(Published on 28. March 2025, 06:00 by NurglesGift)
Normal sudoku rules apply.
Orthogonally adjacent cells can not sum to 5 or 10.
Digits in a cage can not be orthogonally adjacent with a consecutive digit.
Each line must be given 1 bulb at one of the line-ends.
Two lines of the same length and same color are connected X lines.
Counting from the bulb, the first cell of each connected X line sum to 10. the second cell of each line sum to 10 etc.
5 can never be on a line.

really enjoyed the colouring this time, not the math so much tbh
(never like if a puzzle need "pen and paper" too)

Fun but tricky puzzle! Had me stuck twice, one in the break in and once in the end...

Great coloring puzzle, took a lot of thought to disambiguate the ending.

The entire XV series by NurglesGift is simply amazing. This is exactly the kind of puzzles I like best: simple and few rules, and the solution path is always strictly logical and straight forward.

Great fun, and not as hard as it looked at first sight, once I got the idea how to start. It certainly helped me that I have gained some experience in these kind of puzzles through this series.

I restarted this puzzle a number of times due to silly mistakes. That said, this puzzle is so amazing and I am just wondering how someone could make such a well-structured puzzle from scratch. Well done!
