Backrooms Levels Explained: the Main Nine and How Many There Are

Which Backrooms is this? Everything below is the fan-written Backrooms Database on Fandom, where the numbered levels come from. Kane Pixels’ series and the A24 film don’t have numbered levels. If you’re not sure which version you’ve been watching, start with which Backrooms is canon.

What is a level in the Backrooms?

A level is one self-contained space inside the Backrooms, with its own look, rules and dangers. In the Backrooms Database, levels are “subspaces” that together make up the Backrooms. Some are indoors, some are entirely outdoors, and some are open worlds. Normal geography stops applying: a level has no fixed climate, location or time, it can slowly change, and it can even stop existing.

Wanderers often picture the levels as the floors of a building, and moving to higher-numbered levels can feel like you’re going “higher up”. You get between them by finding exits (a door, a staircase, a hole in the floor) or by noclipping: a few seconds at most of darkness and falling through the Void, thought to be the space between levels. A few wanderers fall far longer, or go missing entirely.

There are three kinds:

• Numbered levels (Level 0, Level 37, Level 777…). In-world, each level has a “level key” that gives off a radio frequency, and that frequency is the level’s number.
• Anomalous levels (Level Fun, Level !, The End…). Their keys give off no frequency, so they have no number and are named after their strangest feature. They tend to ignore the rules the numbered levels follow.
• Sublevels (Level 0.1, Level 7.5…). Variations of a parent level that aren’t different enough to be levels of their own.

How many levels are there in the Backrooms?

About 800, and the number keeps changing. On 17 October 2026 the Backrooms Database filed 802 pages under levels. Because it’s written by fans, pages are added, rewritten and deleted all the time, so treat any exact count as a snapshot.

The numbered list runs from Level 0 to Level 999, plus dozens of decimal sublevels. Not every slot is filled: many numbers in the 900s are still marked “no data”. At 999 the list stops with a note that, under the site’s Rule 6.1, new numbered levels beyond that point are currently forbidden. A separate “Cluster II” begins at Level 1000. Then come the anomalous levels and a handful of in-between spaces such as the Void.

The Main Nine: Levels 0 to 8

The Main Nine are Levels 0 through 8, the “core” levels of the Backrooms. Older versions of the story treated them as the only levels that exist. Today the database says all documented levels are real unless their page says otherwise, but these nine are still the most influential.

Each level has a threat class: higher numbers mean more danger, “Habitable” marks a level people can actually live on, and “Undetermined” means nobody can rate it yet.

Level	Name	Threat class	What it’s like, and what gets you
0	The Lobby	Class 1 · no entities	Yellow wallpaper, damp carpet, endless hum-buzz. No food or clean water, so people die of dehydration, exhaustion or starvation; the looping rooms wear down your mind. Full Level 0 guide
1	Parking Zone	Class 1 · few entities	A huge concrete parking garage with reliable power for its lights and outlets. Upstairs, the foggy “Luxury Lots” have outlets whose output can reach a gigawatt
2	Pipe Dreams	Class 2 · unsafe	Humid, rusting utility tunnels. Visitors from Earth burn extra energy and overproduce adrenaline when they run, and a living pipeline up to 200 km long digests anything that stops moving for a few hours
3	Electrical Station	Class 2 · page being rewritten	Derelict maintenance halls full of humming electrical machinery. The page is mid-rewrite, so expect details to change
4	The Abandoned Office	Class Habitable · no entities	Empty offices and cubicles with rain on the windows and almond water in the vending machines. Tens, if not hundreds, of thousands live here. Most exits drop you into the Void
5	Terror Hotel	Class 5 · entities unconfirmed	An endless 1930s hotel with ballrooms, pools and distant jazz. Residents keep finding bodies with no wounds, only foam from the pores and twisted postures
6	Lights Out	Class Undetermined	A barren tundra in total darkness. Flashlights and fires go out, electronics fail, the ground collapses, and the dark brings on microsleep. Most wanderers who reach it go no further
7	Thalassophobia	Class 3	A flooded bunker at 4 °C leads up to an endless, foggy, nearly still ocean. Something enormous drifts in it (the Thing on Level 7), and in places the water’s gravity points sideways or up
8	Cave System	Class 3 · page being rewritten	Huge caves and cramped burrows. Few have gone deep, and even fewer have made it back. Its page is also being rewritten

Levels 3 and 8 are both under rewrite and marked as candidates for deletion as of 17 October 2026, so we’ve given each only one line. We’ll update this table when their new versions land.

What is the most dangerous level in the Backrooms?

Level !, also called “Run For Your Life”, is described as the most dangerous anomalous level in the Backrooms. You enter through a door marked with a huge red exclamation mark, it slams behind you, and almost every kind of entity chases you down a ten-kilometre hallway full of fake exits. Very few people who enter ever escape. It’s rated Class 5.

Among the Main Nine, Level 5, the Terror Hotel, has the highest rating (Class 5), even though no entity there has been confirmed: people simply die there, and nobody knows why.

Famous levels outside the Main Nine

These are the levels people search for most after the first nine. One line each; the database has a full page for every one.

Level	Name	In one line
Level Fun	(anomalous)	A warehouse of bounce houses behind gym doors painted with animals. The floors can swallow you whole, and the only exit, a slide, leads deeper in
Level !	Run For Your Life	The ten-kilometre chase above. Class 5
Level 37	Sublimity, “the Poolrooms”	Endless white-tiled rooms in lukewarm, rippling water. Class 1 and no entities, but its dark, deep sections can drown you
Level 94	Haphazard Remnants	An outdoor patchwork of terrains scattered with copies of famous landmarks at random sizes. Class 3e (environmental)
Level 777	The Illusion	Rebuilds a place you feel attached to (your home, your school) and convinces you that you belong there. The longer you stay, the more dangerous it gets. Class Undetermined
Level 999	Tower of Babel	Told as one wanderer’s account: a foggy desert walk towards an endless tower, past dead expeditioners

If you remember a different version of a level with the same number, you’re probably thinking of another fan site. Names and numbers often don’t match between projects (see below).

Is there a last level? What about Level 9999?

No last level has been confirmed in the Backrooms Database, and Level 9999 doesn’t have a page there. We checked on 17 October 2026: searching for Level 9999 returns nothing. Level 9999 and “the true final level” come from other fan projects and videos, not this version of the Backrooms, so there’s nothing in this canon to describe.

What does exist:

• The numbered list stops at Level 999 because of a site rule, not because the Backrooms ends there in-world, and Level 1000 already starts a second cluster.
• There’s an anomalous level called The End: an apparently infinite, empty library. Despite the name, it isn’t the bottom of the Backrooms. Its own description calls it an in-between space between levels, and one way out is a door that leads to a random level.

So in this canon, the Backrooms doesn’t really end. The list just keeps growing.

Why do level names differ between sites? (Lobby vs Threshold)

Because there’s more than one fan-written Backrooms. The Backrooms Database on Fandom calls Level 0 “The Lobby”. The separate Wikidot project, which the Fandom database itself calls its largest branch-off, calls Level 0 “Threshold”. The two sites write their own pages, so the same number can mean a different place, and search results and AI answers often blend them.

This guide sticks to the Fandom database throughout. Kane Pixels’ series is a third version again: it has no numbered levels at all, and in it “the Threshold” means something completely different. The canon guide lays all of them out side by side.
