Continuity mistake: When the Duel Ghouls break open the doors to the tennis court and Hassleberry and Axel walk back inside, in the crowd of Ghouls, the first row appears to be an Obelisk Blue student, a Ra Yellow student and a Slifer Red student. In the next shot, a Ra Yellow is now seen where the Obelisk student was standing and an Obelisk Blue student is where the Slifer Red student was standing. (00:17:02)
Continuity mistake: When Pegasus is being fitted with the cyber-design interface and virtual reality headset, there are two cables attached to the left-hand side of the headset that are not attached to the duel disk on his arm. A couple seconds later, the two cables on the left-hand side are suddenly attached to the duel disk. Two cables on the right-hand side of the headset attached to the glove on his right hand also appear from nowhere. (00:00:13)
Continuity mistake: When Crowler walks into the Chancellor's office to see Jaden there, in the first shot of him, his head is upright. When it cuts to a closer shot of him, his head is suddenly shifted to the left. (00:01:09)
Continuity mistake: When the Ghouls are breaking into the tennis court, Alexis says "Our only way out is through them" and she and Jim activate their duel disks.

Revealing mistake: When Pegasus has finished designing the Rainbow Dragon card, Chancellor Shepherd and a group of background extras start applauding. There is one extra wearing a lab coat standing behind Shepherd with black hair, who is reused in the same shot when it pans over to another group of extras on the opposite side of the site.
