Normal Sudoku rules apply.
Additional rules:
German Whispers: Digits on the green line must differ by at least 5 from their neighbour.
Renban: Digits on a purple line are non-repeating consecutive numbers in any order.
Kropki: White dots connect consecutive cells, black dots connect cells in a ratio of 1:2. Not all dots are given.
Arrow: Digits on arrows sum to the number in the circle and may repeat if allowed by other rules.
Killer: Digits in cages sum to the number in the corner of the cage and can't repeat within a cage.
Kropki: digits with a white dot between them must be consecutive. Not all dots are given.
(Also, watch Drawfee :))
hint in case you're stuck:
consider the Phistomefel Ring.
Solution code: Column 1

Is Phistomofel meant by "the f word" and "the trick" or is there more to know? I am finding this one hard to break in.

IF you know the ring then this is a relatively easy puzzle.
I'm not sure it has a unique solution though as I think I found 3.

Excellent tribute to one of my favourite YouTube channels! :D

Difficult to break in even knowing about the ring, but a fantastic puzzle. Very fun solve.

I enjoyed it. Difficulty is very easy if you know the trick. But will be difficult if you don't. Fortunately for me, I know the trick.

Really loved the logic here. Took me a bit long to realise I was meant to chase the 5 around but as soon as I spotted that, it all flowed.

Very nice! I think the Kropki dot in box 2 is superfluous, but I enjoyed the logic flow very much!

Very beautiful logic indeed, but for my taste not below 3 stars since the break-in matters most as without it no “clean” solve is possible. Was a joy to finish after getting slightly panicky for a while.

Really nice Puzzle. Beautiful Ring-Whisper interactions. Thank you.

Brilliant setting, to create a puzzle that looks intractable, but is actually quite easy, if you use the f-word.
This puzzle is a clear example demonstrating the need for a two-parameter difficulty rating: 4/5 to start, then 2/5.
Only an expert solver will be able to reasonably start this puzzle, although any intern can finish it. Why? While an intermediate solver will know the f-word, they will look at it, conclude that it doesn't help, and will then go wandering off on a bunch of wild goose chases. It takes an expert to look at the situation deeply enough to find the key.

Approachable with really smooth Phistomofel ring logic.
