MYSTERY HOUSE

Released by Micro Cabin in 1982, this title stands as a monumental work symbolizing the dawn of graphic adventure games in Japan. While the premise is a simple treasure hunt—exploring a mansion to find hidden jewels—it captivated microcomputer users of the time and pioneered the domestic adventure game market. The PC-8801 version evolved from its predecessors by introducing color graphics, allowing players to enjoy puzzle-solving on a more vivid display. Alongside its international counterparts, this game represents a vital chapter in the history of the genre, and we invite you to experience this foundational work for yourself.

The protagonist steps into a mysterious mansion with the sole goal of finding hidden treasure and making a safe escape. The house is riddled with various traps and puzzles that require the player to input commands to progress through the exploration. Rather than competing against others, this is a pure adventure experience where you must rely on your own wits to locate a hidden diamond within the solitude of the mansion.
