Each piece of content goes through an extremely careful validation process led by our CEO, Ionut Catalin Marin, for editorial integrity and accuracy. Here’s how we verify and edit our content:

Why mobile online casinos are better than land-based casinos
- All the casino features are optimised and work well on mobile, so there’s no downside.
- Since we carry our mobile phones everywhere, casinos can be accessed everywhere.
- Mobile online casinos have a 24/7 schedule, making them more accessible than land-based venues that work on a strict schedule.
- The number of games available in a mobile casino is sometimes 1000 times larger than the number of slot machines and game tables in a land-based casino.
Apps vs browser online casino comparison
| In-browser mobile casinos | Casino apps |
|---|---|
| Faster, direct access from your phone’s browser | Requires you to download an app before accessing |
| Easier process of user experience | Potential glitches on old browser versions |
| Potential security threats of sites with no SSL lock | Secured, vetted by the app store is hosted at |
From what we’ve seen in the 8 years of analysing casinos, mobile browser casino play is still 1.5x more popular than downloading an online casino app. It is easier and faster, and you don’t need to install anything on your phone. Ultimately, the choice is yours.
Tips to optimize your mobile experience

- Have a steady internet connection when making bets, so you don’t lose connection when you play.

Use our filters and customise your search to find the sites that suit you best. First, you select the applicable filtering criteria and instantly see which casinos fit your requirements. Based on your preference, you can select any of the following filters to narrow down your search: game types, bonus types, payment methods, providers, mobile compatibility and many more.

All casinos listed on our website are rated based on a set of predisposed factors that include, among others, variety of games, customer support, bonus value, and user experience. It is important to compare at a glance which casinos come out on top using these ratings.

How to create an online casino account
| Steps | Our Tips |
|---|---|
| Choose Your Casino | Pick a licensed and reputable casino from our recommended list to ensure a safe and enjoyable experience. |
| Register with Accurate Data | Fill in your personal details, including name, address, and contact information. Use accurate and truthful data—never use false information. Misrepresentation could lead to account closure. |
| Set Up a Payment Method | Link your valid payment method to your account. Ensure it’s in your name to avoid issues during withdrawals. |
| Verify Your Email/Phone | Many casinos will send a verification email or SMS. Complete this step to confirm your account and access all the promotions and features. |
| Deposit and Claim Bonus | Make your first deposit using the linked payment method and enter any relevant bonus codes to claim your welcome offer. |
| Play Responsibly | Before you start playing, set deposit limits or time reminders using the casino’s responsible gambling tools to stay in control. |
Why do you need to complete the KYC process?
The KYC process is mandatory for all UK casinos and ensures both your safety and the integrity of the gambling platform. Here’s why it’s important:
- Identity verification: The casino needs to verify whether the information you have provided about yourself is actually true. Hence, you have to send clear photos or scans of your ID, which may be a passport, birth certificate or driver’s license.
- Prevents fraud and money laundering: By identifying who you are and the source of your funds, casinos help keep their gaming environment safe for all gamblers.
- Proving the ownership of payment method: You have to demonstrate that you own the payment method that you’ll be using, such as a debit card or e-wallet. This is necessary so that unauthorized financial activity does not happen on your account.
- Financial background: In some cases, you might also be asked to present proof of income or source of funds. This would ensure that you are betting with funds to which you have a legitimate right.
Safe Online Casino Gaming Tips
| Strategies | Explanation |
|---|---|
| Protect your account with the KYC | KYC protects minors from accessing gambling products that are denied to them by law, protects your details as a gambler and as a non-gambler (since nobody can use your data illegally), and protects the funds you want to spend. |
| Make a budget | When you engage in real-money gambling, you mustn’t overspend. Make a budget before you play to avoid all the potentially negative situations. Set aside some of your money for hobbies, exclude money for necessities and economies and subtract about 15% or 20% from what remains. Bonus tip: use budgeting apps. |
| Play low-house edge games | While playing roulette online for real money is not a better guarantee of success than slots or any other game, it has a predictable house edge, which stands on the low side. This can be said of blackjack online for real money, which should be prioritized by strategic players looking to gain an edge. |

