It was an absolute pleasure collabing on this with the excellent Justin Vitanza (AKA Puzzle Pusher)
Rules:
- Normal sudoku rules apply.
- Unique N-Lines: ALL lines in the grid are N-Lines. Each N-line is composed of one or more non-overlapping sets of adjacent digits, each of which sum to N. Every line has a different N value.
- Coloured lines (not including the grey ones) each have an additional rule:
- Renban (pink): Digits on a pink line form a non-repeating consecutive set, which can be arranged in any order.
- Even Sum Lines (darker blue): All the digits on a darker blue line sum to an even number.
- Prime Lines (purple): Adjacent digits on a purple line sum to a prime number.
- Anti-Kropki Lines (red): No two digits anywhere on the same red line are consecutive, or in a 1:2 ratio (but they may repeat).
- Same Difference Lines (turquoise): Each pair of adjacent digits on a turquoise line have the same difference. This difference must be determined for each turquoise line.
- The grey perimeter can be used for making notes.

Lovely flow. Relatively easy start, then had to keep thinking all the way till the end.
A great puzzle!

Great setting and not a slog despite the potential.
BTW I don't understand the people who can do this without a separate note-taking area.

4/5 on difficulty for me - it was time-consuming, but I didn't find any of the logic to be especially big leaps. Very note intensive - I definitely appreciated having the extra square to track which Ns I had and which I needed

Was great! The grid looks intimidating but after the breakin and copious notes things flow smooth.

This was such an excellent balance between normal sudoku, global considerations and intricate logical deductions. Spectacular!

I absolutely agree with heliopolix, this was N-tastic!
