Online Slots – Brief History

HistoryEver heard of Charles Fey? He is the founder of contemporary slot machines. Fey, born in San Francisco in the 19th century, created the first slot machine. This completely changed the gaming industry.

Fey’s creation made fruit machines one of the most played casino games in the world today. His creation of the automatic payment system was his most important contribution to the evolution of fruit machines.

Before this, casino operators paid out profits from slot machines manually. As you might have thought, this was frequently inefficient and time-consuming.
Fey's automated payment system streamlined the process for casino owners. It also simplified the way players get their winnings.

While Charles invented the slot machine, Herbert Mills advanced and refined the idea of the slot machine. Mills improved Fey's Liberty Bell design when he unveiled the Operator Bell Machine in 1907. It soon rose to prominence as one of the most well-liked fruit machines.

1994 saw the creation of the first online slot machine by Microgaming. “The Gaming Club” was the name of this straightforward three-reel slot machine with a single payline. Even though it seems archaic by today's standards, it was a significant innovation at the time.

Not long after “The Gaming Club” was introduced, other software developers started creating their online slots. NetEnt was a prominent player in the online slot industry, having launched its inaugural game in 1996. With five reels and nine paylines, this game—named “NetEnt's Casino”—represented a significant advancement in both gameplay and graphics.

Since then, hundreds of software developers have entered the scene. Currently, there are thousands of online slot games hosted on hundreds of slot sites.

How to Pick the Best Slot Sites

Not all online casinos with slots offer the same gaming experience. Here are some of the things to look out for before signing up at a casino offering slot games:


Legitimacy of the Casino

First, ensure the gaming platform has a license from a reputable regulatory body such as the UKGC, Kahnawake, Curacao, and the MGA. Also, only consider sites operated by a company with an excellent reputation. Most casinos usually display the operator’s name and licensing information at the footer of their homepage.


Number of Slot Games

Being a slots lover, you don’t want to play at an online gambling platform with just a handful of slot machines. Instead, go for a casino with thousands of slot games. This way, you’ll have a wide variety of slots to choose from.


Is the Slot Site Mobile-friendly?

Nowadays, discussing mobile compatibility in online casinos is cliché. If an online casino doesn’t have a mobile app, it should at least have a mobile web-based version. This will allow you to play your favorite slot machines on the go.


Payment Methods Available?

If you’re playing slots for real money, you may need to cash out after winning. This calls for secure and fast banking options such as cryptocurrencies and e-wallets. To get your winnings when you need them, consider a slot website with reliable and even local payment methods.


Does the Slot Site Offer Bonuses?

Casino bonuses boost your playtime, allowing you to play for longer and possibly win big. So, go for online slot sites with a variety of bonuses, such as free spins. The bonuses should be worthwhile in that they have reasonable wagering requirements, and you can use them to play a variety of slots.

How Casino Slots Work

How Casino Slots WorkOriginally, slots were just digital reproductions of the slot machines you might have seen at gaming halls or real-world casinos. Since then, game creators have developed inventive themes, features, and other gameplay components. Slots are currently the most played casino game online because of these qualities.

Conventional online slots comprise reels that display a variety of symbols. The symbols must form a winning combination on an active win line for your bet to bear fruit.

Additionally, they might have unique characteristics that can be activated at random or in response to the landing of a predetermined quantity of special symbols. Free spins and other extra features are the most popular examples of these.

In addition to other creative features, many contemporary online slots have unique gaming components like cluster payouts. These allow winning combos to be formed by groups of symbols contacting one another. You may discover almost anything among the hundreds of firms that have produced thousands of casino games.

The house edge, or advantage the casino has over its patrons, is the result of how slot machines are set up. Online slot machine house edges often hover around 4%, meaning that over the long haul, gamblers lose 4% of their initial stake. Nevertheless, the house edge may vary based on the particular slot machine and online slot site.

The term payout ratio, or return to player (RTP), refers to the percentage of risk funds that players can reasonably anticipate receiving back as individual wins. It is computed as 100% minus the house edge. The RTP of games with a 4% house edge is 96%.

