What is an Online Slot Machine?

Charles Fey of San Francisco created the Liberty Bell, the world’s first slot machine, in 1894. There was only one payline and three spinning reels on the Liberty Bell. The slot machine had five different symbols: a Liberty Bell, diamonds, spades, hearts, and horseshoes. The slot machine would pay out if three matching symbols showed up on the reels. It is the original slot machine concept and the model that has been utilised to make hundreds of thousands of additional slots over the years.

Types of Online Slot Machines

Slots have evolved from being physical machines to being played online in the modern era. In actuality, the popularity of online slots has surpassed that of physical slot machines. These days, there are many different variations of the most popular online casino game. Online slot machines fall into four primary categories, all of which are easily distinguished from one another. Among the slot kinds are:

  • Classic Slots – The Liberty Bell exemplifies a traditional slot machine. Slot machines with a traditional design normally have three reels and a maximum of nine paylines, frequently five. Additionally, they don’t always offer bonuses—in some cases, none at all.
  • Video Slots – These slots feature five reels or more and any number of paylines, from ten to more than one hundred. Video slots typically have a wild symbol, a scatter symbol, or both (we shall go into more depth about these later). They also usually have at least one additional feature.
  • Arcade Slots – These slots typically include multiple bonus features and special symbols, just like video slots. Arcade slots do not have paylines, though. Instead, clusters, or groups, of symbols adjacent to one another either vertically or horizontally, produce winning combinations. Another kind of arcade slot is one in which wins are generated only by placing a minimal amount of symbols (without having to be adjacent) anywhere on the reels. Cascades, or the tumble feature, are among the most typical features of arcade slots (we shall explain this later on as well).
  • Progressive Slots – These slots are also quite well-liked. Progressives can be found in arcade, video, or classic slots. Slot machines that are progressive differ in that they are connected to a jackpot. The jackpot increases steadily because it is progressive, and it will eventually be won.

Online Slot Machine Guide: How They Work

Slot machines are type of gaming devices that consist of horizontal lines called rows and vertical columns called reels. Three reels, three rows, and five paylines are features of a typical slot machine. The number of winning patterns that can emerge on the reels is referred to as a payline. There are a set amount of symbols in each slot machine, ranging from the least to the most lucrative. Matching symbols on neighbouring reels that form a particular pattern—referred to as a payline—forms winning patterns. Before proceeding with slots, you must understand some basic concepts. These factors include:

  • RNG
  • RTP
  • Volatility
  • Betting Options
  • Winning Combinations

A Random Number Generator determines the result of each round in online slot machines (RNG). Before you press the “Spin” button, a RNG makes sure that every spin is entirely random and that there are no dishonest predetermined outcomes.


Certain characteristics of an online slot machine can aid you in identifying its behaviour. Often referred to as Return to Player (RTP), this percentage represents a slot machine’s house advantage. The house advantage on a slot machine with a 96% RTP is 4%. This implies that you will need $1 for each spin if you play 100 spins with $100. After $100 in spins on a slot machine with a 96% RTP, you would typically get $96 back. Although this is only an average computation based on thousands of spins, it’s a useful tool for comparing slots to one another.


Volatility, another name for variance, is another excellent resource for slot machine information. The volatility of online slots can range from very low to very high. High volatility games have a higher potential of large winners, but they happen much less frequently than low volatility slots, which typically provide minor wins more regularly. Since they pay out more than low volatility slots but are more harder to win, high volatility slots are the most played type of online slots.


It’s critical to have a basic understanding of your betting options before you begin spinning the wheels of an online slot machine. While some slots let you select how many paylines to activate, the majority of slots have a set amount of paylines. You can select the amount you want to bet on each payline when playing fixed payline slots. As a result, if you wager $0.01 on each of the 20 fixed paylines in a slot machine, your total stake for each spin will be $0.20.

In certain other situations, you might have to decide how many coins you want to bet per payline after setting the size of a coin. For example, if you want to bet two coins on a slot machine with 25 paylines and select a $1 coin size, your total stake will be $50. Because of this, it’s essential to know how to change your stake amount before you even play.

Winning Combinations

Slot machine payout structures are generally quite straightforward. For instance, a successful combination in a 5-reel slot machine often consists of just three matching symbols across a payline. In this case, the payout for scoring a winning combination with three matching symbols on a payline may be x1. Even though it is significantly more difficult to produce, a combination with five matching symbols will pay more because there are more symbols in it. The general rule of thumb is that the larger the payoff, the more matching symbols you have across a payline.

Examining the pay table for that particular slot machine is the easiest approach to find out how much each symbol pays. You can determine which symbols are more lucrative than others and how much they pay by looking through the pay table. Certain pay tables feature a multiplier (a figure like x5), whereas other pay tables adjust based on the stake amount.

How to Choose an Online Slot Machine?

Selecting which games to play is a crucial step in the online slots gaming process. To those who are unfamiliar with playing slots online, this could appear like a daunting undertaking. To help you find your perfect game, we have a few suggestions to make things a bit easier. You could also check out our latest jackpot ratings for alternative games to play.

Theme and Design

Slot machines have a wide variety of themes, from leprechauns in Emerald Isle to the historical Egypt. There exist slots that are branded and inspired by popular culture, like the Jurassic Park theme or the Ted movie from 2012.

