Aw this was fun. I got the password right, but I'll be honest, I'm still not entirely sure why my order was correct. But then after reading over jakefriend's comments, I realized there wasn't a guaranteed order or a limit on the number of allowed guesses. So I guess I got it!
@mr_SILLY It's not a game that requires a download--just a simple logic problem. When you've solved it, just enter the answer in the box and it will tell you if you're correct or not. I thought it was a fun little bite size diversion. Pretty easy, but not completely trivial either.
Hint to help you get started: (hopefully you have to hit 'read more' to see this!)
Consider the premise that you should not need to bruteforce the code, at all: The questions, when answered correctly, will only ever lead you to a single possibility of numbers that can be the code.
Then, look at the fifth question first. What would have to be true for this question to indicate a singular numeric answer, between 1-9?
In order for you to get the fourth digit, the fifth question must indicate exactly one number, and only one number. Because it is comparing a sum to itself, the only way it can isolate a single number is at either end of the 1-9 set, if the total of the other three numbers is either less than 2 or greater than 8.
Even-more direct follow-up hint (with one number worked out):
If the first three numbers are all 1 (as low as they can be) and the fifth question is false, then their sum is 3 and the fourth number is either 1 or 2. Because that doesn't isolate a single number, that can't be right - so the fourth number must be 9, with the fifth question being true and the sum of the first three numbers being 8.
From here, the rest of the solving should be a lot easier - there's only so many combinations of the numbers on this phone that can total 8!
Thanks for this! I got the right answer but was a little confused as to why my order was correct. Your comment that "there's only so many combinations of the numbers on this phone that can total 8" set my mind at ease that there isn't a clue necessarily for the correct order, but that a few different guessing attempts are allowed.
So much better for you to solve it yourself but here's the simple logic with no code:
The game basically says that the answers to all 5 questions must be yes or no. There exists a certain series of yes or no for which minimum passwords are available.
I really hope you had to click read more to see this and did not get spoiled but here goes:
To minimise the 10,000 possibilities immediately, knowing the digits immediately removes many possibilities.
If we first assume The first three digits are 1,2,3 then the only possible outcomes are 1237, 1238, and 1239
But that's 3 outcomes so let's try another way. Let's assume first digit is not 1 but second and third are still 2 and 3.
Then there can be 5 possibilites for the first digit being even and 4 being odd(as it is not 1)
Therefore, assume it to be odd to mimimise possibilities.
Let us take first digit as 3, then the first 3 digits are 323 which add up to 8, therefore if the answers to the questions are no,yes,yes,no,yes; the only possible answer is 3239
There is just one way to answer yes or no to all of those questions together, which yields one, and only one, password.
You have to use logic to try and find a way of answering the questions so that the number of passwords that fit all criteria are the minimum possible, you find the right answer when the number of possible passwords is 1 for a given yes or no sequence.
I recommend using a notepad or something to organize the rules and try to make connections between them.
when you think you have the answer, click on "Check solution here" and input what you think is the password.
Thanks, I managed to figure it out after reading your reply. I tried using excel and python to code it all but then found the right answer with just simple logic mentally. Wonderful puzzle!
A lot of comments (from a month ago...) have this assumption that's wrecking things here is that "you can determine the passcode, and that there are no redundant questions" is recursive/contributes to itself - but, in fact, it is NOT one of the hints! The hint answers depend on this rule but, when you have the hints with answers, do NOT consider this rule for determining the code itself from the hints.
Hrm. I've narrowed it down to two possible solutions and I've used all the information and neither of my possible answers are accepted. I've double-checked my work several times and can't see my mistake.
Edit: Ah, I see, the bug in the game has already been found several times. Too bad: it'd be a fantastic puzzle if it wasn't broken.
Edit edit: Nope, I'm wrong, found the flaw in my logic, see below.
I think I'm going to sleep on this before I start working my way through all the rot13 text to see if anyone has an answer. Is there a rot13 plugin for Firefox? There must be.
If anyone wants to be generous and check my work, here's the clearest way I can find to write out my chain of logic: what am I missing?

