Mario Tennis GB — About this game
Mario Tennis GB on Game Boy Color combines tennis matches with a role-playing journey through the Royal Tennis Academy. Choose Alex or Nina for Mario Tour, train and improve your player, or enter Exhibition to play matches with familiar Mario characters.
Success depends on positioning and shot selection: topspin, slices, lobs and drop shots force opponents to cover different parts of the court. Academy progression gives practice a purpose as your player develops and faces stronger rivals.
