I agree with @Joely that the renban crossing was initially a bit confusing.

As @Joely mentioned, it should be clear that it must be a single renban. If it were two distinct lines, the 'intersection' would occur within a cell, forcing the middle cell's digit to be consecutive with four distinct sudoku digits - which is certainly impossible. So, recognizing it as a single line should follow logically.

I’m unsure if there’s an 'accepted' or standardized way to document variant lines with branches, but it might be helpful to explicitly note that it’s a single renban — if only to minimize rule confusion and keep the focus on solving the puzzle

I rated this 1/5 difficulty

Another great meggen033 antiknight puzzle! Really liked the break-in for this one. I think I disagree with other commenters, as I found this one easier than most of your antiknight puzzles. I believe I've solved ~25 of your antiknight puzzles as of now, and I think this one is probably within the top 5 easiest I've seen. Even though I thought it was an easier puzzle, I very much enjoyed it!

I'm not sure if I just got into a 'groove' during this solve, but I found this to be a fairly easy puzzle. It wasn't trivial, but the logic was very approachable and clean. I think a beginner with just a bit of experience solving a handful of easy antiknight puzzles and easy killers would be able to solve this in a reasonable amount of time, without assistance.

I think the most "complex" strategy/pattern that I used was a sort of 'cage pair conflict/elimination' (sort of like an x-wing within a single row, to eliminate a cage possibility) - but I'm not even certain that this pattern was required. Even if this is a required step, IMO this pattern is MUCH easier to spot than any traditional sudoku wing. Additionally, this pattern took place in some important cells (likely to be pencilmarked early on) with only a few possible values each - and I expect that a beginner who has solved a couple easy killer sudoku puzzles would be able to spot the idea, as it didn't require any antiknight considerations and it took place all within a single row, only involving important cells within cages. You wouldn't need to do much sudoku to pencilmark the possible values in the involved cells.

All of that sounds MUCH more complicated than it is, but I'm not sure how else to describe the pattern. It is very 'thematic' among killer sudokus, and I see it frequently in killers of 1* difficulty.

Aside from maybe that pattern, all the steps were totally fair and felt well within the bounds of 1* puzzles with these rulesets. Perhaps I could see this being rated a high 1* puzzle, but it did feel quite a bit easier than your similar 2* difficulty puzzles.

Either way, I did enjoy the quick solve, and thanks for sharing!

Very nice, thank you.

Interesting that other solvers mentioned that the break-in took them way too long. For me, usually being on the slower side, this was as obvious as can be.

Joely,
There is no other way than 5 consecutives

Maybe I was half asleep today, but this was a lot harder than it seemed!

Was a bit confused as to whether the renban was 2 sets of 3 consecutives or 1 set of 5 consecutive digits. Upon solving it becomes obvious but may be good to specify in the ruleset

I have given 3 stars for difficulty. But I took way to long to appreciate the break-in. Once I got it, all began flowing nicely. Thank you for setting this fun one, meggen033!

Bit challenging puzzle but satisfying to solve. Thank you!
