Are Online Slots Legal in the US?
United States online casinos are legal and live. You can play slots and table games in Detroit, Flint or Lansing. The first legal United States online casinos launched Jan. 22, 2023. So, which games can you play for real money? Read our expert guide to legal USA online gambling sites to find out.
Gov. Gretchen Whitmer signed into law a raft of proposals in late 2019 opening the way for legalized internet gaming, creating gambling options from online poker and casino games to slots and online sports betting.
The Lawful Internet Gaming Act provides a framework for online casino operations in the state. The current target date for online slots in the United States to launch is late 2023 or early 2025.
The United States Gaming Control Board (MGCB) has the power to provide licenses to online casino operators in the state as well as regulate them to make sure they are fair to players. Online United States casino sites offering slots must pay a license fee and must be partnered with existing land-based operators in the state. You will be able to play United States online slots if you are 21 or over.
Why Play Slots Online in the US?
What are the benefits of the United States online slots? Simply, you never have to visit your local casino again to play the latest games or be disappointed because your favorite slot machine isn’t available. Turn your PC or mobile phone into an all-powerful casino at the touch of a button at the gambling site of your choosing.
Here are some of the pluses of playing online slots in the US:
Enjoy Slots at Home or on the Move: You’ll can play United States online casino slots on your PC, Mac or smartphone with an online casino app. Enjoy internet gambling at home any time of the day.
Wide Variety of Games & Brands: United States online casino sites offer a huge variety of slots you just won’t find in a land-based commercial casino, even major ones such as the MGM Grand Detroit. Play classic 3-reel games or the latest 5-reel branded slots.
Play for Free or Low Stakes: United States online gambling sites offer free slots, direct from the lobby. That’s a benefit you just won’t find in a land-based casino. When you’re ready to play for real money, try low-stakes slots at $0.01 a spin.
Claim a Free Spins Casino Bonus: United States online slots sites offer new players the chance to win free spins on popular games. Convert your winnings into real cash with zero risk.
Will United States Online Slots Differ from Traditional Slots?
You may have already played slot machines in one of America’s land-based casinos. So, how will online slots differ from offline games?
RTP: Under United States state law, every land-based slot machine must pay out at least 80%. But you will find much higher RTPs in online slots at United States online gambling sites. Many of the best legal slots in the US have RTPs as high as 98%.
Range of Stakes: minimum stakes at a Detroit casino may start at $0.05 a line. Most online slots in the United States have low minimum stakes of $0.01 per payline.
Playing the Games: Classic slots in a land-based casino use physical buttons and mechanical reels to determine each spin. United States online casino slots use computerized programs and random number generators to calculate every outcome.
Free Play: The biggest difference between offline and online slots is the free-play option. You will be able to play United States online slots for free with no risk to your bankroll. Get a feel for the rules and bonus features before making a deposit.
RNG (Random Number Generators): Both offline video slots and online slots use RNGs to determine each spin. These are programmed into the machine’s software to guarantee a random spin every time. At a regulated, legal online casino in the United States you’ll know every game is fair. You can’t say that about an illegal, offshore gambling site, which is why we say to avoid them.
Progressive Jackpots: Progressive jackpots are special prizes formed of bets from every eligible spin. The longer the jackpot goes unclaimed, the bigger it gets.
Michigan’s land-based casinos already have progressive jackpots. You will likely see progressive slots at the first legal online casinos in the US. The online jackpots won’t be as big as offline ones to begin with, and the range of games will be small.
Will United States Online Slots Be Fair?
It’s important that online United States casino slots are above board. Every online slot uses a random number generator (RNG) that guarantees a fair spin every time.
RNGs are regularly audited by testing labs to ensure that each spin is completely random. Regulated US states use an independent testing lab to make sure slots are fair at every licensed online gaming site.
United States online casino slots are reliable and safe. The United States Gaming Control Board Lab is responsible for testing casino slots in the state. The lab will likely be involved in testing United States slots for fairness.
Will United States Online Slots Casinos Have Bonus Offers?
Yes, bonus offers are available. Casinos are eager to pull in new customers, and they achieve this via a range of exciting bonus offers.
Slots bonus promotions will differ from casino to casino, but here are some of the common offers you may find. Remember to always read the terms and conditions for every offer.
Welcome Bonus: The welcome bonus is the first promotion you will be offered after sign-up. After making your first qualifying deposit, the online casino will match it 100% with bonus money. The maximum deposit may be high, as much as $1,000.
You will then have a few days to clear your bonus funds by playing your favorite slots. The more slots you play, the faster you can unlock your free money!
Free Spins: Many welcome bonuses come with a free spins promotion. You’ll earn a few free spins to play on selected video slots. You can keep any winnings you make as long as you meet the wagering terms. This may involve gambling your winnings several times over before they can be unlocked.
Reload Bonus: Once you’ve cleared your welcome bonus, you may be eligible for a reload bonus. The reload bonus is like a deposit match bonus but the maximum amounts will be smaller. The casino may also match the deposit only 25-50%.
