The ball accelerates based on the momentum of each tilt and bounces off walls naturally. The player may score goals, and a label counter is provided to keep track. In addition, the player may control Lionel Messi by touching the screen along Messi's x-axis. Messi plays defence; if he touches the ball, it rapidly accelerates in the opposite direction. For more challenging gameplay, turn the device upside down and use Messi for offence in a "penalty-kick" simulation. Note: this application requires an iOS device to run properly. The simulator does not have an accelerometer.
