**Extra Levels**

These levels are for sandbox type experiences, levels for entities/other levels, or a tutorial for beginners. The levels do not have links, for they don't need one for their short descriptions. These levels have an 'Extra Levels' spot in the level section in Sonic in the Backrooms.

* **Tutorial**

'The Tutorial' is a small level for some basic tips and how to play. There is 1 entity, the Dummy, the docile type. The description for the level in the level select in-game is as follows: "Recommended for new players! An easy, basic level outside of the Backrooms on the basics on how to play, some tips, some tricks, and item uses." The entrance is only from the level select, and to exit, you must complete the tutorial.

* **The Computer**

'The Computer' is a huge black room containing nothing but a table with a computer on top of it. The computer is used for selecting the room style, adding/deleting entities or objects, changing the player's, NPC's or entities' health, adding allies or people, and giving powers. The description reads as follows: "A pitch-black room with nothing but a table and a computer. You can do almost anything you want, like changing the room, adding NPCs/objects and more. The only way to enter is with the level select menu, which you're using right now." To exit, you must pick ''EXIT" on the computer.

* **The Hub**

The hub is a level version of the level select. Each door has a different level to go through. "The hub can access the first 10 levels through each door. There are no entities, and you can't lose hunger, thirst, health or sanity on this level, so it's completely safe. There is a secret entrance in one of the 10 levels, which requires some knowledge." The entrance to the level is by finding the no-clippable wall, completing the puzzle, and finding the right path, with a fail changing the location of the wall. To exit, go through any door.

* **Entity Showcase**
* **Archived Hub**
* **The Arena**
