While real money online casinos are only legal in a few U.S. states like New Jersey, Pennsylvania, and Michigan, we also feature Social and Sweepstakes slot websites that are accessible across most of the country. These sites operate under U.S. sweepstakes and promotional rules, which makes them available to players in areas where traditional gambling websites aren’t allowed.
Social casinos are just for entertainment, offering virtual coins that don’t carry any cash value. Sweepstakes casinos, however, give players the chance to collect “sweeps coins,” which can be exchanged for real cash or prizes. We promote both options because they offer fun, legal ways to play online slots for a wide U.S. audience. Want to learn more? Visit our full guides on social casinos and sweepstakes casinos.
Here you can find all online slots reviewed and tested for US players. We have collected detailed data, including RTP, themes, features, and more!
Visit any of our best-rated slot sites in the US, and you’ll likely find plenty of top-quality titles, some of which will be very familiar. Most sites also have a section listing player favorites. This is where you’ll typically find Gonzo’s Quest, Starburst, and Mega Moolah, among others.
When reviewing real money online slots, our experts examined all the factors that influence gameplay, such as the theme, bonus features, RTP, volatility, overall entertainment value, and profitability. After many enjoyable hours playing these games, we’ve compiled a list of the best online slots in the USA for your convenience.
Developed by IGT, Cleopatra is a famous classic slot. It features a 5×3 grid with 20 adjustable paylines and a minimum bet of $0.20 if you’re using all paylines.
The Egyptian theme also extends to the symbols, with stylized low-paying Ks and 10s. Meanwhile, the game’s logo is the highest-paying symbol, which pays out $10,000 for five of them. It also acts as a wild, so you can easily form winning combinations.
Meanwhile, the Sphinx is a scatter symbol, so getting at least three anywhere on the reels activates 15 free spins. The feature can be re-triggered during the spins, and all wins are tripled, except for the maximum prize.
AGS is another developer with many classic slot games, such as Riches of the Nile. It is an Egyptian-themed slot suitable for players of all budgets, with its minimum bet of $0.75.
During the game, you collect orbs, which can activate various features. For example, two orbs transform the reel into a wild one, where some symbols get upgraded into wilds. You only need one orb for a wild reel during free spins. As for the free spins, you can get up to ten by landing five scatter symbols.
When getting an orb, it will launch a ray into the sky for the chance to trigger additional prizes. You can get a cash prize of up to $2,500 or trigger one of the four fixed jackpots. Note that orbs do not transfer from the base game to the free spins version.
Playtech’s Better Wilds is a stylish slot suitable for all players. Its bet limits range from $0.05 to $2,500, so you can find a comfortable range.
True to its name, the game is focused on wild symbols. The regular and special wilds pay up to 500x your bet, so you can expect decent prizes. While regular wilds can appear anywhere, special ones only show up on reels 3, 4 and 5.
While they have similar payouts, the Special Wilds have a bonus feature. After getting at least one, you will activate respins, where the wild moves across the board. It will expand to cover the reels if it moves more than once. That continues until the wild leaves, but additional ones re-trigger the feature.
88 Fortunes is a popular Chinese-themed slot from Bally with a great jackpot feature. The game has a 5×3 grid with 243 ways to pay, with the high volatility making it suitable for high-rollers.
While the minimum bet is $0.08, it can increase up to $0.88 if you play with all five gold symbols. These symbols will also increase the payout and allow you to access the jackpot feature. Getting one or more Fu Bat symbols awards a jackpot, with a special minigame if you’re eligible for more than one prize.
Getting three or more gongs activates up to 10 free spins. All low-paying symbols are removed during the bonus, and the Fu Bat remains, so you can still activate the jackpot. Additionally, you can re-trigger the spins by getting more symbols.
NetEnt’s Divine Fortune is one of the most popular progressive jackpot slots. Despite its high volatility, its minimum bet limit of $0.20 allows even low rollers to try it. The Greek mythology theme and animated symbols are great for those seeking added entertainment.
During the base game, you can land Falling Wilds, which trigger respins and slowly move down the reels until they disappear. If two wilds appear on top of each other, they will expand to cover the reel. Getting at least three free spins symbols also triggers up to 12 free spins, where every wild expands.
Getting at least three bonus symbols, activates the jackpot minigame. You will get three spins, where the grid is slowly filled with bonus symbols. You win the progressive jackpot prize if all three rows are filled in.
With tons of options, which slot providers actually deliver? We have tested over 30 to find out!
IGT and NetEnt are our top recommendations. With them, you get some of the most popular and recognisable online slots in the world. Their new online slots are usually very fun, and pioneer engaging new features such as cascading reels, cluster pays and split symbols.
Still, remember that you should only play games with providers licensed for your state. In this way you can ensure that the games are legit and pay out.
