The Darkness Returns: Part 1 - S3-E28
Continuity mistake: When Tristan attempts to leave the tower to tell Serenity about the next duel, Mokuba calls out to him. The wall next to Mokuba has nothing on it, but in the next shot, a phone has suddenly appeared on the wall, which Mokuba then uses. (00:01:51)
Back to Battle City: Part 3 - S3-E27
Continuity mistake: At the start of the episode, in the wide shots of the duelling room, the platform that Yugi is standing in is several meters below the number 2000. This is because Yugi has 3000 life points, and the platform's position depends on what the duelist's life points are. When Marik says to himself, "Crushing the Pharaoh is a much more appealing choice," the platform Yugi is standing on is now aligned with the number 2000 (which shouldn't be the case since his life points are 3000). (00:02:13 - 00:02:52)
Back to Battle City: Part 1 - S3-E25
Continuity mistake: When the main characters walk inside the tower, in the wide shot of Roland saying the Battle City finals will take place there, all of the characters are facing the same direction. In the next shot, Yugi, Joey, and Tristan are all facing different directions from one another. Also, the other characters cannot be seen in the shot next to them, even though they were all standing next to each other. (00:10:28)
Burying the Past: Part 2 - S3-E24

Burying the Past: Part 1 - S3-E23
Continuity mistake: When a giant lizard man appears near the alleyway, Yugi says, "Looks like our work's not done," and stands behind Joey. When the shot cuts, Joey can be seen in the shot, but Yugi cannot be seen behind him. Then Yugi runs up to him, showing he was in front of him, instead of behind him. (00:11:38)
Continuity mistake: When Noah realises Gozaburo is in the virtual world, he says, "Father, no," and has his head faced forwards. In the next shot, his head is turned to the left. (00:05:30)

Noah's Final Threat: Part 2 - S3-E21
Continuity mistake: Just after Blue Eyes Ultimate Dragon attacks Noah, his life points go down to 8,300. When the three individual Blue Eyes White Dragons attack Noah, the life point count is displayed and it is 8,700. (00:19:13 - 00:19:48)
Noah's Final Threat: Part 1 - S3-E20
Continuity mistake: When Yugi draws Dark Magician Girl from his deck, he has two fingers pressed against the back of the card.

Noah's Final Threat: Part 1 - S3-E20
Continuity mistake: When Yugi activates Swords of Revealing Light, he has his right forearm pointed to the left so that he can insert the spell card into the duel disk slot. In the next shot, his right arm is lowered. (00:14:20)
Noah's Final Threat: Part 1 - S3-E20
Continuity mistake: When everyone realises that Noah has gone, Tea is standing behind Serenity. When the shot cuts, Tea is standing in front of Serenity. (00:09:43)
Noah's Final Threat: Part 1 - S3-E20
Continuity mistake: When Yugi draws Kaiba's card, he has a finger pressed against the back of it. In the next shot, he has two fingers pressed against the back of the card. (00:07:26)
Brothers in Arms: Part 1 - S3-E17

Merger of the Big Five: Part 3 - S3-E16

Merger of the Big Five: Part 2 - S3-E15
Continuity mistake: When Joey gets up after being attacked by Hysteric Angel, in the shot of him saying "Yeah, I've never been better," he has his arm over his face. His elbow appears to be aligned with his mouth, but when the shot cuts, it is now his wrist that is aligned with his mouth. (00:04:47)
Merger of the Big Five: Part 2 - S3-E15
Continuity mistake: When Johnson summons Hysteric Angel, in the shot of him placing the monster card on the duel disk, there is another monster card also on the duel disk. A few seconds later, after Hysteric Angel has appeared on the field, only one monster card can be seen on the duel disk, even though there should be two. (00:03:52)
Merger of the Big Five: Part 1 - S3-E14
