Sittman and Pitt of Brooklyn, NY, developed a gambling machine in 1891, that was a precursor to the present day slot machine game. It contained five drums holding a complete of 50 card faces predicated on poker. This machine proved popular and quickly many bars in the town had a number of these. Players would insert a nickel and pull a lever, which would spin the drums and the cards they held, the player longing for an excellent poker hand. There is no direct payout mechanism, so a couple of kings could easily get the player a free of charge beer, whereas a royal flush could spend cigars or drinks, the prizes wholly reliant on what was available at the neighborhood establishment. To help make the odds better for the home, two cards had been typically taken off the deck: the ten of spades and the jack of hearts, which doubles the chances against winning a royal flush. The drums may be rearranged to help expand reduce a player’s potential for winning.

Due to the multitude of possible wins with the initial poker card game, it proved practically impossible to create a method to make a machine with the capacity of making a computerized payout for all possible winning mixtures. Somewhere within 1887 and 1895, Charles Fey of SAN FRANCISCO BAY AREA, California, devised an easier automatic mechanism with three spinning reels containing a complete of five symbols: horseshoes, diamonds, spades, hearts, and a Liberty Bell. The bell gave the device its name. By replacing ten cards with five symbols and using three reels rather than five drums, the complexity of reading a win was considerably reduced, allowing Fey to devise a highly effective automatic payout mechanism. Three bells in a row produced the largest payoff, ten nickels (50¢). Liberty Bell was an enormous achievement and spawned a thriving mechanical gaming device industry. Even though, over time, the usage of these gambling devices was banned in his home state, Fey still cannot match demand for them somewhere else. The Liberty Bell machine was so popular that it had been copied by many slot machine game manufacturers. The to begin these was a machine, also known as the “Liberty Bell”, made by the maker Herbert Mills in 1907. By 1908 plenty of “bell” machines had been installed generally in most cigar stores, saloons, bowling alleys, brothels and barber shops. Early machines, including an 1899 “Liberty Bell”, are actually section of the Nevada State Museum’s Fey Collection.
The first Liberty Bell machines made by Mills used the same symbols on the reels as Charles Fey’s original. Soon afterwards, another version was produced with patriotic symbols like a flag and a wreath on the wheels. Later, an identical machine, rechristened the Operator’s Bell, was designed, that an optional gum vending attachment was available. As the gum offered was fruit-flavored, fruit symbols were positioned on the reels: lemons, cherries, oranges, and plums. A bell was retained, and an image of a stick of Bell-Fruit Gum, the foundation of the bar symbol, was also present. This group of symbols proved very popular, so was utilized by the others that started to make their own slots: Caille, Watling, Jennings and Pace.
In 1963, Bally developed the 1st fully electromechanical slot machine game, called Money Honey (although earlier machines like the High Hand draw poker machine by Bally had exhibited the fundamentals of electromechanical construction as soon as 1940). The electromechanical strategy of the 1960s allowed Money Honey to be the initial slot machine game with a bottomless hopper and automatic payout as high as 500 coins without assistance from an attendant. The popularity of the machine resulted in the increasing predominance of electronic games, with the medial side lever soon getting vestigial.
The first video slot machine game originated in 1976 in Kearny Mesa, California, by the Las Vegas-based Fortune Coin Co. This slot machine game used an altered 19-inch (48 cm) Sony Trinitron color receiver for the display and logic boards for all slot machine game functions. The prototype was mounted in a full-size show-ready slot machine game cabinet. The first production units continued trial in the NEVADA Hilton Hotel. After some “cheat-proofing” modifications, the video slot machine game was approved by the Nevada State Gaming Commission and finally found popularity in the NEVADA Strip and downtown casinos. Fortune Coin Co. and their video slot machine game technology were purchased by IGT (International Gaming Technology) in 1978.
The first American video slot machine game to provide a “second screen” bonus round was Reel ’Em In produced by WMS Industries in 1996. This kind of machine had appeared in Australia from at least 1994 with the “Three Bags Full” game. In this sort of machine, the display adjustments to supply a different game where yet another payout could be won or accumulated.
