Purple and Green Snake
This is my 1st time constructing a sudoku where a snake/line must be drawn on it. I hope you like it, and well done if you can find the intended endgame to this sudoku.
Rules: Normal sudoku rules apply. In cages, digits sum to the total in the top left corner Digits along a between line are strictly between the digits in the two circles. Digits along a thermo must increase from the bulb end. Clues outside the grid sum up the digits along that diagonal. Digits along a green line have a difference of at least 5. Draw a snake from R1C9 to R9C1. The snake cannot touch itself orthogonally (but can touch itself diagonally) Digits along a snake must satisfy 1 of these 2 criteria 1) Orthogonally connected cells are consecutive (renban) 2) Orthogonally connected cells have a difference of at least 5 (i.e.) 82123 is a valid portion of the snake as 8-2 satisfies criteria 2 while 2-1-2-3 satisfies criteria 1
Solution code: All digits that are on the snake with no spaces. (21 digits total)

Nice puzzle! I would suggest clarifying the rules somewhat with regard to the snake, and especially the 1st criteria. You add (renban), which to me suggested a "group of NON-REPEATING consecutive digits in any order". But, I think you mean that applies just to any isolated pair.
Although the rules might technically be correct, I understood them as the snake is divided into sections, which are either renban or german whispers. Which made it VERY hard to try to figure it out :) I did feel I had to add an assumption (that any pair must be consecutive).
An easy way to make it clearer (to noobs like me) would be to add to the example: "..., while 82132 is NOT valid because 1-3 is neither consecutive or differ by at least 5".

Interesting puzzle. Thanks, @ wildhound007 :)

Ich verstehe nicht, wie die Schlange aufgbaut sein soll :( Das Beispiel hilft mir auch nicht weiter.
Bedeutet Kriterium 1, dass die Zahlen direkt aufeinander folgen müssen oder eine Gruppe aufeinanderfolgender Zahlen in beliebiger Reihenfolge?

@Dag H Thanks for your comment. The snake is a puzzle within a puzzle, but the snake should disambiguate the deadly pattern towards the end of the puzzle.

Nice puzzle. I think the rules could be a little clearer that a) the 4 central thermos all end at r5c5 and b) drawing the snake isn't part of solving the sudoku, but an extra puzzle on top of it. At first I thought every square on the snake would give me only one possible next square and I could use that in solving the sudoku.

@Langa It’s R5C5. All 4 thermos meet at the same point

Where do the four thermos leading into box 5 terminate?
