About Maniac Mansion
Maniac Mansion is a puzzle adventure about Dave and his friends rescuing Sandy before Dr. Fred uses her in an experiment. You guide their efforts to solve the mysteries of the mansion, including what happened when a meteor landed 20 years ago and how it changed Dr. Fred, Nurse Edna and Weird Ed.
Explore the mansion
You explore room after room, collect unusual objects and investigate the mansion’s mysteries. Along the way, you can find a Green Tentacle and work out how to feed it, discover a chainsaw in the kitchen and a nuclear reactor in the basement, and learn why Dr. Fred keeps saying, “Heh, heh, heh...” The game also asks how Razor gets her hair to stand up like that.
Choose your rescuers
You choose a rescue trio from seven volunteers. Five different ways let you unravel the mystery, with hundreds of ways to guess wrong.
Point-and-click controls
There is no typing: you select characters, objects and actions with point-and-click controls. Maniac Mansion includes both the Original and Enhanced versions.
