Continuity mistake: When Bob takes the Obelisk 30 card off Jaden, Jaden's hands are raised. In the next shot, they are suddenly lowered. (00:03:20)
Continuity mistake: When Alexis realises Bob is the loser who has been sending her all those love letters, Bob awkwardly moves back. At this moment, Jaden is standing 90° perpendicular to Alexis and Bob. But in the next shot, when Alexis advances on Jaden, he is suddenly facing her directly. Alexis is also suddenly facing Jaden directly in this shot, even though she was facing Bob in the shot prior. (00:04:22)
Other mistake: When Jaden destroys Slifer 30, Bob tells him he has to drink a full bowl of water in 60 seconds. Once he finishes the bowl, water is shown dripping from his head and splashing up from the bowl, meaning that the bowl couldn't have been empty. (00:14:14)
