Description:

Exact descriptions of Level 1 vary somewhat, though most major details remain the same. The floor of this level has been described as being many things, like tile, carpet, pavement, or even natural materials like grass or sand. Yet the grimy environment and low-hanging fog are almost always the same. In some places, the walls have been painted with scenery to match the floor, but no one knows why.

However, the most common "theme" in Level 1 is similar to the mono-yellow design of Level 0. The key differences are a lack of wallpaper and moisture in the carpet, and quieter fluorescent lights. Beings typically lurk at or above Level 1. Known beings on Level 1 include Dullers, Adult Facelings, Hounds, and Skin-Stealers.

There are multiple ways of reaching Level 1. Like other levels, it can be reached randomly with stairs, elevators, and hallways, and one also has a small chance of landing here when first noclipping into the Backrooms. In addition, at any point, there's a chance the lights will begin to flicker on and off. Eventually, the lights will turn off for minutes or hours at a time. While the lights are off, this level becomes very dangerous, so bring a light source if you're exploring.

Level 1 is home to the Hub.

Entrances and Exits:

Entrances

Get here from Level 0. In Level 11, if you walk into a building, you may end up here. If you climb one of the trees in Level 11.1 you will have a chance of entering Level 1. Open one of the doors in Level 4.1 to enter this level. Enter one of the unlocked doors in Level 54 to get to Level 1. Walking through one of the doors in Level 82 can lead you to Level 1. The end of the fifth event in Level 92 can lead you here. You can get here after completing The King's trial in Level 94. No-clip through any ceiling in Level 283's Lounges to get to Level 1

Exits

You can leave Level 1 by simply continuing to explore the Backrooms. Level 1 usually leads to Level 2 or back to Level 0. In Level 1, it is possible to find holes in the walls that will lead to Level 19, which are very rare. Entering a dark wall can rarely lead to Level 28. Rarely, you may be transported to Level 38 randomly. No-clip through the ceiling and you will end up at a party! =)
