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)
Continuity mistake: Joey has a bowl of soup on the dinner table in front of him when he is eating from the massive plate of food. When the shot cuts, the bowl is now more to the right, and the massive plate of food is directly in front of him. (00:01:13)
Continuity mistake: When Kaiba is standing outside Mokuba's cell, his body is angled slightly to the right, and then he turns his head further to the right, so that he can face Pegasus. When the shot cuts to focus on Pegasus, his body is directly facing Kaiba. (00:01:03)
Continuity mistake: In the flashback of Tea working at the fast food restaurant, she slams a tray of food down on the table Yugi and Joey are sitting at. There are two milkshakes with straws in them, both of which are positioned at an angle to the left. When the shot cuts, the straws are at different angles. (00:04:32)
Continuity mistake: When Kaiba says "I don't need to see your hand," he lifts up the two cards in his hand. The card on the left appears to be placed on top of the card on the right. But in a close-up of his hand, the card on the right is now placed on top of the card on the left. (00:07:30)
Continuity mistake: Whilst Kaiba is standing on the edge of the castle, in the overview shot of him saying "Of course, if you don't surrender, I might be hurt," Joey can be seen standing ahead of Tea. Tea then says "Stop it, Kaiba," and she is suddenly ahead of Joey. Then, in the shot after that, they are side-by-side. (00:13:07)
Double Trouble Duel, Part 2 - S1-E20
Continuity mistake: After Magical Labyrinth has been activated, the maze on the duel field begins to rearrange itself. There is a shot of the duel monsters on the field, where Dark Magician has his arms crossed. When the shot cuts, his arms are lowered. (00:06:00)
Double Trouble Duel, Part 3 - S1-E21
Continuity mistake: When Yugi says, "It's going to be up to Joey to keep us in this duel, and I know he won't let us down," Joey begins to lift a card from his deck. In the close-up of Joey's hand, the card is raised slightly, but when the shot cuts, the card hasn't been raised. (00:12:00)
Double Trouble Duel, Part 1 - S1-E19
Revealing mistake: When Joey places his Ax Raider card on the duel mat, the card appears to be entirely yellow and missing the illustrations usually shown on the card. (00:15:20)
Double Trouble Duel, Part 1 - S1-E19
Revealing mistake: In the overview shot of Dox placing Jirai Gumo face down, all the cards in his hand appear to be missing the illustrations. (00:16:08)
