Mobile Slots

Play mobile slots games for real money at one of the top-rated mobile casinos we've listed below. Every mobile site and app we recommend offers:

  • 100s of real money slots, including video slots and jackpot slots.
  • Huge welcome bonuses and promotions
  • Compatibility with Android and iPhone

How Mobile Slots Work

Getting up and running with mobile slots is easy, even if it’s your first time. Just follow these simple steps to get set up:

Make sure you have a smartphone or tablet and either a data plan or access to Wi-Fi.

Be aware of how much data you have on your cellular plan to make sure you don’t go over playing slots.

If you’re concerned about your data limit, try to use Wi-Fi whenever possible.

Don’t worry about installing an app. All online casinos we recommend offer mobile slots on their websites, so you can play using your web browser.

Make sure to use our special links to sign up for a new account and you’ll be eligible for special deposit bonuses (including no deposit bonuses and free spins) we’ve negotiated for our mobile slots players.

Sometimes you can even pay by mobile. Slots are designed for easy deposits and withdrawal to get you playing quickly and easily.

Even when you’re at home, using a tablet can be way more convenient and comfortable than using a PC or Mac. Once you try it, you may never want to go back to playing on your computer.

Play Mobile Slots for Real Money

Playing real money slots is always an exciting prospect, but the ability to do so on the move creates a whole new world of freedom for players. Many of the best software developers (like NetEnt with its Touch slots) have optimized the graphics and gameplay features for most of their slots, specifically for mobile.

The only downside is that some online casinos have a smaller list of games for mobile players, but there’s still usually enough to keep users interested.

Why You’ll Love Playing Slots Apps on Your Mobile Device

There are hundreds of thousands of apps and games on the App Store and Google Play but rarely can you actually win real money. Mobile slots are different. With just a few taps, you can actually win big bucks watching the reels spin and there’s no download necessary.

The chance of winning is just the start. There are many reasons why you’ll enjoy playing mobile slot games:

It’s convenient

You don’t have to pop open a laptop or head up to your desktop when you have the urge to play and win real money. Just grab your smartphone and you’re good to go with no download needed.

It’s discreet

When you’re on your phone, no one can see if you’re playing online slots. With a small screen, you’ll be just as inconspicuous playing slot games.

Types of Slots

Real Money Slots

Real Money Slots

Playing slots for real money is a risk but can also be rewarding. Wins are usually gained by matching symbols on a payline, or via one of a myriad of possible bonus games that are triggered from the slot's base game, usually via scatter symbols.

Play real money slots
Jackpot Slots

Jackpot Slots

Jackpot slots have a fixed jackpot, or a progressive jackpot that builds up over time. These slot titles will usually provide other gameplay features, but it is the jackpot that players are hoping to hit, with the potential to win millions in some cases.

Play jackpot slots
Penny Slots

Penny Slots

A penny slot is, simply, a slot that can be played for a penny (or a cent) per spin. These are popular slots because of the low minimum bet. However, prizes are usually lower when betting a penny at a time on a slot game.

Play penny slots
Video Slots

Video Slots

Video slots are modern slot games with immersive graphics. Presented in 3D, these slots are almost unrecognizable from the fruit machines that preceded them, often involving exciting bonus features, video slots can also include animations, movie footage, and more.

Play video slots
Vegas Slots

Vegas Slots

Vegas slots are traditional style slots that made their name on the floors of Las Vegas' famous casinos, before making the move to an online environment. IGT's Cleopatra is arguably the most famous example of a Vegas slot.

Play Vegas slots
Free Slots

Free Slots

Free slots are titles available to play for no money. While real money wins are not usually possible, free slot games provide a good way to develop a slots strategy and try out new titles without risking any of your casino balance.

How to Choose the Best Mobile Slots Casinos?

