How we select & review the best new online slots sites?

How we select & review the best new online slots sites

To create this page, we have followed our usual two-stage strategy. Here it is:

Preliminary stage

To publish any review on CasinoAlpha, we sign up for a new player account and complete all the necessary steps to have full access to the site’s features.

These features are submitted to multiple tests for:

  • Data security
  • Loading speed
  • Usability
  • Game catalogue variety
  • Bonus terms
  • Payment options
  • Customer service

After the test results, we give ratings and set the casino between the market average and competing sites. The first stage is, at this point, complete.

Main stage

To add any operator on this page, we compare multiple features to create unbiased tops.

Casino features we compare:

  1. Objective player options like number of games, number of game providers, number of payment options, and the existence of fees.
  2. Subjective player options like graphics, theme, usability, and the attitude of the support agents.

How do we conclude the process?

Once it is proved that a site has both objective and subjective features at an above-average level, we can integrate it into our curated top.

Best new slots sites of 2023

Rank Operator Number of slot games Best feature
#1 Royale500 +2500 Lengthy FAQs that save you time
#2 Wild West Wins +1410 Easy navigation on all devices
#3 SpinYoo +1400 Fast payouts with no fees
#5 Buffalo Spins +1300 Pay by phone & PayPal deposits accepted
#4 Barz +1200 Fast replies from 24/7 support

How we choose our top 5?

We focused mainly on the slot options at hand. We looked for a large number of games, different thematic to each, customizable settings, and, eventually, associated bonuses. That happened in the usual framework that we apply to the best online casinos, namely licensing and all the guarantees, good user experience features, fund protection and responsible gambling methods.

Since we want to be transparent to our UK users, we will take each casino one by one and present them through the lens of their best slot-related features.

Advice when you’re playing these games

Advice when you’re playing these games

  • You can protect your budget when you’re engaged in a free spins no deposit type of promotion.
  • Slot games are fast-paced, so make your sessions shorter and the breaks between them longer.
  • Games are highly optimised on smartphones through the casino app version rather than the browser version.
  • Check if the online casino has not changed the general provider-driven RTP. Sites are allowed to do that, and sometimes they make changes of the sort.
  • When you are in the process of completing bonus wagering, games like these are the ones with the highest contribution.

Staple game providers for brand new slot sites

  1. Microgaming: established in 1994.
  2. NetEnt: established in 1996
  3. Pragmatic Play: established in 2015.

Game providers sought-after on new slot sites must create engaging games continuously, and they have to be as diverse as possible. That goes for everything from graphics to game settings, game volatility, and outcomes.

There are over +200 providers that populate the market. However, the podium that we have presented to you has proven to have a good reputation and a good product catalogue.

Tips

We will update our choice when significant changes happen in the trends and predilections.

Top-charting jackpot slots games

Game title Provider RTP Best feature
Mega Moolah Microgaming 88.12% Adjustable paylines
Mega Fortune NetEnt 96.6% High bet range
Arabian Nights NetEnt 95.22% Higher hit frequency than the usual

Important

Note that, on average, the RTP of progressive or jackpot games is lower by default. That is tied to general game engineering, as the chances of positive outcomes are smaller.

Bonuses for the best new slot sites

Bonuses for the best new slot sites

One fundamental recommendation we have is to link your slot sessions with a casino bonus. We will briefly present each one and how to use them.

Free spins on new slot sites UK – the best pairing

Free rounds are specially designed for online slots. They are basically rounds in the game that don’t decrease your budget.

You can find such promotions in fixed batches of:

Recommendation

To pick the right typology for you, take into consideration your time, particularly when calculating the wagering timeframe.

Minimum deposit slot bonuses – accessible with small payments

New slot minimum deposit casinos are a valid option, mainly because they come from well-known operators, guaranteeing a satisfactory catalogue of games.

Important

We have discovered that small sums dedicated as bonus funds are locked to play on slots exclusively. That means that they comply with the needs of gamblers.

No wagering options on new slot sites

No wagering options on new slot sites

Even if no wagering bonuses have a rarer frequency in the industry, most of them are locked on slot games or come from new UK slot sites.

Tips

Casinos usually send these opportunities at the end of a longer period of time, such as at the end of the week, fortnight, or month.

Cashback bonuses – a viable option

Cashback bonuses are rare to find, just like bonuses with no turnover attached. Even so, when they are delivered, they are associated with popular gaming categories, where online slots reign supreme.

