Puzzle 46: Black, Black Everywhere

Kropki Fillomino. Follow regular Fillomino rules. In addition, Kropki circles appear, although not necessarily all. Click above for better rules.

UPDATE 02-Jan-2013: Blargh. First, a non-unique puzzle with unknown amount of solutions. Second, a non-unique puzzle with 11 solutions. I hope I managed to reduce the number of solutions in the second puzzle by 90.91% with the addition of a circle.

Medium-hard, after erring twice. Blargh.

End of World

It’s like this:

stream = open(“World.txt”);
isEOF(stream) {
output “End of World(.txt)”;
}

Seriously though. I’m absolutely sure the world won’t end…I think I should say the world didn’t end. The winter solstice is said to be a minute ago since this post (18.12 UTC+7, 06.12 AM EST), so if you happen to read this post, the prediction has been refuted successfully.

In a very unrelated context, someone wants to draw some sketches to be included in the story-like puzzle pack? I can’t pay though, so only accept this if you’re really bored without any work-in-progresses and you decide to go to a random puzzler’s blog.

Special Puzzle 8: It’s Erased

Domino Nurikabe. Follow regular Nurikabe rules (color some cells black so black cells form a single polyomino and white cells form separate polyominoes (islands) so each island contains exactly one number which represents its size). In addition, the black cells must be able to be partitioned into non-overlapping dominoes. Question mark represents an unknown number.

Sky woke up. “Darn, I shouldn’t make puzzles that late. What, I think it was 1 AM or something when I fell asleep…”
He reviewed his puzzle, and noticed something was smudged. “Err, what’s the number in this cell supposed to be?”
“Hey Sky! Has the puzzle been made?” someone shouted from outside, shocking him.
“Oh ya right! Just a little fix!” Sky rushed to find the number in the erased cell, but he couldn’t get the actual number. Hesitantly, he erased the smudge, put a question mark in it, and gave it to his senior that leads The Daily Puzzle, otherwise known as Chaos at the Sky.
“Domino Nurikabe, with an unknown number. Seems legit. Let’s see,” and the boss, chaotic_iak, left. Sky returned to his home sadly.

Lots of Puzzles!

Okay, so I’m committing myself into two puzzle projects.

First, a puzzle test in LMI. I won’t tell further, but e-mail me if you’re interested as a test solver. I need about one or two more.

Second, a puzzle pack. Well, there will be two; one is from the puzzle test, much like MellowMelon’s FF2 pack. Should be a sufficient amount of puzzles from every genre that makes an appearance in the test so you can enjoy any genre in a hopefully suitable difficulty.

The other is different. The premise is a story related to my OCs, one of which has been revealed in a previous post, and it will also feature several more OCs of another furry puzzle maker. Puzzles will accompany the story. Let’s say it takes place in some location with a bunch of puzzles scattered, and it takes the usual hero-vs-villain theme, but let’s see.

I haven’t typed a single word to the story; I haven’t made any puzzle for it; I haven’t planned the plot with more details… Mostly focusing to the LMI test and the upcoming tryouts for national exams, the latter can probably make me unavailable for four months, and afterwards I still need to manage college stuffs. But hey. I think I made a puzzle while a teacher was explaining in class anyway…

So yeah. Most obvious rejects will come to this blog often, but better puzzles will be kept for those two events.

Puzzle 45: Which Way

Yajilin+. Follow regular Yajilin rules (draw a loop on cells’ centers and shade the unvisited non-given squares black so no two black squares share an edge; clues show the number of black cells in the given direction). But the directions of the arrows are unknown; it’s one of the given two directions. (The other direction may or may not have the given number of black squares.)

Sometimes there seems like not enough clues to solve a mystery, but it solves cleanly anyway. Sky has tried to construct such mystery, and apparently he’s satisfied with this easy-medium brainteaser… Need to put even less clues.

It might be very early to tell this, but stay tuned for May 2013.

Puzzle 44, Special Puzzles 6-7: Insane Mind Comes Again

EDIT in 2017 because someone tried solving these: in Special Puzzle 6, row 7, the right clues should say ? 5 (the 5 is to the right) instead of ? ?.

