The Backrooms are endless yellow hallways, full of strange creatures. There are two different things with this name:

Step on the television in Evopolis. A window opens with the channels: each channel is a layer of the map. Choose one and you are sucked into the screen.
To leave, look for one of the return TVs in the layer where you are and step on it. You cannot leave during combat.
Every day the hallways are different. So there is no use memorizing the way: the minimap is also reset when the map changes.
Creatures spawn in groups when you get close, outside your screen. A dead group comes back after 60 seconds, when someone passes near again.
The names of the creatures appear with letters that cannot be read. This is on purpose.
Layers
The map has 3 layers, starting from the side where you spawn. The farther you go, the stronger the creatures and the bigger the groups.
| Channel | Creatures | Per group |
|---|---|---|
| 1 (weak) | Spiral Girl, Lost Scientist, Bone Hound | 8 |
| 2 (medium) | Faceless Bridge, Longneck, Shadow Puddle | 10 |
| 3 (strong) | Music Box, Red Giant, Wheelchair Crone and, rarely, the Backrooms Crow | 12 |
Tiers
The Backrooms has 7 copies, one for each tier. You land in the tier that matches your level (or proficiency, at max level). In a party, you enter the party's tier. If you go past the limit of your tier, the walls change and you go to the next one.
| Tier | Who enters | Creature health | Creature damage |
|---|---|---|---|
| 1 | level below 700 | 1x | 1x |
| 2 | level below 1,000 | 1.83x | 1.71x |
| 3 | level below 2,000 | 12.82x | 3x |
| 4 | level below 2,500 | 85.91x | 13.28x |
| 5 | proficiency up to 900 | 938x | 46.83x |
| 6 | proficiency up to 2,200 | 6,995x | 521.8x |
| 7 | above that | 17,051x | 1,923x |
The exp in the Backrooms is fixed: the whole day is worth 5 levels (or 5 proficiency levels, at max level), split into 1,000 kills. Each kill gives 1/1,000 of that, before exp bonuses.
After 1,000 kills in one day, creatures stop giving exp until the reset at midnight (server time).
Each creature that spawns has a 1% chance to be its boss version: another color, 10 times the health and double the damage.
A mini-boss counts as 10 kills, both for exp and for the daily limit. At most 5 alive per copy.
Some walls have doors (4 per layer). Click one and you come out through another door in the same layer, chosen at random. It works during combat.
The values are those of tier 1. In the other tiers, multiply by the tier table. All of them give the same exp.

Rare Only in layer 3: about 1 in every 200 creatures.

The King of Pop walks around in each copy of the Backrooms. He only walks with a moonwalk, does not attack and cannot be attacked. When he sees someone, he runs away faster than you and goes through furniture.
| Catch | Reward |
|---|---|
| 1st time | 1 Skill Tree point (only once per character) |
| From the 2nd on | Blue Diamond (in the purse) |
A repeatable quest from Doctor Ellery, the researcher at the entrance of the Backrooms (he stays outside, in the city).
Geiger Counter.Color Bosses
The boss is a giant crow of one of 5 colors, chosen at random. Its strength follows the tier of the copy you came from. Each color has an attack with a warning on the floor:
| Color | How it fights | Warned attack |
|---|---|---|
| Green | More health | Area around it: 15% damage and, if it hits, it heals the boss by 8% |
| Red | Hits hard up close | Small area: 12% damage and pulls you close to it |
| Purple | Strong from far away | Area around it, comes many times: 30% damage |
| Blue | Fast to move and attack | A strip toward you, and it charges along it: 25% damage |
| Yellow | Can crit | Small area that kills instantly. Always get out of it |
Rewards
They depend on the tier of the copy. The layer where the TV was increases everything: layer 2 gives 25% more and layer 3 gives 50% more.
| Tier | Blue Diamond | Serums |
|---|---|---|
| 1 | 1x | 1x |
| 2 | 2x | 1x |
| 3 | 3x | 2x |
| 4 | 4x | 2x |
| 5 | 5x | 3x |
| 6 | 6x | 3x |
| 7 | 8x | 4x |
Each color boss leaves a serum of its color. You can only use the serum after Doctor Ellery studies that color (the first win with it).
Using a serum spends the whole stack and fills the level of that color. When it fills, the level goes up. There is no maximum level.
| Serum | Bonus per level |
|---|---|
Green (Green Syringe) | +1% health and +1% mana |
Red (Red Syringe) | +1% basic attack damage |
Purple (Purple Syringe) | +1% spell damage |
Blue (Blue Syringe) | +5 speed (anything above the level limit counts half) |
Yellow (Yellow Syringe) | +1% critical damage |
| Level | 1 | 2 | 3 | 4 | 5 | 6 | After that |
|---|---|---|---|---|---|---|---|
| Serums to level up | 1 | 5 | 10 | 15 | 20 | 25 | +5 each level |
A game of survival in the dark. With 2 to 40 players. When the event opens, enter through the teleport in the event room. The waiting room stays open for 5 minutes.
You go to the glass gallery and watch the rest of the round from above. In the next round you come back.
Noise and Running
The Creatures
The Crow Man starts hunting right at the start (1 for every 8 players, up to 3). After that, other creatures come out of the wall doors, without warning:
| When | Creature | How it hunts | Hit |
|---|---|---|---|
| Start | Crow Man | Sees 7 squares in front of it and hears footsteps. Goes to the last step of anyone who keeps walking. Gets faster every minute. | 500 |
| 45 s | Red Giant | Slow, but sees far (10 squares). | 670 |
| 90 s | Neck Thing | Fast and almost blind: hunts by sound. Running near it is death. | 500 |
| 135 s | Faceless Bridge | Slow and huge. Patrols the hallways and does not chase far (gives up after 8 squares). | 500 |
