From a 2019 4chan post to a record-breaking A24 movie, the Backrooms became the internet's favorite nightmare. Here's what they actually are — and a free Backrooms game you can play in your browser right now.
The short answer
The Backrooms are a fictional, internet-born horror setting: a near-infinite maze of empty, off-putting rooms you "noclip" into when you slip out of reality. The most famous version is Level 0 — endless mono-yellow rooms, damp carpet, moist walls, and the constant hum of fluorescent lights. It's the ultimate liminal space: somewhere familiar, empty, and deeply wrong.
Where the Backrooms came from
It started in May 2019 with a single 4chan post: a grainy photo of empty yellow rooms and a caption about "noclipping out of reality." That image spawned a sprawling, community-built mythology.
The phenomenon exploded in 2022 when a teenager named Kane Parsons — under the channel Kane Pixels — released a found-footage Backrooms video that racked up tens of millions of views and defined the modern look of the Backrooms. Fast-forward to 2026: Parsons directed A24's The Backrooms film, which opened May 29, 2026 and became A24's highest-grossing movie ever (over $262M worldwide), making him the youngest filmmaker to top the box office.
The levels (community lore)
The Backrooms "levels" are crowd-sourced fan canon — there's no single official map — but the most well-known include:
- Level 0 — the original yellow rooms
- The Poolrooms — eerie, sunlit tiled chambers full of shallow water (a fan favorite)
- Deeper, stranger levels — vast warehouses, parking garages, offices, and worse, each with their own rules
The entities
You're not alone down there. Community lore is full of creatures — things that mimic, things that hunt, things that only move when you're not looking. The horror is rarely about fighting them; it's about avoiding them in spaces with no clear exit.
Why it took over the internet
The Backrooms hits a specific nerve — the unease of empty malls, vacant offices, and abandoned pools. It's open-source horror: anyone can add a level, an entity, or a story. That's why there are now 500+ Backrooms games on Steam and countless videos, and why the format keeps growing.

The best way to understand the Backrooms is to wander them. We built a free, browser-based Backrooms game on Rosebud AI — no download, no signup.

It puts you in first-person in the classic Level 0, with a clever twist: the monsters are your only source of points. Keep them in sight for steady points, survive a chase for big ones, but getting caught is brutal — and hiding in a corner makes your score decay. It's also multiplayer: pick a name, choose an avatar, and share the halls with others.
Want to make your own Backrooms?
The Backrooms has always been participatory — people build their own levels and entities. On Rosebud you can do exactly that without coding: fork the game and, because the core gameplay already works, just personalize it — reskin Level 0 into the Poolrooms, add your own creatures, build new levels — by chatting with Rosie, the AI assistant. Here's how to make a Backrooms game.
