Everything You Need to Know About Online Slots

Playing online slots for money has been legalized in several US states. The best online slots casinos will provide immersive gameplay, and they will contain stunning graphics to keep players entertained.

If you are diving into the world of online slots for the first time, there are a few things you will need to get to grips with. In the following section, we will look at the different types of real money online slots games, as well as the basics of how online slots function.

Types of Online Slots

If you are playing online slots to win real money in USA, you will want to play at the best online casinos. As you will discover, there are a few things that set apart the best online slots from the rest of the pack.

While some gamblers will gravitate towards a particular theme or jingle played on an online slot, others will discard that, and pick a slot that provides handsome wins. With that in mind, let’s take a closer look at the three different types of online casino slots you will find online slots reviews.

Video Slots

One of the most popular categories in the online casino industry is video slots. With video slots, there tends to be more animation to the gameplay, and they feature a more computerized version of your favorite games.

With video slots, you can unlock many special features, including scatters, where the player can access different bonuses, such as free spins. At Red Dog, you can tap into a wide range of the latest video slots, including 777 slots.

Progressive Jackpot Slots

Progressive jackpot slots see the jackpot grow each time a player spins. With real money online slots, each time a player spins a reel, their contribution will count towards the overall jackpot. The jackpot will continue to grow until someone wins it, and then the process starts all over again. Mega Moolah is one of the most well-known progressive jackpot slots around.

As they continue to grow at a rapid pace, it is not uncommon to see progressive jackpot slots pay out millions in dollars. The best slot games online will have a tiered system in place for progressive jackpots, ranging from mini through to the grand jackpot. Below, are the top 10 progressive jackpot slots, and the maximum jackpot they offer.

Progressive Jackpot title Software provider Max Jackpot
Megah Moolah Microgaming $1,000,000
Mega Fortune NetEnt $1,000,000
Immortal Romance Microgaming $1,000,000
Age of the Gods Playtech $500,000
Deal or No Deal Endemol $100,000
Jackpot Giant Online Slot Playtech $50,000
Wolf Gold Pragmatic Play $250,000
Divine Fortune NetEnt $300,000
Superman II Playtech $225,000
Gladiator Playtech $250,000

Classic 3 Reel Slots

Although not as popular as they once were, 3-reel slots have three columns attached. Players will bag a win if they can get three symbols matched up on the reels.

NetEnt is among the big software developers that serve up classic 3-reel slots at online casinos, and they are ultimately preferred by the purists. These nostalgic slots may have little in the way of bonus features, but there are plenty of paylines to capitalise on, and they still have their place. If you are a fan of 3-reel slots, you should check out Precious Treasures, A night with Cleo or Caesar’s Triumph, which are all served up at Bovada.

Caesar's Triumph are among the best 3-reel slots offered at Bovada

How Online Slots Work

It may come as little surprise that there is relatively little skill in mastering online slots. Slots can be bright, flashy, and fast, but they need not be confusing. Rather, real money slots online rely heavily on luck.

Real money online slots are played on a series of vertical reels, where you will find symbols. In every game, the reels will spin, and will stop randomly thanks to a random number generator (RNG). The randomness of these prevent games from being rigged, and RNGs are licensed by third parties. They are there to ensure fairness throughout the online slots casino.

To get started, you will need to select a bet credit, and the number of paylines you wish to wager on. If you elect to play with maximum betting credits, then this will make you eligible to win the progressive on specialty slot machines.

Once you have wagered a credit, you will need to pick the payline. Classic slot machines simply have reels that go straight across, while more contemporary online slots will have paylines, where you can win vertically, horizontally or diagonally. This is in part down to the scatter symbols where you can activate dozens of paylines. The more paylines you select to play, the more credits the online slot will require.

With online slots, there are a variety of key features, such as free spins or cascading reels. With the latter, winning symbols are taken out of play, and you receive a free re-spin. Consecutive winning cascades will be awarded a progressive multiplier. When it comes to taking out winnings, cryptocurencies are accepted, and they can expedite the withdrawal process.

