If you have noticed, all Tap Tap games are no longer available from the Apple App Store (even in the Google Play Store) including the popular "Tap Tap Revenge 4". According to the company (Tapulous, Inc.), “it no longer makes sense for us to maintain the Tap Tap franchise” due to the changing mobile and music markets. All games have been removed from the Apple App Store and they've also shut down the servers.
But good news for the Jailbroken iPhone/iPad users, you can still get it and even for free on AppCake, App Time Machine, Pandaapp, etc. Don't be happy yet because after installing and opening the app, you can get this error: "The requested URL was not found on this server." Well, you can't get this error on other Tap Tap games like "Tap Tap Revenge Tour." But since, Tap Tap Revenge 4 is our favorite, here's a very simple trick to make it works! I've found this trick by myself and I was really shocked when it works, perfectly. The trick is, before opening the app, just turn off the WiFi and there we go! You will now enjoy playing Tap Tap Revenge 4 on your iPhone/iPad.
The trick will also works on other Tap Tap games like Katy Perry Revenge, Tap Tap Radiation, etc. Enjoy playing! And for Android users, yes it will work too!
