Shivers: An Introduction
(Published on 21. March 2023, 05:42 by wisty)
Draw shivers in the grid such that all unshaded cells are covered and no shaded cells are covered. Shivers are non-intersecting lines of at least length 3 which turn at 90° angles on every cell other than their endpoints. A dashed circle indicates an endpoint of a shiver. A number in a cell indicates the length of the shiver occupying that cell. Length is counted in cells, and X indicates two clues have the same value. A shiver can have 0, 1, or multiple clues.
The main puzzle may be played on Penpa+ here.
The example puzzle below illustrates this ruleset, and may also be played on Penpa+ here.
As this appears to be a new ruleset, I would also like to share a piece of information that I find helpful in solving: if you know a cell's shiver is length N, then you know the cell is a part of N/2 cells connected diagonally (meaning they would be on the same color on a checkerboard), where N/2 is rounded down if that cell is not an endpoint, and rounded up if it is an endpoint.
♡ Thank you everyone who tested this! ♡
Solution code: row 5 as a string of digits, counting the size of the shivers in each cell

Clarified that a shiver can have 0, 1, or multiple clues.

Quick question: Can a shiver connect with two clues, e.g. do the rules allow the two Xs in the example to connect?
_____
Yes, a shiver can have 0, 1, or multiple clues. I'll update the post to clarify, thanks!
Edit: I just double checked the example, it should still be unique without assuming the X's are on different lines.

Thanks for the quick answer and sorry for the misunderstanding! I didn't want to imply that there was something wrong with the example.

Wonderful puzzle idea, tricky to get started but it flowed beautifully once I got used to the deductions required. Definitely hope to see more of these! :)

Thanks a lot for this fine puzzle and congrats on developing this ruleset! I really like the new way I have to think while solving :-) .

Lovely puzzle. I often took the case-checky route instead of the elegant route, but still enjoyed myself immensely.