There are some important factors to consider when choosing a mobile casino, including:

Look for the best developers Look for the best developers

You want to know you’re getting the best mobile slot games, so an online casino should be offering titles from the best software providers in the industry. Popular developers like Microgaming, NetEnt, and Yggdrasil will ensure you’re getting the best possible playing experience.

Safety and fair play Safety and fair play

Not all online casinos are created equal. Look for online casinos that offer random number generators (RNGs) to ensure fair play. Our recommended mobile casino sites also use SSL encryption technology and firewalls to keep you and your information safe.

Range of games Range of games

Some online casinos cut a lot of games for their mobile version. Look for mobile casino sites that provide a wide range of slot games, as well as a decent number of table games and live dealer titles to enhance your overall gaming experience.

RTP matters RTP matters

Slot games have individual return-to-player percentages (RTP), and so do online casinos. Check the RTP of an online casino, if it’s under 90%, or even close to it, then your chances of winning are probably lower than they would be at the best mobile casinos.

How to Win on Mobile Slot Machines

There is no way to guarantee wins on mobile slot games due to their random nature. However, there are some things to keep in mind that may help.

Check the RTP

The RTP shows the average payout of a slot game, for example 95% = $95 per $100. While the RTP of a slot should never be considered a guarantee (it’s an average taking from thousands of spins) the higher a RTP, the more likely you are to strike some wins.

Choose bet amounts carefully

How much you bet effects how quickly your budget may decrease. If you are betting high, wins could be bigger, but you may also lose your budget faster. Sometimes betting little amounts is a better long-term plan and offers longer gameplay.

Risk vs reward

The volatility of a slot shows how the game tends to pay out. High volatility slots tend to pay out less frequently, but in bigger amounts. On the other hand, lower volatility slots will usually payout little and often. Pick a volatility that matches your playing style.

Look for free spins bonuses

Casino promotions offering free spins tend to have the lowest RTP percentages. This means that if you win, you’re more likely to be able to withdraw winnings without betting any of your own money. Look for mobile casinos with regular free spins bonuses where possible.

Play for free first

Free games or demo slot games won’t win you any money, but they will give you a chance to decide if a slot is for you. This risk-free gameplay lets you check the RTP and volatility and how it effects a slot’s payout behavior and practice your slots strategy.

Mobile Slots FAQ

Do I need to install an app to play mobile slots?

Not necessarily. While some casinos have dedicated slot apps, many sites let you play directly through your web browser, regardless of which device you’re using. In many cases, the navigation bar disappears, so it feels just like playing an app.

Which devices are supported?

Many mobile online slots sites support iPhone, iPad, Android, BlackBerry, and Windows devices. Basically, virtually every smartphone and tablet on the market can be used to play mobile slots for real money.

Is the tablet mobile slots experience the same as on a smartphone?

For the most part, it’s exactly the same, but bigger. Some casinos offer slots games on tablet that aren’t available on a smartphone. The reason for that is screen real estate.

Can I access the same slots games on my mobile device that I do on my desktop?

Yes. Many of your slot favorites that you play on your PC or Mac have been ported over for real money mobile play.

Can I win real money playing mobile slots?

Definitely. All the mobile slots sites we recommend let you play for real cash, so you can take a real-world casino experience wherever you go, as long as you have an internet connection.

What if I just want to play for free?

You can do that too. All our picks let you test the waters with free games. Keep in mind that some casino apps and sites require you to create a free account to get started.

Are the jackpots the same on mobile slots as they are on the desktop?

For the most part, yes. Progressive jackpots link the jackpots of various machines across the same network. So someone on a Mac could be feeding the same online slots jackpot as someone on an Android.

Can I deposit from my mobile slots app?

Absolutely. Each mobile slots casino includes a dedicated cashier where you can deposit funds and withdraw your real money winnings.

Do I need a separate account? Or does the same account work just fine?

The same account. If you deposit on mobile, you’ll be able to play mobile slots using the same username and password that you use to play slots on your desktop. Whether you’re on a Mac, PC, or a mobile slots app, the same account gets you to the games fast.