Games developers are always creating different ways for players to enjoy playing slots online. From simple and classic three-reel designs, through to five-reel slots that have more complex gameplay features, with each offering unique styles of play to keep you entertained.
| Three-reel slots | Best for new players |
| Five-reel slots | Suitable for advanced players |
| Progressive jackpot slots | Best for higher payouts |
| Multi-payline slots | Offer a higher chance of winning |
| Branded slots | Have unique audio and visual styles |
Access to different types of slots will mean you can always find something fun. Even if you’re an experienced player who enjoys progressive jackpot slots, you can try out alternatives, including classic spinning reels or slots themed around popular movies. The best slots sites we recommend have plenty of options.
Three-reel slots are the digital versions of the traditional machines found in land-based casinos. These games usually feature a single payline and fewer symbols to match across the three reels, making them perfect for beginners and those seeking nostalgic gameplay. Two of the most popular three-reel online slots are NetEnt’s Triple Diamond and Mega Joker, both offering simple yet enjoyable gameplay.
These slots feature five vertical reels, offering multiple paylines and intricate gameplay. They often include advanced graphics, complex mechanics, and immersive storylines. Some of the most popular picks include cosmic-inspired Starburst by NetEnt and IGT’s Cleopatra, known for their entertaining storylines and bonus features like wild symbols and free spins.
Progressive slots are games where the jackpot increases every time a player bets until someone wins. These jackpots can grow to over a million dollars, offering players the chance for larger prizes. NetEnt’s Divine Fortune is a favorite among players, featuring an Ancient Greece-inspired storyline and 20 paylines. Another popular option is 88 Fortunes by SG Digital, available at most recommended casinos.
These games feature multiple paylines, sometimes reaching up to 117,649, as seen in the Megaways series. Unlike traditional slots with a single payline, they offer various ways to form winning combinations. Popular examples include NetEnt’s Gonzo’s Quest, known for its adventurous theme and cascading reels, and Playtech’s Age of the Gods, which combines mythology elements with numerous paylines and free spins.
Branded slots are inspired by movies, TV shows, music, and other well-known franchises. These games entertain fans with familiar characters, themes, and storylines. Our research shows that players often choose NetEnt’s Narcos, based on the hit TV series, and Playtech’s DC Justice League, featuring superheroes like Batman and Superman.
Many more options are available beyond the top five most popular slot types. These include themed slots, fruit machines, 3D slots, and Megaways slots, to mention a few. It all depends on which types of slots you most enjoy playing.
When choosing a slot, it’s important to consider factors like RTP (return to player) rate, volatility, and themes. RTP indicates the potential payout over time, while volatility measures the risk level of the game. Themes add another layer of entertainment, allowing you to choose games that match your interests.
The choice of themes across the best online slots sites can be overwhelming, so if you don’t know where to start, here’s an idea. Some of the most appreciated storylines are adventurous, with Gonzo’s Quest being the perfect example. Ancient cultures, such as Egyptian, Aztec, Greek, and Norse Mythology, are also popular.
Once you pick the best casino for online slots, you can start browsing for new games. Some sites offer additional search filters, which help you categorize the games by title, type, or games developer.
Slot payouts refer to the percentage of initial bets a slot machine returns to you over time, known as the RTP (return to player). Volatility, on the other hand, indicates a slot’s risk level, determining how often and how much it pays out. In the broader context of casino game payouts, slots differ significantly. Table games like blackjack or roulette have relatively stable payouts and lower volatility.
Slots, however, vary widely in both payouts and volatility. High-volatility slots might pay out larger sums less frequently, while low-volatility slots offer smaller, more frequent wins. Good payouts for slots are above 96.00%, so keep that in mind when you want to try a new game. Even though that’s an important factor, remember that outcomes are based on chance and play responsibly.
The return-to-player rate is the approximative percentage of wagered money a slot machine returns to you over the long run. It’s calculated based on millions of spins. An important detail is that RTPs are set by the slots games developers, not the casino. Top providers like NetEnt, IGT, and Playtech are known for offering slots with some of the highest payouts, which we listed below.
RTPs indicate the potential returns over time, helping you pick games with better odds. However, although an important factor, you should rely on more than just the payout rate for choosing. A good strategy is to consider the volatility and match it to your playing style. Features like free spins, multipliers, and scatters could also increase your winning chances. Experienced players know that games with such mechanics are available at the highest payout online casinos, with RTPs over 97.00%.
Payout volatility refers to the risk level associated with a slot machine’s payouts. Low-volatility slots pay out smaller, more frequent wins, while medium-volatility slots offer a balance between frequent payouts and the chance for larger wins. High-volatility slots, on the other hand, provide the potential for bigger wins but with less frequency, appealing to players who enjoy higher risks.
Before you deposit, double-check that the online slots website is legal. Our expert researchers found many available payment methods at the best online slots sites, such as debit cards and e-wallets. We prefer online casinos that accept Mastercard because all deposits are safe and processed instantly.