Loyalty Program: You can join a casino loyalty program if you are a keen slots player. Play slots and games for real money to earn player points. The more points you earn, the more benefits you can unlock.
VIP program benefits will vary from casino to casino. You may be able to earn faster cash-outs, bespoke bonuses and free spins or access to a personal VIP manager.
Types of Slot Machines Coming to the US
Hundreds of the best United States online slots are now available. But what types of slot machines will you be able to play on your PC, phone or tablet?
Classic Slots
Classic slots are similar to the nostalgic 3-reel games you’ll find in a Detroit land based casino or tribal casino in the US. Classic slots feature one or two paylines and no bonus features. The symbols may be dominated by fruit and classic symbols like bells and 7s.
5-Reel Slots
Most United States online casino slots will be 5-reel games. 5-reel slots contain more paylines and can accommodate special symbols like wilds and scatters. They will also boast at least one bonus feature like free spins or a prize wheel.
Slots With Bonuses
Most United States online slots will carry at least one bonus feature. It could be as simple as a wild symbol, which acts like a joker to replace all regular symbols in the game. You will also find scatter pays, which pay out wherever they land on the reels. Land 3 or more scatters and you will trigger a bonus round like free spins or reel re-spins.
The best slots make use of powerful software design. Bonus features can be incredibly elaborate, offering more ways to win every time you play.
Branded Slots
The best slots developers strike deals with music and film companies to develop branded slots. Branded slots are based on existing TV shows, films or celebrities. They may feature actual audio or video footage to provide an immersive experience.
3D Slots
Advances in casino gambling technology mean that modern video slots boast better sound and graphics than ever. 3D slots feature HD graphics and animated symbols that perform special tasks on the reels. 3D slots usually offer the most interesting bonus games for players.
Progressive Slots
Progressive slots offer the biggest jackpots. A small chunk of every bet contributes to a larger jackpot. You can win the jackpot at random or by playing a unique bonus game. The longer the jackpot goes unclaimed, the bigger the jackpot gets.
With online slots just recently launched, progressive jackpots may start off low. But as more players begin to sign up to online casinos, the jackpots will grow.
Can I Play Online Slots on Mobile in the US?
You can play legal online casino slots in the United States via your smartphone or tablet. Download a casino app for your Apple or Android device or play through your mobile browser.
Mobile slots are just like online slots, but they are specially adapted to work on a touch screen. Adjust bets using a slider and spin the reels with a tap of a button.
You’ll also be able to download full casino apps to your portable device. Install a native app and download your favorite slots to your handset. You can even make real money deposits through the mobile casino cashier.

Common Slot Terminology to Know
You’re all set to play the best real money United States online slots. But if you’re new to online gambling and casino slots, you might be wondering what the various terms mean. Here’s our quick guide to the most popular online slot terms in 2023.
Coins: Before you play a slot, you must set the coin size. The coin value usually starts at $0.01 but can be as high as $100. Then, set the number of coins. You might be able to bet 1-10 coins per spin.
Paylines: Paylines run horizontally across the slot game screen. When you match symbols on a payline, you win a cash prize. The number of paylines varies from slot to slot. Classic slots feature one or two paylines but modern 5-reel and 6-reel slots can contain hundreds or thousands of possible paylines.
RTP (Return to Player percentage): Every slot has an RTP programmed into it. It’s the theoretical payout made by the slot over millions of spins. A good online slot RTP would be 95-99%. That means for every $100 paid in, $95-$99 is paid out. The rest is retained by the casino.
Reels: All slots are comprised of reels. Reels are vertical drums containing multiple symbols in a set pattern. The reels spin independently and stop at random on each game. You win cash if you match symbols on horizontal paylines running across the reels.
Paytable: The paytable displays information about the slot, including payouts, symbols and bonus details. You’ll also find a list of available paylines and sometimes the game’s RTP.
Variance/Volatility: Variance refers to the win frequency of the slot. A low-variance slot pays lots of small cash prizes, while a high-variance slot pays out big jackpots less frequently. Often, United States online slots with lots of bonus features will be high-variance. You may lose a lot of spins before hitting a big winner.
Bonus Features: Most modern online slots in the United States will have a bonus round. Bonuses are triggered at random or by hitting scatters on the reels. Bonuses can include free spins, prize wheels or a trail bonus featuring multipliers and cash prizes.
Wilds: Wild symbols act like jokers on the reels. They fill in the gaps on paylines to complete winning combinations. Some new online slots feature special wild modifiers like win multipliers. The wilds may expand to fill an entire reel or replicate across multiple reels at once.
Scatters: Scatter pays are special symbols that will pay out regardless of where they appear on the reels. Scatters don’t have to form part of a winning payline to award a prize. Scatters are also important for triggering a bonus. Most bonus features are activated by landing three or more scatters anywhere in view.
Jackpot: Every slot has a maximum payout, called the jackpot. You’ll find a list of jackpot values in the slot paytable. The jackpot might be won during a regular spin, or it might be available during a bonus feature.
Free Spins: Free spins are the most common type of slots bonus. You will win a number of free games by landing the required number of scatters. Multipliers are sometimes applied to every winning spin.
