imo 2012 problem 6 (25): This. Basically the idea is inducting with step 12 (12n+1 \rightarrow 12n+13, 12n+5 \rightarrow 12n+17, 12n+9 \rightarrow 12n+21, 4n+1 \rightarrow 4n+2).

hidato (15): My only Hidato published in this blog at least for now. Probably more coming later, but it’s hard to find something new. Maybe this puzzle pack by MellowMelon suffices?

fillomino (13): Yes I make many Fillomino puzzles. Subscribe to my blog 😛

Also a few that intrigues me:

fillomino solver (4): Fillomino is NP-complete by reduction to 3SAT. And while computer-generated Fillomino are easy (then why would you need to find solvers for them?), handmade Fillomino are hard for computer if not using heuristics. I don’t think one exists out there yet.

numerical puzzle in math 6 by 100 square (3): Wait what? Grammatically confusing for me. If you want a 6×100 puzzle though I can arrange it.

videos on how to yajilin (1): I don’t have it, although I can make some guide. Also searching Yajilin in YouTube gives this…what? Seriously.

give a formal proof that the kenken puzzle below has exactly one solution. (1): Needs the puzzle.

This post is written from my Android phone.

I’m scheduling this to be up at 20 November 2012, 12.00, of whatever time zone this WordPress for Android app uses (probably UTC+7, but let’s see). Let’s see when WordPress posts this to my Twitter. Recent scheduled posts had the tweets delayed by 1h 20m and 20m respectively.

UPDATE: 0m? Meh.

Puzzles 34-35: It’s Now Regiothmetics Class!

New genre! Regiothmetics Yajilin. I need a good name for “Regiothmetics”.

Follow usual Yajilin rules (draw a loop and shade all the remaining non-given cells black; black cells may not be adjacent). In addition, there are two types of clues:
– Blue, no sign, size-12: The number indicates the number of black cells in the region plus in the line of sight (from the arrow following the direction of the arrow up to the edge of the grid). Black cells that are in both the region and the line of sight are counted twice.
– Brown, sign (+ or -), size-10: The number indicates the number of black cells in the region minus in the line of sight (from the arrow following the direction of the arrow up to the edge of the grid). Black cells that are in both the region and the line of sight cancel each other.

Everybody! It’s the beginning of Regiothmetics class! To become a genius like me, do your best!
Our class begins, with a simple medium 7×7 puzzle,
If you’re done and you still want to be more genius like me, try this easy-medium 10×10 puzzle!
But wait! Did I just reverse the difficulty?
The answer is, the answer is, I didn’t, I didn’t, that’s because, that’s because,
The smaller is indeed the harder one!

Puzzle 35: Regiothmetics Class! Assignment 2!
Regiothmetics Yajilin

UPDATE (20-Nov-2012, 18.36 UTC+7): Fixed Puzzle 34 (R7C1 to make it solvable) and replaced Puzzle 35 (the former is utterly broken).

If you are one of the top three, you get extra points!

But seriously. I offer this thing again. Be one of the first three people to submit the correct solutions to both grids, and you get a puzzle as a gift. You can choose the genre and stuffs like that.

Yes, even if you’re colorblind you should be able to distinguish non-signed givens and signed givens. And their sizes differ by 2 points. Should be sufficient. Although when I add more clue types (possible seeing recent Surveyors Heyawake) I need more non-color cues.

Yay. Did I say today (and yesterday) is one of my most productive blogging and puzzling days ever?

Blog productivity rises to an all-time high

Yeah. I can even think of the genres for Puzzles 34-35. I might also clean up my blog (remove unused categories, add tags, etc).

Anyway. Recap of things.

I recently played BANG!. The game was pretty insane 😛 But I liked it. And Wikipedia has an article for it. Cool.

Also, I recently played Monopoly Deal. A bit of stupid imbalanced stuffs (seems like too much luck), but a good idea for a card game.