njvrzm, I've been enjoying the discussion here, and I've just written a little solver for this puzzle. Now I'm curious if you consider this updated puzzle broken as well:
I've forgotten my 4 digit passcode!
Fortunately, I saved some hints on my phone. All the hints have a yes/no answer. I remember that if you know all the answers then you can determine the passcode.
The hints are:
Is the first digit smaller than the second digit?
Is the second digit smaller than the third digit?
Is the third digit smaller than 4?
Is the first digit even?
Is the fourth digit smaller than the sum of the first two digits?
Unfortunately, to access the answers to the hints, I need to log in to my phone with my passcode :(
(Notes: There's no information about redundancy of the hints. Also, this puzzle has a unique solution)
no, it could be 3209, 3219, 3229, 5219, or 5209 without the 3rd questions being a yes, and 3039, 3139, or 5039 without the 2nd question being a yes. They have multiple possible codes, so you know those answers arent correct
how do i get to the input password screen after solving? After I solved it i wanna go back to that screen but the 'check solution here' link leads straight to the congrats screen
idk how to figure this out, if hint one is yes then hint 4 is no, same way other way around, the only problem is that i have no way to know wich of the two is correct, the last hint is also useless, the fourth digit could be anything. maybe im just stupid lol
Focus on the fact that if you know all of the answers, you can figure out the password. this means that the 2nd digit and 3rd digit has to be 2 and 3, as if it wasn't the solution wouldn't be restricted to one solution. after that, focus on the fifth hint. with logical reasoning, you should be able to figure it out. remember, you have to narrow it down to ONE solution.
I remember that if you know all the answers then you can determine the passcode, and that there are no redundant questions.
This means that if you knew the yes/no answers to each of the 5 hints, then only a single 4-digit passcode would satisfy all five of the hint answers. Additionally, it means that if you removed any one of the hints, then there would be multiple 4-digit passcodes that would satisfy all four of the remaining hint answers.
To get you started, think about the combination of hints 1 and 4. If the answer to hint 1 is "Yes", is hint 4 redundant? If the answer to hint 4 is "Yes", is hint 1 redundant?
Don't know how to write in this cryptic style like some others do, but I am pretty sure I found a list of answers and can determine an unambiguous passcode from them, but this one isn't accepted. I can see the numbers in the cryptic texts, that would be included in my code.
No answer should should render a question unnecessary. Think about what information each question gives you. Some questions would render others irrelevant if you answered them in a particular way
Very cool idea and a creative take on the detective genre!

Nice puzzle! I am curious about the “there are no redundant questions” part, I don’t think the puzzle would become logically ambiguous or unsolvable if that information wasn’t given, but am I missing something?
Sadly I’m stuck at the point where I’m trying to figure out how to actually play the game. I can’t find a download link. Perhaps it’s hidden somewhere? It doesn’t appear to be a browser game either: when I click on the picture, all I get is a larger version. Curious!
I was a bit disappointed that there's no further puzzle once I entered the solution haha. Would be fun to get some flavor text of what the unlocked phone is like too. Still, an interesting puzzle! I haven't seen anything like this one before and was stumped for a good ten minutes.
Liked it! A good narrative wrapper to put around a logic puzzle of this kind. I've seen these tricks used before, but it's always remarkable to me that you can find one specific 4 digit number from what seems to be so little information. Also, I expected "check solution" to show me the solution, clever idea having it require me to enter the password!

In order for you to get the fourth digit, the fifth question must indicate exactly one number, and only one number. Because it is comparing a sum to itself, the only way it can isolate a single number is at either end of the 1-9 set, if the total of the other three numbers is either less than 2 or greater than 8.
Even more direct hint in next comment.
Even-more direct follow-up hint (with one number worked out):
If the first three numbers are all 1 (as low as they can be) and the fifth question is false, then their sum is 3 and the fourth number is either 1 or 2. Because that doesn't isolate a single number, that can't be right - so the fourth number must be 9, with the fifth question being true and the sum of the first three numbers being 8.
From here, the rest of the solving should be a lot easier - there's only so many combinations of the numbers on this phone that can total 8!
Thanks for this! I got the right answer but was a little confused as to why my order was correct. Your comment that "there's only so many combinations of the numbers on this phone that can total 8" set my mind at ease that there isn't a clue necessarily for the correct order, but that a few different guessing attempts are allowed.
Does it spell a word?
So much better for you to solve it yourself but here's the simple logic with no code:
The game basically says that the answers to all 5 questions must be yes or no. There exists a certain series of yes or no for which minimum passwords are available.

Let us take first digit as 3, then the first 3 digits are 323 which add up to 8, therefore if the answers to the questions are no,yes,yes,no,yes; the only possible answer is 3239
Can someone please explain this, do not understand the question. People in the comments are writing such strange texts
There is just one way to answer yes or no to all of those questions together, which yields one, and only one, password.
You have to use logic to try and find a way of answering the questions so that the number of passwords that fit all criteria are the minimum possible, you find the right answer when the number of possible passwords is 1 for a given yes or no sequence.
I recommend using a notepad or something to organize the rules and try to make connections between them.

Thanks, I managed to figure it out after reading your reply. I tried using excel and python to code it all but then found the right answer with just simple logic mentally. Wonderful puzzle!

