Popular Slots in the US

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 have a section of the game’s library for 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. Know that at most of them you can play blackjack online as well.

Cleopatra (IGT) – 95.13% RTP

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.

Riches of the Nile (AGS) – 94.12% RTP

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.

Better Wilds (Playtech) – 96.42% RTP

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 (Bally) – 96.00% RTP

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.

Divine Fortune (NetEnt) – 96.59% RTP

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 an immersive experience.

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.

Ranking the Best Online Slots Casinos

We take numerous factors into account when ranking the top slots websites. A game’s payout is essential, but other elements we consider are the graphics and layout of the game. Security and fairness also rank highly, as do the available payment methods and the size and regularity of any bonuses.

Every player is unique, and some factors might be more important than others. Most of the best online slots casinos offer various perks for their customers, but we’ve picked those that excel across the board, including online casinos with top payout.

Along with meeting our strict standards regarding the factors mentioned above, our top-rated slot sites also allow you to enjoy all their games on the go using well-designed and straightforward mobile apps.

Licensing

Before you deposit any funds with online casinos with slots, check if your chosen casino is licensed for the state where you’re located. Casino platforms are licensed and regulated by local government gaming authorities.[1]

For example, in New Jersey, the responsibility for ensuring online casinos operate fairly falls to the New Jersey Division of Gaming Enforcement.

We perform all the necessary checks to ensure all the best online slot websites we feature hold the required licenses and are safe to play on. But, if you want to investigate yourself, there are some things you can do. Look for a logo in the footer of the operator’s website. Alternatively, you can check the relevant regulator’s site for a complete list of registered online casinos.

Bonuses

All the top online slot sites in the US offer a selection of bonuses for new and existing customers. Before making any recommendations, we look at various aspects of each bonus, particularly the terms and conditions and wagering requirements. If you want the best casino bonuses in the US, you should also pay attention to the validity, minimum deposit, and other restrictions.

RTP (Return-to-player)

A slot’s RTP rate indicates how much of the funds players spent will be theoretically returned as prizes in the long run. It is calculated across multiple rounds, showing the average payout, not the chance for short-term wins. Most slots have around 96%, although some, like Bloodsuckers, can reach 98%. Games with lower percentages typically have jackpot features, so we recommend browsing them carefully.

Volatility

Volatility fulfills a similar role to RTP, but is used to gauge short-term chances of winning. Low volatility slots can provide smaller prizes, but they appear frequently. Meanwhile, high volatility slots have bigger ones, but you have lower chances of getting them. Once again, jackpot slots typically have higher volatility, so they’re more suitable for experienced players.

Apps

If you want to play your favorite slots on the go, a user-friendly app is available at most of the best online slots casinos. Recent statistics show that you love playing on your mobile devices[3] as much as we do, so we ensure they’re suitable for Android and iOS devices. Other factors we consider before adding it to our list of top online casino apps include the extent of the mobile games library, seamless operation, and excellent design.

Software Developers

Without a selection of software developers, the best casino slot websites would struggle to fill their game libraries. It’s very competitive in the world of online casino game development[4] , but several providers stand out for their slots games. Here are our top five favorites:

  1. IGT – TV and movie-themed slots
  2. NetEnt – Innovative avalanche feature and colossal symbols
  3. Light & Wonder – Top favorite is Rainbow Riches
  4. Play`n GO – Rich narratives and compelling characters
  5. Playtech – Exceptional graphics and high payout rates

You’ll find games from these software developers at all the best casino slot websites. There will be an option to play them using a desktop or mobile device, whichever you prefer. These top five software providers stand out to us because they create the highest quality games, featuring plenty of innovative features, crisp graphics, and memorable soundtracks.

Game Variety

Slot games are one of the most varied casino game types. Aside from classics such as Starburst, the top online slot sites have many progressive jackpots or old-school steppers like IGT’s Double Diamond. Some sites even have exclusive titles with unique minigames, animated backgrounds, and storylines.

Payment Methods

All the best real money online casinos in the US that we feature accept various payment methods, including debit and credit cards, eWallets, and prepaid cards. Bank transfers are an alternative option, plus Cash at Cage and cash at retail locations.

  • Visa
  • Mastercard
  • Discover
  • American Express
  • PayPal
  • Skrill
  • Apple Pay
  • paysafecard
  • PayNearMe
  • Play+
  • Bank Wire Transfer
  • Online Banking
  • VIP Preferred
  • Cash at Cage
  • Cash at Retail Store
  • Venmo

Online casinos with slots prefer it if you withdraw using the same payment method you used for making deposits. However, not all the payment methods mentioned can also be used for making withdrawals. Prepaid cards, for example, tend not to be accepted when requesting a payout.

Types of Online Slots

Slots have been around since the 19th century, so you can expect a decent variety when you play slots for real money. Most games tend to be classic 5-reel slots, although some have expanding reels or 3D visuals. Experienced players also often look for slots with interactive minigames or jackpot prizes. Here are a few of the most popular types:

Free vs. Real Money Slots

You can play a wide variety of slots for real money at the best online slots casinos and some of the best social casinos as well. It might seem like the experience is the same, but it’s remarkably different.[5]

However, many of the best online slot casinos also feature demo modes. That allows you to test the games and play with high limits without worrying about your budget. It can also be useful for trying some of the bonus features and checking the game’s volatility.
