Pinball games are a family of games in which a ball is propelled into a specially designed table where it bounces off various obstacles.

To play pinball, start by pulling the plunger at the front of the machine to release the ball. Then, use the flippers to hit the ball by pressing the buttons on jac. Try to aim the ball toward the two arcs throughout the machine, which will bounce the ball and earn you points.
