• The most popular one, invented by Sittman and Pitt of New York, was a 'poker machine' that was similar to a slot machine and used 5 reels with 10 poker cards on each reel.

• The history of slot machines begins with their invention. The race to produce the first commercial slot machine reached its height in the last decade of the nineteenth century. On opposite coasts of the United States, people were striving to make a handy and fun game that could be played in all sorts of venues, whether it was in a diner or a bar.

Sittman and Pitt of Brooklyn, New York developed a gambling machine in 1891 that was a precursor to the modern slot machine. It contained five drums holding a total of 50 card faces and was based on.

Introduction

The first mechanical slot machine was invented in the late 1800's by a Bavarian imiagrant named Charles Fey (1862-1944) in San Francisco. In order to understand the history of the slot machine though we need to jump back a little in time.

Poker Machines

Before Fey’s invention there were other coin-operated games of chance. The most popular one, invented by Sittman and Pitt of New York, was a 'poker machine' that was similar to a slot machine and used 5 reels with 10 poker cards on each reel. These machines were very profitable and were used in hundreds of locations (mainly in cigar stands) in the 90's (the 1890's that is). The machines paid out prizes, like a free cigar or free drinks, which were distributed manually by an attendant.

Charles Fey

When Charles began building machines, he initially built ones that were similar the popular poker machines and called them by various names, like the 'Duke' and the 'Klondike'. After building a few of them, placing them in locations, and doing very well with them, he then opened a factory in San Francisco to work on his machines full-time.

But Fey wanted to build a machine that would pay out automatically. This wasn't possible at the time due to the difficulty of calculating the vast number of winning combinations of a machine with 5 reels and 10 cards on each reel. So, in 1898, Fey designed a poker machine called the 'Card Bell' machine that retained the card symbols of the earlier poker machines but had only 3 spinning reels and only 5 symbols printed on each reel. The automatic prize-payout allowed the machine to be the first to pay out coins.

The 'Liberty Bell'

About a year later, in 1899, he created the 'Liberty Bell' machine, which added horseshoes and bells to the suit symbols on the reels. Lining up three bells would win the top prize (hence the name). Fey's design became the standard design for slot machines going forward and was so popular that all 3-reel slot machines were referred to as 'Bell Machines'.

Fey rented his machines to saloons and bars and split the profits 50/50. The demand for Liberty Bell slot machines was huge and allowed Fey to monopolize the slot machine market. Many gambling supply manufacturers wanted to buy the manufacturing and distribution rights to the Liberty Bell but Charles Fey didn't want to sell them.

But Fey could not keep up with the demand so in 1907 he partnered with Mills Novelty Company to manufacture a cast-iron machine called the 'Mills Liberty Bell'.

Unfortunately for Fey, patent laws of the time did not protect gaming devices because a Federal Judge ruled the slots could only be used for gambling and had no useful purpose. So a few years later, in 1910, the Mills Novelty Company introduced a slight variation to the Mills Liberty Bell called the 'Operator Bell'. The machines from Mills Novelty were the first to use the fruit symbols like lemons and cherries that you see on some slot machines today.

1910-1933

Part of the growth of slot machines was due the wide open nature of San Francisco during the early 1900's. The climate started to change quickly though in 1909 when San Francisco outlawed all gaming machines. Nevada did the same a year later and the state of California created a statewide ban on slot machines in 1911.

These laws did not have much of an effect on slot machine sales because slot machine manufacturers were able to find ways to alter the games to avoid getting them classified as gambling devices.

For example, the 'Liberty Bell Gum Fruit' model dispensed a package of gum, which allowed the machine to be classified as a vending machine. The Caille Brothers slots created machines that had a Swiss music box located in the bottom of the cabinet so the machine was classified as a musical device. Another popular strategy was to have slot machines dispense items like mints or gum in order to have them classified as vending machines.

Slot machines reached their peak sales during the Great Depression and the lawless days of prohibition, which began in 1919. They were popular in the speakeasies as well as the many respectable businesses that needed the profitable machines in order to stay in business during the tough economic times.

When Was The First Slot Machine Invented

After prohibition ended the government decided to target slot machines since they were looked at as tools for organized crime. Raids began to increase as well as laws prohibiting the possession of slot machines or a sale of a slot machine to an illegal state. Despite these efforts, the popularity of slots machines was difficult to stop and slots were still able to operate in some places.

Post WWII

After World War II, governments started to become friendly to the slot machine industry because it now looked at it as a source of tax revenue.

Computer Technology

In 1963, Bally developed the first electromechanical slot machine, called Money Honey, that used electronic micro-processors to decide the outcome of the game.

When Did Slot Machine Invented

The first fully-electronic slot machines were introduced in Las Vegas in 1975. They were built by the Fortune Coin Company and used simulated reels on a monitor. The electronic machines caught on slower than expected because many players did not trust the fairness of the machines. In 1978, the company that would later be known as International Game Technology bought out the Fortune Coin Company.

In 1984, a Norwegian scientist named Inge Telnaes received a patent for a device titled, 'Electronic Gaming Device Utilizing a Random Number Generator for Selecting the Reel Stop Positions.' International Gaming Technology (IGT) bought the patent in 1988 and now all slot manufacturers his technology must license the patent from IGT.

1990s: The Online Revolution

WMS Industries Inc. had been hovering around the slot machine industry for a few years, but by the 1990s they had grasped the video slot revolution by the horns.

WMS developed its first video slot with a second screen bonus. Reel 'Em In featured a fishing theme where players were able to trigger a Pick'em style bonus game. It paved the way for second screen bonuses like free spins for years to come.

A speedier and cheaper internet allowed online gambling manufacturers to start developing slots that could be played at home. Microgaming had already been operating an online casino since 1994 but launched Cash Splash in 1998, one of the world's first ever online progressive jackpot slots.

As broadband speeds and operating systems improved, the number of developers grew. Major players like NetEnt, Playtech, and Play'n GO all started up operations in the 1990s and continue to innovate and expand. Online games became slicker and became available to play through both download clients and via web browsers.
