Online Slot Games Software Providers

A series of software developers provide online slot games to casino sites. Typically, one set of providers offers slots to offshore online casinos, while another set provides games to licensed and legal online casino sites. Below are some of the top design houses in each category.

RTG Slot Games

RealTime Gaming launched in 1998 in Atlanta, Georgia. Since the UIGEA law went into effect in 2006, RTG has been based out of Heredia, Costa Rica. No other slot provider is in more US online casinos, so you might have played famous RTG slots like Achilles, Rudolph’s Revenge, Bubble Bubble 3, and Cash Bandits 3.

If you prefer progressive online slots, then you might have played Aztec’s Millions, Megasaur, Jackpot Pinatas, or Jackpot Cleopatra’s Gold.

Microgaming Slot Games

Microgaming was one of the first online slot designers, launching all the way back in 1994. Among the international slot providers, Microgaming is known for slots like Mega Moolah, Avalon II, Pharaoh’s Fortune, and Thunderstruck II. Microgaming developed some of the internet’s biggest progressive jackpot slots, as well as a bunch of licensed online slots.

Playtech Slot Games

Playtech began in 1999 as a top rival to Microgaming and now is featured in hundreds of international online casinos. Hence, Playtech is known for slot series like Age of the Gods, Book of Kings, Kingdoms Rise, Fountain of Youth, Neptune’s Kingdom, and Buffalo Blitz. If you like licensed slots, Playtech offers games like Ace Ventura, Grease, and Marilyn Monroe.

Betsoft Slot Games

Betsoft is a top competitor for RTG in the offshore US online casino market. The company’s specialty is slick graphics, while design houses like Nucleus Gaming often provide a lot of slots to online casinos, too. Several Betsoft slots have high RTPs, such as Good Girl Bad Girl and Greedy Goblins. It also produced fun series such as Max Quest, Alkemor’s Tower, Sugar Pop, Rook’s Revenge, and Safari Sam.

NetEnt Slot Games

Net Entertainment started later than Microgaming and Playtech, but it was the online slot designer tied to Sweden’s famous land-based slots company, Cherry. These days, NetEnt is known for big jackpots, 3D graphics, and licensed slots.

If you’ve played slots like Blood Suckers II, Starburst, Jack Hammer, and Gonzo’s Quest, you’ve played NetEnt games. Its licensed slots list includes many games, including Guns N’ Roses, Jimi Hendrix, Hell’s Kitchen, Knight Rider, and Jumanji.

Rival Gaming Slots

One of the top slot providers in the offshore online casino market for US players is Rival Gaming. Due to its huge number of fun game features and solid jackpots, Rival Slots have a good reputation among US and international slot players. Famous Rival slots include games like Five Times Wins, Scary Rich 2, Golden Gorilla, and Arabian Tales.

IGT Slot Games

International Game Technology is better known as IGT. The Las Vegas slot developer is the biggest name in land-based slot machines, while it has a significant impact on licensed online casinos, too. IGT is known for its progressive jackpot games like MegaBucks and Wheel of Fortune.

Online players might have played IGT games like Da Vinci Diamonds, Cleopatra II, Kitty Glitter, and Hexbreaker III. Or you might have played some IGT’s licensed slots like Baywatch, Bill & Ted’s Excellent Adventure, Jeopardy, and The Price Is Right. Whatever the case, many players equate IGT with the best Vegas slots.

Aristocrat Slot Games

Aristocrat Leisure began way back in the 1950s and became the top Australian online slot manufacturer (where slots are called “pokies”). In the 21st Century, Aristocrat expanded into the international brick-and-mortar slot machine market. Now, Aristocrat Leisure slots are popular in US commercial and tribal casinos.

If you’ve played North American real money slots, then you’ve probably played Aristocrat slots. Top games include Buffalo Slots, 50 Lions, Lightning Link, 50 Dragons, Queen of the Nile II, and Choy Sun Doa. Also, Aristocrat produces lots of licensed slots, including Dumb and Dumber, Elvira, Downton Abbey, Batgirl & Catwoman, Mariah Carey, Madonna, Sharknado, and Superman: Man of Steel.

  • Slot Tips: First, find real money slots with high RTPs, don’t fall for slot strategy schemes, use money management tips, and avoid progressive betting.

  • How to Win: Finally, play popular online slots, choose slots with smaller jackpots, and find games with bonus rounds, free spins, and multipliers.

Slot Machine Strategy Tips

One reason for the popularity of slots is the fact they don’t require strategy. No basic strategy charts exist, and no memorization method can help increase your odds. At the same time, varying your bets won’t help. That said, online slot players can do certain things to help their chances. Follow the basic online slot tips to give yourself the best chance of winning.

    • Go for Smaller Jackpots: As a rule, the smaller the jackpot, the better the return-to-player (RTP) is on the slot game. If you don’t know the RTP, go for the smaller jackpot.
    • Play the Classic Games: Play popular online slot games. Such games tend to be popular for one of two reasons: (1) it has better odds or (2) it has a bigger jackpot.
    • Stick to Safe Slot Casinos: When you go for real money, play online slots at the most trusted and reliable casino sites. Pick sites with a reputation for fun games and quick payouts.
    • Look for Bonus Rounds: Play real money online slots that have one or more bonus rounds. These offer free spins, multipliers, and big jackpots with no risk to your bankroll.

