How to find an online casino with the highest payout percentage

In order to find the percentage that online casinos payout, we need to investigate what games are offered by the casinos. Major casino game manufacturers, such as Microgaming and Netent, offer a 96% return on slots. However, this is an average value, which means that there are games that offer slightly lower percentage returns, as well as games that offer higher returns to players. Before we get into the more complex topic of calculating the payout percentage a casino offers, let’s first dive deeper into what the topic of RTP.

What is RTP (Return To Player)?

RTP is the percentage paid to a player on average in a casino game. Slot machines have RTP’s of around 96%, but there can be a lot of variation between machines, and even from one casino to another. Local casinos that don’t offer online games tend to have worse RPT percentages because they have to pay for staff, rent and other costs that online casinos don’t have. However, the RTP can also vary between online casinos, as some games, like progressive jackpots, have both a casino-specific portion of a jackpot as well as a worldwide one. This can mean you can find a better RTP at some casinos compared to others.

For example: If you play on an online slot machine with 96% RTP and place a €100 bet, you’ll win €96 on average. So you lose €4 per spin on average.

RTP is an average calculated on the basis of thousands of spins, which means that you are unlikely to win exactly €96 in each game session. See each percentage under 100 as the earnings of the casino. The rest is divided among players as they play, with some doubling or tripling their money on a spin while others don’t win anything. This happens randomly, so it’s more likely for you to not win anything or double your money in most slots than it is to win exactly 96% every time. If you always won less than your bet then the game wouldn’t be any fun, would it?!

Best payout online slots 2021

Knowing the RTP of a given online slot will give you a better picture of your chances of winning. The higher the RTP, the longer your session is likely to last and the more you’re likely to win. For this reason, it’s worth knowing the best online payout slots, so that your sessions last as long as possible and you have the best chance of winning.

  • Mega Joker – Mega Joker (Netent) has a 99% RTP and is the best choice among all the online slots if it’s solely a high RTP you’re after. This game has 5 reels, a progressive jackpot, and a Super Meter feature. Mega Joker boasts a vintage design and uses classic symbols like bells and different kinds of fruit. It’s a high-variation slot, but we’ll get into what that means for your chances of winning a little later on in the post.
  • 1429 uncharted seas – 98.6%
  • Blood suckers – 98%
  • Devil’s delight – 97.6%
  • Starburst – 96.1%

RTP in other casino games

Of course, in the best online casinos in the UK, you’ll also find other online casino games to enjoy, and not be limited to just slots. Roulette and blackjack are just some of the many other games online casinos offer their users. These games are also available in the live casino, which can make them even more interesting to players looking for a more social experience. Wondering what the average RTP is on these traditional casino games, as well as what the best payout is? We’ve compiled an overview of these games for you below.


There are usually 3 types of roulette in online casinos. Each type of casino game has a slightly different RTP due to a varying number of zeros on the wheel. Let’s take a closer look at the differences in RTP below.

  • American Roulette – 94,74%.
  • European Roulette – 97.30%
  • French roulette – 98.65%

As you can see, French roulette and European roulette have the best payout when compared to American roulette, with French roulette returning the most of all three. Since the experience is much the same with these different types of roulette, we always advise players to go for European or French roulette as opposed to American roulette on order to enjoy the best RTP possible.


The return percentage is different in different types of blackjack too:

  • Blackjack (Three-seat) has 95.38%
  • Classic Blackjack 99.41%
  • Premium Blackjack 99.67%

The main difference when it comes to blackjack is that knowing how to play the game can give you far better odds. In reality, the RTP of blackjack is so high when you play well. However, if you don’t know the game or make a mistake, your chances of winning could be as low as 70% or less. The fact that your skill makes a difference in your odds is what makes blackjack so much fun. If you’re lucky and know what you’re doing, it’s by far one of the best returning games available in casinos.

High-variation vs low-variation slot games – What’s the difference in RTP?

Both high-variation slots and low-variation slots can have a very high RTP. However, there’s a big difference in how the winnings are paid out between these different slot games. Low variation slots may have prizes ranging from 50% to 200% of your wager, with just a small chance of not winning anything on a spin. This results in lots of smaller prizes, which means you can bet higher amounts and continue to play for a long period of time because there’s a big chance of winning something, even if it is slightly less than your wager.

Slots with high variation may have prizes ranging from 50% to 20.000%, but they have a higher chance of you not winning anything per spin. This means that you have a higher chance of winning 2x or even much more on a spin, but there’s just a smaller chance of winning something overall. So, you have to spin more times on average in order to win something, but when you do win, you’ll generally win higher amounts. These often offer the best payout to players when they get lucky, but can also make you blow through your budget a lot quicker if you’re not.

The main reason this is important when talking about RTP is that your reason for wanting a high RTP influences whether a high-variation or low-variation slot is best for you. If you want to win big, slots with high variation are a better option. You can always lower the amount you wager per spin to keep playing for longer. If you want to play for a long time and just want to enjoy the slots, then low-variation slots can be a good option. This way you can win more often and wager higher amounts without the risk of losing everything all too quickly.

RTP – Normal slots vs jackpot slots

When looking for the best RTP slots as well as the best returning casino, you need to understand the different between normal slots and jackpot slots. Both of these types of slot machines can offer a high RTP percentage, but just like with high-variation and low-variation slots, there’s a difference in how the RTP is divided.

