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. After finishing his turn, Tea, Tristan, and Bakura discuss the move, and when Bakura says, "Which would let Joey counterattack with his black skull," Garoozis has disappeared from the field. (00:05:20 - 00:05:58)
Best of Friends, Best of Duelists, Part 2 - S1-E34
Continuity mistake: When Joey draws Baby Dragon from his deck, there is a split screen shot of Joey smirking at Yugi. In this shot, the card is held at a tilted angle. But in a wide shot, the card is held at an upright angle. (00:12:35)
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)
Duel Identity, Part II - S1-E30
Other mistake: When Mai starts explaining why she lost to Joey, two copies of the trap card Shadow of Eyes and two copies of the monster card Harpie Lady can be seen on her duel mat, even though she has only played one of each. (00:02:57)
Duel Identity, Part II - S1-E30
Other mistake: When Mai tells Yugi, "You just made your final mistake," it cuts to an overview shot where Yugi's life point count is 1350, even though at this point in the duel it should be 300. (00:06:03)
Duel Identity, Part II - S1-E30
Revealing mistake: When Yugi and Pharaoh have a brief heart-to-heart, it cuts back to the duel field with a shot from behind Yugi saying, "Maybe you're right." At this moment, the cards Yugi is holding are missing the illustrations. (00:05:02)
Continuity mistake: When the finalists are being congratulated, in the wide shot, Yugi and Mai are two feet apart from each other. When it cuts to a closer shot of them, they (and the food and drinks on their side of the table) are closer together. (00:01:17)
Continuity mistake: At the dinner table, there is a knife, fork, and spoon placed on a napkin in front of Yugi. In the shot focusing on Yugi and Mae, the utensils are placed over the entirety of the napkin. A couple of seconds later, when everyone says "huh" after being told about the entry cards, the utensils only appear to be placed over half of the napkin. (00:01:21)
Continuity mistake: When Yugi and Mai realise they are going to be duelling each other, whilst Yugi is saying "Looks like it's you and me, Mai," he is holding the piece of paper with the letter A. At first, his hand appears to be covering the entirety of the bottom side of the paper. In the next shot, the left bottom side of the paper is uncovered. (00:03:00)
Continuity mistake: When Solomon says, "Every soul he traps in the shadow realm increases his strength," the card of Solomon that Yugi is holding is held with two hands in the close-up shot but only one hand when the shot cuts. (00:10:18)
Revealing mistake: When Tristan finds the rope, it is wrapped around two hooks on a wall. In the shot of Tristan removing the rope from the hooks, there is a minor animation error, where some of the rope loops are drawn in front of the hooks instead of behind them. (00:08:55)
Champion vs. Creator, Part I - S1-E26
Continuity mistake: When Mai opens the door with the star chips, in the shot of her saying "Voila", Joey can be seen standing next to Yugi. Then it cuts to Yugi saying "At last, we're finally at the castle" and Joey cannot be seen standing next to him. (00:01:33)
Champion vs. Creator, Part II - S1-E27
Continuity mistake: When Blue-Eyes Toon Dragon is summoned to the field, Pegasus' life point count on the platform is displayed as 1600. Seconds later, in the overview shot after Pegasus says "I've made him much more cuddly," his life point count is 1400. (00:05:45 - 00:06:07)
Continuity mistake: Tristan has a knife on the dinner table that is positioned at a 2 o'clock direction whilst eating, but when it cuts to a wide shot, the knife is closer to a 3 o'clock direction. The knife also moves closer to the edge of the table in the wide shot. (00:01:12)
