A man unties you in a dank, grody room. He pulls out a chair and asks you some personal questions. He then offers you a choice:

Stay in this room for the rest of your life, or take a chance on your life to leave. He also releases a cage full of arthropods. You take the later choice.

He tells you:

You have some choices. You can go into 1 of 5 rooms. Each of them will have a sign, and you get to choose which one will NOT kill you.

You walk into the hallway and see:

DOOR 1: Could door 5 be lie? You might as well try?

DOOR 2: Numbers three and five might keep you safe, but door 1 will lead to death.

DOOR 3: Door 1 is quite lie, certainly to bring demise.

DOOR 4: Do you believe that three could say such things, such lies will not keep you safe.

DOOR 5:That is wrong door four, a number in it's prime will serve just fine.

Which door do you choose? Will you live? Will you die?

Door 5 says to not trust a door in "it's [sic] prime". If we interpret that as saying we shouldn't trust door with primes numbers, then we shouldn't trust Door 5, since 5 is prime. Door 1 seems to endorse Door 5, and Door 3 seems to endorse Door 1, and Door 2 seems to endorse Door 3, so that leaves Door 4.

But that requires a lot of inference leaps of logic. I think this puzzle is rather poor, as there isn't really a basis in the clues themselves to come to a conclusion; only by assuming that a solution is intended, and that the solution given above is the closest to a logically supported one, can we infer that this is the intended solution.

    $\begingroup$ Door 5 presents us with a liar paradox so I'm not convinced you can then make valid deductions at all. $\endgroup$ Sep 7, 2020 at 5:05
  • $\begingroup$ So we're supposed to choose the door which neither deprecates itself nor suggests that a different door is the one? How are we supposed to be able to determine that from the puzzle? $\endgroup$ Sep 7, 2020 at 17:31
  • $\begingroup$ Cite door 5. It has to do with math. I will edit it to make it a tad less confusing. $\endgroup$ Sep 7, 2020 at 17:38

I propose that the answer is

door 5.

This is simply because

door 1 says that "door 5 holds a key," implying that that's the door that will lead to freedom.

After all, we may assume that

all of the doors are truthful, since the things they say don't contradict each other or anything else we know.

  • $\begingroup$ Not quite, try using what door five says instead. $\endgroup$ Sep 7, 2020 at 17:38
