Rules:
Normal Sudoku rules apply. Place the digits 1 to 9 in every row, column, and blue-outlined 3x3 box.
EQUAL SPLIT LOOP - Shade some cells to form a 1-cell-wide, orthogonally-connected loop that does not touch itself, not even diagonally. Split the loop into non-overlapping segments so that digits do not repeat within a segment and each segment has the same sum.
RIVER - Split points of the loop cannot occur on the blue river (loop segments must form a "bridge" when crossing the river).
CASTLES - A digit in a castle gives the number of loop segments in the same 3x3 box as that castle. A loop segment is counted if at least one of its cells appears within the 3x3 box. Castles may be on or off the loop.
FLAGS - Each flag touches one loop cell and one non-loop cell. Digits joined by a white flag must be consecutive, and digits joined by a black flag must be in a 2:1 ratio.

A pleasure to solve, albeit not a terribly difficult one. Well deserving of the 100% rating so far.

Thanks for the fun and surprisingly approachable puzzle!
FYI I played on mobile and all the flags were black.

Very cool twist on a familiar rule. The castles were a great idea for restricting (what seems like) a very loose constraint.
**
Thank you for your comment, MaizeGator! We are glad that you liked the puzzle. And you are right: At first, the Equal Split Loop is quite flexible. It is curious how quickly it gets restricted once a few things get narrowed down though.

Really enjoyed this puzzle, which seems inevitable when these 2 hooligans team up together. Thank you both for the fun!

Thank you for your comment and testing the puzzle, Calvinball! It is great to hear that you enjoyed the puzzle. "Hooligan" is a word I get not described with too often. But I agree that Nordy and I are a "dangerous" team. :D
