Pinball is a type of arcade game in which a player uses paddles (called flippers) to manipulate one or more balls inside a pinball machine. A pinball machine is a glass-covered cabinet containing a play field populated with lights, targets, bumpers, ramps, and various other objects depending on its design. The primary objective of the game is to score as many points as possible by hitting targets and making various shots with the flippers, before all balls "drain" at an exit usually situated at the bottom of the play field. Most pinball games are divided into turns (referred to as "balls", having the same meaning as "lives" in video games). The game ends when all balls have ended.
