At Gamblizard, our casino reviews stem from a system that evaluates seven criteria and 32 subcriteria, each weighing differently in the overall score (see the diagram). Depending on the final score, we say the analysed casino is Excellent (4–5), Standard (2–3), or Acceptable (1).
Our rating system reflects the overall quality of the reviewed casino. Still, regardless of the score, you’ll see only the recommended brands on our website. The difference lies in the additional value a brand may offer you as a potential player.
Our scoring methodology precludes hidden rankings or biased placements and secures data-driven assessments based on transparent equations. You may consult the general formula or examine how the scores are calculated criterion by criterion.
Our approach to compiling this list is qualitative, not quantitative.
First off, we set key standards related to the company profile and launch recency that brand new online casinos must meet to be included. Then, we go over our database of rated brands to see which do. At that point, we sort and rank them, considering the most relevant aspects of these casinos’ portfolios and UX.
Brands that pass all checks make it to our list. They are granted twenty respective positions.
Selection Standards:
Disclaimer: This compilation does not prioritise competitive payouts as its primary ranking criterion. If you’re searching for new casinos offering high withdrawal limits, visit our Best Payout Online Casinos page.
⚠️Factual data are subject to change without notice from the casino. While we do our best to update our content promptly, inaccuracies may occur. If you discover a misstatement in our materials, please contact us.
The Gamblizard team takes a meticulous approach when looking for the best new casino sites. This is why we use a strict list of important criteria when reviewing casinos, such as:
It’s no secret how important licensing is for the best UK casino sites. The first thing our team looks for is confirmation of a casino’s licence, as there are some websites out there that operate without one. Making sure the latest casinos have strict security measures and valid permits is top of our list, reassuring you that all casinos recommended by us are 100% trustworthy.
A new online casino isn’t necessarily a site that’s only just been launched. Any casino up to 3 years old is classed as “new” by our experts. It’s also common for large corporations to acquire and re-brand UK casino sites. The Gamblizard team always does a thorough investigation into the origins of all new casinos online to establish their true age and history.
We evaluate every aspect of the bonuses we come across, including all terms and conditions. Our team looks for an optimal balance between generosity and fairness.
Did you know that 80% of online casino members use mobile devices to access games? Today’s newest online casinos must optimise their mobile presence to keep up with demand, which is why we thoroughly test casinos using smartphones and tablets, as well as traditional desktops. This gives us a feel for how compatible a casino truly is with mobile play.
From e-wallets like Skrill to classic payment cards like Visa, we’re always on the lookout for a variety of payment choices at the newest online casino sites. Convenience and security are crucial, no matter if you’re at a new PayPal casino or a site that prioritises debit card payments.
From response speed to contact method variety (such as live chat, email, or phone), we evaluate all aspects of new online gambling sites’ customer support.
Our team examines all game categories, including slots, table games, progressive jackpots, and new online casino games, evaluating their quality and diversity. Brand-new titles crop up daily across many sites, meaning we always stay up to date throughout our investigation process.
A new online casino is a recently opened gambling site where you can play slots, blackjack, roulette, poker, and other casino games. You can access these casinos through your web browser on both desktop computers and mobile devices. Some casinos have even launched dedicated apps for the latter.
On the surface, new UK casino sites are just like those you are accustomed to. However, these newcomers often have the upper hand in terms of deposit bonus offers and other perks.
Check out the key steps to follow to play at new casino websites and claim the best UK casino bonuses.
Choose a new casino site from our list Before you progress to creating an account, you must choose a casino that suits your gaming needs. To make your decision easier, the list below contains our top picks that offer the utmost security and quality.
Register for an account Once you’ve selected your new casino online, it’s time to join officially. Find the “Create Account” button (or similar) on the homepage, and you’re ready to get started. You’ll have to provide some personal details, including your full name, email address, date of birth, and phone number.
Provide ID to verify your account To maximise safety and security, all of the best new casino sites require you to verify your identity. You’ll need to upload copies of official identification documents (such as a driving licence or passport) before you can deposit money and play.
Make your first deposit Find the banking section of your account, and you’ll see all available payment methods. Carefully choose the option you’d like to use, and insert the full deposit amount.
Claim your bonus As a new member, there’s a high chance you’ll have a bonus or promotion available to claim. So, once your first deposit is confirmed and meets the specified requirements, you’ll be able to claim the casino’s welcome bonus. Common bonuses include free spins or percentage match bonuses.
