Players control either Neo McDonald or Geo Kentucky in their adventures through Quiz City, a place where answering questions gets results. The genre to these questions include movies, history, geography, songs, sports, and entertainment news. Story progression through the games is largely decided through cutscenes and choices given to players, making the experience very similar to a choose-your-own-adventure.

At the beginning of the game the player can pick up between two modes of play: Story Mode, which is the main gameplay mode, and Sugoroku Mode, which is a competitive two player mode. In Story Mode players can choose between two different scenarios:

- In the first story scenario Neo and Geo are hired by a girl who wants them to find her missing dog. They quickly find the dog on a park but things suddenly get a downturn as they get kidnapped by a mobster and, after escaping, find the girl's place thrashed and end framed for her disappearance. Upon escaping from jail they learn she's been kidnapped by a Hong Kong mafia and travel to the country, discovering that her father was a scientist who was being blackmailed into creating an army of robots to take over the world.
- In the second story scenario Neo and Geo are hired by a man who wants them to find out who was responsible for his own murder before disappearing into thin air. Things quickly get bizarre as they discover a conspiracy to create an army of zombies, with the president seemingly behind it, but at the end they discover the president had been killed and impersonated by Satan himself.
- Sugoroku Mode plays like a board game, where both players compete to find a secret treasure inside of a temple while at the same time facing off against an army of Nazi soldiers who also want the treasure.