On the other hand, variance, sometimes referred to as volatility, describes the frequency and size of individual wins when playing a particular slot machine. Large wins are possible on high-volatility slots, but successful spins are typically less common. You can win more often on low volatility slots, but the size of each win is typically smaller.

Types of Slots at Online Casinos

With thousands of online slot games, it makes sense to categorize them into different divisions. Here are the broad classes of slot games to help you find your preferred one faster:

Classic Slots

Classic slotsIf you love to keep things simple, consider classic slot games. These games most closely resemble the original slot machines first introduced in physical casinos.

Typically, most classic slots have 3 reels and feature a horizontal payline stretching across those reels.

Most of them are fruit-themed. You’ll come across fruit symbols such as cherries, lemons, and oranges in these slot games. Additional symbols could be bells, bars, or Lucky 7s.

Typically, these stripped-down slots have no additional features. But certain three-reel slots may occasionally have bonus games, wild symbols, and scatter symbols.

Some of the best classic slot machines today are:

  • Bell of Fortune
  • Monkey Madness
  • Arcade
  • Fruit Mania
  • Jackpot Cherries

3D Slots

Certain software developers, such as NetEnt and Endorphina, have added 3D effects to some of their games. 3D slots offer amazing animations, improved sound effects, captivating features, and excellent graphics.

The only catch with 3D slots at the best online slot sites is you’ll need a stable internet connection. This way, you’ll get the most out of your online 3D slot machine experience.

Compared to most slot variants, 3D slot machines come with a wide variety of themes and subjects. Here are some of the 3D slots you’ll come across at the best slot sites:

  • Dead or Alive
  • Fury of Zeus
  • Cyberpunk City
  • Jurassic Park Remastered
  • Play with Cleo

Megaways Slots

Megaways SlotsA slot machine designed using the Megaways mechanism is called a Megaways slot. There are more possible winning ways thanks to this mechanism, with the paylines going even up to 117,649.

It is important to note, though, that not every Megaways slot machine has 117,649 ways to win. There are 248,832 ways to win in White Rabbit and 586,971 Megaways in Holy Diver. That is, assuming you can get beyond the bonus game.

A Megaways slot machine's winning formula differs from a regular slot machine's. With Megaways, winning doesn't require aligning symbols along the designated payline. Rather, it just requires matching symbols to land on neighboring reels, going from left to right.

Here are some of the notable megaways slots at the top slot sites:

  • Judgement Day
  • Book of Tut
  • Savage Buffalo
  • Cashpot Kegs
  • Masks of Fortune

Progressive Jackpot Slots

Progressive Jackpot SlotsJackpot slot games allow you to win jackpots inside a single game. This gives you more than just one shot to win the big prize.

Progressive jackpot slots, as their name implies, offer jackpots with continually growing values. This is what makes them a favorite among most gamblers. They’re unlike typical jackpot slot games with fixed jackpots defined by the players’ bets and the symbol values.

There are 3 types of progressive jackpot slots:

  • Local Progressive Jackpot Slots – Also called proprietary progressive or in-house slots, local jackpot slots are interconnected slot games hosted by one casino. While they might not pay out millions of dollars, they deliver substantial gains.
  • Stand-Alone Progressive Jackpot Slots – Mostly available in land-based casinos, a stand-alone progressive jackpot is the reward you get from a single video slot machine by playing over time. As a new player signs up for it, the pot grows.
  • WAN Jackpot Slots – In full, you can refer to this type of jackpot slot as a Wide Area Network jackpot slot. Here, every game connected contributes to the same jackpot reward. But it’s the manufacturer and not the casino that pays out the rewards.

VR Slots

Virtual Reality slots and 3D slot machines are different. The primary distinction between 3D and VR slots is that 3D slots don't require a headset to play. Before participating in virtual reality slots, you must have the necessary gear. Usually, this consists of just two controllers, a VR headset, and an account to register the gear.

