The history of the first slot machine dates back to 1895. The father of the first slot machine was Charles Fey, whose original slot machine had poker symbols on its three spinning reels. The symbols also included hearts, horseshoe, bells and spades. Since the game only had 3 reels, it was easy to make the game pay out for the winning combinations automatically. The paytable of the game was available at the top and it showed players the different winning combinations. The highest combination paid 50 cents when players got 3 bells on the win line.
In 1891, another form of slot machines was invented by Sittman and Pitt. This new machine looked a lot like the early version of slots that can still be found to this day. The game included five drums and 50 cards with a poker game theme since players were paid according to the poker hand they formed. This is why they were called poker machines. Players would start the game by putting a nickel into the games slot and pull the lever in order for the drums to spin so they could get a poker hand. Most of these machines used to pay players in the form of gifts such as cigars, drinks or food or other things that were sold at the pub or the bar where it was being offered. In order to increase the odds of the house and make it hard to get a poker hand of a Royal Flush, the game did not have a 10 of Spades or a Jack of Hearts.
In 1907, Herbert Mills invented another machine that was called Operator Bell and by 1908 these slots were installed in every bowling alley, cigar store or salon. One of these original Liberty Bell slots can still be found in a Reno Restaurant in Liberty Bells Saloon.
Another great development occurred in 1963 when Bally invented the 1st electromechanical slot machine called The Money Honey. This was the first slot to have a bottomless hopper and it offered automatic payouts as well. The biggest reward that could be claimed was 500 coins. This machine was one of the reasons behind the skyrocketing rise of electronic gambling. Reel Em was the first ever video slot that offered players any kind of bonus rounds.
Multi line slots made an entrance to the scene in 1990s. These games had more than one winning line. This means that players could claim payouts according to combinations on more than one line that are aligned on the games screen. With the emergence of online gambling, slots were one of the first games to be adopted and transformed into online games. They developed quickly and can now offer up to 100 lines and 1024 ways to win. They also offer players a lot of bonuses in the form of wilds, scatters and rewarding jackpots.
