Indy 500

In the race variations, an invisible line down the center of the screen is used to count laps. You can fool the computer by driving small circles in the center.

If you don't have the driving controllers but have a keypad controller (the touch pad with Star Raiders and children's controllers will work too) you can still play. Pressing 0 and # simultaneously gives you gas. To turn 90 degrees clockwise, press and hold 5, press and hold 2, release 5, release 2. Do the reverse to turn counter-clockwise.
