Open House is a short indie horror game about a seemingly normal house showing that turns increasingly unsettling as you explore it. In the version most people mean, you play as a prospective buyer using a real-estate-style simulator, but the house starts revealing creepy, unnatural details and hidden danger.

What it’s about

The game begins like a standard open house or home-tour experience, then shifts into psychological horror as the environment and atmosphere become more disturbing. The core hook is that something feels wrong inside a place that should feel safe.

Main idea

  • It uses a real estate / house-viewing setup as the premise.
  • The horror comes from atmosphere, strange events, and jump scares rather than action-heavy gameplay.
  • The story is usually framed as a “fresh start” that quickly goes bad.

Why people talk about it

People often remember it because the contrast is so sharp: a calm house-tour setup that becomes creepy fast. That makes it stand out as a compact horror experience rather than a long story game.

One note

There are also other horror projects using the name “Open House,” including newer psychological horror demos, so if you want, I can identify the specific one you mean and summarize that exact version.