The RTP percentage of jackpot slots devotes a large percentage to the jackpot. This can be 5% or 15%, so it’s important to check the numbers before you start playing. The chance of winning the jackpot is obviously minuscule, so the RTP excluding the jackpot is important to know. Many jackpot slots, even if they are low variation and you can still win often even without considering the jackpot, will have RTP percentages under 90%.  This means than if you want to play for a long time, they’re not the best slots to go for.

Obviously, you need to consider that this is the risk you take when choosing a jackpot slot. The large jackpot makes the game exciting and it’s one of the reasons why they’re so popular. If you want to try to win the jackpot, then go for it!

The casino games to play for the best payout

Trying to find the best payout casino games can be a challenge, especially when you start to consider other factors like progressive jackpots and skill. We can’t tell you exactly which games are going to offer you the best returns, but there are a few tips we can give you to help you find the games that are going to get you the best results. Bear in mind that the most important part of playing slots and other casino games is having fun. It’s a form of entertainment, so if you personally feel a game with a lower RTP is more fun to play, just go with that. However, if you want your games to last as long as possible, here are some tips:

Avoid games with progressive jackpots

The reason you should avoid games with progressive jackpots when you want your games to last as long as possible is that a huge percentage of the RTP consists of the jackpot. Sometimes as much as 15-20% of the RTP consists of the jackpot, which means if you exclude the tiny chance of you winning the jackpot, the real RTP is 75-85% instead of the mentioned 95%+.

 Go with low wagers on high-variation slots

If you’re playing slots with high variation, then wagering just small amounts of your total budget for that day will ensure you have a better chance of playing for longer periods of time. Wagering less than 1% of your budget will mean you can spin at least 100 times, which is usually enough to win a few nice prizes.

Know what you’re playing

Blackjack can offer you the best RTP in a casino if you really know what you’re doing. Poker is another game that requires some skill, and there are online casinos that host tournaments on occasion too. If you enjoy these games and know how to play them, you can enjoy a far better RTP than with other games.

Use bonuses and free spins

There’s no easier way of raising the RTP you’re set to get than using bonuses and free spins. Since you play for free, these bonuses instantly raise your chances of winning, since you can spin more often with the same budget. Always make sure to check the terms and conditions before applying for a bonus to ensure that you know what you need to do to cash out.

Can you increase the RPT by using a special technique?

There aren’t any hacks or tricks that are going to improve your chances of winning. That being said, by knowing the game, for example when playing blackjack, you can prevent your chances from being lower than they should. Also, by spreading your funds over a larger number of spins, you can make sure you’re closer to the average RTP, which can also increase your chances of winning something. That being said, these techniques prevent you from decreasing your chances of winning, instead of actually increasing them. Apart from cheating, like counting cards (which has been made near-impossible over the past decade), there’s not much you can do. It’s best to just enjoy the games responsibly instead of trying your best to actually make money from gambling.

The payout you should realistically expect in online casinos & the amount you’ll likely walk away with

Even the best returning casino isn’t going to guarantee that you leave the casino with anywhere near the money you deposited, let alone with more. It’s important we understand that casino games, regardless of the RTP, are there for fun. It’s great fun to dream about winning the jackpot, as well as to play casino games to pass the time, but it’s important we don’t get carried away. Chasing the best RTP and the best bonuses can help you enjoy games for a little longer, but it’s not going to turn your virtual trip to a casino into a profitable business venture. Always gamble responsibly and when the fun stops, make sure you stop too. They’re there for our entertainment!

The reason RPT differs from one online casino to the other

RTP is often monitored by online casinos to ensure the games are still functioning properly. However, RTP does vary between casinos. This can be important when searching for the best payout casinos, but can actually be completely irrelevant too. A portion of this difference in payout is purely down to chance, but another portion is a true difference in RTP. We’ll cover both of these and explain the difference between them below:

True difference

There are two main scenarios that cause a real difference in the RTP. The first is the difference between online casinos and physical casinos. Not only can the bonuses influence your chances of winning with a certain deposit, but also the costs that normal casinos make can influence the RTP. Online casinos can be profitable at very low RTP percentages, but physical casinos can’t. You pay a little extra for the experience, as they have to pay for their staff, the rent and for the various facilities, food and drinks.

There can also be a difference when it comes to jackpot slots. Some jackpot slots have a worldwide jackpot which is topped up by a casino-specific jackpot. Say the jackpot is 5% of the RPT, 4% may go towards the worldwide jackpot and 1% goes to the casino-specific jackpot. Within a few months, this may mean that the RTP is quite a bit higher in a larger casino than a smaller casino, since the winner of the jackpot will win substantially more. In reality, the difference is usually small but it’s interesting to think about.

Pure chance

If a game has paid out a 96% RTP to date but is actually marketed as a 97% RTP slot, it simply means that players have been unlucky. If it’s the other way around, then players have been lucky… At the end of the day, random number generators are, well… random! This means that there’s always a chance that the percentage that is actually paid out is slightly less or slightly more. This doesn’t influence your chances of winning though, which is important to consider.

Highest Payout Online Casino UK

When looking for the highest payout online casino in the UK you must take into account the games offered by the operator, as well as the other variables we’ve spoken about in this article. The game in question is going to determine your RTP and not so much the casino itself. It’s also important to consider that the RTP is an average number, and doesn’t mean you always get this amount back. As you could read above, online slots offer up to 99% RTP, which makes them one of the best returning games. In blackjack, 99.67% is the maximum which makes it the best returning game by far. That being said, you do need to know what you’re doing in order to enjoy this high RTP.

Remember that the gambling site always has an advantage over the player. This means that in the long run, you will always lose money. The online casino is a business, gambling is entertainment.

🍇 What casino has best slot payouts?
