Of course, extra slots are being added to casino sites all the time, so check back regularly to make sure our list of the best online slots payout percentage UK players can find hasn’t changed.
How to Find the RTP of a Slot Machine
Finding the RTP of a slot machine is generally pretty easy. This is because every casino has to show the payout percentages to players, and these are usually found on a dedicated page. We’d always recommend looking at this page first before you play a slot machine, just to ensure you’re not playing a game with a ridiculously low RTP.
Some gambling sites hide their information on payouts deep within their site though, making them tough to locate. If you can’t find the information you need at your chosen casino, just Google the game’s payout percentage instead. There are plenty of sites that will have the information you need.
Progressive Slots Explained
Progressive slots generally have the biggest jackpot prizes around. This is because the top prize keeps on building up as more and more people play the game. When a player manages to win this progressive jackpot, it will reset back to its minimum amount, before starting to build up all over again.
Many people are really attracted towards progressive games, thanks to the big prizes. We’ve got news for them though: progressive jackpot slots generally have the lowest RTPs around. While you could win millions, you’ve got a much better chance than other games of not winning anything at all. Whether you still choose to play progressive jackpot slots is completely down to the type of casino player you are.
Playing Real Money Slots on Mobile
If you want to play slots using a mobile, there’s no need to worry. This is because the best payout online slots have the same RTPs, regardless of how you play them. So, whether you gamble using a desktop or a mobile, you’ll have exactly the same chance of winning. Mobile players will also find that the bonus game features found on slots are exactly the same, plus they’ll find that the graphics are still very good. Basically, when you have a few spins using your mobile, you’ll be treated exactly the same as desktop casino players.
It should also be mentioned that mobile slots players can also receive the same bonuses as desktop players, including welcome bonuses. What’s more, it isn’t just slots on offer to mobile players, as they can also play table games, live casino games and more. This will apply to pretty much everyone, regardless of the mobile device they choose to use.
Most Popular Slots Software Producers
There are many online slots software providers out there, however the top three are definitely Microgaming, NetEnt and Playtech. They produce some of the slots with the most recognisable themes, as well as many slots with absolutely gigantic prizes. What’s more, they usually have stunning graphics and the gameplay is incredibly easy.
Unfortunately, the best looking and most popular slots aren’t always the best payout online slots. This is why we’d encourage you to also look at the slots from smaller software providers too. These smaller software providers are often trying to get a foothold in the industry, therefore they deliberately produce some of the best payout online casino games. This allows them to attract new players as quickly as possible.
Play the Best Slots at Online Casinos Today
Now you know about the slots with the best online casino payouts, you’re ready to head to one of our recommend casino sites and start playing. Hopefully you’ll be able to have some luck when you play one of the best payout online slots featured further up this page!