The Loosest Slots in US Licensed Casinos in 2023

The following list includes the best online slots in the licensed casino market, according to return-to-player (RTP) percentage. The RTP is closely related to the payout percentage, which we discuss in greater detail below.

Slot Game


Return to Player

Avalon II NetEnt 97%
Guns ‘N Roses NetEnt 96.98%
Thunderstruck II Microgaming 96.65%
Wheel of Fortune IGT 96.60%
Mega Fortune NetEnt 96.40%

Wizard of Oz NetEnt 95.99%
Flaming Hot EGT (Euro Games Technology) 95.53%
Book of Ra Deluxe Novomatic 95.50%
Triple Diamond IGT 95.06%

What is a Payout Percentage?

The payout percentage is the amount of money a slot machine pays out based on a percentage of what you bet. The percentage is based on a theoretical $100 wagered, with the amount paid back often referred to as the return-to-player or “RTP”. Since casinos have a built-in advantage to most of their games, the RTP is usually less than 100%.

When it is, the house edge is the amount the casino can expect to win when $100 is bet. Thus, the RTP and house edge combine to make 100%. If the payout percentage or RTP is 98%, then the house edge would be 2%. In the various tables below, we highlight the RTP of the best real-money online slot games. The higher the RTP, the better it is.

Online Slots Real Money FAQ

How do online slots work?

Online slots use a random number generator (RNG), the same way brick-and-mortar slots have worked since the 1980s. When you make a wager and hit “Spin”, the RNG produces randomized results based on mathematical probability. This allows real money online slots to have a wide range of results while offering huge jackpots. Sometimes, slot games offer progressive jackpots.

Can I play slots online for real money?

Absolutely, you can play real money online slots at casino sites. The key thing is to find a real money online casino. If you download a free casino app from Zynga or you play slots on a social media site, you won’t be able to play for real money. Instead, you’ll play free slots that keep track among friends or on a leaderboard.

That’s not enough for most players. In that case, you want to sign up at a real money casino and make a deposit. Once you do, you can play slots online for real money. The best US online casinos have hundreds of slots online.

What online slots pay real money?

The online slots at real money casinos pay out in cash. Once you fund your account and accept a welcome bonus, you’ll be able to play slots for real money. That only happens at real money online casinos like Super Slots, Planet 7 Casino, Wild Casino, or Slots Empire. These sites have a selection of 3-reel spinners, 5-reel video slots, 3D slots, licensed slots, and even progressive slots.

How do I play slots online for real money?

You’ll want to take several steps to play online slots for real money. First, research real money online casinos by reading casino reviews and player forums for other players’ ratings. Next, choose an online slot casino and register for a player account. Next, visit the cashier page to make a real money deposit using your favorite payment method. The banking options include credit cards, debit cards, web wallets, Bitcoin and other cryptocurrencies, bank wire transfers, money orders, and cashier’s checks.

Once you’ve signed into your account and made a deposit, you’ll be offered one of several welcome bonuses. Pick the one best for your (first-deposit bonus, crypto bonus, free spins bonus) and read the wagering requirement and terms of use. Once you pick a game that clears the requirement, play real money online slots until you clear the requirement.

After this, you’ll want to make a withdrawal of your real money winnings. Visit the cashier page and pick a withdrawal method, then request a payout. Wait a few minutes to a few days for your real money online slot winnings.

Are there any online slots that pay real money?

Certainly, but you’ll want games from certain companies. Play online slots from RealTime Gaming (RTG), Rival Gaming, Betsoft Games, Nucleus Gaming, Dragon Games, Spinomenal, or Woohoo Games. These companies make real money online slots for the best US online casinos.

Alternately, players can seek out real money slots online from IGT, WMS, Bally, Konami, Playtech, Microgaming, NetEnt, and Aristocrat. The problem with these slot developers is they supply games to licensed online casinos. These sites only accept real money play in 5 US slots, so it’s hard to find real money online slots from IGT and Aristocrat.

Can you play slot machines online for real money?

Yes, but at only certain types of sites. Social media sites, social gaming sites, sweepstakes casinos, and free mobile casino apps like Zynga don’t offer real money slots play. Instead, they offer free-to-play slots where you keep track of friends’ or other players’ results. That’s not much fun with slots, so you’ll want to go to a real money online casino or mobile slots casino.

How to play real slots online for money?

Visit real money online slot casinos like Super Slots, Wild Casino, Slots of Vegas, or Comic Play Casino. All of these accept US players from all 50 states, and they accept real-money online slot players from all states. Real money slot gaming at offshore online casinos is legal in all 50 states.

What online slots pay out real money?

The online slots at real money online casinos pay out real cash. At most other sites, you won’t be able to play for real money. Hence, these sites have mobile slots for real money, often without requiring a mobile slots download.

Can I play slots for free?

