Casino Games

Playing at an online casino gives you access to thousands of exciting games. This gives you a unique opportunity to explore different games, find your favourites, test your luck and maybe take home a big win. It's about making the right choices and enjoying the entertainment.

Fair Games

When you play, it's important to know that casinos offer fair games. All licensed online casinos use technologies that ensure random outcomes. Live games are often based on genuine randomness, while automated games use a random number generator (RNG) to ensure fairness.

Licensed casinos cannot influence the outcome of the games, and any breach of this would quickly result in the licence being revoked. This is your assurance as a player and gives you a safe experience at online casinos.

Slot Machines at Online Casinos

Slot machines are without a doubt the most popular games at online casinos, offering an enormous selection. At the best casinos you can find over 5,000 different slots!

Remember the nostalgia: Try the classic Jackpot 6000 and relive the feeling of the old land-based slot machines.
Like big wins? Try out Mega Moolah, known for its record-breaking jackpot payouts.

Slots have it all: choose between action-packed games like Gonzo's Quest or simpler, entertaining options like Starburst. The possibilities are endless, and you're guaranteed to find something to suit your taste.

What Is a Slot Machine?

A slot machine is a game of chance made up of reels filled with symbols. When you spin the reels, the goal is to land a winning combination based on a paytable. This table shows which combinations result in a win, and the payouts vary depending on your stake.

Why Choose Online Slots?

• Higher winning chances: Slot machines often have better odds than many other casino games.
• Fast entertainment: A single game is over in seconds, and you'll quickly find out if you've won.
• Big wins: Many players have won millions with small stakes.
• Action-packed experience: Slot machines are packed with features like bonus rounds, free spins and high intensity.

Different Types of Slot Machines

Slot machines come in many varieties to give you exactly the experience you're looking for:

• 3-Reel Slots
• 5-Reel Slots
• Fruit Machines
• Jackpot Slots
• Megaways Slots
• Bonus Buy Slots

Free Slot Machines

At ComprCasino you can try slot machines for free before playing with real money. Our reviews include free-play versions, so you can get to know the game.

Online Casino Legality

Playing at an online casino is legal in the UK, provided the operator holds a valid licence from the UK Gambling Commission (UKGC). Many UKGC-licensed casinos also hold additional licences, such as an MGA (Malta Gaming Authority) licence, allowing them to operate across other jurisdictions too. The most important thing is to make sure the casino holds a valid UKGC licence before you play.

Licences and Security

What do the UK Gambling Commission (UKGC), the Malta Gaming Authority (MGA) and Antillephone (Curaçao) have in common? They are all recognised authorities that regulate online casinos. At ComprCasino, we only work with UK online casinos that hold a valid UKGC licence.

Why are licences important?
A licence ensures the casino follows strict rules for fairness and accountability, including:

• That winnings are paid out correctly.
• That games are fair and based on random outcomes.
• That vulnerable players receive protection and the support they need.

These regulations give you as a player a safe experience and ensure that casinos maintain a high standard.

How to Choose an Online Casino?

With so many options, it can be challenging to find the right online casino, but we've made it easy for you. As long as the casino is approved by our experienced experts, you can feel confident in your choice.

What do we do for you?

• We verify that the casino holds a valid licence.
• We evaluate the welcome bonus and promotional offers.

While every casino has its pros and cons, many of these details are subjective and depend on personal preference. Choose an online casino from our top list that feels right to you - it's quick and easy to sign up. And if your chosen casino doesn't live up to expectations, you can always try another one from our list!

Wagering Requirements

When we assess new online casinos, we look at more than just the bonus size. We also take into account terms, wagering requirements and bonus percentage to give a comprehensive assessment. For example, we wouldn't rank a 25% bonus up to £3,500 with a 50x wagering requirement higher than a 500% bonus up to £50 with a 10x wagering requirement.

We always read the fine print to make sure you avoid unpleasant surprises. If a casino has strict wagering requirements, short deadlines or winnings caps, we make sure to highlight this clearly in our reviews.

Blackjack

Blackjack is one of the most popular casino games - not just because it has a high probability of winning, but also because it's easy to learn.

