Shenanigans
(Published on 9. May 2023, 17:11 by Jay Dyer)
Rules
- Normal sudoku rules apply.
- On renban lines (purple), digits on the line cannot repeat, and form a set of consecutive digits in some order.
- On German whisper lines (green), adjacent digits differ by at least 5.
- On region sum lines (blue), each time the line passes through a region, the sum of digits on the line is the same.
- Each line is exactly one of the above constraint types, but some have been drawn in the wrong colour. The wrong-coloured lines are exactly those lines which have the digit D on them (D must be determined by the solver).
Solution code: Row 5 and column 5.

This is so packed full of delightful nuggets of logic. And as smooth as silk, except for a bit of grit at the end - self-inflicted it seems as I had to resort to spotting a Y-wing and clearly missed something more obvious.
How does Jay Dyer apparently churn these puzzles out - has she enslaved a gang of child prodigies and locked them in her cellar? I think we should be told.

I finished in 66:12. Coming from Marty's puzzle, Mischief, to the original Shenanigan puzzle was a real treat. The logic in this one, taking advantage of the nuances of each rule type, was excellent to see. There was one particular cell in row three that blew my mind. This has to be one of my favorites. Great Puzzle!

Wow, that was a lot of fun to solve - I'm browsing through older puzzles and this one was a treat!

Just brilliant! I don't think there can be a better implementation of this ruleset.

Puzzles like this remind me that I still have plenty of room to grow as a setter. I hope my puzzles can one day be this brilliant :)

Wow! One of my favorite puzzles! Thank you for sharing.
Very interesting is this reflexive "D".

Wonderful puzzle! The mysterious digit came into play so many times, and with a nice variety of logic.

Fantastic from start to finish. Well done Jay.

Excellent puzzle. Accessible and difficult at the same time.
I doubt anyone could make a puzzle that better uses this "one evil digit" rule. You've created and mastered an entire class of puzzles all at once!
I always enjoy your puzzles, Jay.

Every step of the way was intuitive even though it took me forever to figure it out. Loved it

Nice one! I'll admit I got 95% of the way through before realising I had made an error and I couldn't find where, so I had to start again. It was a gloriously smooth solve the second time around!

Very original ruleset, very tough but rewarding. Thanks for sharing, @ Jay Dyer :)
