River Crossing

Normal sudoku rules apply.
Divide the grid into 3 orthogonally connected sections such that each pair of sections shares an edge and no 2x2 square in the grid belongs to a single section.
A digit in a circle indicates the number of circles in its section.
On section-sum lines, all adjacent groups of digits along the line which are part of the same section have the same sum. No line can be entirely in one section.
Lösungscode: Row 4 then column 4

This is a masterpiece! Even though I've set some 3-colors YY in the past, it still took me well ~2 hours to finish! I really like the extra logic it offers compared to 2 colors. I've yet to see one with 4 :)

Peacherwu. No, lines can have different totals. They're essentailly region sum lines but use the coloured yin-yang regions rather than the boxes.
Seriously clever setting and very tough. Very much deserving of the perfect rating :)

So the equal sums of different lines must also be the same?

I have a real love of these yin-yang+ style constraints! This was an excellent puzzle.
I can't always spot a setter's "fingerprint" so to say, but I do feel like you have a distinct style that I really enjoy Icy Fruit (even though I can't solve a solid third of your puzzles).

Yeah, I'd just commented literally as the fix came in (and swiftly deleted). Hopefully the fix doesn't alter the difficulty too much, as that was a great ruleset leading to a really fun and hard solve (deadly pattern aside).
