Game description (written by KoiArcade)
Haunted House Idle is a 3D idle management game about running a haunted attraction. Walk your character around the house, welcome visitors and send them through the scares, then spend the cash they pay on new rooms: creepy shadows, chasing clowns, a rotating bridge, laser corridors, slime monsters, a photo spot and a mask shop.
Upgrade your own speed and carrying capacity, hire helpers and automate the attractions so the money keeps coming in, and finish tasks to grow the house into a bigger and bigger spooky business.
How to play
- Move with W A S D or the arrow keys.
- Use the mouse to click buttons, upgrades and menus.
- Walk into an area to build or upgrade it.
Tips
- Buy the upgrade with the best income per coin, not the cheapest one.
- Turn the volume up. Sound cues often warn you before something appears.
- Your first few runs are for learning patterns, not for score.
