A Brief History of Slot Machines:
Slot machines have been around and attracted people for over a century now. Charles Fey, the inventor, created the first slot machine in 1895, called “Liberty Bell”. Some others believe that he invented it in 1887.
In 1963, Bally developed the first fully electro-mechanical slot machine called “Money Honey”. The first American video slot machine to offer a "second screen" bonus round was “Reel 'Em In” developed by WMS Industries Inc. in 1996. This type of machine had appeared in Australia from at least 1994 with the "Three Bags Full" game.
How The Original Slots Worked:
Inside each slot machine there were three metal hoops called reels. Each reel had ten symbols painted on. For each time the lever was pulled, the reels spun once. Then, a prize was awarded if three of a one kind of symbol lined up. The payoff in coins was then released from the machine.
In Slovakia and across the European Union, video slot machine is a more recent innovation than the classic slots. It has no moving parts at all, no metal hoops/reels instead a graphical representation of reels, appear on a screen. And since the player is basically playing a computer game, the manufacturers are able to offer more interactive elements, such as advanced bonus games and advanced graphics.
In addition, most video slots display five reels rather than three and that’s because there are no constrains on the design, unlike slots. This greatly expands the number of possibilities: a machine can have 50 or more symbols on a reel, giving odds as high as 300 million to 1 against – enough for even the largest jackpot.
Video slots frequently encourage the player to play multiple lines, so rather than simply taking the middle of the three symbols displayed on each reel, a line could go from top left to bottom middle to top right. The pattern of the lines is defined by the manufacturer, and differs from each video slot.
All modern machines are designed using pseudo-random number generators ("PRNGs"), which are constantly generating random numbers, at a rate of thousands or more per second. As soon as the "Play" or “Spin” button is pressed, the result is decided by the latest random number. This means that the result varies depending on exactly when the game is played. If the Play/Spin button were pressed by a fraction of a second earlier or later; the result would be different.
Slot machines are commonly programmed 82% to 98% of the money that is wagered by players, to pay out as winnings. This is known as the "theoretical payout percentage" or RTP, "return to player". The minimum theoretical payout percentage shapes depending on the jurisdictions and is typically established by law or regulation.
The winning patterns on video slots, the amounts they pay and the frequencies of payouts are carefully selected to yield a certain fraction of the money played to the “house”. The rest returns to the players during play.
Bonus is a special feature, unique on each game, which is activated in a certain combination, assigned by the manufacturer. Bonuses differ depending on the game. Usually bonuses give out free spins and often winnings in bonus round are increased by a specific multiplier. Some other bonus rounds, player is given several items on a screen from which to choose. Number of credits is revealed as the player clicks and chooses items. And then, some other bonuses use a mechanical device, such as a spinning wheel, that works in combination with the bonus to display the amount won.
Reels: All slot machines used revolving mechanical reels to display and determine results. Three reels is the standard, when 5 reels are most commonly.
