Vortex is an iPod game created by Apple Inc. and Kabloom Games. It is an Arkanoid/Breakout clone with a top-down perspective and bricks arranged in a circular layout.
Vortex is similar to Arkanoid/Breakout, in which you use a ball to destroy bricks. However, the bricks are arranged along the inside of a cylinder. You use the click wheel to move the paddle around the cylinder to control where the ball goes.
