A part of the touring PowerFest 1990 event, the Nintendo World Championships was a competition played with this cartridge. In a 6:21 time limit, players must collect 50 coins in Super Mario Bros. before completing the first stage in Rad Racer. Finally, players will engage in Tetris until the time limit is reached. The final score is tabulated by adding the Super Mario Bros. score to the Rad Racer score (times 10) and the Tetris score (times 25).
