Chaotic Indexers
(Published on 15. July 2022, 22:15 by mathpesto)
Rules:
Place the digits 1-9 in each row, column, and region. Regions are to be determined. A gray square contains an even digit and a gray circle contains an odd digit.
A pink vertical line is a row indexer (e.g. a 6 in R3C2 indexes a 3 in R6C2).
A pink horizontal line is a column indexer (e.g. a 6 in R9C5 indexes a 5 in R9C6).
An indexer and the indexed cell are in a region together. (An indexer may index itself.)
Each blue line is in at least two regions, and digits must have the same sum for each region the line is in. (If a line passes through a region multiple times, each individual segment sums separately.)
Example:
R3C2 has a pink vertical line, so it is a row indexer. Since it is in the third row and contains a 6, it puts a 3 in the sixth row, in R6C2. R9C5 has a pink horizontal line, so it is a column indexer. Since it is in the fifth column and contains a 6, it puts a 5 in the sixth column, in R9C6.
Puzzle:
Solution code: Type the digits (no spaces) of the region containing R1C5 as follows: The digits of the region's leftmost column (top to bottom), the digits of the region's second column (top to bottom), etc.

Interesting variation, thanks with some, nifty logic and not horribly difficult.

Great puzzle! Solves very smoothly once you get into it.
