In the Name of the Pharoah - S5-E35
Continuity mistake: When the Pharaoh realises his name has appeared on the cartouche, he has two rings on his fingers. Then during the same shot, when he says "Yugi, it worked," he curls the two fingers he is wearing his rings on even further, obscuring them from view. The rings are shown in view again in the close-up of the cartouche. (00:12:55)
