A phenomenon that is depopulating a lot on the Web, everyone talks about it and more and more people are passionate about it: they are the slot machines! But how do the brand new machines work online? If you are new to the field and would like to find out before venturing into the world of online slots or if you are already a regular player, but would like to learn more about how slot machines work, here is an informative article. A sort of guide to better understand what lies behind the VLTs and how they were born.

Before arriving at the current slot machines that we find today in many online and non-online casino sites, it is appropriate to make a historical excursus to have a clear background that led to the birth and consequent success of the slots themselves. Liberty Bell is a mechanical game machine designed in 1887 based on the hugely popular game of poker, which has made it possible to play in an entirely automated way for the first time in history. The "Liberty Bell" slot featured three reels and only 6 symbols: diamonds, hearts, spades, a horseshoe, a star and a split Liberty Bell. Liberty Bell's first prizes were fruit-flavored chewing gum; this explains the birth of the first Fruit Machine. Hence also the correlation with the symbols on the reels that represent the fruits, symbols that are still used today in online slot machines.

The prizes were not initially paid out in cash to evade prosecution as gambling was considered outlawed at the time in the United States. To operate the reel, the side lever had to be pushed down and the players got their winnings at depending on the symbols they managed to obtain. Imagine that the highest payment of 50 cents could be obtained with a combination of three Liberty Bells.

Bally also introduced music chips into the microprocessors, thus allowing slot machines to make different sounds in two moments: when the player introduced coins and when the reels turned.IGT, another very famous gambling content producer, invested in the development of new technology slots, purchasing the Fortune Coin patent in 1976 and ensured the success of a machine on the market that already had the potential, giving life to a new generation of games. In 1986 IGT also created and released the first progressive slots, the first ever being Megabucks.
