Free Slots

When you log into any online casino, there's no question that online slots make up a majority of the casino games available. But slot games, in many ways, are like a fine wine. The three-reel classics gain new meaning as technology improves, while today's real money slots continue to push the envelope. While finding and playing slots differs from buying a car, it does take a little know-how and maneuvering to understand.

Our team is battle-tested in video slots, progressive jackpots, and free slot machine games. We also know the sterling online casinos like Caesars Palace Online Casino to win a jackpot or two -- sometimes in the same game with your favorite slot games. But if you're into playing free slots online, consider this free slots guide as your definitive source for the best free slots.

Wishwood

Wishwood is an interactive five-reel real money online slot by IGT. Available for instant play on mobile devices in the seven states that sanction real money games, Wishwood is a slot game where you journey through an enchanted forest. Even though there are only twenty pay lines, there are plenty of bonus features like spin bonus games and the chance to win 10,000x your bet.

88 Fortunes

88 Fortunes is a staple slot machine at retail casinos like the MGM Grand, and it is also available online for real money play at many of our affiliates like Fanatics. 88 Fortunes is one of the top Asian-themed slots with 243 pay lines. It has a free spins bonus round that begins with ten free spins, but when you land enough scatter icons, you can win free spins without a limit. The fu bat jackpot feature comes in different tiers.

Bloodsuckers

The Bloodsuckers series by NetEnt is one of the top slot games at premier sites like BetMGM and Borgata. Following Nintendo's Castlevania theme and Devil May Cry, Bloodsuckers takes place inside a gothic castle home to vampires, bats, and other demonic entities that actually pay well. Available at our esteemed affiliates and best online casinos like PartyCasino, the first Bloodsuckers game features bonus rounds and vampire wild symbols in a coffin. With an exceptionally high 98% RTP, Bloodsuckers continues to rank as one of the top real money slots.

Atomic Meltdown

Depending on whether the online venue offers demo play, Atomic Meltdown by Everi is one of the top free slot games that members can try before playing for real money. ​The Atomic bonus games can happen with any spin, and the Atomic free spins round also boosts the winning multiplier.

Cleopatra

IGT is the game developer behind Cleopatra, one of the most popular slot machines, and it's available at many of my favorite online casinos like FanDuel. FanDuel Casino also has sequels and spin-offs like Cleopatra Gold, which are popular with casino bonuses. Cleopatra has been available since 2005. It's staying power and appeal is about the crisp animated graphics set in ancient Egypt. IGT goes out with the design, featuring Egyptian hieroglyphics and other high-paying Egyptian symbols. The Sphinx leads to the free spins feature, which can be re-triggered with enough scatter symbols falling. Even though Cleopatra doesn't have a progressive jackpot, five Cleopatra symbols on the reels lead to 10,000x your bet.

Rainbow Riches

Rainbow Riches has been around the block since 2006. Barcrest, under Scientific Games, is the developer behind Rainbow Riches, which centers around the Leprechaun. Rainbow Riches is one of the triple profits games with the road to riches, the wishing well, and pots of bold bonuses that lead to instant cash prizes. For mobile slots, Rainbow Riches is normally available on official casino apps.

How to Play Free Slots Online

Because they know members have different budgets, some sites, like my personal favorite online casinos, offer many non-progressive jackpot slots for demo play. By practicing with games like Wheel of Fortune, you can learn what works and what doesn't without financial risk.

If the site supports free play, it will indicate which slot machine qualifies for free play, or there will be a dedicated free slots page. Free slots work like mainstream slot games. All the winning combinations for real money work, but you can't cash out or win cash prizes. Like real money slots, many amazing free slots come with different themes like sports, Asian and Egyptian mythology, science fiction, and more.

Free Online Slots

Usually, progressive jackpot slots and many fixed jackpot slots don't qualify for free-play games. Free slot games allow you to play through a featured called "practice" or "demo." Sometimes, when new online slots come on, there are exclusive casino bonuses like free spins to get members to try them out. After they explore the free online slot, they can't wait to play for real.

Most Popular Free Slot Games

Free casino slots come in different themes and variations. Here is a list of some of the best free slots available today.

• Starburst: Starburst continues to be one of the most popular free US slot games with a demo version. Even though the graphics are simple and it doesn't have any free spin games, Starburst is the subject of many free spin bonuses and a great introduction to new players looking for slots to play.
• Sweet Bonanza: Pragmatic Play is behind Sweet Bonanza, one of the most successful real money slots. Sweet Bonanza is also one of the most popular free slots for online casinos that support free slots play. For a six-reel slot, Sweet Bonanza doesn't have wild symbols. Instead, it has a tumble feature for cascading wins that tease you of incredible wins should you play for real.
• Wheel of Fortune: Not only is Wheel of Fortune one of the most successful slot machines available throughout the country, but it is also available on the free slots market. It takes its cues from the legendary game show of the same name and offers a free play experience on the latest mobile devices.

