HD Escape Rooms

HD's escape rooms are built into the basement of an actual 1889 Denver mansion, in the space where a real Prohibition-era speakeasy once operated (the original bootlegging tunnels are still part of the lore). The setting is genuine historic architecture, not a soundstage, and the puzzles and props are custom-built locally with the crew behind Frightmare Compound rather than pulled from a franchise kit. The flagship room leans into the building's haunted history, with staff tying the puzzles to the mansion's real backstory as you solve it.

The move: Pick the speakeasy or haunted room, get locked in for 60 minutes, and race the clock together solving hand-built puzzles in a real 19th-century basement.
