Index Lines
(Published on 18. August 2024, 21:26 by marty_sears)
Rules:
- Normal sudoku rules apply. On an index line, the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears. Eg: 3214 would be a valid line; the 1st digit, 3, indicates that the 3rd digit is a 1, and so on.

Nice puzzle! Took a while to get my head into these lines. But then it solved smoothly. Thanks.

Very lovely puzzle. I especially liked the deductions involving the dangly bit in box 4.
For the record, this variant is not new. <a href="https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000GNC">Kafkapharnaum</a> mentions them as having been invented by GM Alexandria on Discord, though it's possible it's even older than that.

I think the link is wrong: it takes me to a sudoku maker (?)
Marty: thankyou for letting me know - I have fixed it now :)

First time I've come across this ruleset. Had me in knots at first, which I enjoyed untangling!
Fun puzzle, thanks!

I had trouble kicking my brain into gear for the indexing, but once I was able to pick up on the concept, I was able to get through it pretty straightforwardly. Thank you for the puzzle!

What a great new ruleset! I always love when one type of clue is enough to get a unique solution. Quick and easy but also very fun to solve.
