gazed at a modern slot machine as if it were a piece of alien aircraft, then you couldn&#8217;t have stumbled upon a better article. Consider this your handy toolkit to not just play slot machines, but to truly understand how they work.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"WHEN_WAS_THE_SLOT_MACHINE_INVENTED\"><\/span>WHEN WAS THE SLOT MACHINE INVENTED?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The first slot machine game was invented by Charles Fey in San Francisco back in 1894. It was the first variation of what we now call &#8216;fruit machines&#8217; or &#8216;one-armed bandits&#8217;.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although somewhat similar to modern slot machines, the Liberty Bell \u2014 as Charles Fey named it \u2014 only featured card suits, bells and horseshoes. Moreover, Liberty Bell only had three reels and one payline, but the entertainment it brought was previously foreign to the whole world.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As might be expected, Liberty Bell \u2014 then simply labelled a &#8216;gambling machine&#8217; \u2014 had very rudimentary mechanics.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Players would deposit nickels in the coin slot and then turn the lever to get the physical reels rolling.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The lucky players who landed winning symbols would be greeted by the sound of a bell and a grand prize of fifty cents in a small metal shaft.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"TYPES_OF_SLOT_MACHINES\"><\/span>TYPES OF SLOT MACHINES<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Liberty Bell was the foundation of all slot machines. Once technology and innovation picked up pace, the sky was truly the limit when it came to creating brand-new slots.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here are the most common types of slots in the contemporary world of gaming.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"CLASSIC_SLOTS\"><\/span>CLASSIC SLOTS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For a long time, classic casino slot machines were the talk of the town. Slot enthusiasts would flock to their nearby land-based casino to spend time spinning reels in the hopes of bagging a bonanza, while casino managers saunter around the place to supervise and assist when necessary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Classic slots are reminiscent of Liberty Bell, only that they are played on modern machines in equally modern casinos.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The physical reel made way for the virtual reel layout, visible on an in-built display. Most classic slots feature three reels and fruity symbols.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"FIVE-REEL_SLOTS\"><\/span>FIVE-REEL SLOTS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The innovation of five-reel slots allows for various features or bonus games to be implemented within the game, some of which might offer multipliers and even free spins.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In most five-reel video slots, a bonus game could be unlocked by landing a certain number of Scatter symbols, but this differs between slot games.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"JACKPOT_SLOTS\"><\/span>JACKPOT SLOTS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Jackpot slots usually take the form of five-reel slots, only that you could win a large sum of money with any random spin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This could be done either by landing certain jackpot symbols, or simply through sheer luck.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The maximum jackpot amount is usually predetermined by the provider, but it is known to be in the thousands and, in some cases, millions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Progressive jackpots work the same way, only that each spin contributes to the size of a jackpot.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"WHAT_IS_THE_DIFFERENCE_BETWEEN_ONLINE_SLOTS_AND_REAL_ONES\"><\/span>WHAT IS THE DIFFERENCE BETWEEN ONLINE SLOTS AND REAL ONES?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Although both online slot machines and mechanical slot machines work through digital technology, there are some key differences between the two.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Firstly, online casinos offer hundreds of slots \u2014 and in EnergyCasino&#8217;s case, thousands! These are all accessible through a single click, whereas physical slots aren&#8217;t as easy to browse through.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Physical casinos tend to pack multiple machines within a confined area, so if someone else is hogging a particular slot machine, you&#8217;ve got no choice but to wait.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Secondly, online slot machines are completely virtual. This means that there won&#8217;t be any need for dropping coins into a box and pulling a lever, since clicking the spin button will suffice.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"HOW_DOES_A_SLOT_MACHINE_WORK\"><\/span>HOW DOES A SLOT MACHINE WORK?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If certain symbols fall on a winning line, the slot machine pays depending on two factors: the bet amount placed and the value of the particular symbols on the pay table.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The minimum bet \u2014 just like any other very small bet \u2014 won&#8217;t net a player a big sum, as will be the case if a player lands low-value symbols on a payline.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Also, factors like Return to Player (RTP) and game volatility have a big say in the win frequency.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The RTP refers to the average payback percentage that the slot is expected to deliver over time, like a reverse house advantage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The volatility \u2014 ranging from low to high \u2014 refers to the size and hit frequency of a winning combination.