VR allows you to see a slot game from a new angle and immerse yourself in it. It feels as though you are actually there, inside the game, observing everything surrounding you. You’ll get the feeling of being in a physical casino.

Here are some of the VR slots at the best slot sites:

  • Starburst VR
  • Gonzo’s Quest VR
  • Jack and the Beanstalk
  • Sugar Rush VR
  • Miss Midas

Common Slots Features

You'll encounter a wide variety of slot features as you play more games at the top slot sites. We’ve mentioned some of the most well-known features here. Notably, game creators are always battling to either create brand-new features or enhance those that they already have.

Table of contents


One of the most common symbols you’ll find in online slots is the wild. They’re usually in the form of the game’s logo or the slot’s hero, depending on the theme. Wilds replace other symbols to form winning combinations.

There are several guidelines that cut across wild symbols. The major one is these symbols can’t replace the scatter (more on this later). Some wild symbols act as scatters. That means, besides standing in for other symbols, they trigger free spins.

The following are types of wild symbols you might come across in different online slot games:

Sticky Wilds

These are among the most profitable symbols in slot machines. As their name implies, they stick around for multiple spins. This allows you to form an enormous number of winning paylines from several spins.

Sticky wilds are also called frozen or locked wilds. Ooh Aah Dracula and Dead or Alive 1 are among the slot machines featuring these wilds.

Stacked Wilds

You’ll mostly find stacked wilds in slot machines with numerous paylines and typically high volatility. The wilds can, as their name implies, stack on top of one another. In turn, this provides you with numerous opportunities to win.

Iron Man and Money Train are great examples of online slot games with stacked wilds. The former comes with 5 reels and 20 paylines. Meanwhile, Money Train has 5 reels and 40 paylines.

Colossal Wilds

Compared to other reel symbols, Colossal Wild symbols are substantially greater in size. Frequently, they cover one or more reel positions. This implies that you might spin them on separate reels.

Since colossal wilds frequently cover more than one reel, they come with enormous winning payouts. Spinata Grande and Twisted Sister are some of the slot machines with this type of wild symbol.

Expanding Wilds

As their name suggests, these wilds expand on a reel from top to bottom. Ultimately, each symbol on the reel becomes a wild. This may result in several wins across multiple paylines.

When the symbol expands, every winning combination formed increases your bankroll. This can lead to enormous rewards if the wilds are involved in several profitable combos. Double Dragon, Lucky Lager, and Black Knight are some top slots with expanding wilds.


Be on the lookout for the scatter symbol. Some of them come in the form of game characters, while others are icons with the name SCATTER on them. Not all slots have this symbol, though.

The scatters' capacity to launch bonus games is what makes them such wonderful companions. They can trigger mini-games, free spins, or bonus rounds.
You may need to land a certain number of scatters to activate free spins. While this may differ across slot machines, most slots usually require you to land at least 3 of them.

In most games with wild symbols, you’ll likely come across scatters. Some of the slots with scatter symbols are:

  • Ultra Blazing Fire Link
  • Fortune Coin
  • Gates of Olympus
  • Golden Goddess
  • Eagle Bucks


As their name implies, multipliers are unique features that multiply your winnings by a certain figure. They usually come with a predetermined figure and an “X”. For example, 100x means your winnings will be multiplied by 100.

Multipliers are uncommon in base games. This does not imply that there aren't any multipliers in base games. In fact, a large number of slots do.

It’s not surprising to see wild symbols that come with multipliers. You may even come across scatters that have multipliers.

Here are examples of slot machines with multipliers:

  • Hula Balua – up to 200x
  • Nitropolis 4 -up to 12x
  • Razor Returns – up to 25x
  • Bigger Bass Blizzard – up to 10x

Free Spins

As their name implies, free spins are special bonus features that allow you to spin reels for free. Free spins in online slots, as mentioned, are usually tied to scatter symbols. Most slot machines, such as Wonder Roses, give you 10 free spins when you land three scatters.

You can also get free spins from special symbols such as sticky wilds. This, however, applies to a few online slot games. Usually, sticky wild symbols adhere to the reels to complete a winning combo. Consequently, they may trigger 2 to 5 free spins.

