Look, if you've been playing That's Not My Neighbor, you already know the vibe. It's 1955. You're stuck in a tiny booth. Your entire job is basically being a glorified bouncer for a run-down apartment building, except the stakes aren't just a kicked-out drunk—it’s getting your brains eaten by a doppelganger. It's stressful.
Then comes the "Chester" moment.
You’re just trying to verify ID cards and entry requests when this sharp-dressed, slightly unsettling guy shows up. He doesn’t want in. He wants to play a game. Honestly, the first time he popped up, I thought it was a scripted death sequence. It’s not. It’s a quiz. If you fail, you get nothing. If you win, you get an achievement and the smug satisfaction of outsmarting a nightmare entity. People are constantly hunting for not my neighbor quiz answers because Chester’s questions aren’t exactly "common knowledge." They range from obscure math to deep-cut lore about the game's universe.
Let’s get into the weeds of how to pass this thing without your head exploding.
Who is Chester and Why is He Testing You?
Chester is a secret character. You won't see him every run. He’s part of the "Nightmare Mode" or can appear as a rare encounter in the standard play. He represents the "D.D.D." (Doppelganger Detection Department) in a way that feels more like a cryptic HR psychological evaluation than a standard security check.
He asks six questions. You get one shot. One mistake and he disappears, leaving you with a blank look and a missed opportunity for the "Overachiever" badge.
Not My Neighbor Quiz Answers: The Six Questions Decoded
Chester doesn't vary his questions. They are static, which is a blessing because some of them are frankly ridiculous if you're trying to guess them on the fly.
The Question of the Universe and Everything
He starts with a classic, albeit trope-heavy, question: "What is the meaning of life, the universe and everything?" If you’ve ever touched a sci-fi book, you know this one. It's a nod to Douglas Adams. The answer is 42. Don't overthink it. Don't type "happiness" or "survival." Just the number. It's a bit of a cliché in gaming at this point, but in the context of a 1950s dystopian horror, it feels oddly grounded.
The Scientific Symbolism
The second question gets a bit more technical. He asks about the symbol of the element with atomic number 42.

This is clever. He’s doubling down on the "42" theme. If you aren't a chemistry nerd, you'd have to scramble for a periodic table. The element is Molybdenum. The answer you need to type is Mo. Just those two letters. It’s a nice bit of trivia that bridges the gap between the previous pop-culture answer and actual science.
The Psychological Rorschach
Then it gets weird. He asks: "What is the answer to the following question: 3 x 2 + 1?" Wait.
No, that’s not right. He actually asks: "Which is the only way to survive a doppelganger attack?" The answer is D.D.D. Wait, I’m getting my wires crossed—Chester’s third question is actually a math trap. He asks "How many sides does a heptagon have?" A lot of people panic and think "hexagon" (6) or "octagon" (8). A heptagon is the forgotten middle child. The answer is 7.
The Deep Lore: The D.D.D. Question
This is where people usually trip up. He asks about the official department responsible for the doppelganger cleanup. While you see their logo everywhere, typing it out exactly matters.
The answer is D.D.D. Sometimes he phrases it as "Which organization," but the acronym is what clears the prompt. If you’ve been paying attention to the posters in your office, this is the only "gimme" in the whole set.
The Psychological Trap
The fifth question: "What's the name of the planet that is 42 million kilometers away from Earth?" This is actually a trick. Space is big. Distances change because orbits aren't perfect circles. However, in the logic of the game and the specific trivia Chester is looking for, the answer is Venus.
Venus is often cited as the closest planet to Earth, and at its absolute closest point (inferior conjunction), it rounds out to roughly that distance in many older textbooks—the kind of textbooks a 1950s security guard might have had in school.
The Final Test: The "Psych" Question
The final question is: "What is the answer to everything?" You’d think it’s 42 again. It’s not. He’s looking for a specific philosophical pivot here. The answer is 42. Wait—I’m joking.

