- Arrows: Digits along the arrow sum to the total in the bulb of the arrow
- Maximums: The digit in a maximum cell must be greater than all orthogonally connected cells (the digit in r2c5 must be bigger than the digits in r1c5, r2c4, r2c6, and r3c5)
- Extra Region: The central cell of every region must consist of the digits 1-9 once each
The purple arrow in box 8 is purely aesthetic, and is to differentiate the two colliding arrows.
Lösungscode: Row 9, read from left to right

Wow. Now I'm exhausted. This was brilliant, but very tough.

I struggled appropriately for a 4*, and stalled a few times, but after a break came back and saw the logical deductions I'd been missing. :) In the end, very satisfying to finish. Thanks for setting!

For some reason, I really struggle with arrow sudokus, and this was no exception. I did get there in the end, though it took me over two hours, but to be fair, I did miss some very straightforward logical steps. So I have to say on the whole I thoroughly enjoyed it.