Start playing Once you’ve completed all of the aforementioned steps and your account in the new online casino is ready and raring to go, you’re free to pick your preferred game and begin playing.
Understandably, some players might feel sceptical when it comes to trying out new online casino sites. However, the advantages these casinos bring to the table are more than enough to appease even the biggest doubters, so let’s check them out:
It’s not easy for any brand-new UK casino to join the crowded iGaming market, as the industry is ruled by casinos that have been operating for over a decade. So, how can a new trusted online casino challenge the older ones? The secret lies in a couple of key features.
The bonuses you’ll find on the latest online casinos are usually far more generous than those on old sites. New no deposit casino promotions that provide extra starting funds usually come in the form of bonus cash or free spins. Players receive these without having to give anything in return.
New online casinos Ireland- and UK-based are more in tune with the latest industry trends. They have dedicated mobile apps, VR-powered, games and other novelties that older casinos aren’t so keen to implement.
Older and more established casinos still have solid advantages. Typically, the longer they are in business, the more players are inclined to trust them. Good casino reputations build over plenty of years with thousands of satisfied customers, giving new players lots of reasons to join.
The only way for the newest casino sites to make a name for themselves is to offer an extensive portfolio of games from the best software providers. Game developers are without doubt the key to a casino’s overall success. Without the best quality games from renowned providers, a new online casino will struggle to keep up. Luckily, many of the newest UK sites know this and feature plenty of big names. These include NetEnt, Microgaming, Evolution, Pragmatic Play, Playtech, and others, but it’s not just about quantity; the quality of a casino’s games matters just as much.
Hands-down the most popular type of casino game, slots cover a multitude of themes and formats. Many new players look for free spins at new casino sites, simply because of their love for slots. From classic 3-reelers to more modern multiple-reel and payline, including the famous Megaways with 117,649 ways to win, slots are a must-have for any new online casino.
More classic players are likely to gravitate towards table games over slots. Luckily, all of the best new online casinos offer many choices, including blackjack, roulette, craps, poker, and more. Live dealer sections are sometimes even more popular than regular table games, due to their ability to replicate a real-life casino game. You can play against other real players with a live dealer that’s streamed in real time.
The best new online bingo sites will offer many varieties of bingo to its players, including 30-ball, 75-ball, 80-ball and 90-ball bingo. Many sites offer ticket bundles, making bingo a very popular option as you can play the same game with multiple tickets to increase your chances.
Some new casino sites offer crash gambling options, such as the Aviator game. Players place bets on multiplier values, as a curve continues to rise as the game plays out. The trick is deciding when to cash out before the curve ultimately crashes.
Our experts have found that promotions available on some new casino sites are typically more generous than those at older casinos, with examples including:
Players who have registered their accounts for the first time can claim new no deposit bonuses. These give bonus funds or free spins without requiring any money to be paid. You could also receive a “match bonus”, which matches a percentage of your initial deposit up to a certain amount.
The best new casino sites will reward regular players as well as new members. Reload bonuses are a common way for casinos to reward loyalty, with all players able to claim them. These promotions are typically only available on specific days, so be sure to check regularly to avoid missing out.
This type of bonus involves a portion of a player’s accrued losses being given back as bonus credits to play with. Typically, this sum doesn’t exceed 10% of the losses up to a certain amount. Given that losses are an integral part of online casino gaming, cashback offers help soften the blow.
New casino sites often feature exclusive VIP programmes for loyal players to join. The more you play, the more points you’ll earn. You can then exchange these points for rewards such as free spins or bonus cash.
Any reputable new casino website will feature some of the best payment processors for its players to use. Varied options give players greater flexibility, with many sites offering a choice of fast deposit and withdrawal options. We’ve even found that a number of new online casinos are removing withdrawal fees.
To better understand the payment options available to you, check out our list below.
E-wallets such as PayPal, Skrill, and Muchbetter often have the upper hand over more traditional payment methods. They typically process withdrawals fastest, provided all KYC procedures have been completed.
Methods such as Visa, Mastercard, and Trustly are key members of a new casino site banking section. They are regarded as the most traditional online casino payment methods as they directly link to a player’s bank account. In fact, Trustly goes one step further with its Pay N Play feature. At a new Pay N Play casino, you don’t even have to create an account to make a deposit, as Trustly will already have your identity information confirmed.
More and more players in Great Britain are picking prepaid options like Neosurf. Using a convenient voucher-like system, you can purchase Neosurf vouchers and use them to make casino payments.
