Reinventing Air Hockey Games - Any Suggestions? Traditional Air Hockey games get boring after some time.

I am developing an Air Hockey game for use on the iPad, and this is my question:Traditional Air Hockey games on touchscreen phone and in real life get boring after some time. Hence, is there anything that can be done to improve the game to make it more exciting and more addictive? For example, we can add distractions to the game while the user is playing on the phone. It's irritating, but also makes the game more challenging.Another idea is to add obstructions in the playing field to prevent the player(s) from scoring, making the game much more challenging. Changing the looks of the game can also help, such as Tron-inspired pucks and mallets, and even glowing trails that follow the puck around. So, what are your suggestions? I would definitely like to hear them. Thanks in advance!