Puzzle 44: Outside Fillomino. Follow regular Fillomino rules. In addition, each of the number outside describes the content of some cell inside that is of distance at most 4 from the edge (for example, a clue above C1 points to some cell in R1C1-R4C1, and a clue below C1 points to some cell in R7C1-R10C1). No two clues point to the same cell, and the clues are read in order (the clue that is two squares above C1 points to a cell earlier than the cell that the clue that is one square above C1 points to). Yeah weird rules; I’ll attach an example if necessary.

Special Puzzle 6: Outside Fillomino. Exactly the same rules as above, only that question marks represent numbers (not necessarily all identical or all different) which are all less than 10.

Special Puzzle 7: Cipher Kropki. Fill in the squares with numbers between 1-6 such that each number appears exactly once in each row/column. If and only if two orthogonally adjacent numbers differ by 1, there is a white circle between them. If and only if the ratio two orthogonally adjacent numbers is 2 in some order (the larger is twice the smaller), there is a black circle between them. Either circle can appear between consecutive 1 and 2. If no circle appears, then neither of the two conditions above apply. Count the solutions.

When your mind goes wild, these are the results… And yes, this is the only line of the “story”. Medium for Puzzle 44 and Special Puzzle 6, medium-hard for Special Puzzle 7.

Blah.

In other news, it seems that the element(s) that manage the images are broken (see previous puzzle). I’m trying to get them fixed. (EDIT: Seems like alt property of a elements hates line breaks. Manual edit on each image to remove the alt property solves the problem.)

EDIT: Whoo so I apparently forgot that Special Puzzle 6 has been posted before. This post will then have Special Puzzles 7-8. Too much care on numberings 😛

Puzzle 43: Sum vs Product

Corral Antisymmetric Multiplicative. Follow regular Corral clues (draw a loop following grid lines so all numbers are inside the loop). For each clue, let h be the number of cells that belong in the loop, all in the same row, all connected, and contains this clue’s square. Define v similarly for cells in the same column. For each pair of symmetric clues (with respect to center), exactly one of them gives h+v-1; the other gives hv.

…so I can’t think up a story. I shouldn’t be typing this while Russia vs Macau is going in osu! World Cup 3Easy-medium puzzle.

UPDATE (9-Dec-2012, 20:06): Fixed ambiguity in bottom middle.

Enjoy. No particular comment.

Heavily Linguistical Mind

TOEFL iBT score of 103/120, enjoy reading about grammar constructs (not the formal grammar which is math-related although I like it too), and just thought of the word “impromptu” when I wanted to type this entry (which after googling “define impromptu” gives the meaning similar to unplanned, a perfect adjective for this entry). Yay.

I’m also a sesquipedalian, and I just searched the meaning of “hippopotomonstrosesquipedalian”. Apparently it’s an adjective applied to long words, while sesquipedalian is a noun describing either long words or people using long words. Meh hippopotomonstro- prefix is weird.

Puzzles 41-42: Untruthful People

Puzzle 41: Liar Hidato. Follow regular Hidato rules (fill each white cell by a number between 1-66 inclusive so each number appears exactly once and consecutive numbers are adjacent (orthogonally or diagonally)). In addition, for every row/column that has at least a given, one of the givens is lying.

Puzzle 42: Liar Akari. Follow regular Akari rules (put some lamps which lit the entire unobstructed (by grid edges or black cells) paths to up+down+left+right of each so all squares are lit and no lamp lights another, and numbers on black cells represent the number of lamps orthogonally adjacent to the corresponding black cell). In addition, all givens are lying.

It has never been the case that people in Flygrass Town are lying en masse, but it never removes the possibility. Indeed, today is perhaps the “Lying Day” where people are basically lying all the time. Almost.

In the Allgreen Forest, guards are sometimes lying. Fortunately, no two lying guards can be in the same line of sight, as either will report the other and hell will break loose. But still, the visitors of the forest are confounded. After several reports, Sky decides to fix this by putting a correct traversal path. If he can.

Meanwhile, in the Art Museum, a blackout occurs. But it’s Lying Day, so no guard gives the correct response when they are queried about the number of lights they guard. Apparently they all conspired to answer zero? Whatever, Sky still gets to handle it.

Enjoy these very unusual Liar variations. It will probably be a long time before I get around these things again.

Why Liar Akari’s black squares are much lighter? I suspect that you will write the correct given for each cell…maybe. But it’s better to prepare too much than too little. If you want a version with darker black squares, just comment; I’ll provide one if there is enough interest (say, 2 people?).
