Someone knocks, and their story sounds almost right. In Home Alone, every door visitor can be a real person or an Anomaly wearing the same face, so you verify the claim before you open up. Each visitor has a main tell: a house object, laptop cameras, night vision, voice, outside view, or something you can see on them at the door.
section
House Checks
These visitors claim something is wrong inside the house. Stay locked, walk to the object they named (cat by the bed, oven, bath faucet, or sink), then decide. If the house matches the story, open the door; if it does not, turn the porch light off.
Cat Lady
House check first. Black cat by the bed is safe; white cat means reject with the porch light.
- Detect by
- House check
- Request
- Wants her missing black cat back from your parents' bedroom.
- Anomaly signs
- Before you open up, check the parents' bedroom. A white cat next to the bed means she is lying about a black cat.
- Best action
- Open the door and return the black cat if it matches. Turn the porch light off if the cat is white.
Firefighter
Always verify the oven before you trust a firefighter at the door.
- Detect by
- House check
- Request
- Claims smoke is coming from your oven and needs to put the fire out.
- Anomaly signs
- Check the oven. No smoke means the firefighter story is fake.
- Best action
- Open the door if the oven is smoking. Turn the porch light off if there is no smoke.
Plumber
Confirm the leaky bath faucet before you let the plumber in.
- Detect by
- House check
- Request
- Says he was called to fix a leaky bath faucet.
- Anomaly signs
- Check the bath faucet. If nothing is leaking, he is an Anomaly.
- Best action
- Open the door if the faucet is leaking. Turn the porch light off if it is dry.
City Maintenance
Sink check decides this one: brown water is real, no water is fake.
- Detect by
- House check
- Request
- Claims the water has turned brown and needs to fix it.
- Anomaly signs
- Run the sink. No water at all means he is an Anomaly.
- Best action
- Open the door if the sink water is brown. Turn the porch light off if nothing comes out.
section
Camera Checks
Front-room laptop cameras catch these fakes. Check the door cam, backyard cam, or mum's-car cam as needed, and listen for glitchy shutter audio on the wifi kid. What you see (or do not see) on the feed beats the story at the door.
Dumped Girl
Camera check for a false smile and direct stare before you trust the crying act.
- Detect by
- Cameras
- Request
- Asks for tissues to wipe her tears.
- Anomaly signs
- On the laptop cameras she is smiling and staring straight at you instead of crying.
- Best action
- Turn the porch light off if the camera shows a smile and stare. Open the door if she still looks upset on cam.
Ballerina
Use the door camera: dancing on the porch means Anomaly, standing still is safe.
- Detect by
- Cameras
- Request
- Wants to dance for you.
- Anomaly signs
- Laptop cameras show her dancing on the doorstep.
- Best action
- Turn the porch light off if she is dancing on cam. Open the door if she is standing normally.

- Detect by
- Cameras
- Request
- Asks you for food.
- Anomaly signs

- Cameras
- Request
- Wants to collect his dog from your backyard.
- Anomaly signs
- Backyard camera shows the dog owner hunched on all fours and barking instead of a dog.
- Best action

Wifi Kid
Listen for camera shutter glitches when this kid is at the door.
- Detect by
- Cameras
- Request
- Wants the wifi password.
- Anomaly signs
- Opening the cameras triggers a glitchy shutter-click noise repeating over the feed.
- Best action
- Turn the porch light off if the camera audio glitches. Open the door if the feed sounds normal.
Obby Player
Switch to the car camera. Fist-smashing the car means Anomaly.
- Detect by
- Cameras
- Request
- Wants to play Roblox with you.
- Anomaly signs
- The camera on your mum's car shows him smashing the car with his fist.
- Best action
- Turn the porch light off if he is wrecking the car on cam. Open the door if that camera stays normal.
section
Night Vision Checks
Toggle night vision on the laptop while they stand on the porch. Compare that view to the normal cam: face-on-lens, sudden height changes, alien form, giant size, or a head snap all mean reject.
New Neighbour
Toggle night vision. A face mashed into the camera means reject.
- Detect by
- Night vision
- Request
- Introduces himself as your new neighbour and wants to meet you.
- Anomaly signs
- On night vision his face is pressed up against the camera screen.
- Best action
- Turn the porch light off if night vision shows a face on the screen. Open the door if he stays normal.
Guy Who Needs To Pee
Compare normal cam to night vision. A sudden height jump is the Anomaly tell.
- Detect by
- Night vision
- Request
- Needs to use your bathroom.
- Anomaly signs
- Night vision makes him look noticeably taller than the normal camera view.
- Best action
- Turn the porch light off if night vision stretches him taller. Open the door if his size stays consistent.
Secret Agent
Night vision is the whole test: alien form means Anomaly.
- Detect by
- Night vision
- Request
- Wants to warn you about an alien threat in the neighbourhood.
- Anomaly signs
- Night vision turns him into a roughly 7-foot alien.
- Best action
- Turn the porch light off if night vision shows an alien. Open the door if he stays human on night vision.

