Clash in the Coliseum: Part 3 - S3-E34

Clash in the Coliseum: Part 3 - S3-E34
Continuity mistake: Just after Kaiba activates Command Silencer, in the shot of Yugi asking "What is that?", his hands are lowered, but in the next shot, his hands are on his ears. (00:05:53)
Clash in the Coliseum: Part 3 - S3-E34
Character mistake: When Slifer the Sky Dragon's attack points go from 2000 to 3000, Kaiba tells Yugi, "But now that your turn is over, Obelisk regains its full strength," but Yugi's turn isn't over; it only just started, as shown by him activating Pot of Greed shortly after. (00:05:08)
Clash in the Coliseum: Part 2 - S3-E33
Continuity mistake: Just after Obelisk the Tormentor has been summoned to the field, in the shot of Yugi saying to himself, "I hope I can hold my own against the power of Obelisk," his right forearm is raised and his hand is closed into a fist. When the shot cuts, his forearm is lowered, and his hand is not closed into a fist. (00:19:26)
Clash in the Coliseum: Part 1 - S3-E32
Continuity mistake: When Kaiba draws his Obelisk the Tormentor card, he is holding it with two fingers against the back. One finger is close to the bottom of the card and the other is closer to the middle, but in the next shot, his fingers are nearer to the top. (00:06:35)
The Darkness Returns: Part 4 - S3-E31
Continuity mistake: When the Millennium Necklace is glowing while in Yugi's hand, in the shot where he says, "Maybe the Millennium Necklace is telling me Joey's gonna be okay," his fingers are spread apart. When the shot cuts, his fingers are closed together. (00:15:16)
The Darkness Returns: Part 4 - S3-E31

The Darkness Returns: Part 3 - S3-E30
Continuity mistake: When Marik draws the Machine Duplication card from his deck, he has three fingers pressed against the back of the card. When it cuts to a close-up of the card, he only has one finger pressed against the back of it. (00:05:27)
The Darkness Returns: Part 2 - S3-E29
Continuity mistake: When Baby Dragon is on Joey's field, the monster card on his duel disk is positioned at a rotated angle with the artwork facing to the left and the wording facing to the right. But later in the episode, when Joey summons Jinzo, in the shot of the Jinzo card being placed on the duel disk, the Baby Dragon card is facing the opposite direction, with the artwork facing to the right and the wording facing to the left. (00:05:37 - 00:13:07)
The Darkness Returns: Part 1 - S3-E28
Continuity mistake: When Joey stomps his foot on the floor, a line can be seen beneath his foot, showing where the tiles were placed. In the next shot, the line on the floor disappeared. (00:17:03)
The Darkness Returns: Part 1 - S3-E28
Continuity mistake: On Joey's first turn, after drawing the Alligator Sword card from his deck, he looks at the other five cards in his hand. At first, his hand is at a horizontal angle, but in a close-up of the cards, his hand is at a vertical angle. (00:07:56)
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
Continuity mistake: When Kaiba draws the Blue-Eyes White Dragon card, he has one finger on the back and one finger on the front side, with his fingers positioned near the middle of the bottom side. Then, when the card is revealed in the close-up, he has two fingers on the back and his thumb on the front, which are positioned on the right-hand side of the card. (00:11:13)
Burying the Past: Part 2 - S3-E24
Continuity mistake: When Kaiba draws the Pot of Greed card from his deck, he has two fingers pressed against the back of the card and his thumb pressed against the front. But in a close-up of the card, there is one finger pressed against the back and one finger pressed against the front. (00:09:49)
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)
Burying the Past: Part 1 - S3-E23
Revealing mistake: When Kaiba tells Gozaburo that he's about to send four pieces of Exodia to the graveyard, Gozaburo asks, "Then what are you waiting for?" and raises his forearms. When he does this, the cards in his hands are missing the illustrations. (00:10:14)
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)
Continuity mistake: When Noah is explaining that there are no real bodies in the virtual world, Joey is standing behind Devlin. Then, in the next shot, where Joey says "I don't get it," he is standing in front of Devlin. (00:04:35)
