Fill in the grid with the digits 1-9 so that each digit appears once in each row, column, and 9-cell orthogonally connected region. The regions must be determined by the solver. Digits outside the grid give the sum of the first N digits in a row/column where N is the number closest to the clue. Additionally, the value of N will have one of the following properties:

A. Show the distinct number of regions in that row/column

OR

B. Show the number of skyscrapers in that row/column starting with N seen from the outside of the grid.

The grey line is a region sum line. On the line, digits on the line have an equal sum N within each region the line passes through. If a line enters a region more than once the total is counted as one sum. The line must visit every region. Digits separated by a V sum to 5, and those digits must be in different regions. Digits separated by a X sum to 10 and must be in the same region. Digits separated by a white dot are consecutive and must be in the same region. Digits separated by a black dot have a ratio of 2:1 and must be in different regions. Not all XVs and dots have been given.

This is my first attempt at a chaos puzzle, so any feedback or comments would be appreciated. I feel the difficulty is between 3.5 and 4 stars. [Thanks to some users for feedback, the puzzle had an error which was addressed.]
