Slot machine can insert cash

A person playing a slot machine can insert cash, or in Ticket-In, Ticket-Out machines, a paper ticket with a barcode, into a designated slot on the machine. The machine is then activated by means of a lever or button, or on newer machines, by pressing a touchscreen on its face. The game itself may or may not involve skill on the player’s part — or it may create the illusion of involving skill while only being a game of chance.

The object of the game is to win money from the machine. The game usually involves matching symbols, either on mechanical reels that spin and stop to reveal one or several symbols, or on simulated reels shown on a video screen. The symbols are usually brightly colored and easily recognizable, such as images of fruits, numerals or letters, and simple shapes such as bells, diamonds, or hearts; newer video slot machines use animated cartoon characters and images of popular actors or singers (in the case of themed slot machines, as described below).
