Highest Payout Online Casinos UK 2023

What are Payout Percentages in Online Casinos?

Payout percentages refer to the theoretical percentage of the overall wagered money that a casino game will pay back to players over time. Each game’s payout rate contributes to the overall payout percentage of an online casino, whether we talk about slots, blackjack, or roulette.

What is RTP, and how can it create better payouts?

Payout percentages are also known as “RTP”, which stands for “return to player” and refers to the payout percentage built into a casino game. It is generated by the game’s random number generator (RNG) software to pay out winnings at the rate advertised.

For example, if a slot has an RTP of 95%, it means that for every £100 wagered on the game, £95 will be paid back to players as winnings over a long period of play. The remaining £5 is kept by the casino as profit.

RTP directly impacts your long-term payouts.

The higher the payout percentage, the lower the house edge, and the better the odds for players. That’s why you should be comparing the payout percentages of casinos and their offered games.

Even small RTP differences between games make a significant impact over many bets. For example:

• Slot A has 95% RTP
• Slot B has 97% RTP

Over 100,000 spins, Slot B will pay out £2,000 more than Slot A on average.

So, you should pick the highest RTP to boost your payouts.

RTP does not influence individual spin outcomes

• For slots, the RTP usually accounts for millions of spins over time.
• For table games it represents the mathematical return to perfect play.

Many factors influence RTP rates, like the game rules, bet range, hit frequency, and bonus features.

Can online casinos modify game RTPs?

Online casinos can modify the RTPs of certain slot games. For example, some progressive jackpot slots by IGT may have custom RTPs. However, generally , the best payout online casinos keep them high to attract players.

Despite RTP percentages being slowly a thing of the past in the UK industry, players are still using it to compare theoretical odds in games and even the UKGC itself monitors live RTPs to compare with the advertised values.

KingCasinoBonus Defines a High Payout Online Casino

A high-payout online casino provides games with the most favourable odds and highest return-to-player (RTP) percentages. Conversely, the best payout casinos in the UK are those give you the best payout potential.

Generally, a high-paying online casino has more games with a high RTP, which translates to more money paid out in winnings versus kept by the house.

How do we verify payouts?

At KingCasinoBonus, we extensively test and verify the payout rates advertised by casino sites in the UK to ensure accuracy. Our experts examine official payout reports published by regulators and auditors like eCOGRA to confirm percentages.

However, high payout percentages don’t automatically equal better chances of winning. But the reduced house edge does maximize the value you get from your gameplay. Even a 1-2% difference compounds significantly over hundreds of bets.

Our recommended high-payout casinos excel in two key areas:

• Game Variety – A diverse selection with 97% and even 99% RTP slots and table games with low house edges under 1%.
• Fair Play – A proven track record of statistically sound payouts confirmed by regulators, user input and our experts.

In other words, the best payout casinos selected by KingCasinoBonus provide the best casino payouts possible in today’s market. The key quality relates to the titles that give you high chances and to reliable and prompt payouts.

Lowest House Edge Casino Games

What is the best payout game?

Poker has the smallest house edge, theoretically making it the first among best payout casino games.

However, the game comes with a competitive side and considerable theory to learn. Blackjack is similar, but its fundamental strategy is easier to understand. Plus, it comes with some perks, including blackjack bonuses, given its popularity. Craps comes in third, but it often proves to be intimidating for new players.

Slots are fourth, and this is the case only for the best paying slots with a 99% payout rate.

How to Enhance Your Casino Payouts

You now have your best payout online casino entries to choose from and the best payout casino games needed for your gambling.

This is how you can further enhance your experience:

Learn RTP basics

The return to player rate denotes the amount you can theoretically expect a game to return to you as a fraction of your wagered money.

Mechanic slots used to have complicated contraptions that reproduced the odds given by the RTP rate, with some error. Error that became quickly exploitable, especially in the case of mechanical malfunctions, intended or not.

However, you can rest assured. All online titles, including the top slots from the best payout casinos we picked in our top 20 table use RNGs or random number generators to accurately simulate your chances and expected return.

Understand volatility along RTP

RTP reveals the theoretical payouts, but volatility shows how often you’ll win:

• Higher volatility slots like Book of Dead pay out less frequently yet offer bigger payouts.
• Lower volatility slots like Starburst provide smaller wins more consistently.

Play skill-based games

Slots have minimal input. Certain games like blackjack offer betting strategies that, while not foolproof, can minimise losses. You cannot increase your chances beyond those derived from the RTP rate. In table games, there is an element of luck you can hinge on to increase the payout.

Choose high RTP slots

If you still intend on playing slots, you should at least go for best-paying slots. Additionally, look through the casinos with the highest slots payouts for titles with lower volatilities. This will ensure a prolonged playtime.

Look out for high paying welcome bonuses

Bonus terms dramatically impact your actual payouts, so it’s best to start with a potentially high payout bonus.

The best payout casinos’ welcome bonuses have low wagering and high max payout rates.

Seek low wagering requirements like 20x rather than 60x, which are brutal to clear. Also, watch for uncapped bonus winnings. For example, a bonus where you can only cash out 2x your bonus amount may translate into a limited payout even before you start playing.

Diversify games and casinos to increase your payouts

Sticking to one “lucky” game or site is limiting, often causing big losses chasing past wins. That’s why KingCasinoBonus expert Ionut Catalin Marin advises you to play varied games across multiple reputable, high-RTP casinos.

That’s how you get exposed to more payout opportunities!

Apply bankroll management for long-term payouts

Bankroll management is critical for long-term payout success. You should practice responsible bankroll management because chasing your losses often leads to overspending.

It’s important to know when to stop playing, even if you’re on a winning streak. Our experts recommend setting a strict gambling budget and stopping once you hit your loss limit, regardless of game outcomes.

Does Your Payment Method Choice Influence Your Payouts?

Payment methods have nothing to do with your odds of winning or game payout rates. Your chosen payment method can only influence your payout amount, not the game payout percentage.

Your payout amount has the fees deducted and/or other casino commissions, depending on your chosen payment processor’s policy and the casino terms. Here is a helpful overview that might help you choose your payment method more wisely:
