- Normal Sudoku rules apply (each box, column and row contains the digits 1 to 9).
- Clues outside the grid indicate the sum of the digits between the 1 and 9 in that row/column.
- Digits along an arrow must sum to the digit in its circle. The arrows of r3 and c3 go straight (no turn in r3c3).

great puzzle! One of the hardest puzzle ever. I really enjoyed it, but it would be perfect if there were a notifacation about the arrow in the up right corner. I thought it's a three-cell arrow at first and suffered for hours.Tell me I'm not the only one.

Goodness me, what a brilliant puzzle! I found it pretty challenging even with the given 9. Some cool, unique logical steps involved. Thanks ICHTUES!

I have started solving this puzzle before you added the given 9. Then, even after you added the 9, I tried to solve the puzzle without using it but after spending more than half an hour and reaching nowhere I didn’t resist too much and used the given 9. Once I used the given 9, the puzzle started to open up slowly and very nicely. I think the puzzle is not extremely hard after the given 9, and it involves very nice logic throughout the solution path.

Easily one of the most brilliant and insanely mindblowing puzzles I've ever solved!
Incredible logics all over the place and I loved every moment I discovered a new one, tough but rewarding. Just wonderful and astounding construction! ;)

added the given 9, until now it was just too hard and not nice.

I was about to ask the condition for r0c8 and r0c9 on 5 cells arrow, but soon later realized that they’re also sandwich sums so nevermind :)
