Tenth-grader Yugi always had his head in some game--until he solved the Millennium Puzzle, an Egyptian artifact containing the spirit of a master gambler from the age of the pharoahs! Possessed by the puzzle, Yugi becomes Yu-Gi-Oh, the King of Games, and challenges evildoers to the Shadow Games...weird games with high stakes and high risks!

While Kaiba, the world's second greatest gamer, duels Pegasus, Yugi and his friends explore Pegasus's castle. But they're not alone! Bandit Keith, the unscrupulous American card shark, prowls the dark castle with his own evil plans. Then, Mai Kujaku finally gets her chance to fight Yugi, and Jonouchi duels it out with Bandit Keith. Jonouchi's deck is loaded with warrior monsters, but Keith's machine deck deals death with six-guns and slot machines...American-style!
