Slots are a very innovative and theme enriched game, which makes it hard to wonder that it is basically an invention as old as a century. Developed for the first time in 1887, by a mechanic in a town of the American state of California, slots humbly began with three reels and five symbols. These symbols were spades, hearts, diamonds, horseshoes and Liberty Bell. The slot machine developed by Fey came to be known as the Liberty Bell and gained popularity across entire America. The level of fame was such that when gambling was banned in California, Fey was still unable to fulfill the ever increasing demand for the machine from other states.
The three reels in the original machine were modified by Sittman and Pitt from New York in 1891. They modified the machine into a five reeled, 50 card slot machine and the payouts resulted because of numerous poker combinations.
The next innovation in the slot machines came in 1963 when Money Honey came to the picture. It was developed by Bally manufacturers and was the first completely electromechanical slot machine which could give payouts of around 500 coins without human help.
Video slots came as an exciting innovation to the game in 1976, and they became much more famous when some cheat proof modifications were done to them. They got much popularity in the Vegas casinos and to this day are a favorite there.
Technological advancement has lead to increasing the active play lines on a slot from almost 9 to 50. In some more modern machines, there are no play lines at all; rather more than 243 ways of increasing chances of winning have been introduced.
As slots are immensely famous in casinos and people love playing them, they make up the major portion of the games that are available in a casino. Moreover, the profit they generate also makes them a favorite for the owners. The introduction of online casino games has let the physical attributes of slots vanish and hundreds of slots are now available online with different themes, many different features and variety of coin sizes.
Another modification that the slot industry has seen is the introduction of movie based slots which increases the demand of more interesting, lucrative and graphically appealing games. This has also upped competition among the developers of the game.
