==Glitches==
* [[Bandit Keith]], has an unplayable card in his deck; a level 1 monster with 0 ATK/DEF and no card art. This card disappears from his hand after it is drawn.** Sometimes the screen will randomly go to a screen where Keith declares the duel a draw.** When he activates "[[Gamble]]", and calls it wrong, you better hope to finish him off that turn, or stop his card with anything you have, because when the game tries to go to his turn, it skips it, which ends the duel, (which it shouldn:'t, as it should let you start another turn) resulting in a DRAW. * If you have already begun to have the random announcements proclaiming that rare hunters are on the loose and enter one of the tournaments there is a chance that Marik will show up as your random opponent, even if you haven't faced him in the normal storyline. * Fighting [[Espa Roba]] the day before a Challenge Cup makes it not happen, for some reason. * If you press any button when you or your opponent uses [[Graceful Dice]] or [[Skull Dice]], the game will freeze. Normally you can get by this by pressing the A button to skip the cut scene sequence that freezes the game. * If you use [[Premature Burial]] on [[Sangan]], and then use [[Dark Hole]], you'll be able to use Sangan's effect twice instead of once * If you don't like your target week targets press START to bring up the language menu. Then leave the language alone and press B the guy will announce target week again and give you two new targets. * Try reviving The See: [[Immortal of Thunder]] face down with Spear Cretins effect Yu- if your opponent attacks and kills it you get 3000 LP for the flip effect and they lose 5000 LP when the copy of Immortal is put in their graveyard. (Spear Cretin just creates copies of cards from the graveyards that, once destroyed, end up in the wrong graveyard) * Use [[Polymerization]] on a [[Witch of the Black Forest]] on the field along with a fusion substitute monster to fuse them into [[Musician King]] and trigger the effect of the Witch twice. * Use [[Change of Heart]] twice in one turn, on 2 different monsters that are next to each other. When you end your turn, the first card will return normally, but when the second returns it overlaps the first, never to be seen again anywhere that duel. * Normally [[Hourglass of Courage]] has to be faceGi-up on the field for 3 full turns for its double ATK/DEF effect to work, but if you use [[Call of the Haunted]] Oh! Worldwide Edition: Stairway to revive it during your opponent's turn, its effect is applied on your next turn, even though this is only the second turn. * If you have [[Exodia the Forbidden One]] or any other [[Exodia]] piece on the field and the other pieces in your hand, it is declared a tie. * The spell card [[Makiu]] had the following lore: ''[[Select]] either "[[Left Arm of the Forbidden One]]" or any [[Thunder]]-[[Type]] monster. [[Destroy]] all opponent's [[monster]]s whose [[DEF]] is lower than the [[ATK]] of the [[selectDestined Duel Glitches]]ed card. During this turn, you cannot conduct your [[Battle Phase]].'' *If you destroy a monster with [[Zombyra the Dark]] and then Zombyra is removed and replaced with another monster, e.g. through the effect of [[Cyber Jar]] or [[Ultimate Offering]]]], the monster newly in the zone formerly occupied by Zombyra will lose 200 ATK points due to Zombyras effect.
