Naturally, you'll want to start with the original series that starts it all — "Yu-Gi-Oh! Duel Monsters." This takes you through the journey of Yugi and his friends as they attempt to learn more about the mystery of his Millennium Puzzle. However, hardcore fans will know there's technically a season before this one known to enthusiasts as "Yu-Gi-Oh! Zero." While it takes place before the events of "Duel Monsters," it really doesn't have anything to do with what comes after, so plenty of people skip it for good reason.
Once you get through "Duel Monsters," you have "Yu-Gi-Oh! GX" to enjoy. This takes place about 10 years after the events of the first series, only this time, the protagonist is Jaden Yuki, who attends a Duel Academy to become the next Duel King. They take card games pretty seriously in this universe.
After that, you have "Yu-Gi-Oh! 5D's," which introduces the concept of Synchro Monsters as well as performing duels on motorcycles in the far-off future. Next, there's "Yu-Gi-Oh! Zexal," a show following Astral and Yuma as they attempt to collect the 100 number cards required to restore Astral's memories. The distant future is popular for "Yu-Gi-Oh!" spin-offs, as evidenced by "Arc V."
The final two pieces of the puzzle, in their respective order, are "Yu-Gi-Oh! VRAINS" and "Sevens," both of which put their own special spin on the franchise's format. There you have it. The chronological order also happens to be (for the most part) how the shows aired in the first place. You can see how they all connect and lead into one another while enjoying one intense card match after another.
