[Eng] 0-8 Arrow Sudoku, by Akash Doulani (WPF Sudoku Grand Prix 2024, round 7, puzzle 11) 

Beautiful solve path 👌 ✨️

A wonderful puzzle! Great set-up and each of the key deductions are amazing. I, like Akash, didn't see the parity argument at all and I must say I struggled with that part of the solve until I watched Akash solve it a few days ago and the way he explained it is very nice and totally makes sense in my head. I have to say the inclusion sudoku was the best puzzle of the round for me, but both this puzzle and the XV (-) were right up there too.

A very nice video. I did not realise the parity part of the arrow sums in boxes 4 and 8. It was a clever find. I learned a lot of things watching you and Ashish solve this puzzle.

I spotted one more thing during the solve.... In boxes 1 and 9, 1 cant be on the same arrow as 0 (maximum sum would be 6) !
