Revealing mistake: When Solomon is tending to Mokuba in the hospital, there is a wide shot where he walks over to a sink. The sink is reflected in a mirror on the wall, but the tap appears to be smaller in the reflection compared to the tap shown on the sink. (00:08:41)
Character mistake: Just before Yugi summons Kuriboh, he says, "I'll place one card face down," but is then shown placing the Kuriboh card on his duel disk. Then he says, "I will summon Kuriboh," but is shown placing a card face down in one of the spell/trap card slots. (00:04:44)
Other mistake: When Yugi draws the Beast of Gilfer card, there is a shot focusing on Yugi, which then pulls out to reveal Kaiba looking at him. In the shot, the Magnet Warrior card can be seen on Yugi's duel disk in attack mode, even though it should be in defence mode. This monster remains in attack mode for the rest of the duel. (00:03:35)
Continuity mistake: When Lumis says to Yugi, "As soon as your life points reach zero," the life point count can be seen on Yugi's duel disk. The number 4000 appears to cover the entirety of the small screen displaying the life point count. But in a close-up of the small screen, there appears to be an inch on both the left and right-hand sides of the screen that the life point count doesn't cover. (00:03:20)
Other mistake: When Yugi suspects that the card Lumis placed face down is a trap card, the spell card Mask of the Accursed that Lumis just activated can be seen in the monster card zone on Yugi's duel disk. This card should not be in the monster card zone as it is a spell card and should be in the spell/trap card slots. (00:03:03)