Even another one. I recently played Trump and Rummy, two card games using the standard French deck. They are said to originate from Indonesia. Really? If curious and want to compare, ask me about the rules.

Yay. Card games ftw.

What If

What ifs… Always a great thing to escape from reality. Which itself is not a pretty good thing unless you have nothing to do, like laying on your bed and waiting when sleep will strike you. Indeed I wrote this while laying on bed, waiting to fall asleep.

After last night’s dream of transforming to a furry anthro, I spent a good deal of my thinking to twist it just so slightly so that I would transform to a Skymin anthro if it continued. Then the thought stayed with me for the whole day. I looked or felt my back at least three times for no real reason (itchy or something) today; all of which were checking whether the dream would became a reality by my back starting to grow white fur and such. (Obviously it didn’t.)

Afterwards, whenever I laid on my bed (which is twice: before nap and before sleep), when I didn’t actively using my phone such as browsing TVTropes, making a fic about game worlds meshed together, and writing a blog post, my thoughts would always run to that.

What if I’m truly becoming a Skymin anthro?

I tried to think a few normal routines, only that I was a Skymin anthro doing the routines. Among several, I got that:
– I would need way more shampoo for my fur.
– I would have some problems with personal documents (I specifically thought of passports, but identity cards worked too).
– I thought I might need some other people to be transformed to some other Pokemon anthros too. It would make things more fun, although not necessary.
– I would have problems using my touchscreen phone. I didn’t think fur-covered fingers can send some sort of “onFingerDown” signal to touchscreens…
– I would have looked odd. Not because of the Skymin look, but because I wore glasses. Skymin wearing glasses is weird.

But of course there are positive things too. Only that they are pretty obvious (people look at me in awe(?) and I can fly for example). Yeah.

What if I have a Skymin pet?
Seriously, this one is pretty hilarious. Bringing the Skymin to school.

Today (Monday) I have a math test. This post should be up at the time I’m having the math test anyway. In any case, here’s roughly what’s imagined, translated:
Teacher: But you can’t keep your pet while test.
Me: I can’t get him to wait outside!
Teacher: But he can help you otherwise!
Me: Seriously? Not intending to brag, but I definitely don’t need his help. I can do the test myself.
Teacher: …
Me: …and I promise Sky (his name) won’t want to cheat anyway.

Described pretty much exactly as imagined, so sorry if you got offended. But yeah.

Also, I held him with one hand while riding a motorcycle (okay I can’t phrase this properly, but there is someone who rode the motorcycle and I sat on the back), and wind rushed through his fur. Cute fluffy ball with a kawaii smile, if you ask. Yes, seriously. Can’t describe it without “girly” words. Meh.

What if I get asleep now?
Maybe it’s a good idea. Scheduled away.

Puzzle 33: Nope, There’s Totally Nothing Odd Here

Fillomino Warp. Note the orange squares? They act as teleporters. So R2C3, the square above the top-left orange square, is connected to R9C8, the square below the bottom-right orange square, since one can “walk” downward from R2C3 to the orange square, gets teleported, and continues walking downward to R9C8. Similarly, R3C2 is connected to R8C7, R4C3 is connected to R7C8, and R3C4 is connected to R8C7. Note that the orange square itself is not actually a square and cannot have a number. Otherwise follow Fillomino rules.

“The teleportation machine is now complete. With this, one can warp anything from one of the machines to the other.”
“Are you sure it’s safe?”
“Yes, totally.”
“Nothing buggy?”
“None at all.”
“Make a Fillocity with some buildings warped around?”
“That’s…hell.”
“But that will be fun! I promise.”
“Okay whatever. Just make sure nothing goes odd.”

Yes, nothing goes odd. Literally…maybe. Complete the plan. Rated easy-medium.