Absolutely, you can play real money slots for free. Online casinos offer free versions of their games in practice mode for promotional reasons. Thus, the site hopes you try the game, enjoy it, and decide to play for real money for the sake of thrills.

What should I look for in an online slot casino?

Look for a trustworthy casino with hundreds of slots, fair terms of use, and reliable payouts. Later, combine these with the payment types you prefer and a lucrative bonus and you have the perfect real money online slot casino.

What’s a progressive jackpot?

It’s a jackpot that accumulates every time someone plays and doesn’t hit the grand prize. If you bet $1.00 and don’t win the progressive jackpot, then a certain percentage of the bet (let’s say $0.05) grows the jackpot. With wide-area jackpots, many players’ sessions feed the same progressive pot. Over time, this grows into hundreds of thousands or even millions of dollars. When a lucky player hits the right reel combination (royal flush), they win a life-changing prize amount.

Can I win real money playing online slots?

The only place you can win real money playing online slots is at a real money online casino. Doubtlessly, social gaming sites and sweepstakes casinos exist that offer games for fun. These might be good to play with friends, but it’s real money online casinos that have the slots with the biggest jackpots.

Are online slot casinos trustworthy?

Certainly, but only if you do the research to find honest online slot casinos. Don’t put your money into a site without reading reviews and learning about the site’s reputation. You can find safe and trustworthy slot sites in the regulated gaming market and the offshore online casino market. Hence, you’ll need to do a bit of research before depositing your cash.

How do welcome bonuses work?

When you make a deposit and input a promo code, the casino matches every dollar you deposit with a certain amount of money. With a 100% deposit bonus, your deposit is matched $1 for $1. For a 200% welcome bonus, every dollar you deposit is matched with $2 in bonus cash. Most sites have a deposit minimum to trigger the bonus and a max deposit where the bonus funds are capped.

However, welcome bonuses have terms of use called a “wagering requirement”. This means you must wager the bonus a certain number of times — called a playthrough or rollover — before you can withdraw the cash. Thus, if you receive a $500 bonus and have a 20x wagering requirement, you’ll need to wager $10,000 before making a withdrawal.

That might sound like a lot, but remember the expected return on slot bets. If you find a real money online slot with a 97% RTP, then you would expect to lose $3 on every $100 wagered. You would expect to lose $300 if you wagered $10,000, which means you would expect to pocket $200 of your bonus cash. Due to variance, you might walk away with more or you might have none left once finished. Thus, you’ll need to get lucky.

Which online slots pay out the most?

When it comes to online slots, it’s the games with the best RTP that pay out the most. That often is games with low fixed jackpots, but it doesn’t have to be. Read our list of the best online slots according to RTP above to see which online slots pay out the most.

How do I pick a winning slot machine?

Ignore advice about loose slots and zigzag methods. First, read through our list of the best online slots according to find the titles with the best odds. Second, find online casinos that have those titles. Once again, we offer suggestions when it comes to the best casino sites for certain slot software providers. Finally, read our analysis and you can track down the online slots with the best odds.

Are online slots rigged?

In fact, the vast majority of online slots aren’t rigged. Whereas rogue casinos might take your money once or twice, honest casinos play with a house edge. As long as the game is fair, the casino has a built-in advantage. While that doesn’t assure you’ll lose money, it all but assures that the casino will make money over time. With a house edge, a casino would be crazy to cheat its customers.

Obviously, the internet is a source of information. So if rogue casinos steal people’s money, those people will spread the word online. Read about blacklisted casinos and avoid those sites. Read online casino reviews to find the safest, best slot sites.

How do I pick a good slot machine?

In brief, read game reviews based on the slot machines you expect to play. And if you plan on visiting a land-based casino, visit their website and learn what slot machines they have. Once you do, pick the titles with the best-published return-to-player (RTP) stats.

For the same reason, if you plan to play online, read online slot game reviews. Learn the software providers at your chosen online casino, then find the best games that slot designers offer. Once you have an account, play the online slots with the best real-money odds.

Which US states have legalized gambling?

Because all 50 states have the right to set their guidelines, the US is a patchwork of gambling laws. States like Utah and Hawaii have a 100% ban on gambling, while others allow most forms of gambling. Some states have legal online sportsbooks, though only 6 states have licensed online casinos.

Nevertheless, US residents can gamble online legally in all 50 states. While states might ban a resident from launching their own online gambling portal and collecting revenues, that doesn’t apply to individuals who gamble for real money. In all 50 states, if you play real money online slots in the privacy of your own home, you won’t be fined or prosecuted.

What is the legal gambling age in the US?

In many land-based casinos, the legal gambling age is 21. Because most brick-and-mortar casinos have alcohol sales, anyone who comes through the front door needs to be of drinking age. Thus, the legal gambling age is 21 for those who play in licensed online gambling states. If you play online at an offshore online casino, then the legal gambling age is 18.

What is the best online slot site?

Because different players have different gaming needs and wants, no single answer exists. Thus, read through our table of the best online slot sites and pick the one which best fits your preferences. In the article above, we have a table with seven excellent online casinos. Certainly, each fits our standards of a great online slot casino, and each has hundreds of slot games.
