Competition rules
It features the three games: Super Mario Bros., ', and '. The player had a total of 6 minutes 21 seconds to play all three games, but this can be changed by DIP switches on the cartridge.

The player starts out in Super Mario Bros.. They are given 99 lives, and are required to collect 50 coins in the shortest time possible. After completing this, the cartridge moves on to Rad Racer where the player has to complete the first track, again, in the shortest time possible. Finally, they move on to Tetris in marathon mode, and have to get the highest score possible with the remaining time they have left.

After the player plays a round of each game, their scores are totaled and some scores are adjusted. The player's score in Super Mario Bros. is not adjusted, their score in Rad Racer is multiplied by ten, and the score in Tetris is multiplied by 25. This encourages the players to reach Tetris as quickly as possible as it is the best way to achieve high scores.
