Yugi is trapped inside the Duel Dome, and the only way to escape is by defeating the Duel Computer – a calculating contraption programmed with the skills of the world’s top duelists!  Since the Duel Computer has access to thousands of cards to create a devastating deck, how can Yugi win when he’s forced to use an amateur deck that barely contains any spell or trap cards?
We can't leave unless we defeat the Duel Computer.
