[2] Mystery Fun House was produced in only one week[3] and was among the most difficult games in the series.

The player of this game must navigate through a maze[6] and a shooting gallery, charm a mermaid,[7] and turn off a steam calliope that is so loud the player's instructions are misunderstood – a reference to the "Loud Room" in Zork I.

Violent solutions to puzzles are discouraged by a gameplay feature which sees the player character ejected from the fun house by a bouncer whenever certain commands are typed.

[9] Mystery Fun House was among a number of classic Scott Adams adventures made available for free download by non-profit gaming organisation Infinite Frontiers in 2003.

[10] It was also included as part of magnussoft's C64 Classix compilation for Windows and Mac CD-ROM.