Puzzle 33: Nope, There’s Totally Nothing Odd Here
Warp Fillomino

Gift to Yoshiap, whose recent Cipher Fillomino is a pretty great piece. You should check his blog out, or at least that particular puzzle. As the prize of solving Puzzle 25, he wanted a Fillomino with an unusual twist. He suggested a Fillomino where each number can only appear in one region (aka all identical numbers must be in a region), but that has been done, sort of.

This one is also a proof of concept. Almost. I tried to play with the 2s at the opening, covering an edge of an orange square to limit the options of some other 2 in the neighborhood of the other orange square, but apparently I didn’t quite get it right. But this one is pretty satisfactory (logically; aesthetically it certainly reaches my standards). Maybe next time I play with Warp Fillomino, I’ll try to make some fun tricks. Or maybe you remember my old piece about a Fillomino put on the surface of a cube? That’s aesthetically pleasing, but if I remember correctly, the tricks are usual for a normal Fillomino. I think I need holes instead of simply several grids connected together somehow to do something fun.

Finally, it’s only one week towards my semester exams. You might not see puzzles for a few days. I’d cap it at 14, but since I’m not a good promise holder, I won’t promise anything. Although maybe non-puzzle posts appear once in a while.

Puzzle 32: Two New Recruits

Surveyors Heyawake, now with additional two types of clues and a change in rules. Read.

Shade some cells black such that:
– No two black cells are orthogonally adjacent
– All white cells form a single polyomino
– No line of contiguous white cells span over 2 or more room borders (thick borders)

Additionally, there are two types of clues: in-grid and out-grid. (Names in brackets tell the name of the clues. Yes, they are now canonized.)
– In-grid clues may refer to the number of black squares in the room (region bordered by thick border) (Heyawake) or the number of black squares in the 3×3 square centered at the square containing the clue (Minesweeper). There can be at most 1 Heyawake clue in a region.
– Out-grid clues may refer to the number of black squares in the row/column (Tents) or the length of some line of maximum contiguous white cells in the row/column (Freedom). There can be at most 1 Tents clue in a row/column.

By maximum contiguous white cells I mean that it cannot be extended; it’s bounded by either the grid’s boundary or some black cell.

Note that it’s possible for a region to have clues but none of them are Heyawake, and for a row/column to have clues but none of them are Tents.

As the popularity of the surveyor job skyrockets, new positions appear. As reported in the headlines, two new positions that work from outside the complex are now available; one reports the number of obstructions in the line of sight and the other reports one of the freedoms instead. As usual, they mix together, making it pretty much impossible to tell them apart.

Your task stays the same. Our surveyors have done their jobs dutifully; now your task is to reveal the traps. Rated medium-hard.

Puzzle 32: Two New Recruits
Surveyors Heyawake v2

A gift for David Millar (thegriddle.net), as the second person to complete Puzzle 25 (linked above). He wanted Surveyors Heyawake with a new twist. I added several (depending on how you define a “twist”). Enjoy!

The next puzzle (okay, one of Puzzle 33-35) will be the gift to the third solver. Yes, Puzzle 25’s offer has ended. Time to make a new offer 😛

Dreams

Constantly getting memorable ones. Apparently I always dreamed whenever I’m sleeping in some time period of 6-8 AM; my most recent dream was in my 6-7 AM sleep (woke up for a while at 6 AM, then fell asleep again).

The dreams were bizzare, and for whatever reason sometimes they stayed in my mind for the day. More if I actually store the dream (write it somewhere).

Yesterday, my dream was really weird. Aspertia City became a gigantic metropolitan city with skyscrapers literally everywhere, more than Castelia City. Exiting it via the ground went to some volcanic cave that currently hosted some ritual. Flashbacks occurred. While in my flashback, I woke up 😛

Today’s is not that insane; I’d say this one is pleasant, even. Participating in some competition; math, I think. But that’s not the point. The point is that I was turning to some furry anthro. My back had grown fur and somewhat softening, although I don’t remember seeing some transformation anywhere else in my body. To what, I’m not sure, but I certainly hoping for Skymin 😛

Bizzare stuffs.

