How Do We Rate New Online Casinos

Every casino we test must meet our high standards. Here’s a look at what we consider when we rate the new UK casinos we review.

Pros & Cons Of Choosing A New Online Casino Site

Here’s a look at the primary advantages and disadvantages associated with new UK online casinos.

Pros

Cons

Clunky desktop experience – Since many new brands focus on their mobile offering, desktop/laptop interfaces are not always as seamless as they could be.

New Casino Bonuses

One thing brand new casino sites tend to have in common is offering thrilling welcome offers and other promotions. Popular types of bonuses include*:

Welcome Bonuses

This is an offer exclusive for new players. It is available after registering an account and is usually claimable with a first deposit. Players are awarded up to a certain amount of bonus money from the casino (e.g. 100% Bonus up to £100) that can be used to make real money wagers for the chance to win real money on select games.

Free Spins

Free spins promotions can be available to both new and existing players. Players receive a certain number of spins with a predetermined value to play on one or more select slots games (e.g. 10 Free Spins – spin value £0.10 per spin – on Book of Dead). Free spins can be given in the form of a no deposit offer, as a welcome offer or part of a welcome package, as tournament prizes, etc.

High Roller Bonuses

These are large bonuses that are reserved for players who deposit frequently, are premium VIP or loyalty members and who generally play higher stakes table and card games. For their loyalty they may be offered a high roller bonus (e.g. 50% bonus up to £1,000) which can be used on table/card and live casino games, not just slots.

Cashback Bonuses

Cashback bonuses refund a percentage of a player’s net losses over a set period of time and may be linked to specific games (e.g. get 10% cashback on slots every week). This type of bonus is typically available as an ongoing promotion or loyalty reward.

No Deposit Bonus

This is a type of bonus that new UK-licensed online casinos typically offer to new players. It is usually awarded after registration. No deposit bonuses are often small (e.g. £10 No Deposit Bonus or 10 No Deposit Free Spin). The main reason why they’re so popular with new casinos is it gives players the chance to try real money games without having to first deposit and use any of their money.

Note: All casino bonuses and promotions are subject to T&Cs.

New Casino Payment Methods

Most brand new online casinos offer the top popular UK payment methods, including debit cards, eWallets, prepaid cards, bank transfer and mobile payments.

**Note: Deposit and withdrawal processing times vary from casino to casino and some payment methods listed may not always be available for withdrawals.

Established Online Casinos Vs Brand New Casinos

Not sure which experience might be better suited to you? The following are the main differences between well-established online casinos and those that have been newly launched.

Bonuses

Games

User Experience

Credibility

✅Established casinos – The longer a casino has been around, the longer it has had to prove its reputation and gain credibility. This makes established brand more immediately trustworthy.

✅New casinos – New sites have not yet had the time to build their brand identity. They rely on casino reviews and player feedback/reviews to help encourage new players to give them a chance.

New Online Casino Payout Rates

Before playing at any new online casinos, be sure to check their payout rates. A payout rate is a statistic that gives you an idea as a player of your probability of winning at the game you’re playing and your probability of losing the game in the long run if you attempt to chase a big win.

Payout rates are more commonly known as Return to Player (RTP) percentage. Every online casino game has an RTP percentage, which indicates the average amount of money the casino will payout to a player after the player makes a bet (e.g. a game with a 96% RTP indicates the casino pays out £96 for each £100 you wager on average). RTP typically ranges between 80% up to 97% or higher depending on the game.

That being said, RTP is not determined by the frequency of wins resulting on a given game. RTP is indicative over time. There is always an average RTP in the long term, regardless of the bets you make and the gains you receive. However, games with higher payout rates offer players higher chances of big wins. Still, as is the case with all forms of gambling, high RTP or not, no win – big or small – is ever guaranteed.

How to choose a new casino with fair and hight payout rates

The best brand new online casinos will not conceal information regarding their payout rates. In addition to ensuring the casino has transparent T&Cs, low wagering requirements, and fast withdrawal processing times with no or limited casino pending times, we recommend looking for the following:

Signs Of Suspicious New Casino Sites

Unfortunately, not all new casino sites are legitimate or are interested in providing players with a fair, safe, and responsible online gambling experience. As such, it is important that you protect yourself from disreputable operators. Avoid playing at casinos that have any of the following red flags.

Remote (online) gambling is legal in Great Britain for UK residents who are 18 years of age or older. For nearly two decades, UK residents have been permitted to play at online casinos that are legitimately licensed by the Gambling Commission, the United Kingdom’s official regulatory authority, which functions under the Gambling Act 2005. All iGaming destinations, whether they are established or brand new online casinos, must have an up-to-date UKGC license to legally operate and advertise to players in Britain.

Holding one of these licenses means that established or new online casinos must adhere to the stringent rules and protocols that have been put into place by the Gambling Commission. These rules are designed to ensure that players are provided with a secure, fair, responsible and transparent gambling environment. Among the protocols include:

Any UKGC licensee that fails to adhere to regulations can face fines, legal action or closure.

Laws and regulations are frequently changed and updated by the UKGC to ensure that UK residents are continuously provided with the highest protection against financial and other gambling-related harm. Recently, the regulator banned gambling with credit cards and credit card-funded eWallets. This ban went into effect April 2020 to help reduce problem gambling in the country by preventing UK residents from gambling with money they may not have.