Remarkably, the scatter symbol pays out the highest. The ring, Chalise, timer, and crown come next. You’ll also come across a set of jewels that are the lowest-paying symbols.

The Tumble Feature is most likely the one you'll encounter the most. This feature allows symbols to fall and new ones to replace them. It goes on until there are no more winning combinations.

Thanks to the best online slot sites, you don’t have to shop for fish. Everything is hands-on – so get your fishing line and cast it out to the ocean for some white meat! You may come across some hidden treasures in the process.

A fisherman is the wild symbol, replacing all other symbols to form winning combos. Notably, when you land 3, 4, or 5 scatters, you’ll get 10, 15, and 20 free spins, respectively.

During the free spins, the fisherman can increase the multiplier to 10x or trigger the Dynamite Feature. This feature changes any symbol to fish symbols.

Volatility in Online Slots

You may have come across the term “volatility” when checking out the stats of a slot. You shouldn’t confuse it with RTP (more on this later). Volatility is entirely different. You can call it variance or, in general, Volatility Index (VI).

Volatility is the measure of the frequency of wins and average win amounts on a given slot machine. There are three divisions of volatility – low, medium, and high. You may also come across slots with low-medium and medium-high volatility.

Online Slots With Low Volatility

A slot machine with low volatility will often pay out modest wins quickly. Simply put, you’ll get small wins frequently. Here are some of the slots with low volatility:

  • Wheel of Wishes
  • Starburst
  • Major Millions
  • Agent Jane Blonde Returns
  • Jackpot Raiders

Low-Medium Volatility Slots

Low-medium slot machines are the middle ground for gamblers who are on the fence between low and medium variance slots. You should expect smaller winnings when playing low-to-medium slot machines.

Are you willing to take a chance on some significant prizes with an above-average budget? Your best option, if such, would be a low to medium-volatile slot machine.

Here are some of the best low-medium slot games you can enjoy:

  • Zorbas Tavern
  • Stacked
  • Sizzling Mystery
  • Booming Seven Deluxe
  • 7 Monkeys

High Volatility Slots

Meanwhile, a slot game with high volatility will usually pay out large wins spaced apart. That means you’ll get significant payouts less frequently. The following slot machines have high volatility:

  • Legacy of Dead
  • Mental
  • Bonanza Billion
  • The Dog House Megaways
  • Area Link Piggy Bank

Medium Volatility Slots

Medium-volatile slot machines, as you may have guessed, fall in between. They balance the timeframes of big and small wins. The best part about them is that they offer higher rewards than low-variance slots, and wins come more often than high-variance slots.

Here are popular titles with medium volatility:

  • 9 Masks of Fire
  • Immortal Romance
  • Cosmic Coins
  • Wacky Panda
  • Ramses Book

Medium-High Volatility Slots

As you may expect, medium-high volatility slots pay out somewhat less than highly volatile slots. Here’s the best part: expect more frequent payouts than you would in a slot machine with high volatility.

In a nutshell, slot machines with medium-high volatility are excellent for players who want to pursue big pots. They’re also ideal for gamblers who don’t want to take on a lot of risks.
Here are some of the medium-high volatility slots to get you started:

  • Payout Time!
  • Aloha King Elvis
  • Amazing Link Riches
  • More Magic Apple
  • Raging Rex 2

All slots, meanwhile, have the potential to pay out both modest and large wins. The frequency of payouts is simply indicated by where the slot is located on the Volatility Index (VI).

RTP in Slots – What Is It?

Slot games have unique RTPs. Also called Return To Player, RTP is the amount you can expect to win from a slot machine over the long haul. It’s usually expressed as a percentage.

How RTP in Slots Work

How RTP in Slots WorkBefore digging into how slot RTPs work, it’s worth mentioning that it’s just a theoretical statistical calculation. This is not a short-term, instantaneous metric. It is a representation of the anticipated performance over a very large number of spins, usually millions.

