Puzzle 49 / Triple Back

I’m not really satisfied with the execution, but eh, what the hell. My brain can only function at so much of its full capacity when it’s a few kilometers up in the sky.

This is a Triple Back, variant on MellowMelon’s Double Back. Briefly, draw a closed loop through all square centers visiting each bold-outlined area exactly three (= ⌊π⌋) times. Shaded cells do not influence solving, only aesthetics.


Thanks for being an awesome place to live. ❤

(Yes, I know I’ve been posting way too many puzzles and way too few text posts recently. Expect that to change soon.)

November 2015 Puzzles Hints

  • A Signature Puzzle: Trying to solve the puzzle with Extreme Speed can’t hurt.
  • Anticron: This puzzle runs on two distinct 24-hour clocks, which is why you can be zoned out for half the time and still solve it.
  • When Is My Birthday Again?: Apparently, if you don’t want to tell your friends your birthday, you can tell one of them the month and the other the day. And if you really want to annoy them, you can change one of the days at the end so they have to work it out again.
  • Three for the Price of One: How do you get nine entries in the word bank from three puzzles? If you’re stuck at the start or the end, check near or between the corners.

Puzzle 48 / Double Back

At least one person wants me to post. I’m not even going to try do a life summary. It’s too hard. Let’s just say:

  1. right now, my blog drafts contain a backlog of ~7500 words and counting;
  2. I was not accepted as an MIT Admissions blogger, which is bad because my blogging will continue to not reach a large audience, but good because my blogging will continue to not reach a large audience. Maybe it had something to do with the fact that, because the application form wouldn’t let me submit without any media, I panickedly cranked out the following puzzle in an hour or so to attach.

This is a MellowMelon’s Double Back. Briefly, draw a closed loop through all square centers visiting each bold-outlined area twice. Shaded cells do not influence solving, only aesthetics.


Throwback Thursday Puzzles!

Wow, there are so many cool things in my old folder. I could probably create and schedule enough filler posts to make my streak last through my week-long trip and back. I guess I won’t, though, because I don’t want to dilute my textwall-draft brand more than necessary and there are a few text posts that I fully intend to post before leaving. Or at least one. Although on second thought, it’s possible they might actually not be as interesting as posts like this one about the adorable me from the past. As Pablo Picasso once said, “Youth has no age.” (Yes, I totally just went on BrainyQuote and searched for “youth”. Forgive me, please.) Oh well.

Today’s throwback theme is old puzzles! Particularly picture ones! In reverse chronological order by last modified time, because I said so! All the image puzzles are puzzlehunty in the sense that you’re supposed to end up with a single word or short phrase as your final answer.

A straightforward one to start. I have no idea what’s with the filename, though.

haxxor/purity2/logic.html (2010/10/10?)

My file hierarchy is really weird. I don’t think this time stamp is when I wrote the puzzle because it was part of a silly static site setup I created (but never actually put anywhere), and I probably edited and regenerated stuff like the breadcrumbs many times, but it’ll have to do.

This is also funny because the title of the HTML file is “Logic Puzzles” and the description starts, “These puzzles were made when I was really bored…”, but there’s only one puzzle.

Well, it’s better than an under construction page, I guess.

I’ll quote the entirety of the old instructions as I wrote them, even though they’re really verbose, since it’s easy to scroll past them:

Puzzle 47 / Fillomino [LITS + Walls]

CLICKBAIT PERSONALITY TEST THAT YOU CAN DO WITHOUT SOLVING THE PUZZLE: What do you see in the puzzle image below? I have my own thoughts but I won’t bias you by posting them yet. Sound out your thoughts in the comments below! (I don’t expect this to work but I’d love to be proven wrong)

Okay so apparently how puzzles work is I go nearly a year without posting one and then when I post a terrible one, I feel guilty and obligated to post a legitimate one soon after. Testsolved by chaotic_iak.

This is a Fillomino (write a number in every empty cell so that every group of cells with the same number that is connected through its edges has that number of cells) where each tetromino has had their 4s replaced by one of L, I, T, or S describing their shape, and they obey the rules of LITS — they can touch if they are not congruent, they must all be connected, and their squares cannot form a 2×2 block. In addition, cells separated by a thick border may not contain the same number or letter.

See my Puzzle 36 or chao’s Puzzle 36 (I only noticed this coincidence today, it’s quite amazing) or FFF 6 for prior LITS Fillominoes and links to more, and my puzzle 43 for a prior Fillomino Walls mutant with links to other Walls.


Puzzle 46 / Fillomino [LITS + Extra Region + Walls + Anti-Walls + Inequality + Tapa + Masyu]

5:27 PM phenomist: do you use gridderface to make pretty puzzles?

5:52 PM phenomist: actually nvm excel is probably easier lol

Okay I’m sorry this is a horrible puzzle where the rules don’t make sense and I didn’t even get it testsolved. I just wanted an image to concisely demonstrate the capabilities of gridderface, my puzzle marking and creation program, for the project homepage, after somebody expressed interest in using the program to write a puzzle. Then I got tremendously carried away.



  • L, I, T, S are comparable, but not in that order.
  • The Tapa clue isn’t part of any polyomino.
  • The Masyu clue restricts the borders around three intersections, including itself.
  • (Is there a name for Fillominoes with the opposite of walls?)

Other than that, you’ll have to figure out the rules yourself (partly because I am lazy and partly because if I listed the rules it would probably take longer to read and understand them than to apply them to the puzzle…)

Anyway, this post is actually to say that it is now possible to use the Scala reboot of gridderface without spending forever to attempt to install Scala, because I figured out how to make .jar file releases. It’s probably still hard to use but who knows?

Because it’s a full rewrite, the version is back to 0.2 unlike the old 0.5. As I noted earlier, the code base was horrible.

By the way here is the Heyawake phenomist eventually made.

Okay back to homework (and agonizing over which college to go to).
