Mobile Slots: Play for Free or Real Money, Anywhere, Anytime!

When online slots and casinos first became popular, they were available only on desktops, and you’d even have to download a casino app in order to play. Those days are gone, as all online casinos are now accessible through your web browser, and they’re even optimized for smartphones. 

Thanks to this, and the fact that game providers also make sure their games are mobile-friendly, you can now play any online slot on your phone. There are actually many games that are even better for small cell phone screens than for big desktop monitors. 

In this Slotjava guide, we’ll be diving deep into the best mobile slots, which bonuses are available at mobile casinos, and answer all your questions about playing slots on your phone.

What Are “Mobile Slots”?

Mobile slots are simply slot machines that can be played on a smartphone. About a decade ago, these slots used to be quite rare, and a mobile casino would only contain a fraction of the games you found on the regular casino site. 

The first game providers that took some tentative strides within mobile games were Microgaming and NetEnt. The latter launched what they called NetEnt Touch, which was their game catalog for smartphones. Some of the first titles to be converted to mobile slots were their most popular desktop slot games, such as Starburst, NetEnt, and Reel Rush. 

Casino apps used to be the way to access mobile-optimized slot machines, back in the day. But that all changed when technological advancements led us away from Flash and to HTML5. With HTML5, a website, and its content, are responsive, which means that it adapts to fit your screen. This was the big breakthrough that led us to the mobile slots that we know today. 

It was around 2015 that the big change came, and all game providers started making their games mobile-optimized with HTML5. Then, they started updating their older titles, naturally prioritizing their most popular and successful games. Making all the updates took time, and it’s just a couple of years ago that we started seeing just as many slots available on a casino’s mobile site as we did on their desktop version. 

Today, it’s taken for granted that any new slot machine game can be played on any device, directly through a web browser. This also made casino apps somewhat redundant, as it’s simply easier to play instant play slots in a browser than having to first download the casino’s app. 

As long as you have a device with an internet connection and a web browser, you can play perfectly optimized slots. Most can even be played in both landscape and portrait mode. The buttons and some other elements might change place depending on your screen size, but other than that, the games are exactly the same as the ones you play on larger screens or monitors. 

Playing On Your Mobile Browser

The easiest way to play mobile slots is by playing through your browser. If you want to play slots for free, you can stick around here and try out as many of the 2200+ demo slots in our catalog. However, if you want to play for real money, you will need to check out our list of the best online casinos and make your deposit there.

If you want to avoid downloading a casino app, instant play in your browser is your only option. The games load within seconds, and you can use whichever browser you’d like, such as Safari or Google Chrome. 

The only thing you need to keep in mind is that it’s recommended to play slots via a Wi-Fi connection unless you have a large data bundle for your phone. If not, playing slots for hours can be costly using a 4G or 5G connection.

Slot & Casino Apps

Some casinos still offer a dedicated app for you to download and play through. These apps are always made for both iOS and Android so that you can play no matter what type of phone or tablet you have. You’ll find the apps by following a link from the casino’s website, or in the Google Play and App Store. Downloading these apps is for the most part always free of charge.

A casino app is basically the same as the browser version of the casino. The difference is that you enter the casino through the app, and you’ll need to regularly update the app to ensure you have the latest version. 

There are always pros and cons to using a casino app, and here are the most important ones: 


  • You can easily sign in using Face ID or your fingerprint
  • The casino might offer you an exclusive bonus to download their app
  • Your casino session won’t be saved in your browser history


  • The app will require updates, and it takes up space on your device
  • Some games are not added to the app as quickly as to the casino’s website
  • You can only access the casino app on the device it’s been downloaded to

If you’d like to play at an online casino that offers an app, you should check out BetMGM, Caesars Palace, or Draftkings.

Reasons You Might Want To Play Mobile Slot Games

The slots you play on mobile are exactly the same as the ones you play on your desktop. The payouts are the same, the RTP and volatility are the same, and you can expect the same great graphics and immersive games. Bonus features and mechanics will also always stay the same. 

But, there are some advantages to playing mobile slots that can’t be found when playing on a  laptop or desktop. Here are our top five reasons why you should opt for mobile slots:

  • Play from anywhere: As long as you have your phone with you and you have an internet connection, you can play. It doesn’t matter if you’re at home, at work, on the bus, or visiting your in-laws — mobile slots are always an available source of entertainment. 
  • Play anytime: No matter the time of day, online casinos through your phone are always open. There is no such thing as opening hours or specific times these games are available. 
  • Easier for shorter game sessions: Getting your phone out of your pocket and starting a slot machine takes a matter of seconds, which is great if you’re short on time. Get some quick spins in while commuting to work or waiting for the water to boil.
  • Unique slot app features: If you play slots using a casino app, you can get real-time notifications on your phone to stay informed about new bonuses, game releases, approved withdrawals, and more. 
  • Mobile biometrics for enhanced security: Playing on your phone can offer logins via biometrics, like Face ID or fingerprint, which keeps your account safe. It’s also easy to complete 2-factor authentication to approve logins and payments.

Bonuses for Mobile Slot Players

Most online casinos offer the same bonuses no matter which type of device you’re playing on. The bonus is issued to your account, and you can log in and claim it from your mobile as well as from your desktop. This goes for match deposit bonuses as well as free spins, cashbacks, high roller bonuses, and any other kind of casino bonuses

Exclusive mobile bonuses used to be a thing, back in the day when playing through a casino app was the norm. Many online casinos would give you a no deposit bonus with free spins for simply downloading their app. But ever since most casinos switched to mobile-optimized websites, this has become less of a thing. 

Claiming bonuses on your phone is easy, both from the mobile browser and an app. Typically, you log in, navigate to the bonus section of your account, and claim the bonus. You might also be able to claim a bonus directly from the deposit page, by either opting into it or by entering a bonus code. 

  • Welcome bonus: A welcome bonus is the first bonus you get when you join a new casino. Typically, you get a match deposit bonus, some free spins, or both.
  • Free spins: Free spins let you play a slot for free. There will be a set number of spins you can play and a specified slot machine. What you won from your spins is your bonus.
  • Recurring promotions: Most casinos offer fixed ongoing promotions that you get to claim weekly. These offers can include any kind of bonus, but it’s typically deposit bonuses.
  • VIP & loyalty programs: It’s fairly standard for a casino to have a VIP or loyalty program. Through these programs, you can claim rewards based on your activity, such as cashbacks. 
  • No deposit: No deposit bonuses aren’t very common, but they do exist. Some casinos offer some free cash or free spins when you sign up. Active players can also get these bonuses, once in a while.

  • Potential to win high payouts: If you hit a really big win in a slot game, you’ll be glad to realize that it’s real money you play with, so you can cash it out.
  • Excitement that comes with real money play: Free slots are exciting, but nothing compares to the thrill of knowing that there is real money at stake.
  • Loyalty programs: Many online casinos have loyalty programs where you get rewarded with special bonuses for playing slots and other games.
