Slot Machine is a casino
gambling machine with three or more reels which spin when a button is
pushed. Slots are also known as one-armed bandits because slot machines
were originally operated by a lever on the side of the machine (the one
arm) instead of a button on the front panel, and because of their
ability to leave the gamer penniless. Many modern machines still have a
legacy lever in addition to the button.
Slot Machines include a currency detector that validates the coin or
money inserted to play. The machine pays off based on patterns of
symbols visible on the front of the machine when it stops. Modern
computer technology has resulted in many variations on the slot machine
concept. Slot machines are the most popular gambling method in casinos
and constitute about 70 percent of the average casino's income.
A person playing a slot machine purchases the right to play by inserting
coins, cash, or in newer Ticket-In, Ticket-Out machines, a bar-coded
paper ticket, 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 touch screen 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-based machines
use animated cartoon characters and images of popular actors or singers
In the last few years, new multi-denomination slot machines have been
introduced. With these slot machines, the player can choose the value of
each credit wagered (the stake) from a list of options. Based upon the
player's selection, the slot machine automatically calculates the number
of credits the player receives in exchange for the cash inserted and
displays the amount of available credits to the player.