Another popular choice is playing at PayPal casinos, as this payment method doesn’t require sharing your banking data with third parties. Prepaid cards and traditional online banking are also available, while bank wire transfers are ideal for larger deposits. Our team also suggest avoiding cryptocurrency, as legal online casinos don’t offer this method, so it’s a red flag if you see a site that does.
While deposits are possible with various payment methods, some options, like PayNearMe and PaysafeCard, are unavailable for withdrawals. If you deposit with prepaid cards, you’ll need to choose a different cashout option, such as e-wallets.
PayPal and Venmo provide the fastest casino payouts, with transfers typically taking up to 3 business days. To speed up the process, verify your account with customer support by providing a copy of your ID or other proof of identity.
To legally offer online slot machines, all sites need a valid license for the states where they operate. The only exception to this rule are the leading California casino sites, which operate on a social gambling basis. You should easily find a casino’s permit displayed on its homepage, and we highly recommend avoiding sites with unavailable licensing information. The current state regulators in the US are as follows:
The gambling sites we recommend have the required licenses, and you can always consult the regulator’s site, which shows the full list of registered online casinos. The best slot sites comply with local gambling regulations, providing responsible gambling tools and secure payments. Their websites and apps use data encryption to protect your personal and financial data, while the state authorities regularly audit games.
Playing online slots is straightforward and fun. To get started, choose the best casino for online slots and open an account. Then, select a game, set your bet amount, and hit the spin button. The goal is to match symbols, usually at least three, across the reels and paylines to win prizes. Reels are the vertical columns that spin, and paylines are the lines that determine winning combinations.
The number of paylines varies from one to hundreds. The more paylines, the better the chances for landing matching symbols. Some games also have bonus features like free spins, multipliers, wild symbols, and mini-games, providing additional ways to win and keep you entertained.
Online slots use a random number generator (RNG) to guarantee fair results. Many casinos offer free demos, allowing you to try games before spending any money.
Online slots come with various themes and elements, each representing different values. Basic symbols typically offer lower payouts, while higher-value symbols or special characters provide bigger rewards when they form winning combinations. You can always find information about matches, payouts, and features in the game rules.
Players often seek games with more than just standard reels. Special symbols like wilds can substitute for others to complete winning combinations. Scatters trigger bonus features like free spins or special mini-games, regardless of their position on the reels. Multipliers increase the payout of any winning combination they are part of, making them highly valued.
It will substitute for most symbols – bar scatters – to complete winning combinations on the reels.
Land three scatter symbols anywhere – not only on a payline – to trigger a cash prize or bonus feature.
They multiply a win by a set amount – a 2x wild, for example, doubles your payout. A multiplier can go up to 15x, which is very satisfying.
The best online slots also feature unique symbols with special functions. These can include expanding wilds that cover entire reels or sticky symbols that stay in place for several spins. Such features, combined with a good RTP rate, don’t guarantee a win but can increase your chances of landing winning combinations.
You can play online slots on licensed and regulated casinos. Some of the best slot sites own permits from the NJ Division of Gaming Enforcement, Michigan Gaming Control Board, Pennsylvania Gaming Control Board, and the WV Lottery Commission. The casinos we recommended here are legal, offering real money slots from top games developers like NetEnt and IGT.
Choosing the best game depends on what kinds of slots you like to play. However, if you're a beginner, you can start with the three-reel online slots like Mega Joker. If you're ready to level up, check NetEnt's five-reel Starburst or Gonzo's Quest, one of the most popular adventurous slots with multiple paylines.
Some of the highest RTP slots have payouts of over 97.00%. Mega Joker's return-to-player rates go up to 99.00%, and we recommend it for the progressive jackpot included. Monopoly Big Event has the same payouts but betting limits up to $500, making it suitable for high rollers.
You don't have to worry if you play at online casinos that meet licensing and safety standards. Online slots are based on RNG mechanics, which are regularly tested and audited by third parties, such as independent agencies or state regulatory bodies.
Yes, you can choose from real money vs free slots. Some of the suggested slot sites offer demo versions, so you can try a game before depositing. Another option is to play at social casinos that use virtual currency instead of real money.
Online casinos with slots give you a wealth of top-quality options if you want to spin the reels. We’ve reviewed many sites to provide a complete list and found there was always something new to explore, including innovative features and interesting themes.
Keep in mind that all the best online slots casinos we feature are entirely legal, so you can gamble without worrying about getting scammed. They also offer a fair bonus, a fantastic range of slot variations, and a great selection of other games. Now, all you’ve got to do is pick your favorite.
Tip: When choosing online casino slots to play, don’t forget to check the game information pages with the paytable before spinning the reels. You’ll find game rules, winning combinations, plus details covering any special features or bonus rounds you can trigger while playing.
