The Fandom Post is reporting that RetroCrush has added the first five seasons of the Yu-Gi-Oh! series to its service. The episodes are available in English-dubbed form.
Yu-Gi-Oh! is described as:
Meet Yugi and his best buds Joey, Tristan and Téa. They share a love for the newest game that’s sweeping the nation: Duel Monsters. Legend has it 5,000 years ago, ancient Egyptian Pharaohs used to play a magical game very similar to Duel Monsters. This ancient game involved magical ceremonies, which were used to foresee the future and ultimately decide one’s destiny. They called it the Shadow Games. Since the game used so many magical spells and ferocious creatures, it wasn’t long before the game got out of hand and threatened to destroy the world.
