In 1891, a gambling machine has been developed by Pitt and Sittman of Brooklyn, New York, U.S.A., which can be regarded as the precursor of the modern styled slot machine. The machine was depending on the game of poker containing 5 drums that holds a total of 50 face cards. The machine got vast popularity and very soon it established a place at the side of many bars in the city. Players would be inserting a coin or nickel and then pulling the lever, through which the drums get spun and the cards are held towards them, the player hopes for the good hand of poker. No direct mechanism of paying outs exist there; therefore a player might be getting a beer with a pair of kings, whereas he could get drinks or cigars with a royal flush. The offer at the confined establishments was the basis of the prizes given to the players. Typically, 2 cards were detached from the deck for making the better odds for the casino house: the Jh and the 10s, through which the winning odds of a royal flush are cut by the half. There could also be the re-arrangement of the drums regarding the reduction in the winning chances of a player.
In 1887, Charles Fey of San Francisco, California, U.S.A, has invented the 1st one-armed bandit, who was the one through which a very simple automatic mechanism ha been devised. It had really proved impossible for coming up with a way for making a machine competent to make an automatic payout for all the possible combinations of winnings because of the huge number of possible wins with the original game based on the poker cards. The machine with the 3 reels, devised by Charles Fey that contains total 5 symbols i.e. the diamonds, the horseshoes, the spades, the hearts and a Liberty Bell, with which the machine got its name. By the replacement of 10 cards with 5 symbols and the use of 3 reels in place of 5 drums, there reduced considerably, the complications in the reading a win, allowing Fey, devising an effective mechanism for automatic payouts. Ten nickels, which are the biggest payoff, is produced in a row of three bells. Liberty Bell got a massive success and produced a prosperous industry of mechanical gaming device. Even when it was ban to use these de4vices of gambling in his domicile state after some years, Fey still could not continued with the demand for slot machine game any where else.