Themed Slot Games

Real-money slot machines come in different varieties and themes. Asian-themed slots remain among the best-selling and highly-played genres because they usually feature multiple jackpots. Fantasy adventure real money games like Divine Fortune are also high-performing options at major league iGaming sites like BetMGM.

Popular Slots: Themed Variants

As we mentioned earlier, Asian-themed slots are so abundant that many casino bonuses rotate around them, especially for Chinese New Year. Besides 88 Fortunes, here are some of the leading Asian-themed slots available for real money play or a chance to play for free.

• Fortune Coin: IGT is behind Fortune Coin, a 243-payline game with four jackpots, including the max one. If you play online slots, you'll surely appreciate the different coins and how they help you win multipliers as high as 20x.
• Jungle Jim and the Lost Sphinx: The Lost Sphinx is part of the Jungle Jim series. It also capitalizes on the Egyptian-themed flurry of slots led by Cleopatra and Book of Dead by Play'n Go. Jungle Jim and the Lost Sphinx takes you inside ancient Egyptian culture, including mummies, tombs, and a superb 96.3% RTP.
• Buffalo: For those who enjoy American pioneer life, Buffalo is a slot machine working to build up the growing American frontier slot game theme. While the RTP is less desirable at 94.85%, Buffalo is normally available for playing free online slots for sites that support them. Buffalo makes up for its lack of bonus features with the chance to trigger the extra reel to play with 1,024 pay lines.

Best RTP Slots

If you're new to slot machines, the best slots are the ones with at least a 95% RTP. RTP is short for return to player, which measures casino game profitability. You gauge RTP for casino games based on a $100 wager. So, if the RTP is 95%, you can expect a $95 return from those casino games. After you play free slots and free casino games and want to play for cash prizes, these particular slot machines have more than favorable RTPs.

• Jumanji: Jumanji is one of many video slots based on Hollywood movies. While you won't find the main film characters in this slot game, you will find the chance to get the reels spinning for as small as a dime. Jumanji also has a high 96.33% RTP, so if you have $100 to spend, you can expect roughly $96.33 back. Notably, Jumanji is a slot machine with sticky vine symbols that remain in place during re-spins.
• Divine Fortune: Without a doubt, if you frequently play online slots, chances are you have played either Wheel of Fortune or NetEnt's Divine Fortune. Divine Fortune is famous for its falling wild bonus round that features the unicorn. It remains a main draw for its several fixed jackpots, Greek Mythology theme, and a renewable free spins bonus round. Divine Fortune's RTP is 96.59%.
• Gorilla Kingdom: Gorilla Kingdom is a pioneer for the sensational modern-day slot machines with a jungle theme. The king of this 1,024-pay line game is the ape. Gorilla Kingdom has a 96% RTP and generous bonus rounds like the free spins bonus round, where you can begin playing with twenty free games. Multiple gorillas on the pay line lead to transforming symbols into higher-paying ones.

Overall, the first Bloodsuckers game has one of the highest RTP percentages at 98%. Bloodsuckers II features a slightly lower 96.4%, but it is worthwhile with bonus rounds like the bound pick feature and the free spins feature.

Most Popular Virtual Games

If you don't mind playing a free online slot, aren't overly concerned with online slots with high RTP percentages, or winning a progressive jackpot like Wheel of Fortune, you have many super popular video slots available 24/7 at the best online casinos.

• Da Vinci Diamonds: Da Vinci Diamonds is one of IGT's most successful video slots. Depending on the site, you might be able to play for free. Da Vinci Diamonds' RTP varies depending on the casino, but it is one of the few online slots with a Renaissance theme. In the free spins bonus round, you get to admire many of Da Vinci's words of art, such as the Mona Lisa. This online slot machine also has a tumbling reel feature to boost your wins.
• Gonzo's Quest: Even with the flurry of new online slots, the original Gonzo's Quest remains one of the most played online slot games at my favorite online casinos. Gonzo's Quest revolutionized video slots with the avalanche feature, otherwise known as the megaways.
• Mega Moolah: If you want to play slots with an edge, look no further than Mega Moolah. Mega Moolah's jackpot routinely hits over a million. Because of the progressive feature, chances are you won't be able to play for free.
• Book of Dead: Book of Dead is one of the online slots that helped  make Egyptian online slots more mainstream. The gameplay takes place inside the Pharaoh's tomb, with the magic book serving as the scatter and wild symbols. The highlight is the random symbol morph.
• Book of Ra: Book of Ra is one of the most visually stunning video slots available today. It honors the Egyptian sun god Ra, who hands out on the reels and is one of the main characters and highest-paying symbols in the game. The magical Book of Ra icon is the scatter and wild symbol that opens up the free spins bonus.