How to use sign-up bonuses in UK online casinos safely
- Start with free spins on sign-up in online casinos since slots are the easiest game.
- You should move up to deposit bonuses only after comparing the best options in the UK.
- If you choose no deposit casino bonuses from verified sources like our experts’ list, you enjoy an extra layer of safety and complete information in an easy-to-digest presentation.
Always read the Bonus Terms
Free bonuses come with strings attached, so it’s best to understand all your requirements before using them. Moreover, regarding 1st deposit offers on sign-up, not reading the bonus rules may have negative financial implications. Sister sites functioning on the same white-label license may restrict your access to their sign-up bonus. To counter that, you can choose from our new independent casino list for 2025. Here’s a quick reminder of the most important bonus terms at online casinos:
- Min deposit: the amount you need to deposit to activate your bonus. It starts at £1, £5 or £10 in the UK;
- Bonus value: the amount of promotional funds you receive from the casino site after your deposit has been processed;
- Eligibility: some bonuses are for new players, while others, particularly reload bonuses, are suitable to claim only by existing players;
- Welcome package: a promotional bundle that contains bonuses for multiple deposits along with free spins, usually spread between 1-5 days;
- Wagering requirement: the number of times you need to play through the bonus value or the deposit and bonus value combined before cashing out real money from it;
- Expiry date: the date after which wagering the bonus is no longer available and you lose any unused bonus funds.

UKGC Licensing and Safety Guidelines
The United Kingdom Gambling Commission regulates all UK online gambling and betting activities. This institution licenses online and land-based operators and checks if the products they offer respect the legislation. They are the ones that create, update, and enforce the legislation. They do that as a result of the joint effort of law experts, psychologists, gambling addiction therapists, and operators alike. Their goal is to set up healthy standards for all sides.
How the UKGC protects you
The UKGC enforces strict standards upon online casinos which act as shields that protect you from scams:
- The UKGC protects your financial situation by not allowing operators to steal your money, lock it in their accounts for no reason, not allowing you to take it back, etc.
- On top of that, they force casinos to be transparent with you. The operator is bound to inform you, in simple terms, of what happens to your funds, where they are stored, in what conditions can they be transferred, etc.
- The casinos are also required to protect your personal data. It needs to be stored securely, not accessible to anyone else, collected minimally only with the details that are needed to verify that the account is yours and you are an adult.
License granting system for online casinos in the UK
- When a UK online casino applies for a license, all these features fall under supervision.
- The site is tested for over 6 months before they get the seal of approval.
- Then, randomly, they go back and test if the terms and promises’ validity is still respected.
- A license can be revoked anytime if the provisions are not respected.
Read the full guide to what the UKGC does to understand better the extent of its regulations and protections for UK gamblers.
UKGC stats
| Gambling market elements | UKGC stats |
|---|---|
| UKGC employees | +100 |
| Number of licensed websites | +2000 |
| Percentage of protected UK residents | 43% |
| Total market GGY | £14.1 billion |
How to verify the casino license and stay safe
Here’s the process we go through when verifying. We suggest you follow the same trail as us:
- Go to the main page of a casino of choice and scroll down to the footer.
- Read the text there (sometimes it might be presented in a smaller font than the rest) and scan until you get to the part with a hyperlink.
- Click on the hyperlink. It should redirect you to the UKGC site, specifically the page where the main operator is listed, and all their licenses are listed (expired, new, or pending).
If you see a green text that says “ACTIVE” under the Status column, the specific license is valid and currently in work. That’s it! If you see something similar to the screenshot above, that means that the UKGC licenses your casino at the moment, and it has passed all the safety standards required. If you can’t see the number in the site’s footer or the main terms and conditions page, if you can’t see a hyperlink anywhere, or if the link sends you to a different page or a page that doesn’t have the green text, stay away from that casino! It is most likely not licensed and can be a scam!