Best Online Slots Software Providers

The best online slots casinos for real money win in USA will work closely with a wealth of top slots software providers to launch the latest titles to engage with gamblers. They will be truly immersive, and the experience will be seamless for those playing on either the desktop version of an online casino or on mobile no download online slots.

Either way, there are a plethora of renowned software developers, which you may have heard of. Below, we will give you the lowdown on each of them, and the sort of game titles that are flying off the production line.


Widely considered one of the best on the business, NetEnt’s origins lie in Scandinavia, and with headquarters in Sweden and Malta, they are renowned for producing state-of-the-art games. With over 200 games in the casino library, NetEnt has a proven track of creating slots and poker games.

No corners have been cut by NetEnt, and there are a raft of memorable online slots games in their roster, including Gonzo’s Quest and Starburst.


Since releasing their first online casino in 1994, Microgaming are a heavyweight in their own right, and they are known for producing games for land-based casinos as well. You can find it all at Microgaming from slots and tables games to software for live dealer suites, and multi-player titles.

Microgaming’s slot titles have been extensively reviewed, and while they may not be as dramatic as NetEnt, they are still a triumph. If you want to play slots online, you could well encounter a Microgaming title. Among the titles in its library, includes Mega Fortune, Divine Fortune, and Megah Moolah.


Also, another powerhouse featuring in this list, is Playtech. From its humble beginnings in 1999, Playtech rose to prominence quickly, and it has become one of the foremost developers of slots titles. Playtech prides itself on being able to produce cutting-edge games that will resonate with a wide casino audience.

Playtech has crossed over into the land-based casino environment, but when it comes to real money slots online, you can be guaranteed quality. There is a mixture of themes running through their titles, and there is a heavy focus on 3D graphics, and progressive jackpots. Some of the most popular Playtech titles you can try out, include Age of the Gods, and Superman II.

Pragmatic Play

One of the most venerable software developers in the world, Pragmatic Play has been delivering exceptional online slot games for many years, and they are certified, and licensed in over 20 jurisdictions. Pragmatic Play has tried to push the boundaries to make their games innovative, and mobile-focussed, and gamblers will have no qualms when they play one of their titles.

With over 200 HTML5 games at their disposal, Pragmatic Play provides an award-winning service. Among the titles offered by Pragmatic Play are Sweet Bonanza and Fruit Party.

Realtime Gaming

More commonly referred to in casino circles as RTG, Realtime Gaming are one of the biggest providers of online slot games on the Internet. If you are a regular online slots player, you will probably have heard of RTG, and you would have tried out their games.

Most RTG-powered casinos have myriad slots in relation to other games. While there may not be as many slot titles compared to Microgaming or NetEnt, games such as Cleopatra’s Gold, and Stardust are reputable, and they are free to play too.

Bonuses for Online Slots

Bonuses come in various forms and guises at online slots for real money. The best online slots casinos in USA will endeavour to roll out some exciting promotions, and offers, which will act as crowd pleasers. When you initially sign up, you may be entitled to several of qualibonus spins, and some of the best bonus slots, include Starburst and Riche Wilde & the Book of Dead. Winnings generated from free spins are paid as bonus cash, and you will need to fulfil all the wagering requirements before you can make a withdrawal.

So, with that in mind, let’s take a look at some of the bonus offers you may receive when you sign up to new online slot sites. We have also produced an eye-catching table below to illustrate some of the bonuses available at the aforementioned casino sites, and along with that, you can find details of promo codes and wagering requirements.

Matched Bonus

A slots site will match the deposit you place in your account with the same amount of bonus cash if it is a 100% bonus. So, if you pop $10 into your account, you will get a $10 bonus. If for example, you put $10 in for a 200% bonus, you will get $20 in cash. The top online slots will always offer matched bonuses, and they will have favorable terms and conditions. Cherry Casino comes up trumps for matched bonuses.

Cherry Casino offers an enticing matched bonus for new customers

Free Spins

When you open a new account, you will be able to use online slots for real money free spins on the games of your choice. However, at some sites, you must be wary that the online slots free spins offer may only apply to particular titles. Free Spins can sometimes be a standalone offer, while sometimes it may combine with a deposit bonus. Usually, you have to play through the qualifying game, and they have an average playthrough of 30x before they can be cashed out as winnings.

