Make sure both difficulty switches are set to B. Grand Prix by Activison for the Atari 2600 is a nicely challenging racing game that keeps you focused on one thing, finishing your race in the fastest possible time. Getting acquainted on how to play Grand Prix by Activision is mostly by trial and error. You press and hold the button down to gain speed for acceleration and tap your joystick to the left to apply the brakes. You steer your car by pointing your controller up or down to maneuver past the slower race cars and other hazards in the game. It is a good idea to remember the car patterns as you progress through each race from start to finish. You could even try mapping out a diagram of how the cars appear in each lane, so that you can navigate the course more easily. You'll then have a better idea of when each car will appear, so that you can avoid a crash, and know just were to squeeze between them. You also need to know the position of each oil slick as they are hazards in skidding into things and result in slowing the pace of your speed and over all time at the end of the course. This way of practicing will ensure that your finish time will be better and better with each run. Once you get the hang of the race car patterns, if you do collide with a slower race car, it will slow your speed down dramatically. Rather than continuing to finish the race, just reset the game and start over if this is a short race like on game 1. Grand Prix by Activision for the Atari 2600 has several courses to choose from, and each successive course offers another level of difficulty. Your game selection will be indicated by the level with the numbers 1-4 at the bottom of the screen below your game timer. 1 is the easiest and 4 is the most difficult. The first course being the easiest, with the shortest amount of time to complete. The next three game numbers have bridges that you must cross as a part of the race track difficulty, and are also longer in distance. There is no warning on when these bridges will appear, other than the precursor of a grouping of more than one oil slick together. So it's in your best interest to be prepared to be in the center of the track just in case a bridge appears. There is another way to know if you are about to encounter another bridge. If you have collided with any cars through your race close to that bridge, those cars will suddenly slow down. You then know that a bridge is coming shortly after.
