Most Popular Slot Sites in the US 2022

Before you start playing slots online, it’s a good idea to learn more about how they work and where to find the best online slot casinos in the US. There are thousands of slot games available to play online and it’s important to know how they work, why they’re so popular and how to choose the best games. Find out all the details in our guide below.

What Are Online Slots?

Online slots are the online version of slot machines, where players select their bet and pull a lever to spin the reels. The first slot machine was created in 1891 and these early machines were all mechanical. Over the years, they’ve changed a lot, and modern machines are now powered by a computer. Online slots are similar, with a computer program that determines the outcome each time you press the spin button.

When you play slots online, you select your stake before hitting the button to spin the reels. By landing certain symbols on the reels, players can win a payout based on their bet and the symbols that appear. Slots are simple to play and use random chance to determine the outcome of each spin, meaning there’s no way to influence the result of the game.

Compared to a lot of other casino games, they’re incredibly easy to play, which makes them very popular. Not only that, but they offer the biggest payouts of any game and can be played for very low stakes.


How We Rate the Best Casinos for Online Slots

Before you start playing slots, it’s important to make sure you sign up to one of the best online casinos possible. Top casinos will offer a better selection of games as well as great bonuses and rewards. You should also make sure that the casino you join is safe and trustworthy. When we review online casinos, we look at the following factors:


Licence and Security

The license shows that a site is safe and reputable, as it has to follow strict regulations to be licensed. When we review online slot casinos, we take a look at what license the site has and its overall reputation for safety. This includes looking at player reviews, making sure the casino uses encryption, and keeps your data secure.

When playing slots online, you want to have peace of mind that the games you’re playing are fair and that your money is safe. Looking at the license is the easiest way to check this and will help ensure that you can fully enjoy playing without having to worry.


Bonus and Promotions

Bonuses and promotions are always exciting, and when you sign up to a new casino, the welcome offer is often the biggest attraction. When we review top US online casinos, we check out the bonuses on offer, including how much is available and the terms and conditions. We make sure that these offers are fair, fun, and simple to unlock.

Free spins are one of the most common bonus offers you’ll find available for online slots. They’re normally easy to claim and let you test out the most popular slots for free. When we review an online casino, we test out these offers for ourselves to ensure they’re fun and provide good value.


Payment Methods

If you’re playing online for real money, you need to be able to make fast and simple deposits and withdrawals. All of our reviews look at the accepted payment methods and how easy it is to add funds to your account. We check minimum and maximum payments and check how long it takes for withdrawals to be processed.

Payments should always be as straightforward as possible. The best online casinos accept a wide range of popular payment methods for deposits and withdrawals. In addition, there shouldn’t be any hidden charges or fees for you to worry about.


Game Selection

The game selection can make or break an online casino, with the best sites offering a big variety of high-quality games. We go through the games library and take a look at the total number of games available and the different styles and types on offer. Our reviews also check the software providers and make sure that all of the slots available are top quality and compatible with mobile devices.

Real Money Online Slots Licensing and Compliance

When you play online slots for real money, it’s important to know that the games you’re playing are fair and the casino you use is safe. Before you jump into depositing your cash and spinning the reels, make sure you check that your casino is properly licensed. An online casino license allows the site to legally offer games to players from certain areas. In the US, each site must be licensed by the state regulators for each state it operates in.

When a casino is licensed, it means it’s following regulations to ensure fairness and player safety. All games are tested to be fair, and you can rest assured that your funds will be safe. You can also check the return to player (RTP) rate of slots before you play. This gives you a theoretical percentage return for the game, showing you how much you could win back when playing for a long time. The higher the RTP rate, the fairer the game.


Real Money Slots on Mobile

Thanks to modern technology, you can now enjoy slots on your mobile. Playing on a smartphone or tablet has never been easier. All you need to do is visit your favorite online slot casino in your mobile browser and choose your game. Almost all online slots are now compatible with mobile devices, and you can play without needing to download anything.

Some online casinos do offer a mobile app for you to download, but in most cases you can simply play through your mobile browser. All you need is a stable internet connection and you can take your favorite games with you wherever you go.