Oh so every letter was shifted by a certain number of characters? That's cool to know, thank you! Wjy are they doing that though? For privacy?
I Don't Know. But, probably for privacy.
A lot of comments (from a month ago...) have this assumption that's wrecking things here is that "you can determine the passcode, and that there are no redundant questions" is recursive/contributes to itself - but, in fact, it is NOT one of the hints! The hint answers depend on this rule but, when you have the hints with answers, do NOT consider this rule for determining the code itself from the hints.
This is a fun little puzzle!
Very fun little game! It was great applying the logic and now I wanna try the original board game lol

njvrzm, I've been enjoying the discussion here, and I've just written a little solver for this puzzle. Now I'm curious if you consider this updated puzzle broken as well:
I've forgotten my 4 digit passcode!
Fortunately, I saved some hints on my phone. All the hints have a yes/no answer. I remember that if you know all the answers then you can determine the passcode.
The hints are:
Unfortunately, to access the answers to the hints, I need to log in to my phone with my passcode :(
(Notes: There's no information about redundancy of the hints. Also, this puzzle has a unique solution)
no, it could be 3209, 3219, 3229, 5219, or 5209 without the 3rd questions being a yes, and 3039, 3139, or 5039 without the 2nd question being a yes. They have multiple possible codes, so you know those answers arent correct
how do i get to the input password screen after solving? After I solved it i wanna go back to that screen but the 'check solution here' link leads straight to the congrats screen
You can open the link in incognito mode, so it does not access your cookie.
i cant play??? there is no game how did you guys play it
ooo you need to click on 'check solution'
idk how to figure this out, if hint one is yes then hint 4 is no, same way other way around, the only problem is that i have no way to know wich of the two is correct, the last hint is also useless, the fourth digit could be anything. maybe im just stupid lol
i guess i just have to try it 6561 times and see wich one fits
Focus on the fact that if you know all of the answers, you can figure out the password. this means that the 2nd digit and 3rd digit has to be 2 and 3, as if it wasn't the solution wouldn't be restricted to one solution. after that, focus on the fifth hint. with logical reasoning, you should be able to figure it out. remember, you have to narrow it down to ONE solution.
This was fun! Would be curious to see what the "proper" steps were... my solve feels kinda big and clunky.
how am i supposed to find out the passcode if i d ont have the answers to the hints...
This is the key part of the instructions:
This means that if you knew the yes/no answers to each of the 5 hints, then only a single 4-digit passcode would satisfy all five of the hint answers. Additionally, it means that if you removed any one of the hints, then there would be multiple 4-digit passcodes that would satisfy all four of the remaining hint answers.
To get you started, think about the combination of hints 1 and 4. If the answer to hint 1 is "Yes", is hint 4 redundant? If the answer to hint 4 is "Yes", is hint 1 redundant?
nvm i give up i used all my math brain power (this is literally probably so easy and im so very stupid) 
OHHH
I figured
how do i play 🏳🌈
Don't know how to write in this cryptic style like some others do, but I am pretty sure I found a list of answers and can determine an unambiguous passcode from them, but this one isn't accepted. I can see the numbers in the cryptic texts, that would be included in my code.
Hmmm, I can think of one thing you might be missing.
Not sure what this hint is implying. Redundant in relation to what?
Very cool idea and a creative take on the detective genre!

>Both satisfy the conditions of the puzzle
The winning condition is to have an answer set that implies a unique solution. Both of your suggested answer sets allow for multiple pin numbers:

I'm not sure I know what you're getting at because:
>But if the first digit is 3, the second must be 2
Why?
>So now we've fixed an answer set (no, no, yes, no, yes) that leaves us with exactly one pin number: five zero three nine.
This is not correct, because with (no, no, yes, no, yes) the pin 3039 would also be valid, so five zero three nine is not a unique solution.
Nice puzzle! I am curious about the “there are no redundant questions” part, I don’t think the puzzle would become logically ambiguous or unsolvable if that information wasn’t given, but am I missing something?

I love games like this!
Sadly I’m stuck at the point where I’m trying to figure out how to actually play the game. I can’t find a download link. Perhaps it’s hidden somewhere? It doesn’t appear to be a browser game either: when I click on the picture, all I get is a larger version. Curious!
It’s a puzzle wrapped in another puzzle…
There's no download link! The description is the game.
I was a bit disappointed that there's no further puzzle once I entered the solution haha. Would be fun to get some flavor text of what the unlocked phone is like too. Still, an interesting puzzle! I haven't seen anything like this one before and was stumped for a good ten minutes.
Liked it! A good narrative wrapper to put around a logic puzzle of this kind. I've seen these tricks used before, but it's always remarkable to me that you can find one specific 4 digit number from what seems to be so little information. Also, I expected "check solution" to show me the solution, clever idea having it require me to enter the password!
