If regular air hockey games such as Touch Hockey are too bland for you, then you could try installing the exceptionally popular Glow Hockey Free on your iPhone.
The game follows all the usual rules of air hockey, but the twist is that all the graphics light up. Glow Hockey Free is visually pretty impressive, and the colorful neon table, pucks and paddles are very authentic. In fact, they might even distract you a little from the gameplay by being slightly too bright!
Glow Hockey is very easy to play. Just hold your finger somewhere near the paddle and drag it around. There are three levels of difficulty in this free version of the game, and the hardest level can be pretty challenging.
Overall though, the lack of two player mode in Glow Hockey Free gives the game a very limited shelf life. Playing against the computer opponent quickly gets very boring.
If you're looking for some air hockey fun without having to drop in some tokens and find an opponent, Glow Hockey's a fun alternative