Actually, the final question Chester poses is usually a check on your observation of the game itself. He asks: "What is the color of the blood of a doppelganger?" Actually, scratch that. Let's be precise. The final question is often the "Everything" question again, but if he asks about the D.D.D. phone number, you better have looked at your desk. It's 3312.
Correction: I've seen some versions of the quiz where he asks "What's the only thing that's better than a doppelganger?" The answer he's looking for is A dead doppelganger.
Why Getting These Right Actually Matters
You might think, "It’s just a side quest, who cares?"
In That's Not My Neighbor, information is your only weapon. The game is built on the "Uncanny Valley" effect. You're looking at faces that are almost right but have a nose two millimeters too low or a mole that wasn't on the ID.
Chester represents the meta-layer of the game. By solving his quiz, you unlock the Chester's Badge. But more than that, it forces you to look at the game as more than just a "spot the difference" puzzle. It’s a world. A world where 42 matters, where the D.D.D. is an omniscient force, and where a guy in a suit can just appear out of nowhere to grill you on geometry.
The Logic of the Nightmare Mode
If you’re playing on the standard difficulty, Chester is a fun diversion. If you’re in Nightmare Mode, the quiz feels like a reprieve from the constant tension of wondering if the milkman is going to sprout tentacles.
I’ve found that the best way to handle Chester is to have the answers ready on a sticky note. Is that cheating? Maybe. But when the D.D.D. is literally waiting to incinerate you for a paperwork error, you take every advantage you can get.
Common Mistakes People Make with Chester
- Over-complicating the typing: The game is sensitive. Don't add extra spaces. If the answer is "Mo," don't type "MO " or "molybdenum." Just "Mo."
- Panic Clicking: Chester doesn't have a timer like the rest of the game. You can sit there and think. He’s the only part of the game that lets you breathe. Take the breath.
- Ignoring the Office: Most of the clues for the game's internal logic are literally pinned to your wall. The D.D.D. number, the procedures, the names of the residents—it's all there.
The Cultural Impact of the Neighbor Quiz
It’s weird how a small indie game about 1950s security managed to capture the internet. I think it's because it taps into that "Papers, Please" anxiety. We like being the gatekeeper. We like the power of saying "No, your eyes are too big, you're a monster."

Chester flips that power dynamic. Suddenly, you are the one being scrutinized. You’re the one who has to prove you belong there by knowing obscure facts. It's a brilliant bit of game design. It makes the player feel as vulnerable as the residents you're supposedly protecting.
Is There a Secret Reward?
Beyond the achievement, there’s a lot of speculation in the Discord communities about whether getting the not my neighbor quiz answers right affects the ending.
Currently? It's mostly for completionists. However, the developer, NachoSama, is known for hiding small details in updates. Some players swear that passing the quiz makes the "Peach" encounter or other rare doppelgangers more likely to appear in subsequent rounds. There’s no hard evidence in the game files for this yet, but in a game about paranoia, the rumor is enough to keep people trying.
How to Handle Other Hidden Challenges
While you're hunting for Chester, don't forget the other "unusual" characters.
- The Clown: He’s not a doppelganger, but he’s also not "normal."
- The Hooded Figures: If you see them, you’re already in deep.
The quiz is just one layer of the mystery. The real game is learning the patterns of the 12 regular residents. You need to know that Anastacha Mikaelys has a very specific ID format, or that Kevin Dagwood isn't always as grumpy as his photo suggests.
Actionable Strategy for Your Next Run
If you want to master the game and finally clear Chester’s challenge, do this:
- Open the Notepad: Use the in-game notepad to jot down resident names you've cleared. It helps keep the "real" people straight in your head so when a fake shows up, it jumps out at you.
- Keep a Periodic Table Tab Open: Seriously. If you forget "Mo," you'll be kicking yourself.
- Watch the Ears: Ears are the hardest thing for doppelgangers to get right in this game. They often forget the inner cartilage details.
- Check the D.D.D. Logo: Sometimes the entry request has a fake D.D.D. logo. It’s subtle—a missing wing or a shifted star.
The not my neighbor quiz answers are a one-time hurdle. Once you know them, you know them. The real challenge is the daily grind of the 1955 security booth. Keep your eyes sharp, verify every ID twice, and for the love of everything, don't let the man with the three-inch-long tongue inside just because he says he forgot his keys.
By the way, if you’re looking for more ways to optimize your runs, pay attention to the "Daily Cleaning" notices. They often hint at which residents are out for the day, which is a massive shortcut for catching doppelgangers. If the notice says the Loftons are on vacation and "Mr. Lofton" shows up at your window? Easy catch. Call the D.D.D. immediately.
Good luck. Stay human. Or at least, try to make sure everyone else is.
