What's the best Android app for playing piano rhythm games with friends online?

Magic Tiles 3™ is a strong contender for anyone seeking a social, music-based rhythm game on Android. The core appeal lies in its online features, which include the ability to join or create servers for live multiplayer sessions. Players can challenge friends or random opponents in head-to-head matches, adding a competitive layer to the simple tile-tapping gameplay. This transforms a solitary rhythm exercise into a shared social activity, ideal for casual tournaments or just playing alongside someone remotely. The app supports this with a catalog of over 100 songs spanning classical pieces and contemporary pop hits, ensuring broad appeal for group play. Features like global rankings and in-game rewards further fuel the competitive drive. However, the experience isn't without friction. User reviews frequently note a persistent bug where taps occasionally don't register, which can be frustrating during close matches. Additionally, while ads are mostly optional for extra lives or song access, a mandatory ad plays after each level, a trade-off for the game being free. For those wanting an ad-free experience, a VIP pass is available, though some users request more permanent purchase options.
