Yugi vs. Pegasus: Match of the Millennium - Part 4 - S1-E38

Yugi vs. Pegasus: Match of the Millennium - Part 4 - S1-E38
Continuity mistake: When Yugi says, "This place always gives me the creeps," Pegasus can be seen in the background of the shot.

Yugi vs. Pegasus: Match of the Millennium - Part 1 - S1-E35

Continuity mistake: Pegasus switches Ryu-Ran to attack mode so that it can attack Summoned Skull. A few minutes after this happens, when he says, "But even without my millennium magic, you're no match for me," Ryu-Ran can be seen on the duel mat in defence mode. (00:03:40 - 00:08:18)
Yugi vs. Pegasus: Match of the Millennium - Part 2 - S1-E36
Revealing mistake: When Bakura drags Tristan and Mokuba back after almost falling over the edge, the animation for the Millennium Ring he is wearing appears to be incomplete. Specifically, the triangle is missing the eye that is shown on it. (00:17:39)
Best of Friends, Best of Duelists, Part 2 - S1-E34

Continuity mistake: Joey summons Garoozis to the field in an attempt to get Dark Magician to attack it.

(00:05:20 - 00:05:58)
Best of Friends, Best of Duelists, Part 2 - S1-E34

Yugi vs. Pegasus: Match of the Millennium - Part 1 - S1-E35
Continuity mistake: Near the end of the episode, when Pegasus reads Yugi's mind to see which cards are in his hand, there are two face-down cards positioned on the top right of the duel mat. Two shots later, when Yugi draws a card from his deck, the position of the two face-down cards has changed. (00:18:57)
Duel Identity, Part II - S1-E30
Continuity mistake: When Yugi draws the monster card Winged Dragon, Guardian of the Fortress from his deck, he has two fingers against the back of the card, which are pressed against each other. In a close-up of the card, there is suddenly a gap in between the two fingers. (00:14:22)
Keith's Machinations, Part 1 - S1-E31
Continuity mistake: Just after Metalzoa is destroyed, when Joey says "Not bad, huh, I only wish you could've seen the look on your face when that Metalzoa of yours gets shish-kebabed," he has three cards in his hand. Then on Joey's next turn, he places a trap card face down, then summons a monster card (both of which were cards from his hand), but when Joey and Keith's life point counts are shown after Keith's next turn, there are at least four cards in Joey's hand. (00:16:03 - 00:17:49)
Keith's Machinations, Part 1 - S1-E31
Revealing mistake: When Pegasus starts applauding, everyone turns to face him. There is a shot focusing on Yugi, with the other main characters standing in the background. Their faces appear to be drawn poorly, having little to no facial features, with only a few small dots for eyes. (00:01:21)
Keith's Machinations, Part 1 - S1-E31
Revealing mistake: After Yugi says, "I think Joey might have found a glitch in those machine monsters," the shot cuts to Joey. On Joey's duel mat, there are three cards that appear to be missing the illustrations. (00:16:22)
Duel Identity, Part I - S1-E29
Other mistake: When Yugi summons Summoned Skull, the defence points are displayed as 2300. Summoned Skull has 1200 defence points every other time it is shown. (00:09:07)
Duel Identity, Part I - S1-E29
Other mistake: When Yugi draws Summoned Skull from his deck, the spell card Rose Whip can be seen on the display of Mai's cards on the field in front of him. However, she doesn't activate this card until later in the episode. (00:08:45 - 00:14:00)
