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.
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.

IDK 5th attempt in as many days or so..
needs all the colours in the rainbow to solve
(tried over and over with just four plus "the five" and that was a huge mistake)

What a brilliant puzzle. This took just under two hours with on restart 20 minutes in. I filmed it so I will update this comment once I upload the video. Absolutely excellent. My first four star solve and it really made me think.

These puzzles are both really, really lovely, although definitely quite tough! Around an hour for each of them. I weirdly found this second one easier? Although I possibly missed some intended logic, cos I did do a fair bit of look-ahead.

This is really crazy. Till end I was not sure how this will have unique solution. But the twist at the end clears all the doubts. Great construction.

This was a really tough one. LOTS of Algebra, LOTS of colouring, LOTS of jumping around the puzzle to find the opposite cells on lines that therefore add up to 10 . . . Over 3hrs on this with a couple of interruptions. But a really great puzzle