Tips

As gambling experts, we know that these cashback offers are like a plan B when it comes to your fund management. They are calculated by the previous percentages of your losses, which means no additional deposit.

Be aware

Whenever you play with any CasinoAlpha bonus, read our bonus descriptions and then the full T&C text. Otherwise, you risk losing a bonus by unknowingly breaching the rules.

How to choose a site & sign up?

How to choose a site & sign up

  1. rgest part of the research and experimenting for you, so your first step is to choose from our options.
  2. When making a decision, consider the minimum deposit required, allowed games, and the timeframe given to wager.
  3. Always consider your budget and schedule when looking for a new slot site.
  4. Click on the Play button near each bonus title.
  5. Read the text on the landing page that gives you instructions for the next steps.
  6. Follow the step presented, which usually requires you to sign up.
  7. Signing up means sharing your data and contact options.
  8. Most of the time, after signing up, you can make a deposit.
  9. You’re all done and ready to play any slot game in their catalogue.

Recommendation

  1. Sometimes, you need to confirm your phone number or e-mail before being allowed to gamble.
  2. We recommend you save time right from the start and complete the KYC procedure after you log in for the first time. That makes the withdrawal process take less time.

Pro-tips for optimised play on 2023 new slot sites

Pro-tips for optimised play on 2022 new slot sites

  • Look and assess if the game selection and the list of providers are to your liking. Unless you find titles you like or want to try, it is not worth your investment.
  • Make sure to read our review and the site’s T&Cs to find out if there are any fees applied to your withdrawals. Most slot outcomes are not hefty, and fees may change them significantly.
  • Confirm if the customer support options work and give out genuinely helpful answers. Not having someone to answer or help may be problematic.
  • Choose casinos with a good reputation. That is easily discoverable by looking at the licencing and our reviews. We always take into account player opinions.
  • Whenever you can, look for rarer options for slot-related games, like free spins for adding card. Such offers break the monotony of the usual incentives.

Transactions management

Transactions management

Your budget is vital to your gambling experience. Thus, we want to share easy tips to deposit and withdraw correctly on brand new slot sites.

Making a deposit the right way

Your first step is to check if you can use popular UK methods. Amongst them, we recommend:

  • PayPal
  • Skrill Moneybookers
  • Neteller
  • Pay by phone

Note

Classic bank cards are still very popular in the UK, and we can confirm that you can use them on the sites we list here too.

Of course, you need to check if fees are applied and if the money landed in your account after you’ve made a deposit. Usually, that happens within a few minutes.

Important

Don’t use a payment service you are not familiar with. That may cause issues that are easily avoidable.

Making a withdrawal easily

Withdrawing should be requested when you have no pending wagers or previous transactions.

Then, you need to use a withdrawal method you’re comfortable with, with no fees attached.

You may see fees for:

  • Transactions smaller than £10;
  • Transactions over £100;
  • Multiple requests on the same day;
  • E-wallets

Pros and Cons

Pros
  • Satisfactory diversity when it comes to the slot catalogue, both in number and thematic
  • Partnerships with top game providers
  • Multiple bonuses available
  • Easily used via your phone’s browser or casino app
  • Early access to newly released games
  • Good user experience
Cons
  • Less jackpot or progressive titles available
  • Hard to judge the reputation by yourself
  • Limits when it comes to other gaming categories

Page methodology and resources

Page Methodology

We have a set of pre-set markers after which we judge the standards of viable casinos to recommend. These are fixed and guarantee safe experiences.

When it comes to the initial collection of options, we resorted to:

  1. Our own database of UK operators
  2. United Kingdom Gambling Commission listings and news
  3. eCOGRA certifications
  4. iTechLab certifications

Why these sources?

They operate to the highest standards of fairness and player protection, whether it relates to user privacy or protection against harmful gambling. Your safety is our priority.

For the applied tips and tricks, we used:

  1. The Gambling Act of 2005
  2. Academic journals which highlight the importance of healthy gambling
  3. The latest directives in terms of data privacy
  4. Our own experience as gamblers, knowing your needs firsthand.

F.A.Q

Are new slot sites safe?

Yes, as long as they are licenced actively by the UKGC, they are safe. All CasinoAlpha UK new online slots sites have the UKGC seal.

Are all online slots linked?

No. Certain online slots are linked in the sense that all the best made across all casinos that operate them raise the general total jackpot. That only happens with some progressive slots, like Mega Moolah.

Is there a winning strategy for slots?

Slots strategies have less to do with the game and more with money management. As long as you don’t bet your profits and don’t exceed your budget, you’ll be fine.
