Criteria for a Best High Payout Casino

Many online casinos offer high payouts, so what makes one of these sites the best? The answer to this question comes down to the following set of criteria.

High Payout Casino Games

The first factor that makes an average high payout casino one of the best is its range of high payout casino games. These games should be from all categories to appeal to customers with all preferences. We like to see slots, tables, live games, and other casino titles on offer. 

Various factors help us determine whether or not a game is high-paying. For example, a high-paying slot will have a high RTP (Return to Player percentage), the average percentage of your total deposits you should receive back in winnings, and high volatility, which means the game pays out in large sums less frequently. 

All the sites on our list offer a selection of high-paying games from all categories, created by the top software providers in the industry.

Top Payment Methods

When playing at the best payout casino, you should be able to access a range of payment methods that can be used for both deposits and withdrawals. Customers should be able to find various payment types; these include e-wallets, prepaid cards, debit cards, mobile payment options, bank transfers, and even cryptocurrencies when possible. All methods should be safe, secure and easy to use. More details on the exact payment methods you should be looking for will be provided later in this article. 

Unbiased Terms and Conditions

All online casinos have terms and conditions attached. These are put in place to ensure that customers are being treated fairly and that the site is protected. Casino terms and conditions relate to payouts on the site, so it is important that they are unbiased and easy to understand. Terms and conditions to look for include monthly/weekly/daily withdrawal limits, wagering requirements, expiry dates, promotional conditions, and more; these will affect the payout. 

Fair Transaction Limits

As we mentioned above, online casinos will often put transaction limits in place; this is for many reasons, one of which is to help players control their gambling habits. However, as great as this can be, it is also important that the site is fair when putting these limits in place; for example, the maximum withdrawal amount should be high with as few restrictions as possible. 

A site with low maximum withdrawals, whether daily, weekly, or otherwise, disappoints customers. We expect the best payout casinos to have low minimum deposits, high maximum deposits, low minimum withdrawals, and high maximum withdrawals. bet365 is a solid example of this. 

Promotions and Bonuses

Another feature that will boost a high payout casino is having a vast selection of casino promotions and bonuses to magnify users’ funds. These bonuses should be available to new and existing customers on the site in various forms. Examples include free spins, bonus funds, welcome offers, free games, free wheel spins, VIP rewards, cashback, and more. These offers should have fair terms and conditions and should be easy to claim. All the casinos on our list have a decent selection of promos.

Other Standout Site Features

The following features are not required for a high payout casino, but help the sites stand out. If you want to join a site which offers all the great features you could want as a player, as well as high payouts, then look for the following:

• Excellent customer support methods (e.g., live chat, email, phone support, social media, post, etc.) are fast, easy to use, and helpful.
• Compatibility with mobile, either through an app or internet browsers, to allow you to play on the go. 
• A UKGC licence and security measures are legal requirements and will help players stay safe while betting at an online casino.
• Good site design makes using the site easy and nice to look at. 
• Responsible gambling tools for if or when your gambling gets out of control.

1. bet365 Games

The first high payout casino on our list is bet365. This top online casino is a household name across the UK for many reasons, including the fact that it offers high payouts. This high payout average is down to the huge host of quality games offered on the site, all of which have decent to high RTP (Return To Player) percentages. In fact, the selection of high RTP games is so good that users can find almost 2,000 titles with an RTP over 95%, which is the majority of games. 

Other great features that make the site stand out include the wide range of payment methods, the various promotions available to new and existing players, the alternative gaming library, and the quality customer support options. The only issue we found with the site is the long verification process.

If you want more information on this great site, check out our dedicated bet365 review.

Pros ✅: 

• One login allows access to all bet365 sites.
• Quick payout times.
• Range of casino games and promotions.

Cons❌:

• Long verification process.

2. Hippodrome Casino

Up next on our list is Hippodrome Casino, which is currently offering new customers an excellent welcome promotion. At this high payout casino, customers can utilise a decent range of payment methods, including debit cards, e-wallets, and prepaid cards, which can be used to withdraw any winnings from the high payout gaming titles offered on the site. 

While playing at this top site, users can find games from all categories, including slots, live casino, jackpots, roulette, blackjack, poker, and more. Games on the site are from top software providers such as Games Global, Evolution Gaming, and Playtech. However, these are not the only reasons why the site stands out; Hippodrome Casino also offers decent promotions, instant withdrawals, and over 450 games. However, we would like to see the live chat support made available for longer hours. 

Pros ✅: 

• Holds licences from MGA and UKGC.
• Various responsible gambling tools.
• Extensive help page.

Cons ❌:

• Live chat is only available from 8 am to midnight.

3. NetBet Casino

Next on our list is NetBet Casino for a host of reasons, but most notably, it has excellent new customer promotions. This is one criterion we look at when deciding whether a top payout casino, such as NetBet, stands out. The site offers not only a generous welcome offer but also a selection of alternative bonuses, which, thanks to the fair terms and conditions, boost the payouts on the site. On top of this, the site has a decent average payout of 95.88%.

However, these are not the only features that make NetBet Casino an attractive online casino to those looking for high payouts or just a fun online gambling experience. Thanks to the great site design and games from all categories, NetBet Casino is great for novice and experienced players. The only improvement the site could make would be the addition of more support options.