A slot machine's spins are discrete, random events that happen separately from each other. This is made possible by a mechanism known as a random number generator (RNG).

RNGs are computing algorithms that generate random numbers. This guarantees complete randomness and fairness in every slot machine spin.
The RTP shapes the payout structure of the game. However, it has no direct effect on the outcome of any given spin.

Say you play a game with a 95% RTP at an online slots real money casino. Basically, this means you should expect €/$95 for every €/$100 you spend. This does not, however, imply that you will earn back that amount of money when playing.

Let’s take Wheel of Wishes, a low-volatility slot from Alchemy Gaming with an RTP of 93.34%. If players wagered €/$ 1,000,000 over millions of spins, the total RTP would be 933,400. The remaining 66,600 would be the house edge (what the casino keeps).

This does not mean, though, that every gambler who wagers $100 will receive a precise return of $6.66. While one person can win a lot of money, another might not get a single return.

RTP & Volatility

“Slot volatility refers to the risk involved in a specific slot game. Slots with high volatility have higher risk and bigger, less frequent payouts. Because they might skew the balance with their large rewards, they frequently have lower RTPs. Low volatility slots, on the other hand, give lower but more frequent rewards. Since there is a higher chance of returns, their RTPs are usually higher.”

Online Slots with the Highest RTP

First off, you’ll hardly find a slot machine with a 100% RTP. It’s next to impossible because the house edge, in this case, would be 0%. That’s a loss to the online casino.

The highest RTP you’ll find at the best slot sites is 99%. Here are some of the online slot games at the best online casinos with the highest Return To Player:

Mega JokerThe Mega Joker we’re talking about here is that from NetEnt. Just a clarification because there’s another Mega Joker from Novomatic with an RTP of 95.05%.

NetEnt’s Mega Joker is a high-RTP slot that debuted in 2013. So, as you may expect, it’s a traditional game with old-fashioned graphics. But don’t let the graphics fool you because it’s a highly interesting game.

The RTP of the game does have a tiny catch, though: it only fully activates when you play with maximum money bets. If not, the RTP of the game is as low as 85%. Nonetheless, you can get the game's progressive jackpot even when you bet the minimum amount.

Top Tips to Play and Win in Slots

Expert tipsHave you ever come across a website promising you a lucrative secret slot strategy? You shouldn’t expect anything like that here.

Honestly speaking, it’s nearly impossible to win money on slots continuously. That’s because these are luck-based games that you don’t have control over. The

Random Number Generators used make it hard to beat slot machines.

There are, however, a few strategies you can apply that will give you an upper hand. These include:

Avoid Bets That Reduce RTP

Avoid Bets That Reduce RTP

Most online slots offer the same RTP for all types of wagers. Some slots, though, that are adapted from brick-and-mortar slot machines seriously disadvantage specific wagers. In this situation, you should always select the wager type that has the fewest drawbacks. Here’s an example: It costs two cents to wager on all three winlines and one cent to wager on just one. Apparently, placing a wager on a single line will have a low RTP. As a result, it is usually advantageous to go with the two-cent wager.

Decrease the Number of Paylines

Decrease the Number of Paylines

Did you know that decreasing the number of paylines increases a slot’s volatility? Let’s say you set a slot game to 1 payline instead of, say, 10. In this case, you’re likely to get a higher variance of up to 10 times. Here’s another example: If you bet $2 on a single payline, you’ll get high and less-frequent wins. That’s unlike betting $0.2 on 10 paylines that will give you a 10x smaller paytable. Keep in mind that high rollers typically cannot employ this strategy because there’s a limit on the bet per line. However, some slots are an exception, such as IGT's Cleopatra.

Play Games With the Gamble Feature

Play Games With the Gamble Feature

After winning on a slot, the double-up feature allows you to gamble your winnings. If you’re lucky, the gamble feature can double your wins. However, if luck is not on your side, things may go south, and you lose your winnings. Usually, the gamble feature increases the game’s volatility. The only drawback is some casinos forbid using this feature if you’re using a bonus.
