Backrooms Game is a scary game based on a scary story on the internet with the same name. The game is based on the idea that there are infinite levels of rooms behind the walls of reality and that if you accidentally clip through them, you will be stuck in a limbo of endless yellow halls and carpets. The goal of the backrooms game (https://backroomsgame.net/) is to get out of this nightmare while avoiding the unknown things that are hiding in the dark.
How do you play Backrooms?
You need a gadget that can connect to the internet and a browser to play the Backrooms (https://backroomsgame.net/) Game.
There are different levels in the game, and each one represents a deeper level of the backrooms. Every level has its own plan, theme, and dangers. Some levels have elevators or portals that let you get to other floors. Some levels also have special features or events that can help or hurt your progress. In the back rooms, you never know what to expect, so be ready for anything.
The game also has a method for sanity that changes how you see reality. As you go through the back rooms, your mind will slowly start to go down. If it goes down to zero, you lose the game. Find safe places, which are marked by green lights, to get your mind back. Some things, like pills or water bottles, can also help you stay sane.

There are many great online games accessible; I usually play 1v1.lol unblocked (https://1v1lolunblocked.io/) in my free time. A fairly interesting shooter survival game, actually.
