You’re on the trail of a werewolf that’s been terrorizing your town. After months of detective work, you’ve narrowed your suspects to

one of five people: the mayor, the tailor, the baker, the grocer, or the carpenter. You’ve invited them to dinner

with a simple plan: you’ll slip a square of

a rare werewolf antidote into each of their dinners. Unfortunately, your pet goat

just ate four of the squares, and you only have one left. Luckily, the remaining square is 50 grams, and the minimum effective dose

is 10 grams. If you can precisely divide the

square into fifths you’ll have just enough

antidote for everyone. You’ll have to use a laser-cutting tool

to cut up the square; every other means available to you

isn’t precise enough. There are 8 points that can act

as starting or ending points for each cut. To use the device, you’ll

have to input pairs of points that tell the laser where to begin

and end each cut, and then the laser executes

all the cuts simultaneously. It’s okay to cut the square

into as many pieces as you want, as long as you can group them

into 10 gram portions. But you can’t fold the square

or alter it otherwise, and you only get one shot

at using the laser cutter. The full moon is rising, and in a moment someone

will transform and tear you all apart unless you can cure them first. How can you divide the antidote

into perfect fifths, cure the secret werewolf,

and save everyone? Pause the video now if you want

to figure it out for yourself. Answer in 3 Answer in 2 Answer in 1 When it comes to puzzles that

involve cutting and rearranging, it’s often helpful to actually

take a piece of paper and try cutting it up to see what

you can get. If we cut BF and DH we’d get fourths,

but we need fifths. Maybe there’s a way to shave a bit off

of a quarter to get exactly one fifth. Cutting BE looks good at first,

but that last cut takes a off a quarter of a quarter, leaving us with a portion of 3/16:

just smaller than a fifth, and not enough to cure a werewolf. What if we started with BE instead? That would also give us a quarter. And is there a way to shave

just a bit more off? Both DG and CH look promising. If we make one more cut, from A to F, we may start to notice something. With these four cuts—from B to E,

D to G, F to A, and H to C—we’ve got four triangles and a square in the middle. But the pieces that make

each triangle can also be rearranged to make a square

identical to the middle one. This means that we’ve split

the antidote into perfect fifths! What’s interesting about this

sort of problem is that while it’s possible to solve

it by starting from the geometry, it’s actually easier to start

experimenting and see where that gets you. That wouldn’t be as viable if the square

had, say, 24 cut points, but with just 8 there

are only so many reasonable options. You secretly dose each of the townspeople as the full moon emerges in the sky. And just as you do,

a terrible transformation begins. Then, just as suddenly, it reverses. Your measurements were perfect, and the people and animals of the

town can rest a little easier.

For the second riddle

Take out your scissors and START SHAVING!

Bless the goat, Bless ur brain

Carry on

For the riddle, just dose 4 of them then if it doesn't work you still know who the werewolf is. And in the bonus riddle their are all werewolves.

Easy peasy

Step one : wait until the animated square turns yellow in the video.

Step two:follow the lines because they divide into fifths

SERVE!

You’re serving all the soup from one bowl. Chuck the antidote in the main bowl and serve that in fifths

I’m concerned with the fact that you have that kind of technology in that time period, judging from everyone’s cloths

All are werewolf

… and then you get arrested for putting that in their food

My Answer:

If one of them was a human, why would all the 100 inhabitants say the same thing?

Burn that place, all are werewolves

The solution is actually a proof of pythagrorian theorem

leave the house, come back tomorrow, the remaining person alive is the werewolf

It’s a simple answer,

”NO”.Step 1 : Tell everyone to bring a gun

Step 2 : The person will turn to a werewolf in your house, when this happens, tell everyone to shoot it

Step 3 : Shoot your goat for being a fatty

Ummmm u can just cut every square in half and save the rest for another werewolf attack?

No one .everyone is human

Just cut it into 1/4s. If none of them transform then the one that didn't get the dosage is the werewolf.

