Gambling has two basic characteristics that contribute to its popularity. One is the entertainment factor and this in turn is combined with the prospect of winning. The two features in combination, are the cornerstones of many gambling games, including slots.

That this concept already over 2,000 years ago has been discovered and at the time the first form of slot machines, which have come mostly known as slot machines, appeared to know the least. In general, the first slot machine is dated to 1896. Because at that time the German mechanic Charles Fey developed a mechanical slot machine with the name "Liberty Bell".

 He developed the very popular device in San Francisco, where he was living at the time. But the truly first slot machine was in ancient Greece in order constructed by priests. Developed by engineers mechanical oracle was called "The will of the gods". As today's slot machines, the device had the task of entertaining the people of Greece and the former uniqueness while also amaze.

In addition, priests could thanks to this first slot machine to their temple fund fill quickly. But unlike today's slot machines, the device was less a game than actually a kind of oracle, which statements about the supposed future of the user said. Similar devices are still to be found to October festivals and other events.

It is clear that even at very early times these machines grew in popularity. Over time, the resourceful people and the technologies available increased. As mentioned already in 1886 a further more advanced device was developed by Charles Fey. Three years later, the brothers developed a Caille slot machines with the name "Black Cat". But the three-reel-equipped device from Fey has enjoyed great popularity and was copied around the world several times. The development in this direction was the basis for today's slot machine industry.

In 1907, Herbert Mills developed a new device called "Operator Bell", which briefly made it to the masses and was sold. These devices were mainly situated in small bars and gambling halls. The "one-armed bandits" - as the forerunner of Fey was also called - are found in the lavish casinos of Las Vegas. In the following years many different models have been developed, which, however, brought no major changes. These include the automatic "Rotamint" from 1952.

Another milestone in the development of slot machines was the year 1963, in which the company developed "Bally Technologies, a new device called" Money Honey ". The special thing about this was that it was completely electro-mechanically operated. In the following years have been increasingly developed progressive slot machines. Meanwhile, there are already models that feature a touch screen and be completely controlled by them.
