Hey there! Here is another birthday present puzzle I made (and even learned how to make this page look nicer!).
I'd be grateful for each one, who might take their time for feedback

She found the ruleset at UncleLogic's "A Delicate Balance" and enjoyed it. Because I thought the wordplay and hint are hilarious, the line is named "Un10" here.

Ruleset:
Normal Sudoku rules apply: Place the digits 1-9 once in every row, column and 3x3 box.
Un10-Line: The sum of adjacent pairs alternate between being higher/lower than 10, e.g. ABCD ABCD: A+B10, C+D10, B+C10).
XV: Digits separated by a lightbulb sum to 10, the ones separated by a lightning sum to 5 (not all given).

Have fun solving the puzzle on Sudokupad!

Here is another version without any decorative elements for better accessibility, if needed: Sudokupad.
