How Do Slot Machines Work?

Reading Time: 6 minutes

Slot machines reign supreme in land-based and online casinos. The ongoing bond between video slots and players is founded in the games’ simplicity, fun and colorful themes, and massive winning potential, and reinforced by evolving gameplay concepts and modern features.
While video slots are much newer than traditional casino games such as blackjack, roulette, or poker, they are the players’ favorite. Despite this, many people don’t know how video slots work, what the secret behind their algorithm is, or if there is any way to predict the outcome of the next spin.
Join us as we take a deep dive into the world of video slots and explore their inner workings.

Slot machines may seem complicated at first glance, but understanding how they work isn’t difficult. Despite modern slots’ various gameplay rules and mechanics, most games still follow the same basic design using standard reels, rows, and paylines.
Each video slot contains several reels that, once you hit the Spin button (or pull the lever if you’re playing on an old one-armed bandit), spin around and stop to show a particular combination of symbols.
A limited selection of those symbol combinations can result in a win, usually when several matching symbols appear across what’s called a “payline,” a horizontal, diagonal, or zig-zag line that goes through the reels from left to right. The more matching symbols there are on a payline, the bigger the win. A slot machine can contain between one and several thousand paylines, while some games even allow players to adjust the number of active lines. However, keep in mind that the number of paylines (essentially the number of different ways a player can win) is not indicative of how rewarding that slot machine is.
Also, not all symbols are created equal. Slots typically feature low-paying symbols in the form of card royals (J, Q, K, A), while their high-paying symbols include various pictures and items related to the game’s theme.
Many modern slot machines have bonus games that trigger once a particular combination of symbols appears on the screen. These bonuses can take the form of free spins, pick-em games, multipliers, and more.

How Do Online Slot Machines Work?

Online video slots work pretty much the same way as their land-based counterparts. The rules and gameplay concepts remain identical. Some classic land-based machines have been given online versions over the years, while many developers create slots for both online and land-based play. The only real difference is in accessibility and the number of available games.
Playing slots online is easier, more convenient, and less expensive. You don’t have to physically travel to a casino and pay for gas and accommodation, and the minimum limits on online slots tend to be pretty low. You can switch from one slot to another in just a few clicks or screen taps instead of walking to another machine that may even be occupied.
An average online casino may have thousands of video slots on display. Meanwhile, unless you’re playing in one of the major brick-and-mortar establishments, a land-based casino will only feature a few hundred different slots.

How Do Slot Machine Algorithms Work?

Online Slot Machine | Fortune Coins BlogTo fully understand how casino slot machines operate, you first must understand the meaning behind the abbreviations RNG and RTP.
RNG stands for “random number generator.” It’s a software algorithm that ensures all the outcomes of a video slot game are unbiased and randomly determined. The complexities of RNGs deserve their own detailed article, but to put it simply, once you press the Spin button, the RNG randomly chooses a single combination of symbols to display on the reels. Whether that combination wins or loses depends on the rules of that specific slot.
RNG plays no favorites and does not follow a pattern. Whether you’re at the start of your session or have spun the reels for hours, the chance to hit the jackpot on the very next play is always going to be the same.
Meanwhile, RTP stands for “return to player” and estimates how rewarding a given slot machine is. It is a percentage number inverted to that of the house edge, showing how much a player can expect to receive back from the machine on average.
For example, if the RTP is 96%, that means that for every 100 coins invested in the game, the player will receive 96 coins back over time. However, keep in mind that the RTP figures are based on extensive testing of slots spanning millions of spins and are not indicative of the potential results of your real-life gameplay session.
A game can potentially pay 50% or 200% during your playing time, but this doesn’t mean it’s broken or that it will pay less or more later. No matter how lucky or unlucky you were during your session, the slot machine will always aim for that 96% going forward.

How Do Online Slot Machines Work in Social Casinos?

Aside from land-based and online casinos, there are also social casinos like ours, and our slots work the same way as in any other type of casino.
All Fortune Coins slots function based on a random number generator, and each title has a specified RTP. The games have been tried and tested to ensure fair outcomes for all players. What’s more, our slot selection matches any major casino site, ranging from vintage-looking fruit machines to modern games with loads of bonus features and advanced gameplay mechanics.
The only difference is that we enable you to play online video slots for free. We won’t require you to purchase any coins and will constantly supply you with extra FC and GC through our daily and periodic promotions. If you’re lucky enough to win enough Fortune Coins, you can redeem them for rewards.
Another advantage of social casino slots over standard online casino slots is their availability. Social casinos are available in nearly every U.S. state and Canada, while online casinos are legal in only a handful of states and provinces.

How to Win Playing Slots

Considering that slot outcomes are entirely random, you may wonder how to develop a reliable winning strategy when playing your favorite titles. Well, it’s not possible.. With symbol combinations that show no patterns and return percentages that are consistently below 100%, winning on slot machines is entirely dependent on luck and lots of it.
Nevertheless, there are a few methods you can use to maximize your chances:

  • Play high-RTP slots — The higher the RTP, the higher the return you can expect, at least theoretically. You can still win more coins on a 90% RTP slot than on a 98% if you get lucky, but you’ll be much better off in the long term on the one with the higher rate.
  • Use casino bonuses — Casino bonuses are free credits you can turn into winnings by playing video slots and other games. The best bonuses are those you don’t have to pay to receive, like our Fortune Coins sign-up bonus, which grants you free FC and GC as soon as you register.
  • Limit your play sessions — It’s important to know when to stop, as video slots can be quite addictive. Many players are too eager to chase after losses or get greedy once they’re on a winning run, only to lose it all in minutes. If you can’t stop on your own and feel like you’re losing control, make use of responsible gaming tools like session limits, time-outs, and self-exclusion.
  • Play jackpot slots — Progressive video slots feature massive jackpots that are hard to resist. What’s great about them is that you don’t need to have any experience or do anything specific to become eligible, so you may as well try a few spins and hope the RNG gods smile upon you.

Final Words

We hope that this guide to the mechanisms of video slots helped you better grasp the intricate blend of technology and psychology behind them. Now that you know the outcomes are random, you can relax and play, knowing luck is the only factor determining whether you win or lose.
