Play Theme Park Mystery Online

Theme Park Mystery is an arcade adventure game released in 1990 for the MS-DOS platform. It was developed by Joined Up Writing Software and published by Konami Corporation. The game presents its environments and action from a side view perspective.

Players control a character whose ordinary life is altered after using a token in a fortune telling machine at a train station. This action provides a ticket to travel through four distinct worlds: Dragonland, Dreamland, Futureland, and Yesterdayland. The core objective involves investigating why visitors have abandoned the theme park and what caused the protagonist's uncle to lose his sanity, with a further goal of avenging the uncle's death. Progression through the game's worlds requires locating specific items such as hidden keys, fiery torches, and supernatural potions.

The gameplay involves navigating the side-view environments of the four themed lands. Players interact with objects and manage inventory items to solve obstacles and advance the story. The structure is built around exploration and item collection, with the fantastical settings providing the context for the adventure.