Why can’t I grind up the antidote and then using a scale, perfectly measure 10 grams each. EZ PZ!

Please read. Because the statement is “at least one of us i human” we can determine they are all werewolves because if a human is present, then they would be telling the truth which is impossible for the werewolf. We also know they can’t be all humans because the person who got the disease couldn’t have got it by chance without the other inhabitants getting as well.

My idea: cut all edges and u can puzzle afterwards XDD

If someone is only able to lie and another only able to tell the truth ask them something like what is 1 + 1 = ?

It took me forever to figure this out…

Please keep asking riddles

You had me at the pet goat.

I think the answer is A,E C,G B,F and H,D

”the humens always tell the truth"

It can also be cutted 4/5 th is the 1st quarter and so on. Then we got 4 pieces on the upside of every quarters and then automatically we got an inside square. In Which all exactly add to be 1/5 th

Actually you can just dissolve the antidote into the soup. And then separate the soup with antidote into exactly 5 bowls

Bonus: They are all werewolves, a werewolf said that one of us is human if everyone said that, so that is wrong. Thus, there are no humans.

Or you could have just cut 4 lines down and make 5 equal bits. Just saying.

Answer to the puzzle: we know 2 things –

1. Atleast 1 of the 100 people is a werewolf

2. werewolves always lie. And all the 100 people said this "Atleast 1 of us is a human", which means that is a lies which means that there is not a even a single human in the village. So the answer is all the 100 are werewolves.

Like my comment if atleast a single person in this world understands my explanation.

A few ways to easily fix the problem:

Idea 1: Delay the dinner and turn it into a lunch, allowing you time to buy some more antidote off of where you got that later cutter

Idea 2: If you have no time then simply bring some silver bullets and a gun

Idea 3: If you don't want to kill them, then use the laser cutter to dissect your goat

All were werewolfs cause everyone said atleast one of us is a human even the werewolfs in the village said that, it means it is a false statement and all are werewolfs

How many people just guessed it was the carpenter

This is an incredibly contrived set-up for "cut this square into 5 equal groups"

I think that lines AD, AF, EH, EB, CH, CF,GD,GB, might also solve the riddle

Use it once a day or it will explode

This isn’t a riddle

THiS iS a FRiCKeN GeoMeTRy TeST

Answer for bonus riddle: they're all werevolves

Goat Curry for dinner

There are no humans in the village. If there was one or more humans, the humans would be telling the truth. But, the we revolves would also be telling the truth. Therefore it's impossible. So the only other answer is that there are no humans, and all the werewolves are lying.

How come the goat doesn't even overdose from the antidotes?

My solution was to cut the antidote into 4 pieces, feed them to 4 of the suspects and then everyone holds a shotgun at the 5th person who didn't get the anecdote and shoot them if they transform into a werewolf.

Awesome

Or u can cut the cube in 4 pieces, which is really easy using the laster cutter. Then, if no one was cured, you know that the person who got no antidote is the ware wolf

Bonus riddle: call in for a crusade of justice and burn that dark magic werewolf curse tainted village to ashes, you will be even rewarded for that

why don't you just throw the whole cube into the soup pot

-just cut it into 5 strips

– put the whole thing in the pot while cooking it

-smash it into a powder and measure out 10g

-keep your antidote out of reach from goats

Add antidote in soup before serving and here you go

This isn't really a riddle. The werewolf bit is not even neseccary

That's not how laser cutting works.

That's not how biologiy works (every person weighs differently so for every person there's a different effective dose).

100 werewolves

what is with the "at least one of you" thing?

Laser cut them all

Split into 4, tie the Mayor up and get a ransom.

How you do it get some cheese wait for the werewolf to come out and eat the cheese for energy and wrestle the werewolf

Me: (goes to village)

(villigers turn into werewolves)

Me: FML.

