 3-6-3 is allowed if there are black dots between the cells and the last digit is outside the grid.

A really intersting combination of constraints. I made it much harder for myself because of a wrong assumption about the negative contraint but got there in the end. Very enjoyable puzzle :-)
