Nintendo World Championships 1990

The Nintendo World Championships 1990 is a special version of the Nintendo Entertainment System. There are only 116 cartridges in existence, and they were used for the Nintendo World Championships held from March 8, 1990 to December 9, 1990 in 29 cities across the United States. 90 gray cartridges were given to the ninety finalists, and 26 gold cartridges were given away in a Nintendo Power contest. Because of this, the Nintendo World Championships 1990 is an extremely rare cartridge that usually sells for high prices.

The Nintendo World Championships 1990 features Super Mario Bros., Rad Racer, and Tetris as games. During the contest, all three games could only be played for a total of 6 minutes and 21 seconds, but this could be changed via DIP switches on the cartridge.

The first playable game is Super Mario Bros.. Players are given 99 lives, and are required to collect 50 coins in the shortest time possible. After completing Super Mario Bros., the cartridge moves on to Rad Racer, where the player must complete the first track of the game in the shortest time possible. Finally, players can play Tetris in marathon mode, and they 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 Rad Racer and Tetris are multiplied by 10 and 25, respectively.

The Nintendo World Championships 1990 is referenced in NES Remix 2's Competition Mode, which is set up like the cartridge.
