Normal sudoku rules apply.
Each line is, at the same time, a Dutch Whisper line (i.e. adjacent digits must differ by at least four), a Region Sum line (i.e. is divided by the borders between the boxes to the parts summing up to the same value), and a Modulo 3 line (i.e. each three consecutive digits on the line have three different values modulo 3).
The four digits in the corners of the grid must also produce three different values modulo 3.
Solution code: row 9 left to right followed by column 8 top to bottom (18 digits, no spaces)

Good puzzle! I have set with multi-purpose modulo lines before, so I knew some of the tricks beforehand :) Thanks!

some nice modulo math will help in sorting out the line candidates. deadly pattern at the end: did you forget something ?
I was positive that the deadly pattern reached by me is resolved by the very last rule of the puzzle, is there something more?
