Two different things get called "blocked" and they have different answers. There is nothing to download and nothing to install to play Scary Rooms: Idle Horror — it runs inside the browser tab you already have open — so an install restriction on a managed school or work laptop does not stop it. A network filter is the other lock, and no website can honestly speak for that one: whether slowden.com is reachable at all is decided by whoever runs the network you are on, not by SlowDen. If this page loaded for you, Scary Rooms: Idle Horror will play. How to tell the two locks apart in 30 seconds.
