Place the digits 1-9 in each row and column such that no digit repeats in a region. Large cells contain a single digit which counts towards 2 rows and 2 columns.
Digits along an arrow sum to the value in that arrow's circle.
Digits separated by a white dot are consecutive.
For online solution validation, non-given large cells should have the same digit in all 4 quarters.
Solution code: Row 8 and column 3 (Digits in large cells should not be duplicated in the solution code)

Quite a mad puzzle with ‘unusual’ irregular scanning, but it’s cool to see the immense power of those big cells (and also those white dots) x)

I truly loved the counting proofs required to start this puzzle, one of my very favourites. I ended up needing some paper and a pen to whittle down possible fills after that. Actually decolouring took a dose of almost-bifurcation for me.
This feels like a classic CTC puzzle, and I look forward to seeing if there was a more elegant way in if (when) they do this on the channel

Nice break-in but really tough continuation after that! Cool idea for a puzzle tho.
