Online Slots Mobile
Mobile online slots have been getting more traction recently

Free Mobile Online Slots

There are two main sources where mobile users can play online slot games for free. One of them is social casino apps. We'll talk about the second one a bit later.

Social Casino Apps

¡Social casino games don't pay real money!

¡Your success on social casino apps is irrelevant when it comes to online gambling to win real money! (We'll cover the reasons why further down)

Naturally, the first places to look for mobile online slots free games are the App Store and Google Play Store for Apple and Android devices respectively. Indeed, typing "online slots" in the search box will return a myriad of online casino apps where you can play online slots for free.

However, it is important that players understand that those aren't real payout online slots. You CANNOT win real money playing slots on those apps. They are so-called online social casino apps.

On social casino apps, players are given a certain amount of free coins to play slots online. Once a player has run out of free coins, they have to spend real money and make in-app purchases to get more coins to continue playing.

Nevertheless, social casino games are action-packed and quite entertaining. All social casino apps are pretty similar. In the beginning, players have access to a handful of online slots. The more and higher bets players place, the faster they move up the progress scale which allows unlocking more online slots games for fun. Social casino slots are filled with bonus games and free spins, so get ready for a close encounter with a dopamine rush!

Remember, you have to be of legal age to play this type of games (21+ for the US, 19+ for Canada, but mostly 18+).

We also believe that it is solely a player's decision whether to make in-app purchases or not.

Best Social Casino Apps for Android and iPhone

Social casino apps have a wide choice of online slot titles - from classic three reel slots to newest video slots with great graphics and intricate gameplay with expanding wilds, free spins, hold-and-respin feature, and others.

Here are the top-3 social casino apps with over 10 million downloads each and highest ratings by players.

Club Vegas

App Store rating: 4.8☆

Google Play Store rating: 4.7☆

Club Vegas App
Club Vegas app is filled with bonuses and extras

Club Vegas app is one of the top mobile social casino games and for a good reason. Speaking of dopamine, Club Vegas will stimulate the reward center in your brain pretty hard. That is the main reason why I'm only half-way through with this article, but have already reached level 34 in under 1 day. LOL.

Anyway, to kick things off, every new player receives 10,000,000 coins as a welcome bonus. As you progress from level to level, you will receive more free coins bonuses and more online slots will be available to you. Unlocking some levels comes with a mystery prize (more free coins).

The amount of free coins seems mindblowing. However, the initial minimum bet is 6,000 coins which is equal to a minimun bet of $1 with initial bankroll of $1,666. By moving to higher levels, minimum bet will decrease, whereas maximum bet will increase.

What I personally love about Club Vegas is that they've created an entire community within their app - there's a chat room where you can make new friends; you compete for prizes with other players while playing social casino slots.

You will also get more coins for uploading a profile picture, as well as joining one of the many clubs which also compete with each other for bonus coins.

Epic Album will contain all your epic wins. I have won 25,000,000 coins once, and it didn't count as Epic, just as Mega Win.

If you wish to skyrocket your progress in the game, you can buy some special features, like access to piggy bank savings, daily spins, scratchers and much more.

All in all, Club Vegas is an amazing app with online slots mobile games that very much deserves the high rating that it has.

Jackpot World

App Store rating: 4.9☆

Google Play Store rating: 4.6☆

Jackpot World Casino App
Jackpot world casino app features a great deal of freebies, bonus prizes and quests

Jackpot World is another great social casino app. As you advance on the level scale, more free slots and other social online casino games will become available to you. Moreover, as you level up, you will get access to daily missions and rewards, side quests and games.

Players don't have to worry about running out of free coins, as they can collect coin bonuses every 15 minutes. And who doesn't like spinning a giant bonus wheel? Login Rewards, too, contain cool bonuses and freebies. Check in 7 days in a row to get epic prizes.

Higher levels will grant players access to Jackpot Quest and Treasure Rush board game. The more free slot games you play and the higher bets you place, the more Jackpot Stamps you collect. Collect all 288 stamps and win Epic Fantasy Final Prize of 50 billion free coins!

Apart from online casino slots, Jackpot World casino app features a great deal of extras, so we simply recommend checking the Event Center and the dashboard regularly for fun activities and bonus prizes.

Jackpot World is a great place to play slots online and other games. Unfortunately, same couldn't be said about online chatting with other players. Even though you can join one of the Unions that have in-app chat rooms, this feature isn't promoted in any way, so the chat rooms remain empty and lifeless. On second thought, it could be a great fun for an existing group of friends who want to have fun together online.

