Normal Sudoku rules apply.
159: Digits in the shaded cells in columns 1, 5, and 9 indicate the column in which 1, 5, or 9 (respectively) appears in that row.
Modular Lines: Every three consecutive cells along a teal (MOD) line must have a different modulo 3 value (i.e. one from each of the three sets, {1,4,7}, {2,5,8} and {3,6,9}).
Renban: Digits on a purple (REN) line form a non-repeating set of consecutive digits in any order.

Phew! Took me about an hour to solve. Quite a challenge, but an enjoyable one. I think a good 35 minutes was just trying to get the first digit.
