This is a puzzle that I created for Bellsita's birthday, which they encouraged me to share with all of you. Ratings, comments, and feedback are much appreciated! Please feel free to reach out to me on Discord if you have any comments or questions. Please also feel free to try my other puzzles here.

Rules:
- Normal sudoku rules apply.
- Remote sums: A digit X in a cage points to a second digit Y located X cells away vertically or horizontally. The number in the top left corner of the cage indicates the sum of X+Y. Digits in cages may point to cells inside or outside the grid.
- Numbered rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.
- Region sum lines: Digits along blue lines have the same sum within each region it passes through. The gray area outside the grid is considered one region for purposes of this rule. Different lines may have different sums.
Here is an example image to clarify the indexing for the remote sums cages (small numbers in cells indicate steps away from the cage):

Lösungscode: Column 3 of the sudoku grid (9 digits)

Broke it twice but finally got thru on 3rd attempt. Brutal, but great fun. Thanks for sharing, @ dumediat :).

Brilliant! All clues which look unrelated to each other cooperate very nicely!

Very fun! This made me like region sum lines a lot again after a couple puzzles in the past turned me off of them
