Continuity mistake: When Bakura reveals his Shallow Grave card, his right hand is touching his duel disk. In the next shot, his right hand is at his side. (00:12:03)
Continuity mistake: Bonz's life points go from 4000 to 3500 after Bakura destroys his monster. When Bonz draws a card from his deck on his next turn, the life point display on the duel disk is back to 4000 (the first number cannot be seen, but there are three zeroes, so it is certainly not accurate). (00:13:03)
Revealing mistake: Just after the Earl of Demise destroys Snake Hair, in the shot where Bonz says "We'll see which one of us is an amateur when I do this," the cards he is holding in his hands are missing the illustrations. (00:13:08)
Continuity mistake: When Magnum walks up to Mai after she lands on Joey, her left arm has a sleeve on it. Magnum offers Mai his hand, prompting her to slap his hand away. In the close-up of her slapping his hand, the sleeve is missing from her arm before reappearing soon after. (00:17:51)

Other mistake: When Yugi, Joey and Mai show the security guards their Locator Cards, they are all shown to have seven cards in their hand, even though they are supposed to have only six. (00:04:02)

Continuity mistake: When Marik is speaking with Yugi, Joey and Tea after entering the stadium, he is wearing a duel disk on his left forearm. Seconds later, when Bakura has entered and Joey tells him he should go back to the hospital, Marik's duel disk has suddenly disappeared. (00:05:39)

Let the Finals Begin! - S2-E32
Continuity mistake: When Odion arrives at the stadium while impersonating Marik, there is a wide shot where Joey says, "I think I scared him, Yug." In the wide shot, Yugi and Joey appear to be standing ahead of Kaiba. Then, in a shot focusing on Kaiba, the two are suddenly aligned with Kaiba. Tea also changes position, going from being directly behind Yugi and Joey to being behind them on their right in between shots. (00:07:32)
Let the Finals Begin! - S2-E32
Continuity mistake: When everyone is on the blimp, there is a shot of the characters looking down at the city. In the shot, Joey and Trinity are standing side by side. When it cuts to focus on Joey and Trinity, Joey is slightly ahead of Trinity. (00:10:16)
Let the Finals Begin! - S2-E32
Audio problem: When Trinity thanks Joey for bringing her onboard the blimp, Joey says, "Just one of the many perks of being a champion." There appears to be a slight delay with Joey's mouth movements, as his mouth doesn't start moving until a second after he starts the line. (00:10:22)
The Dark Spirit Revealed: Part 1 - S2-E33
Continuity mistake: When Yugi is wondering why Bakura didn't attack with his Dark Necrofear monster, the two monster cards on his duel disk are upside down. Seconds later, when Yugi draws a card from his deck, the two monster cards are right side up. (00:17:40)
The Dark Spirit Revealed: Part 1 - S2-E33

The Dark Spirit Revealed: Part 2 - S2-E34
Continuity mistake: When Gamma the Magnet Warrior's attack is deflected back onto Yugi, two monster cards can be seen on his duel disk. The two monster cards are next to each other. But seconds later, when Bakura tells Yugi he'll see what Darl Sanctuary is capable of soon enough, there is suddenly an extra monster card zone shown in between the two cards. (00:03:04 - 00:03:36)
The Dark Spirit Revealed: Part 2 - S2-E34
Revealing mistake: When Yugi says, "My monster's attack didn't work, and I was attacked instead," there is a shot from behind Yugi that pans over to Bakura. In the shot, the Dark Magician Girl card on his duel disk can be seen moving slightly, just as it goes out of frame. (00:03:09)
The Dark Spirit Revealed: Part 2 - S2-E34
Continuity mistake: When Yugi activates the trap card Collective Powers, the Kuriboh card is on the left-hand side of the duel disk and is in defence mode. Seconds later, when he activates the spell card Exile of the Wicked, the Kuriboh card is now on the right-hand side of his duel disk and is in attack mode. (00:15:35 - 00:15:56)
The Dark Spirit Revealed: Part 3 - S2-E35
Continuity mistake: When the duel finishes, Yugi starts running over to Bakura's side of the playing field to reach him. Joey then says, "Lower that arena and get them down here," and the playing field is visible in the foreground of the shot, but Yugi cannot be seen anywhere running across it. (00:15:03)
The Dark Spirit Revealed: Part 3 - S2-E35
Continuity mistake: When everyone runs over to Bakura after the duel is over, Marik is missing from the group, despite being next to them for the entirety of the duel. Seconds later, when Tristan begins to carry Bakura, Marik suddenly appears next to the group. (00:15:10 - 00:15:33)
The Dark Spirit Revealed: Part 3 - S2-E35
Revealing mistake: When Yugi is talking with Pharaoh after the duel, in the shot where Yugi says, "Together, we'll figure out the secrets of your ancient past," the Millennium Puzzle appears to be drawn a lot narrower compared to every other time it is shown. (00:16:18)
The Dark Spirit Revealed: Part 3 - S2-E35
Continuity mistake: When Tea is left alone with Bakura, in the shot of the other characters walking out of the bedroom, one of the chairs next to the bed is shown at a rotated angle. In the next shot, the chair doesn't appear to be rotated at all. (00:19:25)
The Dark Spirit Revealed: Part 3 - S2-E35
Plot hole: The episode ends with the reveal that Tea has the Millennium Ring and is now possessed by Marik. The last time the Millennium Ring was shown, it was thrown by Bakura at the end of the duel on the playing field. There is no way Tea could have retrieved the Millennium Ring from the playing field without the other characters noticing, seeing as how she was with them the entire time while they took Bakura back to his bedroom and had nowhere to hide it. (00:19:34)
