Continuity mistake: When Tea goes into Yugi's room, there are cards on the desk. The cards (specifically the cards around his deck) change position when it cuts to a closer shot of the desk. (00:14:55)
Revealing mistake: When Yugi gets off the boat and sees everyone standing on the dock, Solomon can be seen to the left of the shot with his right arm randomly raised in the air. There is no reason for him to be doing this and he remains completely still while doing so. There is a painted-over freeze frame a few seconds later which shows both of his arms in the air and cheering, which may explain why his right arm was raised in the earlier shot even though he wasn't cheering at that point. (00:20:19)

The Final Duel: Part 2 - S5-E38
Other mistake: Yugi activates Mirage Spell, which allows him to gain life points equal to the amount that Slifer the Sky Dragon was going to take from Valkyrion the Magna Warrior. Yugi's life points are then shown going from 850 up to 3400. However, Yugi's life points before this were 1400, not 850. He even says it increases his life points by 2000. (00:10:08)

The Final Duel: Part 3 - S5-E39
Continuity mistake: When Devlin suggests that Yugi realises there's no way he is going to win, Solomon says, "Not a chance." At this moment, Bakura is standing in front of Solomon, but when the shot cuts, Bakura and Solomon are standing side by side. (00:12:53)
The Final Duel: Part 3 - S5-E39

The Final Duel: Part 4 - S5-E40
Continuity mistake: Tristan says all Yugi can do is strengthen his defenses, to which Joey replies, "Nah, I'll bet he's doing more than that." After he says this, Tristan and Tea turn their heads to face Joey, but when the shot cuts, Tristan is looking straight forward at Yugi. (00:02:45)
