7 Games Like That's Not My Neighbor (Free, No Download)
Neighbor made a door check scary: the fear is a decision, not a chase. Seven free browser games in that orbit, with the controls each one lists.
Key takeaways
- This list rounds up seven free browser games that share That's Not My Neighbor's "verification horror" premise: someone is at your door, and you have to decide.
- Only one pick runs the same loop: Night Shift at Block 13 — night guard, apartment block, visitors who may not be who they claim.
- Two are Among Us-style social deduction rather than door-checkers: Who Is Imposter and Stickman Imposter.
- Two carry the imposter name without the imposter game: Imposter Mission is a pixel platformer and Imposter Galaxy Killer is a line-drawing puzzle.
- On a phone, Imposter Galaxy Killer is the cleanest fit — it is drawn with a finger — and Imposter Duck: Online is the one listing that states its touch joystick outright.
What makes the "doppelganger formula" work
Before the list, it's worth naming what Neighbor actually built: verification horror. You're handed a position of small authority — doorman, night guard, watchman — and a routine job. The dread arrives through tiny wrongness rather than a chase: a smile held half a second too long, an ID photo where the mole moved. It scales down well, which is why it survives on browser hardware, and why the games below can all run in a tab.
What we actually found
We opened all seven embeds and read the control notes and the description each listing ships, and the honest answer is that this list is looser than its title suggests. Only Night Shift at Block 13 is doing Neighbor's job: WASD to move, mouse to look, E to inspect a passport or a journal, and a green button to admit versus a red one to turn away, across seven nights. Everything else is a neighbour of the genre rather than a copy of it. Two of the seven are Among Us-derived social deduction, with crew tasks, emergency meetings and an airlock vote. Two others borrow the word "imposter" for games that are not deduction at all: Imposter Mission is a pixel platformer where you swap between knight, wizard and ranger, and Imposter Galaxy Killer is a line-drawing puzzle. What is left is a conversation game and a camera game. If you came for the door, read the first entry and Five Nights at Freddy's; the middle of this list is for people who want the paranoia rather than the paperwork.
Controls split the list differently from how it reads. Four of the seven are keyboard games: Night Shift (WASD, mouse look, E to inspect, two buttons for admit or deny), Diner in the Storm (left click to interact, A and D to walk, space to advance dialogue), Who Is Imposter and Stickman Imposter (arrow keys). Three carry a touch flag. Two of those say so in the controls they list — Imposter Mission ("tap or use arrows") and Imposter Galaxy Killer ("draw a line", which is a finger gesture by design) — while Five Nights at Freddy's is flagged for touch but lists a mouse and nothing else, so treat its mobile build as unconfirmed here. Of the two extras below, Imposter Duck: Online is the one that spells it out: WASD or arrows on PC, touch joystick on mobile.
The seven
1. Night Shift at Block 13
The one that actually does the job. You're the overnight guard of an apartment block, and the visitors come to the window one at a time claiming to be residents — you check documents, cross-reference the journal, and press the button that lets them in or sends them off. One wrong call and the night is over. The seven-night structure is what makes it work: the building keeps a memory of your mistakes, so a wrong admission stops being a scene and starts being a shift you have to survive. Start here. Play Night Shift at Block 13.
2. Imposter Mission
Take the word "imposter" out of the title and nothing here is deduction. Imposter Mission is a retro horizontal platformer with pixel art: you rotate between a knight, a wizard and a ranger to clear each stage, and the pitch is that sacrificing a teammate is an acceptable way through. It is fast and light and genuinely fine at what it does — it just does something else. Play it if you want an arcade break, not if you want to interrogate a doppelganger. Play Imposter Mission.
3. Diner in the Storm
Closer to a conversation game than a test of judgment. A storm strands you and a handful of strangers in a roadside diner; the danger is outside, not at the table, and the problem you actually solve is convincing the others to leave with you before it gets in. You move with A and D, click to interact with the room, and press space to push dialogue forward. Where Neighbor asks you to read a face, this asks you to talk people round — and being right is not the same as being believed. Play Diner in the Storm.
4. Who Is Imposter
Not a spot-the-difference screen, which is what the title suggests: it's a space-station social-deduction round. You finish crew tasks, keep track of who went down which corridor, and call a meeting once there's a body — then argue about it. Accuse early and you may airlock a crewmate; wait and the saboteur thins the crew for you. Arrow keys run the whole thing, and the game expects other people in the room, which is both its ceiling and its point. Play Who Is Imposter.
5. Imposter Galaxy Killer
A drawing puzzle wearing an imposter costume. You trace a line with a finger or a mouse and the attack follows exactly that path, so the levels become questions about geometry: which curve clears the guards behind cover, which stroke bounces into two targets. Later stages push you toward curves and banks instead of a straight shot. Touch is the native input, which makes this the one entry built for a phone. Play Imposter Galaxy Killer.
6. Stickman Imposter
The viewpoint flips: you are the imposter here, not the one hunting him. You sabotage the ship, pick off the crew one at a time, and the actual difficulty is behavioural — staying unsuspected while everyone else tries to work out who is doing it. Stick-figure art carries the whole thing, which is also why it will run on almost anything with a browser. Arrow keys to move; the tension is all in not looking like the answer. Play Stickman Imposter.
7. Five Nights at Freddy's
The ancestor of the whole night-shift idea, in a browser tab. You sit in a security office, watch camera feeds for animatronics that move when you are not looking, and manage the doors with a mouse. Almost no reading and no verdicts — the decision is where to point the camera next, second by second. If the door-window tension in Neighbor was the part you liked, this is the same nerve applied continuously. Play Five Nights at Freddy's.
Honorable mentions
Two more worth your time if the seven above aren't enough. Imposter Duck: Online is proper online social deduction with a comedy skin — crew missions, a hidden imposter, and the same suspicion loop with ducks instead of crewmates; it runs on WASD or the arrows on a PC and a touch joystick on a phone. And Among U: Red Imposter puts you on the imposter's side in 3D, dragging your character through corridors to hunt crewmates without being seen. Neither reaches Night Shift's atmosphere, but both are quick. Play Imposter Duck: Online or Among U: Red Imposter.
Why this genre exploded
Verification horror works where other horror fails: on low-end hardware, in short sessions, even without sound. The scare lives in your own judgment rather than in rendering budgets or jump-scare volume, so a two-colour stick figure can deliver what a photoreal corridor sometimes can't. That is also why the label gets stretched — plenty of browser games borrow "imposter" without borrowing the mechanics, and telling the two apart before you click is most of what a list like this is for. We'll keep the entries honest as it grows.

Which one should you start with?
If you want the same doorman job, start with Night Shift at Block 13 — it is the only entry here actually checking documents. If you only have five minutes and a phone, Imposter Galaxy Killer is the quickest thing to pick up. And if you'd rather distrust your friends than a stranger at the window, Imposter Duck: Online runs cross-platform with touch on mobile.
