BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
There's really not much too this game and you have very little control over what's happening. Simply drop bombs on the boulders from the various planes you're flying. But since you have no control over the height and speed of your various planes, all you're doing is hitting a single button over and over again to drop bombs in order to hit as many boulders as possible. This game might be slightly more fun with a second person; but I'm not sure how this game could have been fun in the 70s let alone by today's standards!
