3000 Years ago marked the turning point of an Egyptian Dynasty; the Pharaoh’s spirit was sealed inside one of the ancient relics, the Millennium Puzzle, after saving the kingdom from an enemy army. Now, in the present age, the Millennium Puzzle is found by a young boy, Yugi Mutou, who unlocks the spirit of the puzzle and is possessed by the sprit of the old Pharaoh, who lost all of his memories from his old life.
