- 1. Chaos Construction: Divide the grid into 9 regions that all consist of 9 orthogonally connected cells each. Place the digits 1-9 in every row, column and region once each.
- 2. Inside X-Sums: Clues on the grid show the sum of the first X digits along the given direction, including themselves, where X is the digit in the clued cell. Furthermore, the first X cells all belong to the same region, and there are no other cells that belong to their region in the direction of the arrow. A ? can be any number from 1 to 45.
Solution code: Digits of the only region that contains the center cell (r5c5) in normal reading order.

Prevented the CC from having 2 solutions, that was an oversight.

The 2 CC solutions make me rather confused in the last part, although it is beautiful before that.
.proxz14's response: That was a total oversight, I didn't consider that option at all, now I've added a clue that's otherwise not so impactful to fix this.

I feel there might be a double solution in terms of CC, considering the northernmost regions can be constructed in two ways that don't break the puzzle. Still, beautiful solve up until that point.