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"DIFFERENCES_BETWEEN_MODERN_AND_PAST_SLOT_MACHINES\"><\/span>DIFFERENCES BETWEEN MODERN AND PAST SLOT MACHINES<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Placing Liberty Bell and any modern slot game side by side will be enough to outline some of the big changes to slots that have happened over the years.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Early machines were extremely basic \u2014 offering a select few symbols and no bonus game to keep things interesting.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In fact, it&#8217;s very likely that contemporary gamers would grow bored of an old slot game within minutes of pulling the spin lever.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The bar is understandably much higher with regards to newer slot machines. Nowadays, bonus features, high-definition graphics and polished animations are staples of casino games, and any of them that don&#8217;t include those elements stick out like a sore thumb.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"WHICH_CONDITIONS_SHOULD_BE_FULFILLED_BY_THE_PROVIDER\"><\/span>WHICH CONDITIONS SHOULD BE FULFILLED BY THE PROVIDER?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Before releasing a game, slot providers work around the clock to make sure that their product is up to the industry&#8217;s standard.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This means that, prior to release, the product must tick the right boxes in terms of compliance and fairness.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Apart from that, QA professionals take care of rigorously testing the game before it is launched into the world of gaming. At this point, the game developers take a back seat and respond to the reports issued by the QA engineers.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"WHAT_IS_THE_SYSTEM_BEHIND_SLOT_MACHINES\"><\/span>WHAT IS THE SYSTEM BEHIND SLOT MACHINES?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Physical slots \u2014 also referred to as coin slots \u2014 used to work like a vending machine in their early stages.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In old slots, a braking system brings the reels to a stop if a win combination is landed. In modern slots, players can make the reels stop prematurely, but this doesn&#8217;t affect their odds of winning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Both physical and online slot machines nowadays use a computer program to make the reels spin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, they use a Random Number Generator to randomise a player&#8217;s odds of winning, as we&#8217;ll explain later on.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"WHICH_SLOT_MACHINES_ARE_SAFE\"><\/span>WHICH SLOT MACHINES ARE SAFE?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Nowadays, many reputable licensing companies provide certifications for legitimate slots, as long as they are, indeed, entirely lawful.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The good news is that you don&#8217;t need to travel to the glamour-saturated Las Vegas to play legitimate slots.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Such games are completely accessible at EnergyCasino through a simple web search! We&#8217;ve got thousands of slots in our game portfolio, featuring many different themes and categories for you to choose from.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you want to take a break from slots, feel free to check out our other games, including table games and Live Casino games.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our Casino is licensed by the Malta Gaming Authority \u2014 some of the most reputable gaming authorities in the world.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"HOW_IS_A_SLOT_MACHINE_PROGRAMMED\"><\/span>HOW IS A SLOT MACHINE PROGRAMMED?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The common denominator of all modern gambling machines is the Random Number Generator.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Legitimate slot machines use Random Number Generators to continuously cycle through millions of numbers, making the outcome of each spin completely unpredictable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although some slots include bonus features, this doesn&#8217;t take from the fact that all legitimate slot machines have a random chance of delivering wins.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"HOW_TO_CHECK_THAT_SLOT_MACHINES_ARENT_RIGGED\"><\/span>HOW TO CHECK THAT SLOT MACHINES AREN&#8217;T RIGGED<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Most casinos that have obtained reputable licences are quite a safe bet to make when it comes to taking any of their slots for a spin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Having said that, all slots feature an in-built house advantage, which means that although you could win money in small bursts, losing money will probably happen too.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This doesn&#8217;t mean that most machines are rigged \u2014 that is simply the nature of slots.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"HOW_TO_DETERMINE_THE_FREQUENCY_OF_WINNINGS_AND_THE_AMOUNT_OF_WINNINGS\"><\/span>HOW TO DETERMINE THE FREQUENCY OF WINNINGS AND THE AMOUNT OF WINNINGS?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The frequency of wins in a slot machine is roughly calculated by its volatility.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A low-volatility slot will deliver smaller wins frequently, whereas highly volatile slots pay more but not all too often. Medium-volatility slots fall somewhere in between.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you&#8217;ve ever gazed at a modern slot machine as if it were a piece of alien aircraft, then you couldn&#8217;t have stumbled upon a better article.