Gives antidote to the suspects: nothing happens

You:frik I gave it to the wrong ppl

100 werewolves. Ez

KILL THE GOAT

KILL THE GOAT

KILL THE GOAT

Just dissolve the square into the drink and then split the drink evenly. No need for a laser cutter

you won't be able to think it all through as the full moon is already rising.

Or you cut it in 4, and if no one has been cured you have got the guilty one.

time to put my werewolves of millers hollow knowledge to the test.

it's the mayor, it always is the mayor in that game. If it's not, it's the nervous and suspicious one. Duh

Bonus riddle answer: Everyone is werewolf. As there is at least one werewolf, so when he said 'at least one of us is human' it has to be a lie.

I knew it was the carpenter, he looked just like a werewolf

Or i would cut it into 1/4 and give it to 4 of them, and then the last one i will get a knife and say, "if you transform i will kill you".

You never said they had to survive

What would happen in the bonus riddle if instead of them all saying “At least one of us is human”, they all said “I am not a human.”

If all the humans tell the truth, and all the werewolves lie, then;

The humans would be telling the truth, and would all be werewolves. But then that would mean that they are actually lying, and are not werewolves.

The same for the werewolves. They would be lying, and thus be humans. But would them be telling the truth, and not be human.

Can some smart people in the replies tell me what the outcome would be, or would it just be infinitely fluctuating back and forth?

Here’s a bonus bonus riddle!

You’ve just received word that there is another town with more werewolves! What is it with all these werewolves?

Anyway, you’ve separated the people into 2 groups, (group A and group B) and one group, and only one, is all werewolves, but you don’t know which. Again, all the werewolves lie, and all the humans tell the truth. But for some reason, they’ve all decided they’ll only answer one question per group. What do you ask each group?

I hoped that you'd be more original and make the werewolf someone else than the carpenter

CUT THE SQUARE INTO PIECES

THIS IS MY WEREWOLF CURE

All of them

Plot twist: the goat is the werewolf

Use laser cutter to kill warewolf

For the end riddle, just ask them what color shirt they’re wearing 🤨

IM ONE YEAR LATE

Ask which town you live bruh

Answer: Get more antidote.

Edit: I listened to it again and it said the antidote was “rare.” However, I think that’s bs because the dude had way more than he needed, making me believe it ain’t that rare.

Do a riddle without math PLEASE my brain hurts

“Secret werewolf”

Me: are you sure about that?

Yes everybody in the second riddle are werewolfes, but did you notice that their houses are formed as a pizza slice?

i agree, werewolves lie way too often

Army that we only need 4 squires?

just when i thought it wasnt a math problem this time…

Ten gram > Tangram 😉

i'm actually on a roll today

The goat is the real hero

for the last one you could just ask "what is 1+1?"

Solution: Laser cut all kinds of lines and make squares out of them

solution: watch till the end cause no one is smart enough but the creator to understand the riddle.

Cut in into easy fourths and cook the goat

They are either all human or ww. If one or more were humans, the statement would be true. If they were all human it would also be true.

We know that none of them are wws now, because we got the info from a ww and therefore it's a lie that there is at least 1 ww.

Simple: Just go buy some wolfsbane potion.

Anyone wanna find the solution for me? =)

My solution for the bonus question:

Step 1:Conclude that all of them are werewolves because they are all lying that the village has at least one human.

Step 2: Get some antidote.

Step 3:

CURE THEMJust ask “Is 2 + 2 4?”

If they say no they are werewolves

The baker is obese

why don't you turn the antidote into powder and use scale to weight the perfect 10 grams for each portions? 😶😶

I think all of the villagers ate werewolves

or you can cut the square into 4, since the minimum effective dose is 10 but it never said you couldn’t go over, give the antidote to 4 people, and if none of them turn you know the last one is a werewolf

100 wear wolves and 0 humans because then they all lie and say at least one of us is human

Plot twist: You’re in a hospital bed and you are in a coma imagining all of these riddles, so it doesn’t matter what you do
