Rules: Normal sudoku rules apply. If a cell with an arrow contains the digit N, then the straight line starting in that cell and extending N cells in the arrow’s direction (including the arrow cell) is a valid region sum line: it must cross at least one 3×3 box border, and box borders divide it into segments with equal digit sums.
E.g. if r1c1 = 5, then r1c1+r1c2+r1c3 = r1c4+r1c5.
Lösungscode: Column 6 (top to bottom)

Absolutely phenomenal, as usual. So many moments felt impossible, until you realize that one trick or another tells you absolutely everything if only you can think of it. Definitely 4/5 on difficulty for me.

Whow, that was cool! I took a couple guesses that worked out -- now I'm going to go back and do it the proper way :)

Brutal and devilish but pretty neat and fun! Thank you for setting the puzzle.
