What Is RTP and How Does It Affect Payouts?
To put it simply, RTP (or Return to Player rates) are completely theoretical percentages built into every casino game by the software provider. While it may be theoretical, it doesn’t make the RTP any less important when choosing a game. The higher the RTP, the better the chance of winning while playing.
The RTP should not be confused for the volatility of a casino game which determines how payouts take place, rather than when they take place.
There’s a bit of math that goes into determining what the RTP of a slot or casino game really is. Usually tested over 1 million or more spins, the RTP takes the total amount returned to players via wins and divides it by the total amount bet by players.
For example: If a game pays out €9000 for every €10,000 that is bet, the math will determine that the RTP percentage is 90%. This would be considered a low RTP casino game.
It’s important to note the RTP of any game can only be verified by a trusted third-party company such as eCOGRA, GLI, TST, or iTech Labs. Most online casinos worth their salt will have their games tested on a regular basis to ensure that you’re experiencing a fair way of playing with the best chance of winning.
Casino Bonuses for Best Payouts
We all know that playing casino games should purely be for entertainment but it’s always a great feeling when a casino game pays out as you play. One of the best ways to experience casino games is by claiming a bonus but not all bonuses are great for making the most of the high payout rates offered by casino games.
Here are 3 of the best bonuses you should keep your eyes peeled for when searching for an online casino to visit.
Low Wagering Bonuses
Being able to play casino games with high payout rates while using a low-wagering bonus is a good idea. Bonuses with low wagering requirements mean that you can claim a big win and not have to play through it over and over in order to make a withdrawal. Search for low wagering bonuses and you could easily take home a large portion of what you win thanks to a high payout casino game.
No Wagering Bonuses
Another major player in the bonuses game is the No Wagering Bonus. This means you can claim a bonus, spend it on a game with a great payout and not have to wager your winnings to make a withdrawal. Hands down, these are the best bonuses to enjoy at any online casino.
Uncapped Winnings Bonuses
Many online casinos place a winning cap on their bonuses. Especially bonuses that don’t require a deposit or that provide free spins on slots. However, this can place a real damper on enjoying a high payout slot or casino game. Find a casino with no cap on winnings and you could take home a handsome sum of cash if Lady Luck is on your side.
UK Casinos with Highest Slot Payouts
The average RTP for online slots at UK casinos ranges between 85% and 96% with the latter becoming the norm. However, progressive slots are often found to have the highest RTP rate with some climbing as high as 99%! Here are 5 slots with super high RTPs.
- Mega Joker by NetEnt: Up to 99% RTP
- Jackpot 6000 by NetEnt: Up to 98.8% RTP
- 1429 Uncharted Seas by Thunderkick: 98.6%
- Bloodsuckers by NetEnt: 98% RTP
- Big Bad Wolf by Quickspin: 97.4% RTP
Highest Payout Roulette Games
Depending on the variation of roulette you choose to play at online casinos, the RTP could differ. For the most part, the European roulette version of the game is the most popular and is more widely available. This version of roulette tends to have an RTP of 97%. Here are 5 roulette games with high RTPs for when you’re ready to start playing.
- Premium French Roulette by Playtech: 98.65% RTP
- Roulette French La Partage by Play’n GO: 98.65% RTP
- Roulette Classic by Playtech: 98.65% RTP
- Premier Roulette Diamond Edition by Microgaming: 97.70%
- Penny Roulette by Playtech: 97.70% RTP
Highest Payout Blackjack Games
Blackjack is known to have one of the highest RTP percentages of all the online casino games available today. With only a slight variation, the RTP tends to sit between 99% and 99.8%. Here are 5 of the best options to enjoy at online casinos.
- Classic Blackjack by Microgaming: 99.91% RTP
- Blackjack Switch by Playtech: 99.87% RTP
- Red Queen Blackjack by 1×2 Gaming: 99.80% RTP
- Vegas Single Deck Blackjack by Microgaming: 99.69% RTP
- Blackjack Multihand by iSoftBet: 99.65% RTP
Highest Payout Baccarat Games
Much like blackjack, baccarat has a very high RTP as a standard. Games of skill tend to have higher RTPs due to the fact that they need more than just a little luck to land a win. By ‘working’ for your win, the games have a higher RTP to keep players entertained for longer. Take a look at these 5 baccarat games with high payouts.
- Classic Baccarat by Real Time Gaming: 98.94% RTP
- Baccarat by Playtech: 98.94% RTP
- Baccarat Professional Series by NetEnt: 98.94% RTP
- Punto Banco by Red Tiger Gaming: 98.92% RTP
- Hit Me Baccarat by Eyecon: 98.92% RTP
UK Casinos with No Cap on Winnings
To get the most out of your favourite casino game with a high RTP and the best payout, finding the right online casino is key. We recommend finding an online casino that offers free spins and no maximum on winnings from those spins. However, we know that this is a tough task.
By playing at a UK casino that offers no cap on winnings, you can play a game with a high payout rate, potentially win big and not be penalised for it.
We know that it’s not easy to find an online casino that offers this experience but it’s not impossible!
PlayOJO Casino is a great choice for those who want to experience no cap on winnings. Not only can you enjoy 50 free spins with your first deposit, but there are also no wagering requirements, and no maximum amount set on how much you can win!
Add to that the fact that this top-rated casino is fun, colourful, and hosts thousands of casino games, and you’ll find yourself in good hands when playing at PlayOJO.
Fast Payout Casinos vs Best Payout Casinos
They may sound similar but playing at a fast payout casino and a casino that offers the best payouts is very different.
The best payout casinos are home to casino games that give you the best possible chance of winning (or receiving a payout). With high RTPs and great games, playing at a best payout casino could be your ticket to landing a big win.
If you’re searching for a fast payout casino, then that means you want your winnings paid out in a flash. These online casinos are known for providing super quick withdrawals to those who simply can’t wait. You can take a look at our guide to the UK’s fastest withdrawal online casinos for more information.
What is RTP?
RTP is the term used at an online casino to describe the Return to Player rate of a casino game. Essentially, it’s a percentage of all the money wagered on a casino game that will be paid back to players over the lifetime of the game. With regards to a casino, the better the RTP rate, the better the games at the casino tend to payout over time. It’s not a guarantee but playing at a UK casino with a high RTP means there could be more chance of landing a lucky win.
Is the RTP the same for all online casinos?
No. Depending on the games featured at the online casino, the overall casino RTP will differ. Always take a close look at the range of games on offer to determine if an online casino will have what suits your needs and playing style.
How is RTP calculated?
The Return to Player rate of an online casino slot (as an example) is usually calculated at over 1 million spins. This can vary from game to game, but the principle remains the same. The RTP states that the amount of cash bet on a game is divided by the amount it pays out. For instance, if players bet €100 on a slot and it has an RTP of 95%, it will pay out €95 over 1 million spins. RTP can also be calculated by stating that the same machine holds on to 5% for the house. Over time, this is how the house makes money. These numbers are completely theoretical and while choosing a game with a higher RTP gives you a slightly better chance of winning in the long run, it is still completely down to luck.
Which UK Casinos have the best payouts?
We have a number of fantastic online casinos available that all have top payouts. Take a look at our list of recommended casinos and find out why you should visit sites such as Pink Casino, and BGO!
Can I trust a casino’s RTP to be legit?
In order for RTP rates to remain fair, there are certain regulatory bodies that insist on tracking how low software providers are allowed to set these rates on casino games. However, you can trust that a casino’s RTP is legit when they welcome testing from third-party agencies such as eCOGRA, GLI, TST, and iTech Labs.
