Build Your Backrooms

Ever wanted to be the mastermind behind the internet's most iconic horror phenomenon? Build Your Backrooms hands you the architect tools to design the ultimate nightmare! Step into the role of the maze creator and build endless, claustrophobic yellow corridors packed with blind corners, treacherous traps, and unsettling dead ends.

Once your layout is locked in, it's time to stock the halls with terror. Place terrifying monsters across the map to hunt down unsuspecting characters wandering through your creation. Every captured victim converts straight into cold hard cash! Use your profits to expand your maze, set deadlier traps, and unlock terrifying new entity types. Want a hands-on approach? Take direct control of your monsters, stalk the hallways yourself, and hunt down prey in first-person view!
