Yu-gi-oh- Gx Episode 163 -
Wait, maybe I'm confusing with the total number. Let me verify. The main Yu-Gi-Oh! GX series has 130 episodes. There's also a sub-series called "World of the Memories," which has about 30 episodes, but those are more of a recap or side stories. So episode 163 would actually fall into the World of the Memories part.
