Dungeon Dice Monsters: Part 4 - S1-E49
Revealing mistake: When Yugi tells Devlin, "There, I'll add four attack crests from my Crest Pool to the two attack crests I just rolled, giving my knight a total of six attack crests," part of his neck can be seen passing over the lanyard holding up the Millennium Puzzle. (00:08:48)
Dungeon Dice Monsters: Part 4 - S1-E49
Revealing mistake: At the start of the episode, whilst Devlin is saying "Nice try, Yugi, but none of your monsters can withstand the force of Orgoth the Relentless," he is shaking three dice in his right hand. Aside from the green and red colouring, the dice are virtually blank. The crests have not been drawn onto them. (00:02:00)
Dungeon Dice Monsters: Part 2 - S1-E47
Revealing mistake: When Devlin is typing into the keyboard, none of the keys are shown moving when he presses them. (00:14:59)
Dungeon Dice Monsters: Part 1 - S1-E46
Revealing mistake: On the turn, Devlin summons Gradius. Just after he removes the Gradius card from the cards he is holding, he lowers his left hand. The illustrations are missing from the cards in his left hand when he does this. (00:15:18)
Dungeon Dice Monsters: Part 1 - S1-E46
Revealing mistake: When Duke Devlin is showing the girls how to play the dice game, he places six dice on the table. In the shot after he says "Showtime," there is a shot above the characters and the dice appear to be drawn in different sizes, instead of all six being the same size. (00:04:26)
Legendary Heroes: Part 1 - S1-E43
Revealing mistake: In the arena, in the wide shots, the spectators are cheering, but none of them are moving. They have their arms raised in the air, but they appear to be completely motionless. (00:18:27)
The Ties of Friendship - S1-E42
Revealing mistake: When Solomon puts the water bottle to Hawkins' mouth, Hawkins starts drinking from it. The mouthpiece doesn't actually go inside Hawkins' mouth; it is just lightly pressed against his lips, but he has no difficulty drinking from it. (00:17:57)
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)
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)
Keith's Machinations, Part 1 - S1-E31
Revealing mistake: When Joey is running back to his room to search for the key card, there is a shot of him running down the hallway, but the background doesn't appear to match his bodily movements. He is shown running at fast speed, with his body positioned in the centre of the frame during the shot, but the background is shown pulling back at a slow speed, even though the background should be pulling back much quicker for it to be consistent with Joey's running. (00:04:46)
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)
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)
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)
Revealing mistake: When Joey and Tristan are eating, Joey is shown reaching for foods placed in front of him. When he does so, his arm appears to brush against a spoon on the table, but the spoon appears to be unaffected by Joey's arm. (00:01:11)
Champion vs. Creator, Part II - S1-E27
Revealing mistake: When Blue-Eyes Toon Dragon destroys Rude Kaiser, Kaiba is shown with his left hand clenched. However, he is holding his cards in his left hand, and they do not appear to be affected by his hand being clenched. (00:06:29)
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)
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)
Revealing mistake: When Ghost Kaiba has summoned Blue Eyes White Dragon to the field, after Mokuba says, "That means what they said, could it be true," there is a shot from behind Yugi where we can see the cards in his hand and on his field appear to be blank and have no illustrations. (00:10:28)
Revealing mistake: When Pegasus is looking at Yugi's result stats, in the shot of him saying "Wonderful. I expected no less," the outline of his blazer sleeve can be seen overlapping with the wine glass on the table. (00:03:15)
The Heart of the Cards - S1-E1
Revealing mistake: When Kaiba shows Solomon the briefcase full of cards, there is one card with 1600 attack points and 1800 defence points. The defence points of the card appear to be a lot lighter than the card's attack points, as well as the attack and defence points of the other cards. (00:04:52)
