I totally get how annoying that can be. Game Center ends up being cluttered with random old games you barely touched, and unfortunately, there's no simple "delete" option to clean them out. The best thing you can do is delete the actual apps from your device if they’re still installed—that way they won’t keep showing up as recently played. Sometimes signing out of Game Center and then signing back in can help refresh things a bit, though it’s not guaranteed to clear everything. Some games like flying chess teen patti have settings that let you disconnect from Game Center, so it’s worth checking within the game itself if you still have it. But yeah, Apple doesn’t currently give you full control over your Game Center history, which is super frustrating. Hopefully, they update it someday and let us clean it up properly.
