The idea is from Rubik`s cube puzzle. The only way to activate the mp3 player on is similar to playing with the Rubik`s cube puzzle, by solving each layer has a specific function such as play, pause, forward or back. And of course the only way to turn it off is by completing it. Users can now listen to the music while having fun.
