Piano by Yokee is a piano-playing game where you use your touchscreen to play all kinds of songs, from Fur Elise by Beethoven to Paparazzi by Lady Gaga or Rehab by Amy Winehouse. In total there are more than 100 songs at your disposal.
In the beginning, not all of them will be unlocked, but as you play, you'll be able to 'buy' new ones with the game's currency. You can also buy this 'ingame' currency with real money, but it's not necessary.
Gameplay in Piano by Yokee is simple: you'll see colored bubbles coming down on the screen, and you'll have to tap them when they are exactly in the center. If you do it right, you'll notice the song is played correctly, but if you don't, then you'll hear the missing notes.
Piano by Yokee is a fun, super gratifying music game that lets you interpret some of the greatest classics in music in a very simple and entertaining way.