- Anomaly signs
- On night vision her head snaps forward unnaturally.
- Best action
- Turn the porch light off if her head snaps on night vision. Open the door if nothing changes.
section
Voice Checks
Stay at the door and hear the full line. A demonic voice swap, a melodic echo, or a pitch that does not match the body is the Anomaly tell. Steady, normal speech is the safe version.
Classmate
Listen through the whole line. A demonic voice swap means Anomaly.
- Detect by
- Voice
- Request
- Wants to work on homework together.
- Anomaly signs
- Voice flips between a normal kid tone and a gravelly demonic voice.

A melodic echo on her voice is the reject signal.
- Detect by
- Voice
- Request
- Invites you to a party.
- Anomaly signs
- Her voice echoes in a melodic, unnatural way.
- Best action
- Turn the porch light off if the voice echoes melodically. Open the door if she sounds normal.

Trust your ears: an ultra-high voice on a huge gym visitor is the Anomaly.
- Detect by
- Voice
- Request
- Needs water for a protein shake.
- Anomaly signs
- Voice is extremely high-pitched instead of matching his build.
- Best action
- Turn the porch light off if the voice is high-pitched. Open the door if he sounds normal.
section
Outside Checks
Before you trust a uniform, look past the visitor. A real police visit has a police car out front; a beat-up van is the fake.
Police Man
Look outside first: police car is safe, beat-up van is Anomaly.
- Detect by
- Outside view
- Request
- Wants to come inside to check for a roaming criminal.
- Anomaly signs
- A beat-up van is parked in front of the house instead of a police car.
- Best action
- Turn the porch light off if you see a beat-up van. Open the door if a police car is parked outside.
section
Appearance Checks
The streamer is decided by what is in their hands. A giant phone supports the livestream story; empty hands do not.
Streamer
Check the hands. Giant phone is real streamer energy; empty hands mean Anomaly.
- Detect by
- Appearance
- Request
- Wants to feature you on a livestream.
- Anomaly signs
- No phone in hand while claiming to stream.
- Best action
- Turn the porch light off if there is no phone. Open the door if the giant phone is out.

- Anomaly signs
- No confirmed safe form is documented. Treat any vampire invitation as an Anomaly.

section
House Scares
Not a door visitor. The goblin stalker can jump out while you move around the house, but it cannot harm you. Ignore it and keep doing door checks and chores.
Goblin Stalker
House scare only. Spooky, not deadly—keep working the door checks and chores.
- Detect by
- House scare
- Request
- Jumpscares you inside the house. Not a door visitor.
- Anomaly signs
- A permanent house jumpscare figure that can appear while you move around.
- Best action
- Ignore it. It cannot harm you.
How the door loop works
When someone knocks, talk through the door and listen to what they want. Most visitors have two forms: a safe one that matches their story, and an Anomaly form that fails a specific check. Your job is to prove the story before you open the door.
If they are real, open up and deal with the request (return a cat, fix a leak, give water, and so on). If they are fake, turn the porch light off (the switch sits to the right of the door). That is how you reject them. Letting an Anomaly in drains Sanity. Rejecting a real visitor also hurts Sanity, so guessing is expensive either way.
Checks that save runs
- House checks: Leave the door closed, walk to the object they mentioned (bedside cat, oven, bath faucet, sink), then come back with an answer.
- Cameras: Use the laptop in the front room. Some fakes smile when they should cry, dance on the step, vanish from the feed, bark in the backyard, glitch the audio, or smash your mum's car on a side cam.
- Night vision: Toggle night vision on the laptop feed. Faces mash into the lens, height jumps, human suits become aliens, small kids go giant, or a head snaps forward.
- Voice: Stay at the door and keep listening. Demonic flips, melodic echoes, or a voice that does not match the body are all reject signals.
- Outside and looks: Peek for a police car vs a beat-up van, or check whether a streamer is actually holding a phone.
Easy mistakes
Do not open because the outfit looks official. Firefighters, plumbers, cops, and agents all have fake versions. Do not skip the laptop when a visitor is camera-based; the front-door view alone is not enough for every tell. Night vision and normal cam should be compared side by side when height or form is the clue.
A few rules break the dual-form pattern. The Vampire has no documented safe form, so keep the porch light off and refuse the invite. The Goblin Stalker is not a door visitor at all: it jumpscares you around the house and cannot hurt you, so ignore it and keep working the door.
When you are unsure, re-run the check the visitor is known for before you touch the handle. One clean verify is safer than a fast open.
FAQ
How do you reject an Anomaly in Home Alone?
Turn the porch light off. The switch is to the right of the door. That refuses the visitor without opening up.
What happens if you let the wrong visitor in?
Admitting an Anomaly lowers your Sanity. Rejecting a real visitor also hurts Sanity, so always verify the specific tell before you open or kill the light.
Where do you check cameras and night vision?
Use the laptop in the front room. Normal camera views cover the door, backyard, and other spots; night vision is a toggle on that same feed for several visitors.
Can a visitor be both real and an Anomaly?
Yes for most door visitors. The same face can show up with matching evidence (safe) or failed evidence (Anomaly). Run the check for that visitor every time instead of memorizing one answer forever.
Is the Vampire ever safe to invite in?
No safe form is documented. Treat every vampire invitation as an Anomaly: keep the porch light off and do not invite them inside.
Does the Goblin Stalker end your run?
No. It is a house jumpscare, not a door visitor, and it cannot harm you. Spooky only: keep working the door checks.
