Bob Winner is an android sent in search for a lost civilization. He must travel across the world in search of the 3 keys that will grant him access to his goal. Each key is guarded by a different character, and Bob must find special items in order to defeat each guardian.
Bob Winner is a side-scrolling game. Each screen represents a country (the background graphics use digitized photos of well-known monuments like the Eiffel Tower or Big Ben) and has different hazards that must be overcome in order to proceed to the next screen.
The game package included a short comic book describing the back story.
