In Chopper, you have to keep your helicopter in the sky as long as possible. Be warned, once you start the game, it starts immediately! If you don't work right away to keep your chopper in the air, it will hit the ground in a few seconds. To control your helicopter, use your mouse to click. Click higher on the screen to make your helicopter move up. Click lower on the screen to make it fly down. There are lots of obstacles in the way, and you need to steer around them if you don't want to smash your helicopter to smithereens.
