The Door around the Corner
(Published on 16. July 2023, 20:00 by XeonRisq)
- Normal sudoku rules apply.
- Reflected Numbered Rooms: Clues outside the grid indicate the digit X which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction and N will always refer to the first occurrence of X.
- The arrow determines the diagonal direction of the clue AND once it hits the edge of the grid, it reflects at 90 degrees and continues until it hits the next edge at which it stops (always nine possible cells for each clue).
- Entropic Line: Any set of three sequential cells along a biege line must contain a low (123), middle (456), and high (789) digit.
- Anti-Entropic Line: Any set of three sequential cells along a blue line must NOT contain a low (123), middle (456), and high (789) digit.

Fantastic puzzle. Thanks, @ XeonRisq:).

Always a pleasure to see you again Bankey. Thanks for the gracious feedback, and of course taking the time to give this one a try.

Stunning puzzle! And not too difficult, the opening is just the work of a genius.
-----
Thanks damasosos.. I'm humbled by your praise and very happy to see it was and enjoyable ride.

Even if I try it and cant solve it, I appreciate the insight that a diagonal reflection off one wall will (always?) be 9 tiles long
-----
I appreciate the attempt, the feedback, and the solve. If you get stuck, you can check out the CtC video, but the ramifications of the intended break-in wasn't exactly used. And if the diagonal reflects only once, then it will always be nine cells.

Beautiful puzzle. One of my favorites I've done.
In relation to the comment by Silverbyte I think deflect rather than reflect may be a better word. I understood what you meant, and until seeing his comment didn't even consider the other one but I can see how reflect could indicate a mirror like relation that is symmetric on the 90 degree rotation. But like I said that interpretation wasn't even my radar until his comment
-----
I do see now how it would be easy to mix up the rule depending on how you draw the lines. I really didn't consider it when I was developing this twist on the rule. So as you've said, it really depends on how it is initially perceived as I didn't consider this much either until the comments. I appreciate the lovely feedback and the solve.

I was a bit nervous starting this one (**** puzzles are usually beyond me), and it took me almost an hour and a half, but I'm so glad I stuck with it, because this was SUBLIME.
-----
Thank you for the kind words, and I'm glad you stuck with it. I believe it's only 4-star due to the novelty of the constraint, and how little exposure anti-entropic lines have gotten thus far.

Stellar logic!
I did want to add that the 90° reflection rule was a bit ambiguous since I didn't know at first whether it meant that the line from the diagonal arrow reflects or the cells themselves do.
For example, the 5 clue in column 7 could be either of these bounces:
(1,8);(2,9);(3,9);(4,8);...
(1,8);(2,9);(3,8);(4,7);...etc
Just a minor example would've helped clarify (for anyone wondering, it's the second option)
-----
Appreciate the solve and the detailed feedback. Though I would think that your first example does not reflect when it hits the edge, rather it goes parallel to the edge one cell then reflects. If I receive any more questions about how the line reflect, I will certainly explain further in the rules.

Nice puzzle! The diagonal rules are really interesting, I did a skyscraper puzzle like this the other day and it was just as much fun. I hope we see a lot more of this in the future!
-----
Appreciate taking the time to give this one a try and of course for the feedback. This was truly only for exploration, but if solvers really like this variation, I'm not opposed to creating more puzzles with this constraint.

Nice "twist" on numbered rooms, works nice with the entropic lines.
Chasing all those digits around reflected diagonals (I ended up using lines to trace) felt like a hall of mirrors, trying to see where they ended up :)
-----
Thanks alot for the solve and detailed feedback. I did see a couple of test solves of this and the strategies used were interesting, of which some did draw lines to keep up with each clue but not all did. Very fun to see all the approaches on this one.

Well I think I'm done solving Numbered Room puzzles after this, because I'm confident this is the best Numbered Room puzzle I've ever solved or will solve.
-----
I don't think it's possible that I will ever receive a better response to a puzzle than this. I am grateful for your solve/feedback and humbled by your praise.

Cute break-in :)
-----
Yeah, I thought it was kinda interesting when I found it, so I just rolled with it!!

That's an amazing puzzle, wow!
-----
Appreciate the kind words and thrilled you enjoyed the puzzle.

It is a stunning puzzle. Some parts are tricky but not monsterously difficult. Love it!
-----
Thank you for the feedback and very grateful for the compliment. I agree some parts are a little tricky but manageable (a little surprised difficulty creeped up to 4-star).

Just wow!

Thanks! Glad you enjoyed it!!

Fantastic puzzle, I wasn’t sure I’ll be able to solve it but once I found the breakthrough point everything fell into place like magic! Wonderful well done!
-----
Really glad you found the puzzle enjoyable. And I was also concerned about difficulty given this twist to the constraint, but I'm happy with the result. Thanks again for the solve/feedback.

Very beautiful breakthrough in the beginning, really creative
-----
Appreciate the kind words, and grateful for the solve.

Numbered rooms variation? Yes please!
Very cool idea, very nice execution. :)
-----
Thanks for the compliments. However, you already know how I feel about this outside clue constraint, but in the end, it was very much worth exploring this variation.

Wonderful and novel opening. At first I thought I would never get there but it's not super complicated, just different from anything I've seen before.
-----
Thanks for the solve/feedback, and I agree with you completely. The reflecting outside clues intermixed with the entropic/anti-entropic lines allows for some interesting twists.

Stunning puzzle! I really hope this gets picked up by CTC, it would make for a great video! :)
-----
Wow.. That is very strong praise, I am humbled by your compliments. And thanks again for taking the time to give this one a try.

Brilliant puzzle! Thanks:)
-----
Hey Elliott, great to see you again, glad you enjoyed the puzzle and appreciate the kind words!

Wonderful logic, and pretty approachable!
-----
Thanks for the kind words and the solve. I couldn't decide on 3 or 4 stars for difficulty, but in the end, your assessment was right on point.
