Do some online casinos payout more than others?

When deciding which new casino sites to join, you’ll want to consider which have the best payouts.

Some casinos like to dazzle you by publishing details of their latest big winners while others hope to draw you in by promising lightning-fast withdrawals. Knowing which online casinos offer the highest slot payouts is probably the most helpful indicator.

You’ll sometimes find that casinos advertise their payout rates, which is a figure that indicates the average percentage that their games give back to their players. However, this can be misleading as the Return to Player (aka RTP) can vary significantly from game to game.

In addition, some game providers allow casino platforms and individual operators to alter the RTP of their games. This means that the sites that choose the higher RTPs offer players a better and fairer deal than those that choose the lowest RTPs. Mr Q is a great example; they always take the highest available slot RTPs for all their entire game library.

How does the RTP work?

Return to Player (or RTP) determines how much you stand to win from playing an online slot game. It’s listed as a percentage; 100% indicates you would win back exactly what you’d wagered. The higher the RTP, the more cash you should win back while playing over an extended period of time. For example, if a game has a 97% RTP, your theoretical return is £97 for every £100 that you spend.

Of course, it’s not a hard and fast rule. You may win more, or you may lose it all. However, the slot is engineered statistically to pay out that rate on average over time.

As we’ve just mentioned, RTP can vary from site to site, but this isn’t necessarily a way for casino operators to take more money from their players. For starters, online casinos don’t have complete control over the RTP of their games. Instead, the game manufacturers allow them to pick from a choice of fixed RTP percentages.

From the casino operator’s perspective, there are several reasons why a casino might wish to select a different RTP from the default one. Sometimes, they wish to see how new games are received, and this way they can get a feel for which version performs the best. They may also increase the RTP to raise the profile of previously under-performing games. On the other hand, they may lower the RTP if a popular slot is paying out too much and causing them significant financial losses.

But that’s enough of a sob story for the operators. We’re here to guide to the fairest of the casinos with the highest slot payouts!

NetEnt and Play n’Go are two of the best-known game developers that allow operators to pick their preferred RTP. Many casinos have games by these developers so always choose those that offer the highest RTP – simple!

No slot game will ever offer 100%; the industry would crumble! However, by playing slots that have an RTP of 97% or higher, you’re navigating probability well.

Some of the highest RTPs can be found in slots such as Monopoly Big Event (99%), 1429 Unchartered Seas (98.5%), and Blood Suckers (98%).

Get bigger payouts through bonusing

Bonuses can play a part in how much you can win. If you’re new to a site, the welcome bonus would be the first thing to look at, and if you’re a regular player at a certain casino, redeposit bonuses would be your first port of call.

You might think that the brands offering the biggest casino bonuses would give you the best chance of getting a decent payout. This isn’t always the case.

There are other factors to consider, such as what’s the bonus cap? Or how high are the wagering requirements? Being savvy and doing your research can help you find sites that can offer a better return. Just remember the golden rule – always check the T&Cs! We’re here to help!

Are you using expensive withdrawal methods?

To ensure that you keep as much of your winnings as possible, check whether you’re using a withdrawal method with no fees.

This list features sites that let you make fee-free deposits and withdrawals. However, there are some UK casinos that charge fees for using certain payment methods.

For instance, Videoslots and its sister site Mr Vegas let you make fee-free deposits using a range of popular payment types, but they do charge 1.95% for using Euteller. They also let you make one fee-free withdrawal per day, but any further withdrawals within the same 1-day period incur a £2.50 processing fee.

Surprisingly, Mr Green (which is owned by the same company as William Hill) charges £1 on all withdrawals of up to £100 and 1.5% on withdrawals of over £100. Jumpman Gaming sites (such as Matchup Casino) also charge you to cash out your winnings by taking £2.50 on every withdrawal, so it’s best to wait until you have a decent amount of money to withdraw.

At Grace Media casinos, deposits made using Boku (pay by mobile) incur a 15% fee.

In our experience, most online casinos that accept bank transfers as payment methods do not charge you directly for making deposits and withdrawals.

However, they often include a clause that warns customers that their bank may charge them for processing the payment.

The most popular payment methods that are accepted at UK licensed online casinos are listed below. As we’ve explained above, the fees that may be charged on each method can vary from site to site, so it’s best to check the banking policy at your chosen casino to help you decide which payment method is cheapest to use.

Why it’s important to play at a UK licensed casino

You should always play at a UK licensed gambling site, whatever you’re favourite games are.

Here in the UK, the Gambling Commission licenses operators and regulates them too. This means that all fully licensed gambling sites must adhere to extremely high standards regarding fair and responsible gambling as well as player protection.

There are many benefits to playing at UK licensed online casinos. These include the separation of players’ funds from the operator’s funds. If the casino were to go out of business, your money would be safe.

Customer complaints can be submitted to the Gambling Commission. So, if you ever feel that you’ve been treated unfairly or a casino isn’t performing to the standards that you’d expect, you can prompt the UKGC to investigate.

Licensed casinos must use independently tested and certified Random Number Generators to assure you that the games are fair.

At the end of the day, play it safe by only using UK licensed online casinos and don’t be lured in by the promises of big payouts at Wild West, non-licensed gambling sites.

Are the payouts on casino games rigged?

In a sense, but not in the way you might think.

All games are licensed by the Gambling Commission in the UK and have a set RTP. These games use RNGs (Random Number Generators) to create completely fair and random results that are tested to maintain their statistical RTP. So while each game has an average RTP that has been mechanically engineered, neither the casino nor the game developer can rig the results. They are completely random!

For online casinos to stay in business, the house has an edge on practically every game. This means that you could be lucky enough to land a big win or two, but over the longer term, the casino is likely to end up with more of your money than you.

Which casino game pays out the most?

If you want to discover UK casino sites with the best payout, it’s good to know which games pay out the most.

It’s best to pick games that offer an RTP of at least 95%, and preferably 97% or more.

With table games, you’ll either see RTP or house edge mentioned. The house edge defines what advantage the casino has, and it can be anywhere between 1% and 5%.

If you enjoy table games, look out for Single Deck Blackjack (99.91%, Ultimate Texas Hold’em (99.47%), First Person Baccarat (98.94%), and European Roulette (98.65%).

If you prefer to play online slots, keep your eyes peeled for Mega Joker (99%), NetEnt’s Blood Suckers (98%), and Big Time Gaming’s White Rabbit Megaways (97.77%).

Do the casinos not on GAMSTOP pay out more?

Online casinos that are not part of the GAMSTOP scheme are unregulated in the UK and should not be engaged with. These sites are unlicensed and therefore do not appear on our site at all. Stay away from non-regulated casinos. They’re illegal and unsafe!

Can casinos change the RTP of their slot games?

Some, but not all online casinos, have been known to alter the RTP of their slot games, especially in recent times.

This is only possible with games that are made by selected software developers. This gives the casinos the opportunity to choose the RTP that suits their business models the best. We expect to see more do this in the UK with the upcoming gambling duty increase in April 2026.

One of the major software developers that allows certain online casinos to choose from a sliding scale of RTPs is Play n’Go. Others include NetEnt, Red Tiger Gaming, Pariplay, and StakeLogic.

Do all withdrawal methods come without a fee?

No. While the most popular casinos usually allow you to make withdrawals without incurring administration fees, some operators do charge you to withdraw. Some charge for all withdrawals, while others allow you one free withdrawal per day with the option to submit further withdrawal requests at a cost. There are also casinos that charge you for using certain withdrawal methods.
