Continuity mistake: When Yugi opens the door to the lower level, Tea approaches beside him. At first, she is slightly behind Yugi, but when the shot cuts, the two are side by side. (00:02:16)
Continuity mistake: When Kaiba is testing the new duel disk system, Mokuba is watching from the room above. In the background, there is a wall that is a light teal colour to the left of the shot and another wall further back that is a dark teal colour. When the shot cuts to Mokuba saying "You're crazy if you go through with this, Seto," the wall behind him is entirely the dark teal colour. (00:05:40)
Continuity mistake: When the duel robot ends its first turn, in the shot of the monster being set face down, Kaiba has his right arm lowered. When the shot cuts to Kaiba, his right hand is suddenly raised and holding onto one of the duelling cards. (00:08:59)
Continuity mistake: After the robot summons Blue-Eyes White Dragon, it ends its turn after seeing Kaiba's face-down card. In the shot where the robot says "End turn," the cards on Kaiba's duel disk are missing the illustrations. (00:10:29)
Continuity mistake: After Kaiba summons Dragon Seeker, the duel robot begins saying "Analysing Dragon Seeker." There are six cards shown in the card slots on the robot. When the shot cuts, there are only five cards in the slots. Also, one of the slots that was empty in the previous shot now suddenly has a card in it when the shot cuts. (00:11:02)
Continuity mistake: Just after Kaiba has won the duel, a scientist says, "Shut down the power source right away," whilst standing next to Mokuba. It then cuts to a closer shot of Mokuba, and the scientist standing next to him cannot be seen. (00:15:21)
