Sittman and Pitt in Brooklyn, New York, USA, developed the first type of a slot machine in 1891, which was the precursor to the modern slot machine. This slot contained five drums which had a total of fifty photographs which were based on poker. This slot machine proved to be very attractive, and soon many bars in Brooklyn had one or more of these slots. Players would insert a coin, a nickel and pull a lever.
This move resulted in the cylinders spun and stopped showing 5 symbols representing a poker hand. The better the hand, the better payout. At the beginning of these slots, there was no payout mechanism though. This meant that the player had to show the bar owner what hand he got at the slot machine, such as a set of queens. This could in turn lead to a pair of glasses or a bottle in the bar. The better the hand, the better the bar order simply.
Because of the large number of potential winning hands in a standard poker game, it was practically impossible to come up with a way to produce a slot machine that could make an automatic payment for all possible winning combinations. For this reason, Charles Fey a few years later invented a slot machine that had three spinning reels with five symbols; Horseshoes, diamonds, spades, hearts, and a Liberty Bell, which also gave the machine its name.
By replacing ten cards with five symbols and three wheels instead of five, the complexity in finding payment for each win became much less difficult. This in itself resulted in Fey being able to design an automated payment mechanism that was functioning.
Three bells, the Liberty Bell’s, in a row resulted in the largest win. Liberty Bell was a huge success and is the one slot machine that has given rise to the extremely large market available today, not least at the internet casinos. Slots were banned in the US a few years later, but Fey still managed to earn good money on his machine when he began exporting them to other countries. Liberty Bell slot machine became so popular that it later was copied by many manufacturers of slots. For example by game developers of slots for internet casinos.
Herbert Mills from Chicago, manufactured in 1907 a slot machine that came to be called the Operator Bell. The following year, 1908, a large number of his slot machines were placed in most cigar stores, saloons, bowling alleys, and brothels. The original Liberty Bell slot machine can still be seen on Nevada State Museum in Carson City, Nevada.
In 1963 the first fully electromechanical slot machine was developed by Bally and was called Money Honey. The popularity of this machine led to the increasing dominance of electronic slot games, and the side lever soon became no longer necessary and was replaced by a simple button for the player to press. However, the lever is still there on many slot machines, but then most as a ‘fun’ supplement to the button. Even on the internet slots, the graphics contain a side lever in order to contribute to the feeling of the original machines.
The first real video slot machine was developed in 1976 by N. Cerracchio, R. Greene, W. Beckman, J. Reukes, and L. Black together with the Las Vegas-based company Fortune Coin Co. This slot machine used a modified 19″ Sony Trinitron color receiver for display. The first units produced were tested at the Las Vegas Hilton Hotel. After a few modifications, it was an approved gaming machine of the Nevada State Gaming Commission and became after a while popular throughout the strip in Las Vegas. Fortune Coin Co. and its video slot machine technology were later acquired by IGT (International Gaming Technology).
The first US gaming machine offering a “second screen” bonus round was Reel ‘Em In, developed by WMS Industries Inc. in 1996. This type of machine had actually turned up in Australia already in 1994 and was called “Three Bags Full”. In this type of machine, the display changes at a certain combination of symbols and takes you to the “other” game, a bonus game, where bigger wins can be made, which will accumulate to your credit.
A person playing a physical slot can insert cash or, in the Ticket In – Ticket-Out machines, a paper ticket with a barcode. The slot machine is then activated by means of a lever or a button.
The objective of slots is to win money from the gaming machines. The game usually involves matching symbols that spin and stop, and thus results in one or more symbols is in a winning line. The symbols are usually brightly colored and easily recognizable, such as images of fruits, numbers, or letters. In newer forms, mainly on internet casinos, there are simple shapes such as bells, diamonds, or hearts. Newer video slots and internet slots use animated cartoon characters, images, and films by, for example, popular actors and singers.
Most games have a variety of winning combinations of symbols. On physical machines, these combinations are usually shown in a picture on the front of the machine. On the internet casino slots the winning combinations can be seen by pressing a button on the screen, often called paytable or paytable. If a player matches a combination according to the rules of the game, the slot machine will credit the player account or give out some other sort of value, such as extra games, free spins, or the opportunity to reach the gaming machine jackpot.
There are many different types of slot machines in places like Las Vegas. Some of the most popular are the video poker machines where players hope to obtain a set of symbols corresponding to a winning poker hand. Depending on the machine, the player can play a number of different hands at once. Another popular type of gambling machines internationally is the ones for bingo. Depending on the slot machine, a player may play one or more bingo cards simultaneously.
Internet slots with multi-line have become more popular since the 1990s. These machines have more than one payline, meaning that even symbols that are not located in the horizontal line can still result in a winning combination. Physical slot machines usually have three or five paylines, while slots on online casinos can have 9, 15, 25, or even more different paylines. Most internet slots have a specific theme for each game, some with graphics and music based on the theme. Most slot machines accept variable amounts of credit to play. One to fifteen credits per line are common. The higher the amount of your bet is, the higher the payout if you win.
Major casinos and internet casinos offer slot machines with denominations from five cents or pennies all the way up to at least $ 100 or equivalent in British denomination per credit.
On the internet casinos, there are slot machines with a multi-denomination system introduced. On these internet slots, players can choose the value of each credit bet from a list of options. Based on the player’s choice, the slot machine automatically calculates the number of points the player receives in profits and how many credits the player has left.
Some slot games on the internet offer a bonus that is activated when certain symbols appear in a certain order or combination. The bonus varies depending on the game. Some bonus rounds consist of free spins, which amount usually is based on the winning combination that triggers the bonus. These rounds often have a modified set of winning combinations compared to the main game.
These rounds also often mean an increase in credit value by a specific multiplier. The bonus rounds are often easy to recognize by a different color or different graphics than the main game. Another kind of bonus round is when the player is presented with a number of points on a screen to choose from. When the player selects a specific object that contains a win it is awarded to the player’s balance.
The credit meter on the internet casino shows how much money or credit available to the player on the machine.
