Is it possible to transfer games from one Apple ID to another?

While it is not possible to transfer games from one Apple ID to another, what you can do is sign into your old Apple ID and download your games, then wait 90 days (since that is the amount of time one must wait before signing out into an Apple ID once signed in). Once that 90-day time limit is over, sign out of your old Apple ID and sign into your new one. Keep in mind that ICloud save data, in-app purchases, or Apple ID funds from your old Apple ID cannot be transferred over, and that your Apple Arcade membership (if you have one) will need to be renewed along with any in-app purchases, and any games no longer on the App Store can’t be redownloaded once deleted.
