This casino is one of the newer sites but it offers more than many competitors that have been around for longer. If you're looking for somewhere that offers well over 1500 games, a FreePlay option on STS slots, and a generous welcome bonus, consider this UK operator.

What’s good about this is that the wagering is set at 35x, which is very reasonable when compared to the competition. Many other top sites have offers at the 40x mark.

All you need to do is sign up for a new account at You’ll need to deposit at least £20 initially and use the matched bonus on slots.

Please note that you must enter promo code CWFS50 to claim the offer, so don’t forget to add that at the deposit stage.

This is a solid promotion, and you have seven days to wager any free spins winnings 35 times, which is a reasonable timeframe. In comparison, there are some operators that have 24 hour or three-day expiries on slot bonuses.

How to Claim the New Customer Bonus

Knowing how to get a bonus is not always straightforward. Here’s our helpful step-by-step guide to help you with the STS Casino sign up offer.

How to Get the 50 Free Spins

STS Casino Bonus Terms

The STS Casino bonus is available on the following slots only: Starburst, Finn and the Swirly Spin, Twin Spin, and all Pragmatic Play titles.

Bonuses for Existing Players

One of the signs of a leading UK casino is regular bonuses for loyal players. At STS Casino, the variety continues after signing up. Promotions are continually introduced and, currently, there is a Weekend Wheels ‘N Reels offer.

Simply bet during the weekend on the best slots and you could receive some appealing bonuses.

When putting together our STS Casino review, we found that player bonuses change regularly, so make sure you check each month to see if there’s a promotion you like the look of.

Over 1500 Games to Pick From

With over 1400 slots and 100+ table games available, STS UK players are spoilt for choice. Whether your preference is roulette, blackjack, game shows or progressive jackpot slots, this site offers you a well-rounded online casino experience.

The amount of games listed at STS is up there with the very best in the industry. You’ll come across leading titles from top gaming suppliers such as NetEnt and Play’n GO.

STS also go above and beyond to make it easy for players to locate their favourite games. While many UK sites simply list the games on offer in a few different sections, this casino divides them up into numerous categories, including:

A nice touch that sets STS Casino apart from the competition is that they list exactly how many games are on offer in each section. So, for example, you can see that they have over 500 Microgaming slots.

If you want to play any slot without using real money, simply hover over the game and select ‘Practice Game’. STS will give you 1000 free credits so that you can test it out. It’s something casinos rarely offer, so it’s great to see demo mode available here.

Minimum and Maximum Bets Per Casino Game

As part of our STS Casino review, it’s important to let you know the limits for the most popular games. Here’s a helpful table that outlines the minimum and maximum stakes for slots, roulette, blackjack baccarat, and poker.

Choice of Software

It’s instantly clear to players which software providers are available at STS Casino. This is due to the useful list of games per supplier the site has.

The software available includes:

There are currently 15 software providers supplying games at STS. This is an average number when compared to other top UK sites. Some offer 20 or more, but 15 is plenty, especially when all the top titles are included.

STS Live Casino

Evolution Gaming is a leading provider of live games, and they supply the most at STS for UK players. Pragmatic Play are also listed, but they’ve only got three titles in the lobby:

  • Live Roulette A
  • Live Speed Roulette
  • Mega Wheel

In contrast, Evolution Gaming has 37 games listed on the live casino home screen, which is helpfully broken down from highest to lowest:

  1. Blackjack – 10 tables
  2. Game shows – 10 games
  3. Roulette – 9 tables
  4. Poker – 7 tables
  5. Baccarat, Craps & Sic Bo – 6 tables

However, these numbers don’t reflect the total amount on offer. One of the options is listed as a roulette lobby. By clicking on this, it takes you through to an additional area that lists even more games.

For example, you will find a roulette table available in Romanian in the additional lobby. You won’t see this on the initial list of games.

Most games are available to play 24 hours a day and the live dealers make for an authentic and immersive online casino experience.

Players can also get the feel of a real casino courtesy of Casino Malta. One roulette table offers a live stream from this venue. The wheel is spun on a live stream from the casino as you place bets online.

With stakes as low as £0.10 and as high as £10,000, there are tables to suit all bankrolls. This live casino caters to all players and is very easy to navigate. It’s on par with many other live casino games libraries in terms of what’s available.

UK and Malta Licence

STS holds a valid licence in the UK and Malta. Holding one valid licence isn’t straightforward, so having two reaffirms just how trustworthy they are as a company.

These are two of the toughest regulatory bodies in Europe. Because they operate separately from each other, it shows just how safe and secure betting online at this casino is.

Plenty of Payment Options

There is a wide range of payment methods available with STS. The most common choices are covered. The minimum deposit for each option is £10, which should be suitable for most bankrolls.

Although you won’t find a native STS app on Android or iOS devices, the mobile site works very well. After reaching out on live chat, the agent said that they are ‘planning to release it in the future’, so watch this space.

The layout using a mobile browser is great and really easy on the eye. There’s a helpful quick navigation menu at the bottom, which more options in the top-right hand corner.

One drawback with betting at STS on smartphones and tablets is that you don’t get the chance to play games for free. You can test out different titles on desktop, but this option is not available on mobile.

Starting out in the Polish market, it’s no surprise that you can switch between the English and Polish language. Many UK mobile casinos tend to just stick to English, so it’s good to see STS offering another option.

When players look for a new casino to sign up with, round the clock customer support is often a prerequisite. STS offers 24/7 support via email and live chat.

It’s worth noting that live chat is not always available. If agents are busy, rather than waiting in a queue, you are invited to send your question via a contact form. Expect to be waiting up to 48 hours for a reply this way.

For any email queries, feel free to use [email protected]. It’s a 24/7 operation, and the response times vary from a couple of hours to a whole day during busy periods. We found that a daytime email got a quicker response compared to an evening email.

If you need answers to a common query, please make use of their extensive FAQs first. You’ll probably find what you need there. It’s really well laid out and the Q&As are divided into sections to make it easier.

Tips & Tricks

In the footer of the UK site, there’s a link to an RTP (Return to Player) page. If you click through, a full list of the STS games will be listed with their RTP percentage.

This extremely useful for anyone wanting to play the games with the highest payout rate. It’s rare to see casinos list every single RTP percentage, but it’s great for you and me as players.

STS UK players can also access additional live games. Simply choose ‘Roulette Lobby’ in the live list to be taken through to another section that shows many extra tables.

Demo mode is a great desktop feature for anyone who wants to try out new and popular slots before using real money.

Where Does the Casino Need to Improve?

During our STS Casino review, we didn’t uncover too many negatives. But nothing is perfect, so there are a couple of things we’d like to see improved.

It would be great to have the STS slots demo mode available on mobile. You can test out all of the games on desktop, but, unfortunately, it’s not an option on your smartphone or tablet. As mobile betting is become the primary focus, adding FreePlay on all games would be highly beneficial.

We’d love to see live chat accessible 24 hours a day. Although it’s advertised as being available round the clock, it’s often unavailable in the evenings. This can result in players waiting hours for a reply to their queries.


With 1500+ games available and a well-designed site on desktop and mobile, consider this UK casino as a new site to sign up with. They even offer practice mode on every slot, which many top UK competitors don’t have.

Overall, our STS Casino review has shown that this operator it is a great choice for any new casino player. Start your journey by claiming their welcome offer of 50 free spins.
