Blue-Eyes Ultimate Dragon has no password for the game "Yu-Gi-Oh! The Eternal Duelist Soul," according to IGN's walkthrough. The monster card can be bought from the Premium Pack 3 card packs, which are unlocked after stage four opponents are defeated. Cards appear randomly in the packs.
Blue-Eyes Ultimate Dragon is one of 63 cards that do not have an eight-digit passcode, which players can obtain by looking at the corresponding real-life card. Although technically not a cheat since the game allows users to input these codes, several websites such as Super Cheats, IGN and GameFAQs have information about the passcodes. "Yu-Gi-Oh! The Eternal Duelist Soul" came out in 2002 for the GameBoy Advance handheld system.
