The game says my device has no LiDAR

The game scans your room with the LiDAR scanner, so it runs on iPhone Pro models from iPhone 12 Pro on, and on iPad Pro. Other devices cannot run it.

The scan does not find the walls

Turn the lights on, move slowly, and point the device at each wall from top to bottom. Dark rooms and plain white walls are the hardest; getting closer to the wall helps.

They walk through my furniture

The game keeps learning the room as you look around. Sweep the device over the furniture once before the night starts, and they will go around it.

There is no sound

Check the volume buttons. The game plays its sound even when the silent switch is on.

I bought the full campaign and it is locked

Open the screen with the locked nights and tap Restore purchases. Use the same Apple Account you bought it with.

I want a refund

Purchases are handled by Apple. You can ask for a refund at reportaproblem.apple.com.

Play safely

Play standing up in a lit room with some clear floor, and keep an eye on furniture, pets and people around you.
