Brief History of Slots

Slot machines have been the most popular casino games since they were invented way back in the late 1800s. Of course, those first games were a lot different from the ones you see today. The first slot machines essentially dealt you three cards and rewarded you with a non-cash prize if you ended up with a strong enough hand.

Slot machines were very controversial in the early to mid-twentieth century. While they appeared in places like beer halls, stores, and underground casinos, governments around the world waged war on them. This was particularly true in the United States, where government agencies seized and destroyed thousands of them. It was, however, a losing battle as those one-armed bandits continued to pop up in ever-increasing numbers.

Slots became the most popular attraction in land-based casinos in the latter half of the 1900s and 2000s. They are still the biggest draw at retail casinos. They also happen to be the most popular online casino games.

Even though many people associate online slots with real money, that isn’t always the case. You can play a wide range of free online slots too.

The games are ideal for anyone who wants to enjoy the thrill of slot machines without needing to risk any money. They are also perfect for those who want to learn how to play a specific slot game before committing real money.

Are Casino Slots Fair?

Slot machines have evolved in leaps and bounds since they were first invented. However, for the longest time, slot machines were mechanical.

As such, they were vulnerable to tampering. This eventually changed a few decades ago when they were essentially computerized.

Still, this didn’t stop the many crooks who would use an assortment of specialized tools to manipulate the machines.

The RNG is the heart and soul of any online real slots. This is an acronym for Random Number Generator, a computer program that uses highly technical algorithms and the like to produce a random result.

The RNG has determined the outcome as soon as you hit the spin button on a slot game.

Even though the reels are still spinning, the RNG has already decided whether you win or lose. The RNG doesn’t only determine the outcomes for slot spins, but it also determines the result of any other online casino game. Of course, this doesn’t apply to live dealer games.

Every online casino has a random number generator. Now, you may be wondering if those online casinos can rig these slots. This is where accredited third-party software auditors come into the picture.

Independent entities like eCOGRA, iTech Labs, and TST are among the most recognized software auditors. They test the Random Number Generators regularly to ensure they are always random.

Certification from one of the independent auditors means that the RNG is 100% fair and that the player or the online casino cannot manipulate it. So, these games can’t be rigged.

On the other hand, unlicensed online casinos that don’t have their RNGs audited and certified could possibly rig their games.

This is why it is important to stick with licensed online casinos with the relevant certification. This way, you know you’re getting a fair shake. You can normally find these certificates displayed at the bottom of an online casino’s main page.

Online Slots Features

Modern online video slots come in a wide range of shapes and sizes.

Whereas those old-time classic slots typically had three reels and a single payline, modern versions can have five, six, seven, or more reels along with multiple pay lines.

Old slot games mainly had fruit, gems, and numbers. These days, real money and free slots come in a massive range of themes. While fruits, gems, and lucky 7s are still popular, they have been replaced by other themes like:

• Ancient Egypt
• Mythology
• Television Shows
• Movies
• Music

Not only do these online slot machines feature a variety of themes, but a lot of them also have intriguing storylines and narratives that significantly add to the experience.

The Gonzo’s Quest and Narcos slot games are two good examples.

On top of that, many of these new online video slots feature mini-games. For instance, you can trigger a mini-game in Fishin‘ Frenzy in which you can literally reel in some pretty sweet cash prizes.

Real money and free online slots to play also have way morefeatures than the old clunky machines. In addition to an assortment of standard symbols, modern online slots feature scatters, wilds, expanding symbols, and extra spins.

Two games may look similar, but these special features make them unique. This is another reason why free online slots are so popular.

They give players a chance to learn the intricacies of particular games without having to worry about using real money.

Types of Free Slots to Play

The best online casinos showcase an array of video slot types. One of the most popular types of slot games is the progressive jackpot slot.

These games start with a jackpot, but the jackpot grows and grows until some lucky winner hits the magic combination.

So why does the jackpot keep getting bigger? Well, every time somebody places a bet, a portion of their wager contributes to the progressive jackpot.

Many of the most popular progressive jackpot slots are on large networks. In other words, you can have thousands of machines connected, which means thousands of players simultaneously contributing to the progressive jackpot.

Many of these jackpots have paid out well over $10 million. The biggest payout was over $20 million.

You can play many of these popular progressive jackpot slots for free, but you won’t be able to win the progressive jackpot or any other cash prize. You need to play for real money to have a shot at that.

Well, there is a way to win such a jackpot without risking any of your own money, but you’ll need to keep reading this guide to find out how.

With progressive games behind us for now, we’ll focus on some of the other popular free slots to play on mobile. One of the latest lines of online slot games is Megaways slots.

Some of the most popular Megaways titles include:

• Piggy Riches Megaways
• Bonanza Megaways
• Ted Megaways
• Monopoly Megaways
• Aztec Gold Megaways

As you can see, Megaways slots come in a variety of themes. They also have relatively high RTPs or Return To Player.

Most have an RTP of at least 96%. However, one of the most attractive aspects of these games is that they give players up to 117,649 ways to win.

Then there are the countless other free mobile video slots. As mentioned earlier, you can choose from dozens of themes and special features.

You can stick to the classic three-reels slots or spin five, six, or more reels at a time.

Who Makes the Best Online Slots?

Only a tiny handful of casino software providers created online slots in the early days of internet casinos. Games Global is perhaps the most notable software provider , primarily responsible for launching the first online casino.

If you were around those days, you might recall that there weren’t too many online slot machines to choose from. However, it’s also important to remember that all of this occurred before the mobile revolution, making it possible to play free slots on the go.

Since those first few online casinos went live, dozens of other top software providers have emerged. This has resulted in the creation of thousands of slot games.

Almost all games are now being designed specifically for mobile devices. Besides Games Global mentioned above, some of the most respected casino software providers include:

• NetEnt
• Games Global
• Play’n Go
• Big Time Gaming
• Yggdrasil
• ELK Studios
• Realtime Gaming
• IGT
• WMS
• SG Interactive

These and other top developers don’t just focus on pumping out games. They aim to create games of the highest quality.

They use the latest technologies to ensure their games have incredible HD graphics and a spectacular sound environment. Their games also run smoothly on any platform.

Volatility of Free Online Slots

You have probably heard the term “volatility” in relation to online slot games. If you aren’t sure what this means, then let’s explain it.

Some online video slots pay out frequently, but those payouts are generally small. These slots are generally considered low-volatility slot games.

Conversely, some online slot machines don’t pay out very often. However, they pay out well when they do. These are high-volatility slots. Then there are medium-volatility slots which fall somewhere in the middle.

Can I Win Real Money Playing Slots for Free?

This is perhaps the most common question regarding free online slots. The thing about playing free slots is that they typically don’t offer real prizes. Instead, you simply win or lose play money.

You will have to deposit real money for a chance to win real money prizes. You’ll also have to consider the terms and conditions of the casino where you play the slot of your choice.

Read these game terms before you start spinning to know when you have met all the criteria and are eligible for a withdrawal of your winnings.

In the responsible gambling context, it is equally important to realize that you may not win a decent cash prize everytime you play slots online.

Before logging into your casino account, decide on the money you can afford to spend, and potentially lose, on wagering. Stick to your fixed budget no matter what.