Online, you'll find far more variants than at land-based casinos. Here are some popular versions of Blackjack:

• Single Deck Blackjack
• Pontoon Blackjack
• Blackjack Surrender
• Blackjack Charlie 7

Roulette

Roulette is the very symbol of glamour and excitement in the world of casinos. It's also a favourite among high rollers due to the high stakes involved.

Roulette comes in several variants, each with its own rules and payout percentages. Here are some of the most popular types:

• European Roulette
• American Roulette
• French Roulette
• Lightning Roulette

Baccarat

Baccarat is an iconic game often associated with James Bond. The rules are simple, and the game gives you the chance to bet on the house winning - allowing players to take advantage of the House Edge.

This makes Baccarat an exciting choice for players looking for a unique blend of strategy and luck.

Game Shows

Game shows are a modern game category that has become a huge success at live casinos. These games are often inspired by TV shows like Deal or No Deal and include popular options like Crazy Time and Monopoly Live.

A live host or hostess runs the game, and you play against other participants, creating a social and fast-paced experience.

Popular Live Casino Games

Live casino has exploded in popularity in recent years, and the online experience keeps getting closer to what you'd get at a physical casino. Here are some of the most popular live games:

• Live Blackjack: Many variants with different stake levels and RTP. Popular versions include Blackjack Party and Power Blackjack.
• Live Roulette: Games start quickly, with new rounds every 60 seconds. Some tables also offer dealers who speak your language.
• Live Baccarat: Growing rapidly in popularity, especially with new variants like Lightning Live Baccarat that add extra excitement.

How to Make a Deposit?

Many players face challenges making deposits at online casinos due to local banking restrictions in certain jurisdictions. At ComprCasino, we give you a thorough guide to the payment solutions available and how to navigate around these restrictions.

Most operators still offer smooth deposits and withdrawals. It may be necessary to register an e-wallet or use an internationally registered bank card, but this gives you quick access to a huge selection of exciting games.

Card Payments at Casinos

Since April 2020, UK banks and card providers block credit card payments to gambling sites under Gambling Commission rules, but debit cards work as normal at UKGC-licensed casinos. Where a card doesn't work directly, you can, for example, use it to top up an e-wallet, which can then be used for deposits. Many e-wallets also offer their own internationally registered debit cards, which work perfectly for both deposits and withdrawals.

Cryptocurrency at Casinos

The use of cryptocurrencies like Bitcoin, Ethereum and Litecoin has grown rapidly, especially at Curaçao-licensed casinos. Cryptocurrency offers fast transactions and full anonymity, but requires that you already own crypto.

E-Wallets and Prepaid Cards

E-wallets like MuchBetter and AstroPay are among the easiest and fastest methods for depositing money at casinos. These solutions offer low fees and fast transactions, for both deposits and withdrawals.

Mobile Payment

While some local mobile payment apps aren't available at casinos, there are alternative mobile apps you can use instead. A few of these come with fees or limited availability depending on your region, but the mobile-friendliness of most payment methods makes it easy to play directly from your phone.

Best Payment Methods

Here are some of the most popular payment methods:

Payment Method Type Deposit Time Withdrawal Time Visa/Mastercard Card/debit card Instant 1-5 days MuchBetter Payment app Instant 1-3 days NeoSurf Prepaid card Instant 1-3 days AstroPay Payment app Instant 1-5 days Bitcoin Cryptocurrency Instant Instant

How to Make a Withdrawal?

To withdraw your winnings, you must use the same method you used for your deposit, and the wagering requirements must be met. We provide details in our reviews about processing times and terms for each casino.

The best casinos usually send the money within a day or two, without fees, and withdrawals can be made in pounds sterling.

Withdrawal Limits and Timeframes

All casinos have minimum withdrawal amounts, and larger winnings may require partial withdrawals. Processing time depends on the payment method, with cryptocurrency being the fastest option.

The KYC Process

As part of the security protocols, all players are required to complete a KYC process (Know Your Customer). This may involve verifying your identity, address and payment methods to prevent fraud and money laundering.
