Without a doubt, mobile slot machine apps are the most popular 18+ mobile gambling games in the world. With simple controls, cutting edge animations and sound effects, and compelling “one more spin” gameplay, mobile gambling apps for 18-and-up players are literally where the money is. That’s why, regardless of the legit online 18+ casinos you choose, you’ll see slot apps featured front and center.
Of course, real money gambling apps aren’t just popular because they’re accessible or convenient. They’re also popular because – more than any other online gambling game – online slots replicate the look and feel of electronic Vegas spin games down to the last detail. So, if you’re after the best casino app experience, we’re here to help you pull the handle, not pull your leg!
Are 18-And-Up Real-Money Mobile Slot Machine Apps Legal?
Yes! While bandits might be scofflaws, one-armed bandits are 100% legal in the United States. In legal gambling states where domestic online casinos have been authorized, you can simply download your local vendor’s official slot machine apps for iPhone, iPad, or Android right through the App Store or Google Play store. However, these are universally limited to players aged 21 and up.
If you live in a state that hasn’t legalized iGaming yet – or if you’re under the age of 21 (i.e. 18 and up) – you can still play real-money casino apps online safely and legally by joining any of the offshore casino sites featured here. These venues operate in full compliance of all United States gambling laws, and every site accepts players at 18 and over.
Note: Washington state has nominal laws against all online gambling, including real-money spin wheel apps. While these laws don’t actually seem to be enforced, we still recommend that you abide by all local gaming mandates and play mobile casino apps for real money only at your own risk.

Best iPhone Slot Apps For 2024
For most players looking for legit real-money slots, mobile blackjack apps, or 18+ online mobile roulette, iPhone is the platform of choice. It’s the most popular smartphone line in the world, and the best online casino games for iPhone outrank most other popular App Store apps. But there’s a catch: The downloadable iPhone slot games you find in the App Store don’t let you win real money.
These apps definitely charge you real money in the form of in-app purchases (IAPs) for more spins or playtime, but you can never win actual cash or monetary rewards.
As such, if you want the best slots apps, 18+ iPhone gambling fans should avoid the App Store and head over to one of the sites linked here. These legal online casinos let you play mobile slots for real-money payouts, and there’s nothing to download or update, either. As long as you have an up-to-date version of mobile Safari up and running, you can access the best iOS spin games on any size of iPhone from anywhere in America.
Best iPad Slot Apps For 2024
After iPhone slot games, real-money gamblers prefer hitting the reels on the iPad’s larger screen. The iPad is especially good for more casual play, making it the platform of choice for mobile gamblers who aren’t always on the go. But as with iPhone casino apps, the iPad slot machine apps in the App Store aren’t real slots. They look and feel like real spin games, but you’ve got to pay to play and have no opportunity to ever score a payout.
So, if you’re looking for the best casino apps for iPad, you’ll need to look at the sites listed here. Just visit any link on this page using your iPad Safari browser, and you’ll get access to the best gambling apps for iPad, hands down.
These 18+ iPad gambling sites require no downloads, no updates, and no geofencing restrictions, so you can play from literally anywhere, anytime – even though you’re usually going to enjoy these real iPad slot games from the comfort of your easy chair or cozy sofa.
Best Android Slot Apps For 2024
While the mobile online gambling market used to cater more to the iOS crowd, iOS games are no longer the exclusive emphasis. Yes, most legit online casinos develop their games around iDevice specs first and foremost, but with modern responsive design technology, the best slots for iPhone work just as well – and just as seamlessly – on Android devices of all makes, models, and screen sizes.
That said, as with iOS games, Android slot games in the Google Play store are not real money games. That is, you can’t win real money when you “win” the games.
As a result, if you’re after Android slots that pay real money, your best option is to sign up at one of the reputable online 18+ Android gambling sites linked from this page. These sites offer the best online casino games for Android because they actually have legitimate, fair payouts and never charge IAPs or microtransactions. Just make a deposit, place your bet, and pull the digital lever.
Types Of Mobile Slot Games At 18+ Online Casinos
When you want to win real money, slots apps aren’t all created equal. Yes, all the titles at the sites we recommend are legit RNG (random number generation) slots games made by the foremost online casino software developers in the industry. And yes, every legit game in these mobile slot suites has true-to-life odds and payout rates.
However, different casino games have different pay lines and different winning combinations. Some even have mini-games and other embellishments for added value.
Luckily, even though the best sites each offer well over 100 mobile slots games to choose from, it’s easy to find your favorites. Navigating these massive selections is simple because the games are organized by type within each site’s real-money slots app portal:
- Mobile 3-Reel
- Mobile 5-Reel
- Mobile 6-Reel
- Mobile 3D
- Mobile iSlots (Interactive Slots)
- Mobile Progressive Jackpot
And even sites that don’t have free gaming apps (like Bovada Casino) have low enough slots betting limits that you can effectively play for just a few dollars per session – unless, of course, you break even or win big!