On a loosely related note, you should have known that I turned 17 last Friday (not two days ago, the week before that). I had fun and made three wishes that I would unlikely get but would surely be surprised if I did get them. The wishes are, in increasing order of unlikeliness, get a Skymin plushie, get a real Skymin (yes, the Pokemon), and be a real Skymin. Guess what…

The first wish, get a Skymin plushie, is somewhat fulfilled. I got a Skymin action figure as a gift from my friend that I was sure hadn’t seen the wishes. I now have a Pokemon collectible, which is a Skymin. What a joy 😀

A gift from my friend. Yes, it’s truly a Shaymin action figure.

As you can also see, my third wish occurred somewhat in today’s dream, turning to a furry anthro. Which anthro, I’m not sure; I couldn’t see my back. But let’s take the best case; Skymin. Then my third wish was half-complete.

Gotta dream about being totally transformed; whatever the result is (whether I can speak, walk like a normal person but fly like a normal Skymin, do telepathy, etc). Hm…

Puzzle 31: Hey People Redux

Akari. Put light bulbs. A light bulb illuminates unobstructed white cells in the four cardinal directions (up, down, left, right). A light bulb may not be illuminated by another light bulb. A number means that there are that many light bulbs in the four cells orthogonally adjacent to that cell.

Because Yoshi is bored, he decides to make a blog and post puzzles in it. However, his first puzzle is aesthetically unpleasant, so this Shaymin decides to fix it a bit… “Rated medium!” the Shaymin exclaims.

Puzzle 31: Hey People Redux
Akari

Employing a very unusual opening allows this puzzle to have both great aesthetics (intended) and a tough-looking puzzle (not intended). Well, good luck. Bifurcation (aka trial-and-error) will easily destroy this apart, but can you get that cool opening?

Puzzle 30: Mini Legendaries, Maxi Pranks

Our six mini legendaries (Mew, Celebi, Jirachi, Manaphy, Shaymin, Victini) have mastered the art of transforming. Each of these six legendaries decided to trick Arceus, transforming to the others for the five work days. Since Arceus doesn’t have good logic (Uxie holds it), it asks you for help. Can you help the God of Pokemon tackling this medium mishap?

Basic facts:
1. There are six mini legendaries: Mew, Celebi, Jirachi, Manaphy, Shaymin, Victini.
2. There are five work days: Monday, Tuesday, Wednesday, Thursday, and Friday, in that order from earliest to latest. Each of the work days are separated by a day; that is, Tuesday is 1 day after Monday, Wednesday is 2 days before Friday, and so on.
3. In each work day, each legendary transforms to exactly one of themselves. A legendary may “transform” to itself. No legendary may appear twice; that is, no two legendaries may both transform to the same legendary in the same day.

The puzzle:
1. Each legendary transform to five different legendaries in the week.
2. Mew and Celebi have a disagreement, and as the result, neither transforms to the other in the first three days.
3. Celebi blames the disagreement to Shaymin, and as the result, neither Mew nor Shaymin transforms to the other in the last two days.
4. On Tuesday, no legendary transforms to itself. On Thursday and Friday, each of exactly two legendaries transform to themselves. On Monday and Wednesday, exactly one legendary transforms to itself.
5. Manaphy transforms to Shaymin in some day and to Jirachi in another day. The difference between these two days is 4 days.
6. Shaymin never transforms to the legendary which never transforms to Shaymin.
7. Victini transforms to Jirachi, and Jirachi transforms to Manaphy. Both take place on Monday.
8. Shaymin transforms to Mew in some day.
9. None of Mew, Celebi, and Jirachi transforms to any of Manaphy, Shaymin, and Victini on Wednesday.

Well, good luck? It’s not that hard.

So I haven’t made one large puzzle for Puzzle 30; I can’t think of a genre. So here’s a word puzzle. I hope you know English.

I need to make more of these to practice my construction skills.
