The Good: Piano Tiles has simple controls, a charming soundtrack, and incredibly addictive gameplay. The Bad: The piano sounds can be distracting while playing. The Bottom Line: Piano Tiles is the perfect mix of simplicity and addictive gameplay that's easy to learn, but incredibly challenging to get high scores. Piano Tiles (iOS) or Don't Tap the White Tile (Android) are different names for the same game on the two major smartphone platforms. Having different names for the same app is a bit confusing, especially for a such a simple, but incredibly addictive touch game that requires lightning fast reflexes.Piano Tiles is another runaway hit in the vein of popular games like Flappy Bird in that it came out a little while ago, but suddenly shot to the top of the App Store charts. After a couple of rounds, I quickly saw why, because it's so easy to learn, but getting high scores becomes something of a mini-obsession.Same formula, different game modesThe basic concept behind Piano Tiles is simple. A grid with white and black tiles scrolls down your screen and your job is to touch all of the black tiles without making mistakes. As you hit tiles, you can here piano keys playing along with the action. It sounds easy, but with game modes that have you racing against the clock, and others that see how many tiles you can touch as they come at you faster an faster, it quickly grabs your attention.
