We want our readers to enjoy a quality playing experience and the best games to choose from, without having to spend hours on the research.
Take a look at our detailed selection process and see how we ensure we only recommend the best slots casino sites to our readers.
-
Online slots library
We look for US online casinos partnered with the best gaming providers, such as NetEnt, Big Time Gaming, IGT, Konami and NextGen. This ensures a quality slots selection with hundreds of titles to choose from. These providers are known to offer excellent payout rates, the best graphics, variety in themes and frequent new releases.
-
Game filters & user experience
Most casinos have hundreds or thousands of real money slots. This is why we prioritize slots casino sites that have good sorting filters. You should be able to filter slots by category, payout rate, “Hot and Cold”, features, themes, and so forth.
-
Average payout rates (RTP)
The best gaming providers have good overall payout rates. However, many online casinos only feature a small selection of a provider’s slot library. We analyze the average RTP to ensure satisfactory payout rates across the board.
-
Secure and fast payments
Casinos are not all about slots. One of the most important elements is access to convenient payment methods and fast withdrawals. Online casinos that accept PayPal and fast bank transfers are an obvious choice.

Slots bonus offers
As bonuses play an important part in your online slot machine experience, we analyze the different ongoing bonuses offered by casinos. We make sure to feature casinos that offer frequent slots bonuses. Some sites also offer free spins welcome bonuses, but they’re not very common.
-
Quick live support
The key aspect of having smooth slot game sessions is fast access to live chat support. We test a casino’s availability, response times and knowledge. This way, you know you’ll be in safe hands if something goes wrong or you need help with something.

Not Recommended Slot Casinos
There are many casinos advertised to US players, but not all of them have a license. In fact, some of these sites have a troubled history, even though they’re fairly popular.

Make sure to use your judgment when choosing casinos you find online. Look for the casino’s license information for the state you wish to play in, such as NJ, Michigan or Pennsylvania.
Types of Online Slots
Based on the layout of the slot game, the mechanics, and the size of the prizes, there are several different types of slots. The categorization of slots is subject to different interpretations. In general, there are three different types:
The type of the slot game itself is irrelevant unless your criteria cover the specific details that we differentiate between them, such as the slot jackpot, their layout, or the mechanics of said slot game. These are the three groups of slots that are available at US online casinos.
Other Types of Slots
Classic slots have 3-reels and are also known as “fruit machines” as they usually feature fruit symbols on their paylines. These games are known for simple gameplay, basic features, and vintage graphics. You’ll usually only a couple classic slots in an online casino, since they are becoming extinct.
In contrast, a brand new slot type is the live slot. Live slots combine live dealer casinos and online slots. The game plays out normally, but in a lively environment alongside other players.
Real Money Slots vs Free Slots
Playing for free is available anywhere, and you can play almost any game, excluding live dealers. Let’s see what are the benefits and disadvantages of both.
- Great entertainment value
- High winning potential
- Can claim casino bonuses
- Risking real cash
- Test games without risk
- Free at any US online casino
- Can get dull quickly
- Can't win real money
It goes without saying that the differences between playing real money slots and ones for free is huge. We recommend testing the game’s features, learning the game’s rules, getting familiar with the payout table in free-to-play mode. It’s also worth noting that the free-to-play hit rate and RTP are not indicative of the real, legal, tested RTP displayed in the terms and conditions.
Online Slot Game Providers
Learn more about the faces behind the best games in the industry. These slot providers are currently among the most popular in the industry. They create the best, most rewarding slots out there.
Provider | Number of slots |
---|---|
NetEnt | 110+ |
IGT | 90+ |
High 5 Games | 170+ |
Big Time Gaming | 20+ |
Red Tiger | 25+ |
The vast majority of game providers focus on slots, with only a handful of them offering other types of games, such as roulette, blackjack, and baccarat, for instance. This makes online slots the most competitive niche in the online gambling market.
Each game provider has its distinct traits, which makes it very easy to distinguish between them. Because of these, they are known to create loyal fan bases that anticipate slot releases months ahead, waiting for limited period casino promotions to feature them.
Slots Make the Most of Casino Games in the US
While drastically varying in number when compared from state to state, online slots still make the majority of casino games in the US. This is nothing out of the ordinary and just shows how dominant slot games are at casinos on a global scale. US casino players enjoy one of the best slot offer legally available, in the world. There are a few slot game providers still missing that have proven their worth in other markets, such as Canada and Europe.

We recommend playing Megaways slots such as Bonanza or Who Wants To Be A Millionaire Megaways.
How do online casino slots work?
