Cutting Corners
(Published on 26. January 2025, 20:02 by sujoyku)
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Index Lines: Each turquoise line is an Index Line, i.e. the digit in the Nth cell along such a line (starting from the diamond) indicates the position along the line where the digit N appears. For example, if a diamond cell contains a 3, the third cell along that line must have a 1.
Here you can solve the puzzle online:
Solution code: Row 5 from left to right (9 digits in total)

Gonna go against the grain and say this felt more like 4 stars than 3 stars for me... but such comments are a bit pointless anyway because everyone will have different subjective views on difficulty, and the average rating from solvers is the real meaningful stat.
Anyway, this was a brilliant puzzle, beautiful break-in and a lovely ending too! It took me ages to solve but it was totally worth it

Thank you! Delightful puzzle, and thoughtful but fair deductions the whole way through. I think I'm getting the hang of index lines now...

Felt more like 2 rather than 3 stars to me, but very satisfying all the same. Very nice geometry, clever deductions until the very end!

Hmm... indexing lines seems like a fun ingredient for a sandwich...
**
Definitely! I think they could also be a fun combo with other outside clues like X-sums. Thank you for commenting, RockyRoer!
