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?).

Puzzle 40: Sky’s Revenge

Liar Slitherlink. Follow regular Slitherlink clues (make a loop following the gridlines that doesn’t touch/cross itself anywhere, and givens tell the number of sides used around that cell). However, exactly one given in each row/column is wrong. The task of determining which givens are lying is given to you.

It was a tough journey, but Sky made it to Odd Island. He was pretty surprised to see a few zeroes; perhaps the zeroes betrayed Even Island inhabitants? In any case, he managed to avoid suspicions, and in case someone attacked him (he’s #492, so yeah), he simply Seed Flared them away.

He made it to the prison that he suspects to hold many of the twos, and boy, what a surprise! No less than 86 twos are present. They sure kidnapped a lot of twos! He wanted to free them all from those pesky guards, but he surely could not Seed Flare those innocent twos. So he went with a very unusual approach…of Liar Slitherlink-ing them.

Wait… Isn’t Sky’s previous puzzle a Liar Slitherlink? Is Sky our hero? Hm…

Puzzle 40: Sky's Revenge Liar Slitherlink

Puzzle 40: Sky’s Revenge
Liar Slitherlink

Yes, MellowMelon-inspired. Although I don’t think he made that for the purpose of maximizing the number of 2s; mine started with a grid of 2s and givens got replaced when they don’t fit.

Also, if you’ve solved the grid, you may continue the story:

Sky’s bizarre strategy worked! Somehow. The guards were disoriented by being called liars and stuffs, and they all went arguing, allowing those twos to escape. They all went back, Sky was reunited with his lost two, and he could finally make another puzzle involving twos. Maybe next time…

Puzzle 39: Where Are My Twos?!

Liar Slitherlink. Follow regular Slitherlink clues (make a loop following the gridlines that doesn’t touch/cross itself anywhere, and givens tell the number of sides used around that cell). However, exactly one given in each row/column is wrong. The task of determining which givens are lying is given to you.

BREAKING NEWS: Leader of Flygrass Town lost his twos; police are looking at possible suspects
“It was all there when I went to sleep last night, but I found them missing this morning!” Sky cried.

That was two days ago. Now Sky has gotten over his loss, and he wants a revenge. “I’ll show them what I can do even without those 2s!” Sky adamantly proclaimed. After leaving this medium puzzle, he leaves to the Odd Island, the most probable suspect of where the 2s are kept hostage in.

Puzzle 39: Where Are My Twos?! Liar Slitherlink

Liar Slitherlink

Yes, no 2 at all. Stay tuned for the second part (and also the final part) of Sky’s mini-adventure of reclaiming his 2s!

Puzzle 38: Fillomino Party! Part Finale!

Kropki Fillomino. Follow regular Fillomino rules. In addition, Kropki clues appear on the grid. If two numbers are separated by a black circle, then one is double of the other. If two numbers are separated by a white circle, then they are consecutive integers. Note that if there is no circle, then it doesn’t mean that the two cells have none of the two relationships (double or consecutive). Between 1 and 2, either circle may appear.

And we’re finally on the last puzzle! It’s apparently a genre invented by…er…let me see.
*skims*
*skims further*
*doesn’t skim further* Okay, sorry. Apparently this is the chef’s original, or it should be so since the chef was too lazy— err, failed to find any other puzzle of the same variant. Anyway, enjoy our last medium meal…
…wait, Chef! Why is it another medium?!
Uhm anyway, enjoy this one, and see you in the next party!

Puzzle 38: Fillomino Party! Part Finale!
Kropki Fillomino

Uh wait. Chef, is this lower-right part is truly empty?
…uh, no answer. My chef likes to escape from questions. Anyway, I suppose that means yes.

Yes indeed. Have fun with this final puzzle! I’m off to study for finals. Don’t expect too much until, say, a few days after 3 December? My last finals will be on 3 December. Non-puzzle posting will probably resume as usual depending on whether I get something to post.

Puzzle 37: Fillomino Party! Part 2!

Greater-Than Fillomino. Follow usual Fillomino rules. In addition, inequality signs appear on the grid. Given inequalities must be satisfied by the numbers in the corresponding cells. Try MellowMelon’s too if you don’t get the rules.

So, you’re satisfied with the first meal? You’re not done yet.
This one is a puzzle, which genre is inspired from some yellowish fruit. A melon perhaps? Although I’m not sure how a melon can make puzzles. Or is it a Melon-pult? *shudders*
Umm, anyway. Enjoy. Another medium meal. Hey chef, is there going to be any heavy meal or something?

Puzzle 37: Fillomino Party! Part 2!
Greater-Than Fillomino

Part 2 of the party. One more to go. This theme of no number at all should have been done somewhere. (After an educated guess and a look on it, the original Fillomino Fillia has it.) Yay. Stay tuned for the last in the batch…let’s take a guess on the variant, shall we?

Puzzle 36: Fillomino Party! Part 1!

LITS Fillomino. Follow usual Fillomino rules. However, there can be no number 4 in the grid; all 4-minoes are replaced by L,I,T,S shapes. All LITS shapes must form a single connected polyomino, no two identical LITS shapes may be adjacent (including after rotation and/or reflection), and no 2×2 region may be completely used by LITS shapes. Basically a cross between Fillomino and LITS that’s invented by mathgrant.

Welcome to my Fillomino party! I’m Shaymin, your host. I’m not sure why I get to host this while some polyomino can be chosen instead, but whatever.
So… You will be served three Fillomino puzzles. To avoid getting too full, we will serve each puzzle 12 hours after the previous, so you will get a 24-hour party. Neat!
Here’s your first puzzle. I heard that this genre is invented by some foxy animal, although I’m sure he’s not a Vulpix or something. Seriously, I can’t recall any Pokemon which is fox-like and is cyan…err, wait, he’s not a Pokemon? Okay then.
This one should be a medium meal. After all, you have 12 hours to digest it before your second meal.

Puzzle 36: Fillomino Party! Part 1!
LITS Fillomino

Yes. Fillomino party. Over the next 24 hours, you will be presented a total of 3 Fillomino puzzles…or probably variants.

This one is a gift for betaveros, for solving Puzzles 34-35. Two spots left! No, the other two puzzles aren’t gifts for Puzzles 34-35 solvers.

Finals in 3 days. Why am I still making puzzles? Sigh.

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?

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 😛

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?
