What a Top US Slots Casino Offers You
You can now play legal online slots for real money in many US states. Here are five reasons why online slots beat land-based slot machine games:
✅ Enjoy Your Favorite Land-Based Slots Online: Many US slot developers have adapted their land-based games for online casinos. The good news is that online versions are virtually identical to their land-based cousins.
✅ Play Slots Anywhere, Any Time: Why travel miles to have fun at your nearest brick-and-mortar casino when you can gamble online? That’s the beauty of playing online casino slots. Just fire up the PC or laptop and gamble for real cash any time you like.
✅ Find Higher RTPs Online: Some of the best land-based slots have RTPs up to 95 or 96%. Depending on the state, land-based casino slots' RTP may be in the mid-'80s. You won't find that at our recommended real money online slots; period. There are plenty of legal online slots in states like New Jersey that have RTPs up to 98%. Ultimately, if you are looking for a win, an online slot casino might be the better choice.

Is Playing Online Casino Slots on Mobile Possible?
You can also play hundreds of online slots for real money through your portable device. Download a native app or log in and play through your web browser. Real money slots apps are easily available and you can even make deposits using your smartphone.
Mobile slots differ from online slots as they are adapted to work on your specific OS. The game screen will be smaller and you can access the paytable and other information with the swipe of a finger. We find that playing slots on a casino app can be enjoyable and very easy to get started.
How To Download A Casino App
iOS (Apple): Most online casinos in the US offer download apps for the iPhone and iPad. After registering your account, simply visit the App Store and download the client. The software is free but you will need to have iOS10+ running on your device.
Android: The Google Play Store doesn’t supply native apps in 2020. Alternatively, you can download mobile apps direct from the casino’s homepage. When prompted, choose the Settings and turn the ‘Unknown Sources’ option on. For most casino mobile sites, you will need to run Android 5.0 or higher.
Instant-Play: Many regulated casinos also let you play mobile slots through your browser. Simply log in to your favorite casino site through your smartphone or tablet and load up a game in your mobile browser. Slots programmed in HTML5 work perfectly on whatever platform you are running.

Online Slot Machine Basics
Little to no skill is needed to play slots. Let us guide you through the basics of slot machine play.
How to Play Online Slot Machines
Online slots are played on a series of vertical reels filled with symbols. In every game, the reels spin and randomly come to a stop thanks to a random number generator (RNG) that is regularly audited to ensure fairness. You win money by lining up matching symbols on paylines that run horizontally across the reels (though a few games have vertical or diagonal paylines, too).
First, you need to select your coin size and the number of paylines you want to bet on. Some slots have fixed paylines where you will have to bet on every possible combination.
Online Slot Bonus Features & Rounds
Most modern online slot machines feature a bonus round. The bonus can be triggered at random or by landing the required number of scatter symbols. These are symbols that payout regardless of where they land on the reels. Common slot bonuses include:
Free Spins: You receive a number of free games, sometimes with a prize multiplier attached.
Prize Wheel: You win a spin of a prize wheel that contains free spins, multipliers or jackpot cash sums.
Wilds: Wilds are joker symbols that help complete a winning combination across the reels. Wilds sometimes have prize multipliers attached.
Cascading Reels/Re-spins: In a slot with cascading reels, winning symbols are removed from play, allowing symbols sitting above on the reels to fall into their place. You then receive a free reel re-spin. Consecutive winning cascades are usually awarded with a progressive multiplier.
Pick ‘em Bonus: In a pick ‘em bonus, you get to choose from 10-12 hidden symbols on the screen. Behind each symbol is a cash prize, free spins or multiplier. Keep choosing symbols until the “Collect” sign appears.

Online Slot Strategies to Consider
Online video slots are simple to learn and play. But how can you make the most of your gambling bankroll? Follow our five easy tips.
1. Choose the Highest RTP
Every slot has a theoretical RTP built into the game. Always check the paytable first to see what the average payout is. The higher the RTP, the better the long-term payouts and the better your chances to win.
2. Choose a Game You Enjoy
There are thousands of online slot machines to choose from. It’s important to select a slot that you won’t get bored of. Choose a game with an interesting theme or characters, and make sure you care about the bonus features.
3. Test the Volatility with Demo Play
Some slots will have a low hit rate. That’s the frequency with which a game pays a prize. Volatile slots might decimate your bankroll before awarding a big prize. Test these games out with play credits first to see whether they have high or low variance by playing free online slots.
4. Increase Your Stakes for a Progressive Jackpot
Progressive slots award a big jackpot at random or through a special bonus game. But progressives will usually award big prizes to players who pay the highest stakes. Try increasing your coin size and take a shot.
5. Claim Your Casino Free Spins
The best US gambling sites will award free spins to new signups. As a regular player, you can also claim bonus spins on a Slot of the Week. Take advantage of these bonus promotions when you play online slots for real money.
States With Legal Online Casinos
Online casinos are now perfectly legal in many US states. Some states even offer a mix of legalized online sports betting and poker alongside casino games. For instance, Illinois online casinos aren't yet legal in the state but you can still play video slots online. Remember, you can join up with regulated online casinos anywhere in the USA. However, you will have to be located within those states to be able to log in and play games for real money.

Michigan joined the party with legalized online casino gambling back in 2019. In one fell swoop, Gov. Gretchen Whitmer put pen to paper on blanket gaming laws regulating casino games, poker and sports betting.
