** SIMON SOLVES CRUX by JAY DYER **
Join us on Patreon (for as little as $2) for a brand new sudoku hunt from DiMono and Simon's (very very long) solve of Crux (2hours 42minutes).
/ crackingthecryptic
** TODAY'S PUZZLE **
Yesterday, we featured a new type of line (called a "Zipper Line") and today gdc shows us what this new sudoku rule can do. This is a quite beautiful puzzle - full of simple arithmetical ideas that come together SO elegantly. It would be hard to overstate Simon's love for this sudoku.
Play the puzzle at the link below:
sudokupad.app/...
Rules:
Normal sudoku rules apply. The grid is partially covered in fog. Placing correct digits reveals clues in the surrounding 3 by 3 area. Digits an equal distance from the centre of a lavender 'Zipper Line' must sum to the digit in the middle of that line. All Zipper Lines are 5 cells long, only move orthogonally and can't share cells with other Zipper Lines. Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio (ie one digit is double the other). Not all dots are given.

gdc here. So happy to see my puzzle solved here! Thanks Jaze for inventing this ruleset and thanks VikingPrime for the feedback on smoothing out the solve path (spoilers ahead).The intended solve path uses modular math to resolve box 5 - really impressive how quickly and accurately simon captured that.

The modular maths was nice for box 5. I concede I didn't clock that as quickly as Simon and ended up brute-forcing it a little bit, much preferred his / your version! Otherwise I found the solve path very smooth and enjoyable. I especially liked how it felt like solving most of a box and then getting a tiny thread peeking out of the fog begging to be pulled for the next box. Very well constructed gdc.

Those fog puzzles are really satisfying! And nicely streamline the solve path for people like me, who are terrible at scanning a full grid for the next tiny deduction. Solved it in 27:38 (Solve counter 922). Didn't cach the mod3 trick in the central box, but the lines and dots let you narrow down the options until there's only one possible arrangement of digits left :)

I LOVE fog of war! Basically every time. Generally encourages a more linear solve path, which I appreciate. Spent a while feeling stumped at the very beginning because I was accidentally trying to add up R6C6 and R7C6 to R5C6 rather than doing the opposite positions on the line. As soon as I realized that, the rest flowed very nicely. 27:27 solve time.

I finished in 50 minutes. This one was really fun. I quite enjoyed the search for the center in the fog. The logic flowed nicely from that thought.

Simon, this was an amazing puzzle and after solving it and watching you solve it I think I figured something out, fog of war puzzles are incredibly fun to solve because they help discover the logic behind the special rules of a puzzle, helping someone to learn and discover the incredible and fun interactions the rules create. So in short I think fog of war should be the new way people should be introduced to a new rule or logic in order to teach them how to spot the idea behind the absolute magic that this puzzle creates.

@ExodaCrown 9 ай бұрын

The funny thing is Simon was right about r6c3 being a 3 or 6. That was a clever break in, I asked if 9 was the second zipper center and it broke the puzzle because of the pressure the black dot was placing in the box. Then went through maximizing the centers because 9s were very restricted with the lines. Took me forever to fix the black dot in box 5 because I forgot about the zipper line rule. Then again at the end to break up the deadly pattern. All in all it was an easy puzzle and I enjoyed solving it. Took my a little under 56 minutes to solve. Edit: Watching Simon solve it made me realize how bad I am at spotting naked singles. The one in box 6 would have made my life a lot easier since that box is where I got stuck at for the longest time compared to the rest of the puzzle.

I ended up giving up kinda early based off the nature of fog. In the central box, I did get the 1 and had the correct conclusions on the geometery of the first two lines, I somehow thought the line with the doubled digit would be larger and tried to put the 9 there and the 7 as the center of the other line. When the fog didn't clear, I realized it was wrong, and it just felt like it would be cheating to keep trying digits in the fog.

Sometimes I think the option of switching to condensed rulesets would be helpful. For instance, this could be summed up as -Normal -Fog of war -Zipper lines --All 5 cells long --Orthogonal only --Can't share cells -Kropki dots For non-beginners, that's way easier to read and reference.

@jjkthebest 9 ай бұрын

I did way less maths to figure out the middle box. After you know the digit outside the box is 6 or 3 you can deduce that those can't be on the black dot. Then you can see that the bottom of the black dot can't add up to 9 with the digit outside the box. Then you can keep going the way you did.

Simon states that we know the cells of the first zipper line from the start as the line continues into into r4c4 and r6c6 but there is nothing in the rules that states we know this? The zipper line is 5 cells *long* which means it's reasonable that a terminal cell on the line as the line run the full length along it without continuing?

That started it (the digit outside box9 not being a 1). [I forget the time-mark] But when you asked "Where is the 9 in box5,'' that immediately made me wonder wherever the 8 was. The "8" also only had two spots (either going with that ''1" or a 1 outside the box for a "9" in the center of a zipper line ) Being that outside cell is a "3,6," that means the "8" has to go with that "1" for "9" at its vertex/center. Perfect Hope Simon asks about the "8" soon. I did. Thanks, Simon.

ASK WHERE THE 8 GOES IN BOX5 if it's in the lefthand circle , it's going to displace the 9 (which would need an 8 for the "1") so it's not there. There are two places now (on a line needing a 1) That "36" outside box5, now means the 8 is with that "1" for a 9 at its vertex/center. Enough with the math(s), unless it'll lead you to the 7 @18:00 or so). Thanks again, Simon. Ask that question, though. It's much simpler
