Best Payout Slots

Best RTP Video Slots

Here is a selection of the highest RTP slots you can play at UK online casinos.

What Makes a High Paying Slot Game?

The return to player (RTP) is the percentage of all money wagered on a slot game that is paid out back to players. The higher the RTP, the more often the slot pays out on average. So if a game has an RTP of 96%, you could, in theory, expect to get back 96p of every £1 you wager over an extended period of play.

However, RTP isn’t quite as simple as that. The average is calculated based on the wagers all players put into a game over an infinite number of spins. This means you can easily be winning back more or less than the RTP at any one time. For this reason, it’s best to use the RTP as a rough estimate of what you could win, and don’t be surprised if your actual returns are some way off.

Most online slots have an RTP of 94% to 96%, so any game with an RTP of 97% or more would be considered a high payout slot. However, these RTPs aren’t always set in stone – some slots’ RTPs change depending on how much you wager. For example, in certain titles, you have to bet the maximum stake with each spin in order to activate the highest possible RTP.

As a general rule, it’s a good idea to select a slot with a high payout percentage. Most online slots have an RTP of 94% to 96%, so any game with an RTP of 97% or more could be considered among the best paying online slots. However, these RTPs aren’t always set in stone – some slots’ RTPs change depending on how much you wager. For example, with certain titles, you have to bet the maximum stake with each spin in order to activate the highest possible RTP.

When choosing the best slot sites for winning, it’s a good idea to check the RTPs of their games before you sign up. UK-licensed casinos are legally required to clearly state this information, making it easy to pinpoint which ones have the best online slots payout percentage.

How to Find a Slot Game’s RTP

Luckily, finding out the RTP of online slots is relatively easy. All licensed UK casinos and software developers must make game RTPs easily accessible in order to ensure transparent gaming. Once you load up a slot, simply click on the ‘i’ or ‘?’ icon to find the RTP either stated alone or as part of the slot’s paytable.

Slot Variance/Volatility Explained

Another important element to consider when taking a look at low and high RTP slots is variance, or volatility, which refers to the size and frequency of online slot payouts. Low variance means small prizes that payout often, while high variance slots payout less frequently are more likely to hand out sizeable returns when they do. These high variance titles could be regarded as the best slot games for those who have larger bankrolls to play with, those who like to hit the slots for occasional sessions, or simply enjoy the buzz of playing at higher risk for potentially higher rewards. On the flip side, low variance games are popular with players who have smaller bankrolls or who like to be able to play extended, lower risk sessions.

Progressive Jackpots

If progressive jackpots are famous for their life-changing payouts, then the titles funding them must be the best paying slots, right? Well, quite possibly, but only if you win the elusive jackpot, which is easier said than done.

Let’s look at an example. Microgaming’s Mega Moolah holds the title for the biggest ever online slot payout — one very lucky player bagged more than £16,000,000 on this game. You might think that this makes Mega Moolah the ‘highest paying slot’, but this title has an RTP of just 88.12%. That’s pretty low on the RTP spectrum. If you get lucky enough to land a rare win, it’s likely to be a bigger prize. However, on average you’re far less likely to land some returns on Mega Moolah than on the best RTP slots.

A progressive jackpot can be standalone, which means it is individual to one game or pooled between games. In these cases, wagers on multiple titles contribute to the prize fund, so top prizes tend to grow larger and faster.

Top 5 NetEnt Payout Slots

Founded in Sweden in 1996, NetEnt has produced some of the world’s most popular and best paying slots. Let’s take a quick look at five of their best payout online slots.

Mega Joker – 99% RTP

A classic-style game with two sets of three-reel slots, Mega Joker launched in 2013 and has become a fan favourite thanks to its retro, fruit machine feel and remarkably high 99% RTP.

Jackpot 6000 – 98.8% RTP

Böb – The Epic Viking Quest for the Sword of Tullemutt: 98% RTP

The title itself is epic in length, and this 2015 five-reeler lives up to the billing with its plethora of helmet, battleaxe, and longboat symbols, not to mention the bonus game where players hunt down hidden swords for cash rewards.

Kings of Chicago – 97.8% RTP

Launched in 2011, Kings of Chicago changes things up by dealing out cards rather than spinning symbols. It’s still very much a slot game, though – a familiar five-reeler which pays out depending on which poker hands come up.