DoubleU Casino

App Store rating: 4.3☆

Google Play Store rating: 4.4☆

Doubleu Casino Online
Double U Casino Online gives players access to 200+ casino free online slots

The entire library of DoubleU Casino games is available for players right off the bat. I counted over 200 slot games. Furthermore, there is a video poker section where users can play Jacks or better, Deuces Wild and Double-Double Bonus games.

What I really love about DoubleU Casino online is its straightforward gameplay. Play the games, get daily free bonuses. Wish to get higher rewards, more coins and access to exclusive stuff? You can buy it.

Overall, it's a very nice app for casino free online slots with great selection of games without excessive paraphernalia. I'm sure you can find your favourite slot game on this app.

Free Online Slots Demo Mode

Remember, I told you that there are two sources to play online free slots? The second great source of free slots machine online is actually real money slots from the world's leading game suppliers that are perfectly available for free play in a demo mode.

You can visit websites of such software developers as NetEnt, Pragmatic Play, Betsoft, Wazdan, Play'n Go, Thunderkick and many others and find a myriad of popular free online slots for mobile phones and tablets.

Typically, real money online slots casinos also allow playing online slots for fun without having to sign up for a casino account. You can visit safe online casino sites like Club Riches, Playzee, Jonny Jackpot and Miami Club Casino (USA) to play real money slot games in a practice mode.

Mobile Online Slots: Real Money Play

Now, it is super important to understand that real money slot games online gambling has nothing to do with social casino games whatsoever. Online gambling is a multi-billion industry and it exists because of a such thing as house edge.

House edge is a pre-calculated mathematical advantage that a casino has over its players. All cash paying online slots has a hard-wired RTP (return-to-player) percentage. On average, online slot machines have RTP of 96%, meaning that a player can expect to get back $96 as winnings out of every 100 dollars wagered.

However, RTP cannot be applied to a single playing session, no matter how much you bet. You can spend tens of thousands of dollars on online gambling, but still a life-changing jackpot will be won by another player. These things are completely random.

So, unlike social casino games, there will be no streams of mega wins or epic wins raining down on you. That's why I like when a fun mode is actually called a practice mode. So you can practice as if you were wagering real money and see how it goes for you.

If you are looking for an online casino for mobile devices to play real money games, you need a real money online casino that supports mobile interface which pretty much all online casinos do. Mobile gambling sites offer a much greater selection of best online slots instant withdrawal compared to any brick and mortar casino.

Fastest Payout Online Casinos

Instant withdrawal casino offers a list of real money casino sites with best online slots from top-notch software providers. You can find a legit online casino for your region (US, Canada, UK, Australia, New Zealand, Ireland and more) that offers a generous welcome bonus for new players, biggest jackpots, instant payouts and huge variety of best online video slots for real money, table, card and live dealer games, and progressive jackpots. You can play on desktop or any mobile device.

To get hold of your winnings ASAP, fast withdrawal casinos employ a number of payment methods that allow players to cash out in a blink of an eye - crypto (bitcoin, ethereum, litecoin, dogecoin, ripple, USDT, etc.), web-wallets like Paypal, Neteller, Skrill, ecoPayz, MuchBetter and others, instant banking options like Interac and Trustly.

Traditional payment methods like bank cards (Visa, Mastercard) and bank wire are also available, even though they take much longer when it comes to withdrawing your funds from a gambling site.

How to play online slots responsibly?

This is a great question! Real money online gambling can be highly addictive due to its solitary nature. In fact, because it takes just a few clicks to fund your account and there's literally no one to stop you, it is fairly easy to get carried away.

First of all, you must treat online gambling as an entertainment and nothing more. You are NOT special, thousands of other players feel that the next spin will be the lucky one and change their lives. In reality, only a handful of people win life-changing jackpots.

Let's take Mega Moolah for an example. This progressive online slot, dubbed as millionaire-maker, has been around for 16 years already. During all these years, the Mega Jackpot has been won only by some 70 people. Out of hundreds of thousands players. Think about that!

The key principle for responsible gambling is to set your deposit limit, and in case of unlucky day, turn off your PC or mobile device, suppress the initial urge to top up your casino account and go for a stroll or something.

Anyway, keep your head cool and we wish you the best of luck!
