Here is a little puzzle/story I wrote up that is based on another famous puzzle, but just stated in a slightly funner, more vivid fashion:


A zombie outbreak occurs. People who are infected with the zombie virus present with eyes that have veiny, green lines and will turn into full blown zombies one week after initial symptoms occur. The mechanism of infection is still unknown. Those that have already become zombies hate their own appearance and because of it, destroy/disrupt everything that is reflective. Because of this, no one knows for sure whether or not they are infected.

You wake up in a confused haze. Despite your trepidation, you stumble out doors in search of food and other uninfected humans. The city you once loved looks like a war zone: abandoned vehicles and small fires ravage the streets. Amidst the chaos, you find a locked laboratory building with a digital display in front of the door. On the display, it says, "PEARL LABORATORIES INC. In this laboratory there is a cure to the zombie virus. To gain access, you must successfully complete an extensive battery of logical tests and puzzles to demonstrate you are intelligent and deserving of vaccination. Furthermore, you will have to shoot and kill an infected person who is not yet a zombie to demonstrate your drive to survive." Although you have no idea if you are infected or not, you want access to the lab just in case. You complete the onslaught of logical exams and kill an innocent infected human you find down the street out of your own selfishness.

The lab doors open. You walk in and see five other people who apparently arrived in the lab not long before you have. All their eyes shot with muddy green veins. One is a female with blond hair that reminds you of... wait. Did I have a wife? I can't even remember. There is a red button in an opaque case in the lab. A laser pans down from the ceiling to the floor, scanning your bodies. "Infection detected" you hear a computer generated voice say. I wonder if I'm infected.... An announcement comes through some speakers. "At least one of you in the room has been infected with the zombie virus. Anyone who presses the red button will immediately be injected with anti-zombie alpha, the first of two necessary components to cure the virus. If you do not have the zombie virus, anti-zombie alpha will kill you. There is enough anti-zombie alpha for everyone, however there are less than six units of anti-zombie beta remaining. An alarm on the button with sound for a minute once per hour, signalling that it is available to be pushed. You are all being monitored. Physical violence against other potential patients will disqualify you from vaccination."

You look at the other people in the lab. You know they are infected, but you don't know if you yourself are. You know they are extremely powerful at logical deduction and selfish to have gained access to the lab as you have. Because of the limited supply of anti-zombie beta, you don't want the others to know if they are infected or not, and they will not tell you if you are infected or not.

Two minutes pass as you all intently stare and analyze one another. The button begins to flash.

What happens next?

its all balls or not balls my friend. I hit the button.
 
So this lab has no glass or reflective surgical steel? What kind of lab is this?
 
Ok so the first step is closing my eyes. Since eyes are reflective. They gouge eachother's eye's out and disqualify themselves. From there, I pick up an eyeball. If I have the urge to step on it, I must be infected so I press the button. It doesn't qualify as physical violence since the eye has already been removed. Problem solved.

"Mechanism of infection is still unknown."

Also, if you somehow displayed that you were attempting to be infected by a person, they would know they're infected, decreasing your chance of getting anti-zombie beta. though that's not a bad way to convince a hottie to give you a blowie in a zombie apocalypse :D
 
so this is based on the riddle with the king and the red dots

True. I solved it though with some edits.
 
4get dat. logical solution would be to board up the mall with a shotgun & stay in till the end of times

& then maybe modify some buses just 4 kicks
 
I'm confused. If at least 5 people are infected and there is enough anti venom to cure 6, what's the problem?

theres 6 ppl including u. theres (less than 6) only 5 anti zombie beta

Gotcha.

I suppose you could start asking one by one, starting with you, if it's good to press the button. They will say no to you either way (infected or not), then you ask about the second guy, and if they say no, it means that you are infected.

Edit: Are we supposing they answer questions?
 
Now I gotta weight 'till the TS comes back so I can get closure? There's no logic in that.

If you weren't infected, wouldn't the first guy consider saying yes so you die? Why is it always no? Why does the 2nd person's answer vary while the 1st person's doesn't? Why would two "nos" be definitive? I don't entirely understand your process.

He has no reason to want me to die if I wasn't infected, because the math adds up. He's looking at 4 infected and 1 non infected, so even if he were infected that's 5. Venom for all.

And if I was infected, he's in the same boat we are, looking at 5 infected, so he would tell me "no" cause he's unsure.

But what if he's an asshole?

Then we curse him as we die.

I think these sort of tests are supposed to have everyone acting logical, so arbitrary answers wouldn't make sense. Also, everyone would be in agreement.

So I get the first part about always saying no, but why would the 2nd"no" guarantee you're infected? Couldn't it also mean that you're fine?

If you weren't infected, they have no reason to lie to him. If they lie to him and tell him not to press it, it means they're all looking at 5 infected people (including you). Which means everyone is infected and you press the button.

I don't know if that's right, but that's all I got.
 
Another solution could be to try to trick one of them into DQ'ing themselves and then nobody has reason to lie anymore.