At Raging Bull, you can tap into the welcome bonus, and gain free spins on Fucanglong by entering the promo code ‘Bigger is Better’. But what is good here, is that the free spins don’t have any additional wagering requirements or come with delays for processing withdrawals.

Best Payout Online Slots

When it comes to best online slots payout percentage, variety is always paramount. However, RTP, which stands for ‘Return to player’ is critical for gauging how frequent a slot pays out. The best RTP slots will have an RTP of between 95 to 97%. In theory, the RTP shows how much money you would have after a prolonged gaming session. So, if you have $100 to wager with, and you are playing Starburst that has an RTP of 96.09%, you should have $96 remaining after the first hour.

Slots, as we know, can be highly volatile. Players can be prone to winning big or crashing hard, but RTPs are highly sophisticated. They are generated by supercomputers that have simulated millions of spins. RTPs are a good way to measure the effectiveness of the payout rate of a slot, and it is therefore more beneficial to play with a higher RTP than a lower RTP, as you will be able to pick up wins more consistently.

The RTPs of a slot can be found either through a quick google search or by visiting the online slots casinos where information about the RTP will be clearly displayed.

So, without further ado, let’s check out 10 of the best RTP slots which qualify as the best payout online slots in terms of return-to-player.

Slot title RTP
Blood Suckers 98%
Caesar’s Empire 97.50%
777 97%
Immortal Romance 96.86%
Dead or Alive 96.86%
Starburst 96.09%
Ancient Gods 96%
Book of Ra 96%
Gonzo’s Quest 95.97%
Cleopatra’s Gold 95.80%

Free Online Slots

Many casino operators will now allow you to play online slots games for free in the demo or practice mode. Ultimately, these are great as you can trial the game and decide which games best suit you before choosing which real money slots online to pursue.

Free online slots are supposed to be fun, and you can get a feel for the gameplay, and theme before parting ways with your hard-earned cash. Some of the best free online slots will be available at the casinos we have mentioned in this guide, including Ignition which also offers Bitcoin slot machine games

There are several benefits attached to trying out free slots online before playing for real money, and this includes:

  • Study advanced paylines – Some of the slots will enable you to figure out how different paylines can be created, and within that, you can focus on your own strategy.

Of course, there are some downsides too with practicing slots online for free:

  • No bonus offers – If you have a fully-fledged account, you will be able to access some of the most generous bonuses, and the best online slots to win real money will offer matched deposit bonuses or free spins.
  • Limited slot game variety – Essentially, when you try slots in demo mode, you won’t be able to advance too far in the game without playing for real money. This can to a certain extent, become repetitive over time.
  • Minimal customer support – While account holders will be able to call upon customer support through a variety of measures, if you are playing in demo mode, you will generally be overlooked by the casino site until you sign up.

Top Tips for Playing Online Slots Real Money

Playing online slots games that pay real money can be a thrilling experience. And if you want to get the most out of them, here are five top tips to ensure that your time spent reel-spinning is a fruitful one.

Don’t get trapped in a slotting rut – It can be very easy to get too bogged down playing the same slots, and not get much joy from them. Instead, shake things up a little, and explore new slot titles or slots sites to make things more exciting.

Take advantage of bonuses – If you are playing new slots sites, you will be deluged with welcome offers. Some of these bonuses will enable you to bet without the risk of losing your own cash.

Manage your bankroll – Always bet within means, and don’t bet more than you can afford. Ultimately playing slots should be fun. So, when the fun stops, stop!

Don’t Play when you are tired – While poker players can tilt when they make bad decisions or they are overly emotional, the same principle hard earned applies to playing slots for real money. Always play when you are at your sharpest, as you need to be level-headed. If you are feeling tired, take a break and come back to the slots when you are feeling refreshed.


Real money slots have become a staple of the online casino world. With more and more titles being released on a regular basis, players are spoilt for choice as to which games to play. Of course, 3-reel slots still have their place and are relevant. However, those who want to challenge themselves may opt for 5-reel slots that come with an abundance of pay lines.
