Put the digits 1–9 in each row, column, and box without repeating.
Cells a knights move and kings move away (in chess) can’t contain the same digit.
Digits along a renban line form a set of consecutive digits in any order that don't repeat (e.g. 5423).
Clues outside the grid give the sum of the digits strictly between the 1 and 9 in the associated row/column.
Solution code: Column 1

Very fun, not too hard. Nice little logic puzzle at the end to get the disambiguation.

Takes a bit of time to do all the colouring, but very nice logic at the end to disambiguate everything.
I didn't understand why the upper right renban is a triangle instead of just a L shape.
