Best casino slot apps payout

There’s one simple way to establish the payout for slot apps – RTP (Return To Player). RTP is the amount of money that is paid back to gamblers over time – in other words, it’s your payout. 

How does RTP work? Like this. Say a game has an RTP of 99%. What this means is that £99.00 of every £100 wagered on that game is paid back to gamblers in the long run. 

What this doesn’t mean is that if a game has an RTP of 99%, you’ll only lose £1 for every £100 you bet – the payout is random and that means you could get a return of more or less than 99%. 

The very best casino slot payout apps have the highest RTP. We looked at countless slot apps and we came up with a list of the top three based on their RTP.

5 most popular casino app slot games 

There are thousands of slot games you can play at online casinos. It’s almost always the category with the biggest selection of games and some online casinos even have free slot games you can play. 

We spoke to members of the team to find the most popular slot games and came up with a list of the top five titles – there are some excellent slot games among the list and you may have already played a few of them. 

Slot game No. 1: Starburst 

Credit: YouTube

Casino payout (RTP): 96.1%

Probably the most well-known online slots game of all time, Starburst is a non-negotiable title for the best casino slot apps. It has five reels, ten paylines, and a maximum prize of 50,000x the money that’s been staked – it’s no surprise that Starburst is our most popular slot game. 



Slot game No. 2: Book Of The Dead 

Credit: YouTube

Casino payout (RTP): 96.2%

Sharing its name with the grisly text from Sam Raimi’s Evil Dead, Book Of The Dead is set in Ancient Egypt. It has five reels, ten paylines, and stakes ranging from £0.10 to £100 for a spin, making it a worthy entry to any casino app’s collection of slot games. 

Slot game No. 3: Thunderstruck II

Credit: YouTube

Casino payout (RTP): 96.7%

Even more popular than its near namesake predecessor, Thunderstruck II includes Thor's hammer, Mjölnir, five reels, and an enormous 243 paylines. One of the reasons that it’s one of the finest casino app slot games is the Wildstorm symbol – get five of these and you’ll get a whopping 7,000x jackpot. 

Slot game No. 4: Invisible Man 

Credit: YouTube

Casino payout (RTP): 96.4%

Inspired by a 1933 film of the same name, Invisible Man combines sublime graphics with a free spins feature to create one of the very best casino app slot games. It has five reels and ten paylines, giving you plenty of opportunities to win some money. 

Slot game No. 5: Bees Kneez

Credit: YouTube

Casino payout (RTP): 95.3%

Bees Kneez has a feel that’s both retro and lighthearted. The graphics are kitsch, bright, and use big friendly symbols. The game has five reels and 25 paylines, along with free spins if you match the right symbols – wild cocoons. 

Best casino slot apps for Android 

With two billion Android users worldwide, there are plenty of gamblers seeking a great slot app. While there are many great online casinos with superb apps, we’ve picked a trio of free apps that act as a great starting point for Android gamblers.

Android slot game series No. 1: Dragon Dollars

Dragon Dollars is a slot app collection that’s ideal for Android gamblers who want a gentle introduction to playing slots. Why? Because the game is for “entertainment purposes only. No real money can be won or lost.”

Android slot game series No. 2: Slots - Pharaoh's Way

Credit: YouTube

With 20 slots available upon download, Slots - Pharaoh's Way offers a great variety of games for Android gamblers. You get lightning reel stop, simple gameplay, and the chance to make some big (non-real money) wins – all of which makes its entry among the best casino slot apps for Android a no-brainer. 

Android slot game series No. 3: Casino Joy

Offering an introductory bonus of $20,000,000 of (fake) money, Casino Joy is one of the best ways to get a feel for slots. It’s free to download, free to play, and makes it to number three on our list of the best casino slot apps for Android. 

Best casino slot apps for iPhone

There are 900 million iPhones in the world, meaning there’s an enormous amount of gamblers who choose to use the platform for their gambling. We’ve narrowed down the countless options to give you the three best casino slot apps for iPhone. 

iPhone slot game series No. 1: Huge Win Slots

Credit: YouTube

Huge Win Slots gives you 10,000 free credits to commence your gambling, but that’s not the only great thing about this collection – it’s realistic, comes with tournaments, and allows you to play with your friends on Facebook. All in all, it’s an easy pick for our list of best casino slot apps for iPhone gamblers.  

iPhone slot game series No. 2: Slots of Vegas

Credit: YouTube

The name says pretty much all you need to know about this collection – what more could you want than being able to play the Slots of Vegas? Perhaps nothing, but what you get when downloading this free app is a welcome bonus of 50,000,000 coins. Combine that with a great range of games and Slots of Vegas is easily one of the top casino slot apps for iPhone betting.  

iPhone slot game series No. 3: MONOPOLY Slots

Credit: YouTube

Is it a novelty? Yes. Does it feature some awfully silly graphics? Of course. But these are the reasons to love MONOPOLY Slots. Why? Because those are the qualities of some of the very best slot games. That means this casino slot app for iPhone fans gets a big tick from us.  

Best casino slot apps for safety

How do you define what the best casino slot apps are for safety? It’s pretty simple really – you look to see that they’re regulated by globally recognised gamling organisations. 

So many of the best casino slot apps are being regulated by the same authorities, meaning that the list of safe options is enormous. With this in mind, we think that the most sensible way to decide if you’re using a safe casino app is to know the gambling regulatory bodies to look out for – you can see their logos below.