18+ Online Slots Tournaments And Special Events
One of the hallmarks of the best slot machine apps that pay real money is that the sites hosting these games run daily and weekly online tournaments that let you win even more money than usual. Daily tournaments range from small to medium jackpots, while weekly tourneys or special seasonal online slots tournaments can have jackpots in excess of millions of dollars.
Generally, online tournaments have entry fees ranging from $1 to $20 or more, depending on their sizes and prizes. However, because most sites have rewards programs, you can often score free tournament entries using your site rewards points.
Every reputable 18-and-up online gambling site posts its updated online tournament schedule on its home page, so you’ll know exactly when it’s time to yank the crank on each event.
18-And-Up Mobile Casino Slots FAQs
What is the best iPhone slot machine app?
If you want to play real iPhone slots for real money payouts, the best options are going to those sites we feature in our 18+ mobile gambling guide. Remember, none of the downloadable iPhone gambling apps in the App Store let you win real money. Therefore, if you actually want something to show for your online jackpots, the browser-based mobile casino sites featured here are the best options.
What is the best iPad slot machine app?
As with iPhone, you won’t find the best iPad slots app on the App Store. While there are plenty of iPad casino apps, these are video games, not real casino games. So, you can win, but you can only win more spins and more coins, so you can keep playing. There are no real payouts for the downloadable iPad slots apps available in the App Store, but that’s irrelevant because the best casino apps for iPad are available at all the legit 18+ online casinos featured here.
What is the best iOS slot machine app?
When it comes to online casino action, iOS casino games may look the part, but they don’t play the part. Or, rather, they don’t pay the part. That’s because iOS games are video games, not real casino games. You can earn extra spins and extra coins to extend your gameplay sessions, but there’s no way to win any real money. For the best iOS casino app, any of the online offshore 18+ gambling sites we recommend let you play for real and win real money.
What is the best Android slot machine app?
As with iOS, real-money slot apps for Android are not available. Android games downloaded from the Google Play store are free to play – but you can only spend money, not win money. If you want the best online casino apps for Android, the 18+ online casinos we recommend here have over 100 different games to choose from, each developed by the top casino software companies in the world. These are, without a doubt, the best slots games for Android on the Internet.
What is the best slot machine app to win real money?
Any of the 18+ online casino sites we recommend can be considered the best online slots apps for real money payouts. While there are plenty of fun casino games on the App Store and Google Play store, remember: These don’t let you win actual cash. Note: In the few states with legal online casino gambling, online gaming apps are restricted to players aged 21 and up.
Do 18+ online casinos have free slots apps?
Many of the sites featured here have free slot machine apps, but free mobile casino games are not universally available. Still, even at the top-rated 18+ online casinos that don’t have free casino slot apps to play, the minimum bet limits are so low that with a small $20 deposit, you can play hundreds of spins and win real money payouts, too.
Are there free slot apps with real rewards?
Not really. If you download a free slots game from the App Store or Google Play, you can “win” more spins or more coins so you can keep playing, but that’s it. These aren’t what we’d call “rewards” in the standard casino sense. Similarly, if the online 18+ casino of your choice offers free slots, you also won’t be able to earn site rewards with these – unless the free games comes in the form of bonus spins or free plays earned via deposit match bonuses.
What are the best free slots for iPhone?
If you’re after the best free slots app, iPhone users aged 18 and up shouldn’t bother with App Store casino games. Casino apps in the App Store don’t let you win real money, but they also don’t let you play for free for very long. Free gambling games for iPhone are powered by in-app purchases (IAPs) that require you to pay real money to get more spins. The best free wagering games for iPhone are exclusively browser-based and available at the sites we recommend here.
What are the best free slot games for iPad?
There are plenty of free slot machines for iPad on the App Store, but as with iPhone, these free games for iPad are only free for a minute or two. After a few spins of the reels, you’ll have to pay actual money to buy more spins or more online casino coins to keep playing. And as with all free app slots, iOS for iPad don’t let you win real money. Thus, the best free casino games for iPad can be found online at the offshore 18+ casino sites we recommend here.
What are the best free slot games for Android?
As with iPhone and iPad, there are plenty of free slot games for Android phones and tablets. But if you want the best free casino app for Android, you won’t find it in the Google Play store. That’s because, just like with iOS games, the free penny slots for Android are free in name only. They all require microtransactions for extended play, and none offers actual cash payouts. Of course, many of the sites we recommend offer free gambling games for Android with the added bonus that you can switch to paid Android slots for real money payouts whenever you want.
