Index Field
(Published on 26. June 2023, 19:59 by zzw)
Normal Sudoku rules apply.
Digits may not repeat along the marked diagonal.
Adjacent digits on a green line must differ by at least 5.
For every cell, a digit X in column N means the digit N appears in column X in that row (like the 159 variant, but for all columns). For example, a 5 in r3c2 indicates there is a 2 in r3c5.

Very elegant puzzle setup, and quite tricky even if you know the trick!