Pros ✅: 

• Various social media accounts.
• Offers European Roulette, Ultimate Texas Hold’em, and Single Deck Blackjack.
• Loyalty program available.

Cons ❌:

• Only offers request forms and AI chat for support.

4. talkSPORT BET Casino

talkSPORT BET Casino holds the fourth spot on our list, which will be unsurprising to any players who have a pre-existing account with this top-notch site. For starters, the site adds new gaming titles regularly, which means players should be able to try out all the new games in the industry. In addition to this, the site is great for users who prefer to play on mobile because the site doesn’t just offer high payouts; it also offers its services on mobile browsers and via a dedicated app that can be downloaded on ios and Android.

Those who like to stay updated with site changes and industry changes will likely enjoy the talkSPORT BET Blog. Though, its worth noting that this site is primarily a online sportsbook, and although the casino section is great for high payouts, it is not the brands top priority. 

Pros ✅: 

• An extensive help centre for those in need of support.
• Fair terms and conditions.
• Generous welcome offer.

Cons ❌:

• The site prioritises the sports betting section.

5. Pub Casino

Last but certainly not least is Pub Casino, which has one of the best average payout rates we’ve seen and, as such, has secured its position on this list. This average RTP is due to the vast selection of high RTP games. These games are from 19 of the best gaming software providers in the industry right now. Another reason why the site is so great for payouts is the top tournaments regularly offered. These tournaments offer some great prizes to players who place at the top. 

Players can also find an excellent selection of live casino games alongside the regular titles, and like the rest of the games on the site, these have been created by top software developers. The only issue we had with Pub Casino, which moved it down the list, is that the selection of promotions and bonuses is lacking.

Pros ✅: 

• Unique gaming titles. 
• Range of sports betting markets.
• Easy sign-up process.

Cons ❌:

• Fewer promotions than on other sites.

Best Payment Methods at Top Payout Casinos

As we mentioned previously, having a range of payment methods is vital in creating a top-paying casino. Below, we have listed the types of methods players can find while playing.

• E-Wallets: This is a type of digital wallet which allows customers to store their payment information and make electronic payments online. Examples include PayPal, Apple Pay, and Google Pay. 
• Prepaid Cards: This method allows players to make payments at a site without using their actual banking information. Instead, users transfer money into these cards and then use them to make transactions. Examples include Neteller and Skrill.
• Debit Cards: Most users have heard of and have access to a debit card. It is a card which allows you to make payments from your bank account. Popular examples include Mastercard and Visa. 
• Mobile Payments: A mobile payment method allows users to make payments using their phones, and examples include Apple and Google Pay.
• Bank Transfer: Also known as Wire Transfer, this method allows customers to move money directly from their bank account into their casino account.
• Cryptocurrencies: A type of digital currency which can be used to make payments online; however, it has no intrinsic value, which means the value is simply what players are willing to pay. These are uncommon to find at online casinos, but examples include Bitcoin, Litecoin, and Ethereum.

Best Payout Slots UK

There are so many slots out there so what are the highest paying? We’re here to help. We have listed the highest payout slots.

Ugga Bugga

Released in 2016 by Playtech Studios, the Ugga Bugga slot was and is the highest RTP slot currently available. The game has 3 reels and 10 pay lines, and with a multi-spin feature, users can earn up to 1000x their initial bet.

Book Of 99

The second-highest payout slot currently available is Book of 99. This is thanks to its RTP of 99% and a max win of 5,000x for a player’s initial wager. This Greek Mythology-themed game is played on five reels and allows players to bet from as little as 10p to £100 per spin.

149 Uncharted Seas

In the 149 Uncharted Seas slot, customers can enjoy the expansion of wilds and the exciting free spins feature. This Thunderkick slot allows users to set their spin value between £0.10 and £100, and with a max win of 670x, this could prove to be very lucrative.

Highest Payout Casino Games

If you aren’t particularly interested in slot games, we have listed the current highest-paying casino games available to UK players. 

Single Deck Blackjack

This type of blackjack is exactly what you’d imagine: blackjack, which is played using only one deck of cards. This form of blackjack has the highest payout thanks to its low house edge of around 0.5%. The aim of the game is to have the hand closest to 21. This type of blackjack can be found at most online casinos.

Ultimate Texas Hold’em

Ultimate Texas Hold’em is a variant of poker in which players compete against the dealer with the aim of having the best 5-card hand. This is done by combining their two-hole cards with three of the 5 community cards dealt by the dealer. The house edge for a total bet for this game is 0.53%, and 2.18% for an ante bet. This is one of the lowest of any poker variant.

European Roulette

This roulette variant is played on a roulette wheel with the numbers 0-36. Having only one zero means that this is the form of roulette with the lowest house edge, sitting at 2.70% on all bets. Users can place bets on individual numbers, colours, odds or evens, dozens, or columns while playing. This roulette variation can be found at most UK online casinos.

Responsible Gambling

Responsible gambling is a priority at casino sites, ensuring players’ well-being. The best casinos provide tools like deposit and time limits, as well as self-assessment. For additional support, top casinos offer resources for those who may have gambling issues. Players should treat these casinos as entertainment and take breaks if needed.
