Nintendo World Championships '94 was a 1994 Nintendo-promoted video game competition held during the Nintendo Powerfest '94 tour. Most of the town competitions were held in customized trailers outside of department stores. It was based on scoring points in a special Game Pak. The three Super Nintendo Entertainment System games (Super Mario Bros.: The Lost Levels, Super Mario Kart, and Ken Griffey, Jr. Presents Major League Baseball) were played within a time limit of six minutes.
