Puzzle #489 - Is it a Sloop? (Yajilin)

Evandar (who did the best of the Witness Randomizer community on Yajilin Yacht) requested at first a 10x10 Yajilin with the minimum number of clues. I shared an existing 3 clue as there are a couple of those, and got a second request of a "mostly 0 Yajilin". This wasn't exactly what Evandar requested, but he liked the trick I put in this puzzle so I count it as a win.

Puzzle #488 - Dragon! (LITS)

I made this LITS puzzle for ADGOD, who had the most viewed replay during the contest for Yajilin 13. The story here is after a poor solve on puzzle 11, he thought he was out of contention for any good placement (which turned out to not be true) but ended up drawing some dragons. Since the solution check only cares about the loop... well, you get some fun pictures. Most didn't save into the replays but this one did.


The first request was a Double Choco with a dragon-shaped layout, but that proved pretty unworkable. This might not be dragon shaped, but I told ADGOD to trust me and he was very pleased with this one in the end.

Puzzle #487 - Qurve Data

Also on the topic of Secret Solver, Eric Fox got a very delayed puzzle. So I whipped up a consolation Curve Data puzzle so he'd at least have something personalized to solve. I like making Curve Data now. Turns out all it really took was an understanding of how they work.

Puzzle #486 - Masyu Rings

Funny story about this puzzle.

So for Secret Solver, I was assigned dylanamite. I made my set - SO MANY BEES - and sent it off around Christmas, as I always have. On the 28th, dylanamite messages me asking if I make logic puzzles, which duh of course I do (at this point he does not yet know I made SO MANY BEES). He asked if I had any spare puzzles, and at the time I did not. He said it was fine, but 9 minutes later I sent him this Masyu puzzle. He didn't find out I created SO MANY BEES until weeks later.

Puzzle #485 - 2x2 Masyu

On Puzzlers Club, 2x2 Masyu is a bit of a meme. One of the times it came up I decided to take it a bit less literally - what if you drew a loop of 2x2s instead?

Draw a 2-cell wide loop through some cells and all circles. A black circle must be at a point where the loop turns, the loop must continue for 2 cells in both directions. A white circle must be at a point where the loop does not turn, and the loop must turn immediately on at least one side.

These rules are a bit hard to parse from just a description, so here's an example of 2 things that are the minimal extension from a circle, and 3 things that are not okay.

The black circle on the left contains a turn and extends twice in both directions. The black circle on the top is incorrect because it does not extend two cells from the turn in either direction.
The white circle on the left is correct because it doesn't turn on the circle. The middle white circle is incorrect because it turns on the circle. The rightmost white circle is incorrect because it doesn't turn at the first opportunity on one side.

With that out of the way, here's the puzzle!

Puzzle #484 - Masyu

I made this Masyu puzzle even longer ago than yesterday's Kurodoko puzzle. I originally planned to submit it to GMPuzzles, but between the posting freeze they went on and my own lazily on typesetting it to their format, as well as wanting this puzzle to see the light of day sooner rather than later (ironic, given the 8-9 month delay) I elected to queue it up here.

Puzzle #483 - Just 4 Fun (Kurodoko)

I'm back.

Sorry about the 5 months of inactivity, I had always intended to post my modest backlog of puzzles after Secret Solver (you'll see why) and also wanted to have a small series leading up to puzzle 500. And as part of that leadup, I had wanted to share the puzzles I made for friends who participated in Yajilin Yacht. Yes. That Yajilin Yacht from July/August last year. I kept getting sidetracked but I'd already made the plan and I elected to stick to it, because how long would making 5 more puzzles take? How long would making 3 more take? Apparently, the answer was months and months. Sorry guys, but I did at least get everything out, and now it's time to catch up.

I made this Kurodoko puzzle quite a while ago to show a fun deduction with 4s, and it seems like a pretty good puzzle to start back on.

Puzzle #482 - Pentominous

Thanks to Walker for giving this Pentominous a test-solve! In putting it together I had so many almost working versions that when I finally got to this version, I was only mostly sure of uniqueness. Turns out I did miss a possibility, but fortunately it could still be ruled out reasonably from another approach.

Puzzles #480 & #481 - Heyawakes for the Hike

Heyawake Hike recently concluded on LMI as the 8th daily contest since their revival. The puzzles were made by Sam Cappelman-Lynes and are generally very excellent, I'd highly recommend trying them out. I'd also like to congratulate nishinanntoka for a phenomenal performance as well.

But first, here's a puzzle I made.

This is definitely the sort of design that looks like it would be unfair, but there's some surprisingly neat logic to be found here.

Anyway on the competition - I managed to win! (I recorded a video but halfway through it loses audio for no reason so it's useless)

Just like Nurimisaki Nomad, I made a trophy shaped puzzle to celebrate. Unlike Nurimisaki Nomad, I actually made this before attempting the final puzzle to try to practice a bit. And I basically never practice for competitions - it psyches me out too much to do anything more than solve a couple puzzles to get into a more deduction-focused mental mode.

In other puzzling news, I also crossed 2700 rating on puzzleduel (being the third solver to do this, after Ken Endo and Freddie Hand) and then reached 2738 (and counting???) in the process of clocking the first? 3000 rating full week (Caiji logged 3200+ on the same week but didn't attempt the hardest puzzle) and dominantly winning Doubleshow 7. If this first week of the new year goes well I may reach an astronomical 2750 which would, I believe, be the highest rating peak in the history of the site, done at a time when the competition is fiercer than any past peak. Even if not, I reached 2700 which has been a pipe dream for a long time, considering my peak before October was about 2650. I don't know what happened to me these past few months but something must have clicked.

Puzz.link update!

So, puzz.link updated today to import around 40 new genres from pzprxs! I've made puzzles in a few of these genres before, and took the time to go back and update the old no solution check variant links I had with full links. The penpa links provided still exist and I haven't switched out any of the images, just links. For completions' sake I'm reposting those puzzles below - if you've solved my blog up to this point, you've seen all of these before. If you're going backwards, you'll see all of these in the future.

If you're visiting from puzz.link/db? Hello! Enjoy the puzzles :)