Different Ways to Play Free Online Slot Games

Lost in the shuffle and in the discussion of free online slots are vintage three-reel games. Online casino members can play many single-reel games with fruits and bar symbols for free. Also, many of today's modern free online slots come in five-reels. Let's help you get up to speed about the different ways to play free slots.

Mobile Slots

Because Microgaming helped lead the mobile gaming charge before mobile play took off, many of their titles are available to play for free. With the ability to play free slots anywhere in your legal state zone, many players look to download the official apps so they can play away from home. Sometimes, Caesars Palace Online offers exclusive mobile promotions to encourage free play.

Offline Slots

In the early days of flash casinos, members could download the casino software on their computers and other devices. While the game variety isn't as extensive as playing online, the benefit is not having an internet connection to enjoy them. Today, the official casino apps let you play offline, and sometimes, the chance to play free slots if the site has demo play.

Progressive Slots

Progressive slots can work locally or on a network. The concept behind them is that the sum of all the wagers goes into the progressive pot, where one lucky winner collects it all. It's common for progressive slots to go into seven figures. However, free slots usually come with something other than progressive titles.

Themed Slots

Whether there are three, five, or six-reels like in Gates of Olympus, besides the stunning design and bonus features, slot games come in different themes. Running the gambit from sports to fantasy to mythology, slot players can usually find a free slot game or a real money one that meets their preferences.

Vegas Style

The best online casinos strive to offer variety, and one of the best attractions is Vegas-style slot machines. These are the classic single-pay-line wonders that were the rage decades ago, including the Wheel of Fortune. ​

Free Spin Games

Most video slots contain a free spins feature, which is a bonus in the game where you get to win money for free for a certain number of spins. Unlike free slots, you can win money with this feature, but you must make a deposit to trigger it.

Free Slots Online vs Real Money Slot Games

Pros for free games can include no risk for beginners, easy-to-follow RTPs, and pay lines. Pros for real-money slot games can consist of a wider variety of games, added excitement, and more available casino bonus options.

If you plan on winning actual cash prizes, you'll have to make a wager. The exception to that rule is through no deposit bonuses or free spin promotions that are eligible for certain games. Free slots have all the slot features, but you can't cash out.

Real Money Pros:

1. Can win instant cash prizes

2. You can win a major prize any time a progressive jackpot or other fixed jackpots hit

3. Can rack up on other bonus features like re-spins and mega ways

Real Money Cons:

1. Players must spend actual money

2. No guarantee of winning

3. Some minimum wagers might be expensive

Free Slots Pros:

1. No money is required to play

2. Can have fun without financial stress

3. Can learn about the game and try to build a strategy

Free Slots Cons:

1. You can't walk away with cash

2. Might be limited with the game options

3. These games are not eligible for promotions and bonuses

US States with Legal Online Casinos

Today, seven states sanction online casino play, with more states like New York, Georgia, Illinois, and Alabama pushing hard to join them. If you live in one of the states below, welcome to the club when it comes to elite slot gameplay.

Michigan

The Great Lakes State legalized online gambling in 2019 when current Governor Gretchen Whitmer signed legislation for online sports betting and online gambling. Today, Michigan operates sixteen online casinos, including many of our affiliates, like Fanatics and Golden Nugget. The Great Lakes State closed out 2023 just shy of $2 billion in online gambling revenue.

New Jersey

New Jersey became the second state behind Delaware to regulate iGaming sites in 2013. The Garden State is home to the most online casino operators, with more slated to open. Besides the heavyweights like BetMGM and Borgata, New Jersey has online sites from land-based casinos like Ocean Casino.

Pennsylvania

The Keystone State authorized legal online gambling in 2017 after Governor Wolf signed HB 271 into law. However, it wasn't until two years later that PokerStars became the first iGaming site to launch, behind the wild success of online poker. Pennsylvania's online casinos continue to flourish, with over $233 million in March of this year. Despite Unibet pulling out of the North American market, the Keystone State still generates the most gambling tax revenue behind Nevada.

West Virginia

Even though it is one of the smallest states in the country, West Virginia is a powerhouse when it comes to online gambling. West Virginia has been regulating iGaming and sports betting in 2019, becoming the fourth state to do so.

