NIL River
(Published on 27. February 2024, 13:57 by M.K.)
Rules:
- Normal sudoku rules apply, with one exception: Place a 0 in every row, column, and 3x3 box such that they sum to the same total.
- Digits in a cage cannot repeat and sum to the small number in its corner.
- Draw a 1-cell-wide river which flows orthogonally and does not branch or touch itself (even diagonally).
- The river flows from r2c1 to r1c8, as indicated by the arrows. It cannot cross a cage and must enter every 3x3 box exactly once.
- Digits on a river segment within a box must be consecutive in any order.
- River digits seperated by a box border must be in a 1:2 ratio.

Rephrased the first rule to be more clear about how many zeros are allowed.

@sanabas: I was surprised myself how nicely that river flows. ;-)

A bit tricky to get started, flowed nicely after that.
@yttrio: It's normal sudoku with nine digits from 0-9, just need to work out which nine digits are used, which one is missing.
