# 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.

Hints:

• 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).

# Puzzle 45 / Fillomino [No-Path]

As requested, a puzzle post! Straight from the WTF-variant department. Quite hard.

This is a Fillomino, with the additional constraint that for each polyomino, there must not exist a path (i.e. a sequence of cells, each orthogonally adjacent to the next) that includes each of the polyomino’s cells exactly once (and does not include cells outside the polyomino).

As a degenerate case, 1-ominoes are banned as well.

# Puzzle 43 / Fillomino [Nonrectangular + Walls]

I’m extremely satisfied — a little incredulous, in fact — with how this puzzle came out. chaotic_iak labels it the “most ridiculous fillomino ever in history”. Apparently, it’s rather tricky.

ETA: Journalistic responsibility compels me to mention that chaotic_iak also added, “might be beaten later”. Oops?

This is a Fillomino combining the Nonrectangular (polyominoes can’t be rectangles) and Walls (polyominoes can’t span thick lines) variant rules. I think the first variant first came from mathgrant; I’m not as sure about the second, but they both appeared in Fillomino-Fillia 2, at least.

Write a number in every empty cell so that every group of cells with the same number that is connected through its edges is a shape that’s not a rectangle with that number of cells. In addition, cells separated by a thick border may not contain the same number.

# Puzzle 42 / Fillomino [Greater-Than]

Oops, I forgot the “puzzles” category was semi-reserved for puzzles I constructed/wrote, because among other things an LMI bot is following it. Anyway, if this makes up for anything, I have a puzzle that I’ve procrastinated posting for very, very long.

This is a Fillomino puzzle. Inequality signs in the grid must be satisfied by the two numbers they touch.

# Puzzle 40 / Fillomino [Samurai]

Yeah, and there’s this. chaotic_iak rejected this variant for his February sequence in order to get consistent 7×7 dimensions, so I made one. It’s been about a month. I have no idea why I procrastinated posting it until now.

This is a Samurai Fillomino, which means each grid satisfies the constraints on its own. Write a number in every empty cell so that, in each square grid, every group of cells with the same number that is connected through its edges has that number of cells. Note that the two grids must contain the same numbers where they overlap, but the grouping should be considered independently. I’d explain this really carefully if it weren’t the main gimmick of this puzzle.

Wow: if you type `7x7` without code tags, WordPress autoreplaces the x with a multiplication sign. That’s cool. How do people think of things like this?

# Puzzle 36 / Fillomino [LITS]

mathgrant’s hybrid type: 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.

This is from the “constructed and procrastinated forever before posting” pile.

My current code base still works, but I’m beginning to realize how horrible it is — it’s not just the mock-function-objects. Time to learn Scala and rewrite from scratch!
