I was challenged by Qodec to make a renban fortress puzzle, and, after multiple versions and a lot of tinkering, this is the result! I'm really, really happy with how this turned out, and I think the logic is very interesting! I hope you give it a try.
Normal sudoku rules apply.
Renban: Digits along each blue renban line must be a set of consecutive digits in any order, and must not repeat.
Fortress: Minimum/maximum cells must be greater than or less than their orthogonally adjacent neighbors, as indicated by the symbols bordering the cell.
Solution code: Row 2, then column 5 (18 digits, no spaces).

Very interesting reactions among the constraints. Nicely constructed and it unwinds very smoothly once past the key break ins.