There’s much more to think about than just the aesthetics, even though a theme gives a space some colour and individuality. A wide range of bonus bonuses and other elements that impact gameplay are typically found in online slots. As previously stated, players will find slots with a higher RTP to be more advantageous, but a slot machine’s behaviour will be determined by its volatility.

Slot Tips

When choosing an online slot, we would generally advise you to do the following:

  • Avoid slots with RTP lower than 96%
  • Play low volatility slots if you are a new player
  • Enjoy bigger wins on high volatility slots (with a bigger bankroll as well)
  • Play slots with themes that you enjoy
  • Look for slots that offer plenty of bonuses

Online Slot Machine Guide: Picking a Top Slot

Even if the themes and features of slots can differ, examining the company that makes the game is another reliable method to ensure that you’re playing a decent game. The majority of slot machines are created by software companies employing a talented group of specialists who know how to design the most played games. Among the most reputable software suppliers on the market are:

  • Microgaming
  • Play’n GO
  • Pragmatic Play
  • NetEnt
  • Playtech

When it comes to software suppliers and casinos, you should only play at establishments that are duly overseen by reputable regulatory bodies. The United Kingdom Gambling Commission, the Malta Gaming Authority, and the Curaçao eGaming control are the most well-known regulatory authorities in the iGaming sector.

Online Slot Machine Guide: Bonus Features

Playing online slots has very simple basic rules. An online slot machine’s grid is made up of rows and reels. The successful patterns on the reels are referred to as the paylines. Winning patterns on the majority of simple slots must begin on the first reel, which is the farthest left on the screen, and proceed from left to right (along a payline). This would mean that the first, second, and third reels would all have a symbol.

But there are also slots that pay in additional ways in addition to paying both ways (from right to left beginning with the fifth reel). We already discussed arcade slots with the cluster payouts feature, which awards points for just having adjacent symbols anywhere on the screen, either vertically or horizontally.

Slot machines may have other typical features in addition to the fundamentals, including bonuses or special symbols. The most well-liked typical attributes are:


These are the symbols that can be used to assist construct winning combinations by replacing any regular symbol.


These symbols, as their name implies, can appear anywhere on the reels and can either pay out or activate a bonus; they are not required to fall across a payline.

Free Spins

The most typical bonus features are these. You may play these free slot machine spins, as the name would imply. Free spins are given out in a lot of slots machines when at least three scatter symbols appear on the reels at the same time.

For instance, getting three scatters could result in ten bonus spins, four scatters in twenty, and five scatters in fifty.


As the name suggests, payout multipliers increase payments. They could show up linked to a bonus round or a symbol. Any victory that includes a symbol would have its multiplier increased by two if the symbol had an x2 multiplier linked to it. The total win of the bonus round is multiplied by three if an x3 multiplier is used.

Bonus Rounds

Numerous different mini-games could appear in an online slot machine, even though the bonus round that consists of the free spins is regarded as such. A picking game where prizes are hidden behind covered symbols is one example of this. By clicking on the symbols, you reveal the prizes behind.


Cascades or the tumble feature, one of the most popular bonuses in arcade slots, are activated by striking a winning combination. When a combination of successful symbols disappears from the reels, other symbols may fall down and maybe create new winning patterns.

Online Slot Machine Guide: Strategies

Online slots are chance-based casino games with a large potential payout. There is a widespread misconception that there is a surefire method to guarantee you make money when playing slots. But since slots are all luck-based, there’s no hard-and-fast rule to winning at them. Since these games use a random number generator (RNG), each and every spin has an equal chance of paying nothing and reaping huge rewards.

Although winning at slots is never certain, there are some tactics you may employ to improve your chances. Making sure you select the appropriate slot machine to play is one of the most effective methods to achieve this. Beyond selecting a game, though, employing a solid bankroll strategy is the best way to improve your odds.

Boost Your Chances of Winning

As was already discussed, lowering your possible losses is the best method to improve your odds. Try using the following tactics to stay within your budget and play as strategically as you can:

Stay with basic slots

If you’re new to slots and want to improve your odds of winning, we advise sticking with basic slots. They might not have as many features, but they are simpler to understand, which could make it easier for you to stay organised. More complex slots are more satisfying to play when you get proficient at it, but up until then, they’re just too complicated, adding more choices and steps to the reel-spinning process.

Play slots with a high RTP and low volatility

It’s important to play slots with a high RTP percentage, especially for inexperienced players. These games are determined to have a smaller house advantage than other games after tens of thousands of spins. Furthermore, low volatility slots pay out more often yet not as generously. When you first start playing online slots, it’s best to stick to low volatility games. However, as you gain experience, you can go on to greater volatility games, which call for a larger bankroll and a lot more patience because there are a lot of lose spins.

Manage your bankroll

When you first start playing slots, controlling your bankroll is the most crucial thing to think about. It’s a good idea to split your bankroll between the amount you want to play with and the amount you want to bet per spin if you decide to play with a specific amount. You could play for however long you wanted to without going over your budget by figuring out the magnitude of your stake.

Set limits

Setting limitations is another smart strategy for gambling that is similar to bankroll management. This applies to your cash as well as your desired playing time and/or winnings (if any). No matter how tempted you are, resist the urge to spend more than your designated bankroll if you have one.

If your bankroll runs out, try again another day rather than trying to recover your losses. You could end the game and make money if you set a goal for yourself and succeed in winning it after the first spin. Your account will get the funds immediately.