It may look small with its 3×3 reels, but Supernova makes up for that with cool, sci-fi graphics and a great soundtrack, as well as a multiplier feature which is set on some extra reels. Released in 2017, it still shines brightly in Microgaming’s ever-growing galaxy of slots. 

Couch Potato – 97.05%

Best Paying Mobile Slots

Want to play the best RTP slots while on the go? All the best online casinos have mobile-friendly websites, so you can do exactly that when you play at our recommended slots sites. The top slots developers like NetEnt, Microgaming and Playtech all optimise their games for mobile play, meaning you can enjoy smooth spinning when you play on your mobile or tablet.

If you want to enhance your mobile slots experience, download a casino mobile app. A whole host of the UK casinos have native apps that are free to download on Android and iPhone, and come with a number of benefits. For starters, mobile apps store data on your device, rather than relying on slow web servers, so you can enjoy faster gaming. Plus, if you turn on push notifications, you’ll always be kept in the know on the latest promotions and hottest new slots releases.

Choosing a Reliable Casino

Playing the best RTP slots is all well and good, but it’s important to play at a reliable casino that will pay out if you do land a win. There’s only one way to do this: choose a UK Gambling Commission (UKGC) licensed casino. The UKGC regulates casinos to ensure a number of things, including account security and fair gaming. This means that all the high paying slots you play at licensed casinos have accurate RTPs and use random number generators (RNG), ensuring each spin is random and unbiased. The UKGC also ensures that online casinos pay out within the stated timeframes. None of this is guaranteed if you choose an unlicensed site.

Every casino site featured on TopRatedCasinos is fully licensed and regulated, so you can rest easy when you choose one of our recommended casinos. Want to double-check that a casino is licensed? Simply scroll to the footer of your chosen site where you’ll find the UKGC logo and the site’s licence number, or alternatively take a look at the regulator’s public register.

Slots Bonuses

Online casino bonuses are a great way to boost your bankroll, either through cash tokens or free spins. When you sign up to a new online casino, the bonus on offer could be a deciding factor in where you end up spinning the reels, and there are a few factors to consider for the major bonus schemes available when you’re making your decision.

Matched Deposit 

This is the most common welcome bonus at online casinos, seeing the operator match your first deposit by a certain percentage and up to a certain amount. For example, 100% up to £100 would see the casino provide a maximum of £100 in additional funds, meaning you can deposit £100 and have £200 in your on-site wallet to play with. These bonuses are typically tied to wagering requirements, meaning you must play the value of the bonus a certain number of times before you can withdraw any winnings made using the bonus funds. 

Free Spins

Free spins are the quintessential slots bonus, commonly offered in-game, as a sweetener for another bonus, or as a standalone bonus in their own right. If you’ve racked up some free spins as part of your online casino’s bonus scheme, these spins may be restricted to particular games, or they may be subject to a winnings cap. The biggest factor here is in-game restrictions, as you’re unlikely to be able to use free spins offered as part of a welcome bonus on high RTP slots — chances are, you’ll be limited to playing something like Starburst or Gonzo’s Quest, which are excellent titles nonetheless.

Time limits are commonly used too, with your spins typically needing to be spun within a set timeframe. Spins won in-game aren’t subject to such restrictions, leaving the focus on trying your luck a few more times without wagering your cash to do so.

Wagering Requirements

Not exclusive to matched deposit bonuses, wagering requirements can be attached to practically any bonus or promotion offered by an online casino. With wagering requirements in place, you must wager the value of your bonus a set number of times before the online casino will allow withdrawals. The average is 35x, with anything above being considered high wagering, and anything less qualifying as low wagering. The amount that must be played before making withdrawals can be calculated in one of two ways when the bonus is straight cash or has a clear monetary value:

1. £100 (bonus) x 35 (wagering requirements) = £3,500 (total that must be staked)
2. [£100 (deposit) + £100 (bonus)] x 35 = £7,000

As you can see, the calculation used can make a huge difference. Be sure to check the bonus terms and conditions to make sure you understand how the wagering requirements will be calculated.

If wagering requirements are in effect for free spins, the calculation is typically made using the value of your winnings from those free spins.

1. For example: £50 (winnings) x 35 = £1,750.
