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 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.
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.

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.
