Night Visitor — the Anomaly Door-Check Game, Play Free [2026]

What is Night Visitor?

Night Visitor is our original door-check game in the anomaly-horror genre: you work the night door with a database of real regulars, and the people knocking are almost right. Cross-check what they claim against what the record says — birth year, height, marks, history — and reject anything that breaks the rules of this world. Humans must be admitted. Anything else must not.

It distills the exact loop that made Home Alone (Anomaly), Terminal 13 and That's Not My Neighbor viral — verify the visitor, trust nothing — into a fast browser game you can play in one sitting.

Features

• Claim vs. database — every visitor states a story; the N.E.T. database holds the truth
• Five tell families — birth-year mismatches, height mismatches, mark mismatches, regulars claiming a first visit, and impossible claims (wizards, magic beans, photosynthesis, levitation, talking dogs)
• Night escalation — deeper nights bring subtler fakes, faster knocks, and double-tell visitors from Night 4
• House rules — the rule banner tightens as nights pass; read it every night
• Three lives — admitting a fake, rejecting a human, or stalling too long all cost one
• Mutable sound + saved best shift

How to Play

1. Press START NIGHT 1.
2. A visitor knocks. Left card = what they claim. Right card = the database record.
3. Compare line by line: name, born, height, mark, and what they say.
4. ADMIT humans, REJECT everything else, before the timer runs out.
5. Survive the nights. The report card remembers your best shift.

Tips

• Read the Says line first — impossible claims are instant rejects and cost nothing to spot.
• Then born → height → mark, in that order. Birth-year fakes are the most common tell on early nights.
• A "first time here" from someone the database lists as a REGULAR is a fake. The reverse (registered 2026 claiming "usual slot") is also a fake.
• From Night 4, assume two tells until proven one. Check everything twice.

FAQs

Is Night Visitor free? Yes — free, no account, no download, works on mobile.

Is it affiliated with any Roblox game? No. It is an original game inspired by the anomaly / identity-check genre; see the genre hub for the games that inspired it.

Why do some visitors look normal but still get rejected? Because the face is never the evidence. The database is the evidence. If the story breaks the rules, the face is irrelevant — that is the whole genre.

Is it scary? It is tense, not gory. No jumpscares; the horror is in the paperwork, which is also why it is fine for older kids.

Conclusion

Night Visitor is the anomaly genre with the 3D stripped off and the pressure left in: normal, normal, normal, wrong story. If you make it past Night 5, you have the exact skill the Home Alone (Anomaly) players brag about — noticing the one detail that does not fit. Play a shift, then go see how the real thing does it.
