How We Find The Best Payout Casinos Bonuses

Our team of iGaming experts has researched and assessed top platforms to bring you a top five of the best online UK casinos with high RTP (Return to Player) percentage. This figure shows the ratio of wins to wagers. For example, if a site’s RTP is 95%, a site will pay back 95% of stakes in wins over a long period of time. However, keep in mind that the outcome of each game is random. Therefore, you could win big with a single spin of a progressive slot game or go on a long losing streak. To clarify, the RTP is not an indicator of how much you will win in a single session. Instead, it’s the overall payout rate of the game over a time and applies to many different gaming sessions.

Top Five Payout Casinos

The following online gambling platforms are, over the long run, the highest payout online casinos in the UK.

1. Skol Casino

With an RTP of 97.85%, Skol Casino is the king of high payout online casinos in the UK. However, it boasts much more than a low house edge. This online gambling site has top games from the best software providers, rapid withdrawal times, and excellent promotions - available to new and existing players.

2. Fun Casino

3. Casumo

Casumo casino slides into third place with a decent RTP of 97.27%. Yet despite this decent stat, this online gambling site prefers to attract players with its stellar gaming lobby that includes over 2000 video slots, live table games, jackpots, and sports betting options. View our Casumo review

4. 888 Casino

5. Jackpot Mobile Casino

Players join Jackpot Mobile Casino because of its wide variety of slot machines, table games, and live dealer options - all of which work flawlessly on mobile devices. Check out our Jackpot Mobile Casino review to learn more.

How Online Casino Sites Available in the UK Calculate Their RTP

Independent auditing firms, such as eCOGRA, GLI, and iTech Labs, verify the RTP of games and casinos in the UK. Sites calculate their RTP rates by considering the RTP percentage of all their individual games and bonuses. Consequently, the best payout online casinos in the UK have excellent promotions available, such as no deposit with bonuses low or zero wagering requirements. This is because gamers who have effectively paid nothing or very little to unlock free wagers can receive payouts disproportionally higher than what they paid in.

Top Five Online Casino Games with the Highest Payouts

The payout percentages of casino games vary. That said, traditional table games generally have the best payout percentages.

1. Blackjack

As Blackjack has an average payout rate of 99.5%, it is the best payout online casino game - hence why many online casinos don’t let stakes placed on this card game contribute to wagering requirements of bonuses. Although there are many versions of blackjack, the RTP is similar. Yet keep in mind that side bets like insurance have far lower RTP rates.

2. Low Volatility Slot Machines

The RTP of online slots varies from 85% - 99%. However, low-volatility titles, such as Ugga Bugga by Playtech (99.07% RTP) and Mega Joker by NetEnt (99% RTP), have impressive return to player percentages.

3. Roulette

Whether online or in-person games, roulette has a shared high RTP (around 96%). However, some games boast a house edge as low as 1.36% (RTP 98.64%) if the En Prison or La Partage rule is applied.

4. Video Poker

This popular online casino game has an average payout rate of 95.43%. Yet some video poker games can have a low RTP, so always check this before wagering.

5. Baccarat

Baccarat is a high-stakes game with a 98,91% RTP on average. Still, be aware that the RTP for the Banker bet is slightly higher than the RTP for the Player bet, and the tie bet wager is the lowest.

Best Payout Online Casinos UK FAQs

What is the house edge?

Ever heard the expression “the house always wins”? This is referring to the mathematical advantage that a casino has over players in a game - known as the house edge. It is shown as a percentage and represents the amount of money that the casino can expect to earn/payout from each bet over a long period of time. For instance, if you play a game with a 95% RTP, the house edge is 5%. Therefore, the longer you play, the more the “house” makes.

What casino games have the highest payout rate?

Traditional table games such as poker, roulette, and baccarat have a higher payout rate compared to other games. However, some slot games also have a high RTP. For instance, Ugga Bugga by Playtech has an RTP of 99%.

What is a casino game payout rate?

A casino game payout rate shows how much the game pays out in relation to the total amount of money wagered. However, it's important to note that the RTP is calculated over a large number of wagers. Therefore, to reach the average RTP reported, you would need to place hundreds of thousands of bets.

What's the difference between volatility and RTP?

Volatility, also known as "variance," refers to the risk level of a game. A game with high volatility has a higher risk of losing money but has the potential for higher payouts. A game with low volatility has a lower risk of losing money, yet it gives you smaller wins. RTP (Return Top Player), however, refers to the percentage of money that is returned to players over time. RTP is shown as a percentage. For example, a 97% RTP means that for every £100 wagered, £97 will be returned to players over time - on average. Put simply, Volatility is the risk level of a game, and RTP is the percentage of money that is returned to players over time.