Connecticut

Governor Lamont signed passage to bring online gambling to Connecticut in 2021. However, only two online sites currently operate, Mohegan Sun and DraftKings. This past March, Connecticut online gamblers produced over $40 million in revenue.

Delaware

In 2012, the no-sales-tax state made history by becoming the first in the nation to regulate online gambling. Delaware also was one of the first states to legalize sports betting.

Rhode Island

Rhode Island launched online gambling operations in early 2024. Bally's currently operates online, with plans for more iGaming sites to enter Little Rhody.

Can I Play Free Slot Games and Get Payouts?

The iGaming site or mobile app must first support free slot play. DraftKings is one such site that does. Sometimes, you come across a free spins bonus or a cashback bonus that can be used to play free online slots and cashouts. New members who get deposit bonus money can use that money to play free slots. Some of our high-profile iGaming affiliates might offer exclusive mobile promotions that can be used to play free virtual slots.

Either way, the first step is to create your account either on the website or on the app after you download it. You can always rely on our in-depth reviews from our standout and reputable iGaming partners to help you make your choice. When you know your choice, head to the official website and follow these straightforward instructions.

1. Once on the site, locate the "Register" or "Join" link. Click it to start the download.

2. Once the registration form loads, please enter your full legal name, a valid residential address, a phone number, and email address for verification. You must also submit your birthday for eligibility reasons and the last four digits of your social security number. A robust username and password that doesn't contain your name or email address is also required.

3. Before pressing send, review the site's official terms and rules. Each member must abide by these rules to maintain their accounts.

4. Check the agree to terms box and press send when ready.

5. Look out for a verification email link. Click it to finalize your account.

6. Sometimes, you might have to upload photo identification to compare your address and social security number. Please follow these steps and only submit valid identification. Most online casinos use AI and multi-factor authentication to help weed out fakes and fraud.

If all goes well and your account is up, feel free to make a deposit to trigger the splendid new member welcome package.

Find your Favorite Free Slots

Suppose you've ever wondered who the brains and genius behind many of your free slots and other blockbuster slot machines are. In that case, I've put together a short list of some of the most outstanding slot developers that our unparalleled iGaming partners rely on. These developers believe in fair play and use random number generators in their slot masterpieces. Our esteemed iGaming partners are more than happy to be audited by gaming divisions like the Pennsylvania Gaming Control Board for total player satisfaction.

Konami

If the name Konami sounds familiar and you grew up playing Nintendo in the 80s, you're not seeing things. Specifically, the Konami Gaming division focuses on slots and has been doing so since the early 2000s. Konami is behind many artful and Asian-themed slots like Ancient Dragon and Lion Festival. However, they do develop more diverse slots, including African-themed ones like African Diamond. Most Konami slots feature unique icons that only appear in bonus rounds and special reels during bonuses.

IGT

IGT, International Game Technology, dates back to 1975. Staying in tune with the evolution of iGaming, IGT is behind innovative five-reel titles with bonuses like Da Vinci's Diamonds and Double Diamond. International Game Technology is also a major player behind multi-way slots that pay in all directions and Hold and Win titles.

WMS

WMS has been producing groundbreaking slot machines and virtual free slot machines for years and as iGaming evolved and took off. You might already be familiar with many of their mainstream titles, like the Zeus series of slots, and standout titles like Wizard of Oz and Jackpot Party. WMS also puts a twist on winning combinations by featuring animated reels and charged-up re-spins.

Novomatic

Even though Novomatic is based in Austria, they have successfully invaded the American slot world with fan favorites like Book of Ra, an interactive Egyptian-themed slot, and Lady's Lucky Charm. As an added feature, many of Novomatic's slots work like a charm, pun intended, on the latest generation of mobile apps.

Red Tiger

If you prefer diverse slot themes with mind-boggling realistic graphics, Red Tiger is near the top of the list of developers for video slots. Many Red Tiger video slots are part of the Daily Jackpot sections you can find at FanDuel and other leading iGaming sites. Also, many of those Red Tiger titles offer hourly jackpot wins as an extra incentive.

Why Play Free Slot Games Online?

Slots, like other games, are games of chance, even though a random number generator is used to determine random results. In other words, you're not always going to win, even if you're playing video slots with a minimum 95% RTP. However, playing free slots lets you preview the games and all the features without risking a cent.

After playing for free, you might decide that that particular slot isn't your cup of tea, and you can save your bankroll for other video slots. And for an even simpler reason, you can just have some fun with the game to relax without overthinking. For mobile app players, the ability to pick up and go with free virtual slots can lead to a more lucrative relationship and partnership with the iGaming site.
