Continuity mistake: When Yugi is telling Tea that he was talking to the spirit of the Millennium Puzzle, his right hand is holding onto the puzzle with only his fingertips. In a close-up of the puzzle, his entire right hand is holding onto it.(00:01:57)
Continuity mistake: When Yugi is looking at his Millennium Puzzle in the mirror, his right hand is holding onto it. His index finger appears to be positioned an inch below the top of the puzzle, level with the eye. Then it cuts to a shot of the mirror where his index finger is closer to the top of the puzzle. His finger moves back down when the shot cuts again.(00:01:25)
Continuity mistake: When Tea greets Solomon while he is sweeping, in the shot of Tea saying "Good morning, Mr Moto," the broomstick he is holding is held at a rotated angle. When the shot cuts to Solomon, the broomstick is held more upright and is closer to his head.(00:01:08)
Revealing mistake: When Peter breaks into Joanna's apartment, he breaks the chain lock attached to the door. The final chain piece attached to the chain on the wall and the final chain piece attached to the chain on the door both appear intact, even though they would have been snapped when he broke the door chain.(01:40:45)
Continuity mistake: After the duel, Devlin apologises to Yugi for accusing him of cheating. The first shot shows a game board on a table, which features black squares and includes thin white lines separating the squares. Then it cuts to a wide shot of the room, and the white lines now appear to cover most of the game board.(00:17:40)
Continuity mistake: After Solomon says "Have faith, Yugi," it cuts to a wide shot of the duelling room where Devlin's fangirls are cheering him on. In the shot, Devlin's hands are at his side. The shot then cuts to focus on Devlin, where his right forearm is suddenly raised.(00:12:16)
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)
Continuity mistake: When Solomon is watching Yugi duel, in the wide shot, there is a crowd of people behind him. There is a kid behind him standing over the edge of a tile on the floor; this kid has grey trousers and white shoes, and there is another kid next to him wearing dark grey trousers and grey shoes. When it cuts to a closer shot of Solomon, the kid standing over the edge of the tile is wearing purple trousers and grey shoes, and the other kid is wearing light blue trousers and white/black trainers.(00:08:16)
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)
Continuity mistake: When Devlin tells Yugi, "All that stands between you and defeat is the time that it takes for my Automater to spit out the next rare black dice," the bracelet on his right arm is shown to have three loops. It then fades to a closer shot of Devlin, and the bracelet has two loops.(00:12:04)
Continuity mistake: In the flashback of Devlin creating the Dungeon Dice Monsters game, there is a close-up of his keyboard. A blue wire can be seen attached to the keyboard and is pointed to the left. Two shots after this, the blue wire is pointed straight forwards.(00:14:59)
Continuity mistake: After Yugi rolls the two matching dice (but is unable to summon a monster due to their levels not being the same), Devlin rolls three dice. When the black dice land on the board, it is not touching the pink light. When the shot cuts, part of the black dice is over the pink light.(00:08:42)
Continuity mistake: When Yugi realises his dice only have one summon crest, Devlin says, "Of course, if you had, it'd have been a very strong monster," and puts his right hand over his chin. In the next shot, his hand is away from his chin.(00:06:15)
Continuity mistake: When Devlin rolls the dice on the first turn, in the shot of the three dice landing, the green die lands with an arrow on the facing up side. When it cuts to a close-up of the green die, a star with the number two on it is now on the facing up side.(00:03:38)
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)
Continuity mistake: When Goblin Attack Force switches to defence mode after it attacks, Devlin has four cards in his hand. On Devlin's next turn, just as he goes to summon Gradius, there are six cards in his hand. Even if he drew one card at the start of his turn, there is still an extra card.(00:14:44 - 00:15:18)
Continuity mistake: When Joey summons Goblin Attack Force, there are four cards in his hand. Seconds later, when Joey says, "and next turn it's zero, and then you're gonna close your shop down for good," he has three cards in his hand.(00:14:20 - 00:14:45)
Continuity mistake: When Joey says he has more talent than Devlin, Tristan says, "If you count talking with food in your mouth a talent," to which Joey replies, "Didn't you catch any of my moves in Duelist Kingdom?" At this moment, Tristan is shown leaning to the left. When the shot cuts, he is standing upright.(00:05:15)
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)
