Nintendo World Championships

Nintendo World Championships is a special nationwide promotion/contest in 1990. The legacy of this promotion lies in the game cartridge of the same name which came from it. There are 116 copies of this game known to exist - 90 standard editions, given to contest winners, and 26 gold cartridges given to winners of a related Nintendo Power promotion.

NES Game
The NES games serves as the primary competition in the 1990 Nintendo World Championship. The cartridge has a combination of Super Mario Bros., Rad Racer, and Tetris. Each game is modified for the contest:
 * In Super Mario Bros., the player starts with 99 lives. The game ends when collecting 100 coins, and then Rad Racer starts.
 * After clearing the Rad Racer track, the player can progress to Tetris.
 * Tetris plays in a marathon mode until the timer runs out.

After the player plays a round of each game, their scores are totaled. Each score is adjusted. Players' scores in Super Mario Bros. are multiplied by ten and their scores in Rad Racer are multiplied by a hundred. This encourages players to get to Tetris as quickly as possible and rack up a score in there, as Tetris' score is multiply by 25.

Legacy
The Nintendo World Championship cartridges are considered the "Holy Grail" of NES Collecting by many fans. Gold cartridges are the most sought-after NES cartridges in the history of video gaming, and may go for over $20,000.
