Central Index
(Published on 8. February 2025, 07:28 by mimec)
This puzzle took some time to create, but finally I was able to find a combination of row/column indexers and Renban lines which works really well. Have fun solving it, and I appreciate your ratings and comments.
Rules:
- Normal sudoku rules apply.
- Digits on a purple Renban line must be a set of consecutive, non-repeating digits (in any order).
- Shaded cells are simultaneously column and row indexers, i.e. digit X in a shaded cell in row R, column C indicates that digit C appears in column X in row R, and digit R appears in row X in column C (see example below).
- Digits connected by an X must sum to 10. Not all Xs are given.
Example:
In the following example, the 2 in r4c5 forces a 4 into row 2 and a 5 into column 2. Similarly, the 8 in r6c4 forces a 6 into row 8 and a 4 into column 8.
Solution code: Row 9

The break with purple lines on left was tough! Thanks for setting up!

This puzzle (like many index puzzles) was hard to wrap my head around at first, but then I found it has a nice flow. Thanks for sharing!
