What to Look for When Choosing aReal Money Online Slots Casino

There is a growing number of legal online casinos in the United States. But finding a casino that’s right for you can be difficult. That’s why our review team follows strict criteria when rating every online slot operator. Here’s what we look for.

Range of Slots: As US slots players, we want to know that a casino offers a broad range of games. We check to see which providers are offered and whether jackpot slots are included.

Security & Licensing: Real money slots in the US must be properly licensed and secure. We only rate casinos with proper state gaming licenses. Software must be encrypted and games must be independently audited to ensure fairness for every slot player.

Lobby Design & Usability: Navigating your way around thousands of slots can be hard. We test every operator lobby to make sure you can filter games and search by provider or slot theme.

Mobile App: Many Americans now enjoy online slots apps that pay real money. We review the selection of mobile slots and test the download apps for iOS and Android handsets.

Registration Process: How easy is it to sign up for a new account? The registration process at our recommended sites should be quick and simple. ID checks and document verification should be a snap to complete.

Deposits & Withdrawals: Making quick payments is essential if you want to play real money slot games online. We test every casino cashier for speed by depositing our own dollars. We’ll also withdraw cash to test the processing periods.

Customer Support: Got a problem with a slow withdrawal or a slot that has crashed? Good customer support is important for resolving issues quickly. The top US casinos should have 24-hour support via live chat, email or toll-free phone lines.

Bonuses & Promotions: Turn your online slots game play into free cash with a casino bonus. The best online slots in the US offer generous welcome bonuses for new players. You should get a deposit match plus free spins on the most popular video slots.

Why You Should Play Online Slots for Real Money

Legal online slots have only been available in the US for a few years. But there are more reasons to play than ever.

Win real money instantly in your account: Nothing matches the thrill of winning real cash on your PC or mobile. While free-play games are fun for learning the rules, real money slot machines offer the chance of big cash prizes.

Enjoy your favorite land-based slots online: Many of the best land-based slot machines are adapted for online and mobile casinos. Enjoy the same gameplay, graphics and bonus rounds as you would find in your local casino.

Wider range of stakes: Have you been put off by those $5 slots in your local casino? Online slot machines often carry lower minimum stakes. Play for $0.01 a line or hit the max bet and go for the jackpot.

No need to travel to your nearest casino: You can play online slots in a handful of US states. But what if you live hundreds of miles from the casino? Online slot machines provide easy access to real money games.

Earn a better bonus online: Some land-based casinos offer comps to regular customers. But the best casino bonuses can be found online. Sign up and earn a welcome bonus or join a VIP program and earn points while playing slots.

Highest Paying Online Slot Games

Below is a list of the highest paying slot game, based on the game’s RTP. This is the Return to Player percentage, the average payout made to gamblers over millions of spins. It’s a good indication of whether a slots game is generous or not.

Most Popular Online Slot Games in the US Right Now

You can get access to hundreds of legal and tested online slot machines. But which are the best, and which providers should you go for?

There are a handful of regulated software providers supplying games to US casinos. Here, we’ve picked out a top 10 of US online casino slots to get started.

Goblin's Cave

Goblin’s Cave is a classic Playtech slot played with 3 reels and boasting an RTP over 99%. The slot uses a unique slots mechanic which lets you hold symbols on one reel. These are then replicated across every other reel in the game.

Divine Fortune Megaways

Divine Fortune Megaways is a sequel to NetEnt’s popular progressive slot set in ancient Greece. The game features the Megaways mechanic where you can play up to 117,649 ways to win on every spin. Plus, the game boasts a top jackpot worth $1 million.

Fruit Xtreme

Playson’s Fruit Xtreme is a classic slot crammed with fruit symbols like oranges and lemons. The game features multipliers which come into play when you fill the reels with identical symbols.

Understanding the Return to Player Percentage

Every slot is programmed with a return to player percentage (RTP). This relates to the average payouts made back to players over a long period. For instance, an online slot with an RTP of 96% will pay back, on average, 96c for every $1 paid in. The remainder, 4 cents in the dollar, is kept by the casino.

Online casinos normally list their slot RTPs so you can make a judgment on what games to play. In addition, regulated slots are independently tested to ensure their payouts are accurate.

Make Sure to Get the Best Bonus Possible

When you play online slots with real money, you’ll always have the chance to earn free cash. Casinos are always keen to retain players, and they achieve that through various bonuses and promotions. Many people are looking for no deposit slot bonuses. You'll be pleased to know that these slot promotions are readily available at our recommended sites. Other exciting promos that let you play slots for real money include:

Welcome Bonus: Deposit Match

The best way to earn free cash at a casino is by claiming a deposit match bonus. Make your first deposit and play eligible slots in order to clear your bonus. Clear the bonus funds within the set time period and you’ll be rewarded with free cash. Here’s how it works:

• The online casino awards new signups with a 100% welcome bonus up to $500 (for example). That means, if you deposit up to $500, the casino will match it with the same amount in bonus funds.
• All slots contribute 100% toward the bonus. So, for every dollar you play, you will clear a dollar of bonus cash.
• The bonus will carry a wagering requirement. It could be anywhere from 10x to 50x the size of the deposit. To clear the money, you must meet the wagering requirement.
• If you deposited $100 for a 100% bonus with a 25x wagering requirement, you would have to bet $100 x 25 ($2500) on slots before withdrawing your free $100.

Welcome Bonus: Free Spins

As a new signup, you can also claim free spins. It’s a great way to enjoy online slots for real money with no deposit.

In a free spins bonus, you receive a number of free games on selected slots. Play the spins at permitted stakes and rack up some winnings. To release the winnings, they must be wagered several times over.

Reload Bonus

You can also claim a reload bonus as a regular online slot game player. It’s a good way to earn free money after your welcome bonus has expired. Typically, an online casino will only match the reload 25-50%.

To claim a reload bonus, make another deposit and opt in to the promotion. Play your favorite online slots and clear the bonus funds, remembering to meet the wagering requirement.

Keep in mind, always view the terms and conditions related to any bonus you are considering. This will help you to understand what you will need to do to maximize your slot bonus. Quick Tip: Be on the lookout for large bonuses with low playthrough requirements.

Slots Tournaments & Leaderboards

Some casinos offer slot tournaments and prize giveaways. Play a number of free spins within the allotted time period. The highest winners will climb the leaderboard and claim a share of a prize pool.

Loyalty Program

As a regular slots player, you will be eligible to join a casino loyalty program. Play regularly and earn points the more you gamble. As you earn player points, you can claim privileges like faster cashouts, free spins and prize giveaways.
