Ask either bird: "Will the other bird tell me that the door on the left leads to heaven?"
If the door on the left goes to heaven:
The truthful bird will say no, because the lying bird will say no.
The lying bird will say no, because he knows the other bird (the truth one) will say yes.
In other words, ask that question to either bird about either door, and if the answer is no, that is the door to heaven.
No wild assumptions about souls or double questions and other dumb bull**** that this thread is full of. Just 100% logic, problem solved.

Godslayer Mode Attempt #2
"Is it true that you will tell me this door goes to Heaven?"
If the bird says "Yes", pick the door you are referencing. If the bird says "No", pick the other door.
How It Works
Scenario 1 - I Ask Honest Bird, Referencing Heaven Door
It is true that the honest bird will tell me the Heaven door is the Heaven door. His response will be "Yes, it is true."
Scenario 2 - I Ask Lying Bird, Referencing Heaven Door
It is not true that the lying bird will tell me the Heaven door is the Heaven door - he would tell me it is Hell. Since it is not true, the lying bird will say "Yes, it is true."
Scenario 3 - I Ask Honest Bird, Referencing Hell Door
It is not true that the honest bird will tell me the Hell door is the Heaven door - he would tell me it is Hell. Since it is not true, the honest bird will say, "No, it is not true."
Scenario 4 - I Ask Lying Bird, Referencing Hell Door
It is true that the lying bird will tell me the Hell door is the Heaven door, because it is a lie. Since it is true, the lying bird will say, "No, it is not true" which is a lie.Last edited by stoker6913; 04-10-2012 at 12:10 PM.

That there's some sound logic boy. I think you got it.
You explained it a bit awkwardly though, some people might think you are assuming that the one bird is a good one or a bad one, which isn't the case.
Basically, the honest bird will tell you the straight truth either way, and by asking the question "Is it true that you will tell me this door goes to heaven" you are making the dishonest bird double lie, thus tell the truth.

god slayer mode:
"which door do you deserve to go to?"
because it is said the bird that lies is bad (and to lie is a sin, so hell, but he will tell you heaven) and the one that tells the truth is good so the riddle says, so whichever door the bird tells you, you go to.

Don't know if anyone solved all of these yet. Here are my long and perhaps over-complicated attempts, but they appear to work.
Here is my solution to Easy Mode and God Mode:
I choose a bird and ask, "Would you say 'yes' if I asked you whether the left door is the door to heaven?"
1. Either the bird says "yes" or the bird says "no."
2. If the bird says "yes," there are two possibilities: either the bird is telling the truth, or the bird is lying. If the bird is telling the truth, then the left door is heaven (because he's truthfully saying he'd truthfully say "yes" if I asked him if it is). If the bird is lying, then when he answers my question with "yes," that means he would actually say "no" if I asked him whether the left door is heaven. But since he always lies, that answer of "no" would also be a lie, which means that the left door actually is heaven. So, the left door is heaven if the bird answers "yes."
3. If the bird says "no," there are again two possibilities: either the bird is telling the truth, or the bird is lying. If the bird is telling the truth, then the right door is heaven (because he's truthfully saying he'd truthfully say "no" about the left door). If the bird is lying, then when he answers my question with "no," that means he would actually say "yes" if I asked him whether the left door is heaven. But since he always lies, that answer would also be a lie, which means that the right door is heaven. So, the right door is heaven if the bird answers "no."
4. So, if the bird says "yes," the left door is heaven. If the bird says "no," the right door is heaven. There you go.
Here is my solution to God Slayer Mode:
I choose a bird and ask, "Is the following disjunction true: either (i) you are a lying bird and the right door is heaven or (ii) you are a truth-telling bird and the left door is heaven?"
1. Either the bird says "yes" or the bird says "no."
2. If the bird says "yes," there are two possibilities: he is either telling the truth or lying. If he is telling the truth, then the disjunction I asked about is true: either (i) he is the lying bird and the right door is heaven or (ii) he is the truth-telling bird and the left door is heaven. But since he is telling the truth in this scenario, it must be that he is the truth-telling bird and the left door is heaven (the other disjunct is false because he is not the lying bird). On the other hand, if he is lying, then the disjunction I asked about is false. That means that it is false that he is the truth-telling bird and the left door is heaven, and it is false that he is the lying bird and the right door is heaven. But since he is lying to me in this scenario, he is the lying bird, so the only way for it to be false that he is the lying bird and the right door is heaven is for it to be false that the right door is heaven. So, the left door is heaven in this scenario, too. Thus, if the bird says "yes" to my question, the left door is heaven.
3. If the bird says "no," there are again two possibilities: he is either telling the truth or lying. If he is telling the truth, then the disjunction I asked about is false. So, it is false that he is the truth-telling bird and the left door is heaven, and it is also false that he is the lying bird and the right door is heaven. But since he is telling me the truth in this scenario, he is the truth-telling bird, and so the only way for it to be false that he is the truth-telling bird and the left door is heaven is for it to be false that the left door is heaven. So, the right door must be heaven. On the other hand, if he is lying, then the disjunction I asked about is true (since the bird lyingly said it is not), so it is true that: either (i) he is the lying bird and the right door is heaven or (ii) he is the truth-telling bird and the left door is heaven. But he is lying to me in this scenario, so he isn't the truth-telling bird, so the second part can't be true. So, it must be that he is the lying bird and the right door is heaven. So, if the bird says "no" to my question, the right door is heaven.
4. So, if the bird says "yes," the left door is heaven. If the bird says "no," the right door is heaven.

Cliffs:
To solve Easy Mode and God Mode, ask, "Would you say 'yes' if I asked you whether the left door is the door to heaven?"
-If "yes," then either lying or telling the truth. If telling the truth, then they'd truthfully say "yes" to left door, so left door is heaven. If lying, then they'd actually say "no" to left door question, but that would also be a lie (since they always lie), so the left door is heaven.
-If "no," then either lying or telling the truth. If telling the truth, then they'd truthfully say "no" to left door, so right door is heaven. If lying, then they'd actually say "yes" to left door question, but that would also be a lie, so the right door is heaven.
-So, if the answer is "yes," you know the door to choose (left); if the answer is "no," you know the door to choose (right). Solved with one question.
-----
To solve God Slayer Mode, ask, "Is is true that either (i) you are a lying bird and the right door is heaven or (ii) you are a truth-telling bird and the left door is heaven?"
-If "yes," either lying or telling the truth. If telling the truth, he is not the lying bird, so (i) can't be true; so (ii) must be, so the left door is heaven. If lying, then both (i) and (ii) are actually false; and since the bird lied, he is the lying bird, so the only way for (i) to actually be false is for the right door to not be heaven, so the left door must be. So, if "yes," the left door is heaven.
-If "no," either lying or telling the truth. If telling the truth, then both (i) and (ii) are false; but since the bird is telling the truth, the only way (ii) can be false is for the left door to not be heaven, so the right door must be heaven. If lying, then either (i) or (ii) (or both) must actually be true; but this bird is lying, so (ii) can't be true since he's not the truth-telling bird, so (i) must be, which means that the right door is heaven. So, if "no," the right door is heaven.
-So, if "yes," left door is heaven. If "no," right door is heaven. Solved with one non-hypothetical question.Last edited by MaximosJ; 04-10-2012 at 03:20 PM. Reason: formatting
