Though first established in 1997, STS didn’t launch its online services to the European market until 2019. Since then, it quickly became a popular online sportsbook and casino destination for UK players. STS casino is fully licensed and regulated by the UKGC and provides many secure and popular GBP payments, including PayPal, Trustly and MuchBetter. It is well known for its wide games selection of nearly1,500 titles from top slots and table game providers. Discover everything this brand has to offer UK players in our STS casino review.

STS Sign Up Offer

UK players new to STS can claim a 100% matched casino welcome bonus up to £100 with their first deposit. Claiming the STS welcome bonus is easy.

  1. Register an account
  2. Use the bonus code: CWBUK100
  3. Make your first deposit (minimum £10 to qualify)
  4. Your deposit will be matched and the bonus funds will be added to you account

Terms and conditions apply to all STS casino offers, including the welcome bonus. The Key terms for the new customer Matched Bonus of up to £100 offer are:

*Games that count toward wagering requirements for this offer include:

The STS sign up offer is a relatively standard welcome bonus. There isn’t much about it that stands out – good or bad – compared to other new customer offers from previous UK casinos we’ve reviewed. On the downside, only select slots count toward wagering requirements, so this bonus doesn’t offer much to players who’d rather play table games. On the plus side, it’s a nice-sized match-bonus with flexible and fair bonus wagering requirements.

Ongoing Casino Bonuses

There are always STS promotions on offer for existing players.  That said, many are time-limited. There are a few ongoing promotions throughout the week, but all in all you won’t find an abundant of ongoing promos happening there on a weekly basis.

With that said, some of the ongoing STS offers currently available include:

Loyalty & VIP Program

There is no loyalty or STS VIP program for casino or sportsbook players. Hopefully this will be a feature that STS casino will add in the future. For now, the best way to get the most out of your real money play is to take part in the available ongoing promotions.

Range of Casino Games

The number of STS casino games is just shy of 1,500 and there are new titles being added all the time. The game categories include Video Slots, Megaways, Jackpots and Table Games. There are 7 main software providers contributing to STS’ growing games library, with NetEnt, Microgaming, Pragmatic Play and Thunderkick among them. Easily the most popular games in the casino are the Megaways slots, which feature multiple win lines that can expand in number up to hundreds of thousands of ways to win. You can discover the RTP of each game in its info.

Live Casino

The STS live casino includes live roulette, blackjack, baccarat, poker and game shows broadcasted in HD and in real time from Evolution Gaming and Pragmatic Play studios. Once you’ve joined a table or a game show, you can interact with the human dealer or host via live chat while you place bets and play in real time.

The STS section of live casino games also includes Microgaming’s “Real” series, which are RNG-based games, featuring pre-recorded video of live dealers to provide more interactive play.

With over 80 titles, STS offers a great experience for those who enjoy more real-world casino authenticity with their online play.

Examples of STS live dealer games UK players can enjoy on desktop or mobile include:

STS Mobile Casino & App

While there is a fully optimised, high-quality STS mobile experience that you can enjoy via your device’s web browser, there is no STS mobile app.

You do not need to download STS to use the mobile web version. Simply launch your preferred web browser on your phone or tablet, and you can register and/or login to your existing account anytime and anywhere there’s an internet connection.

As is the case with most UK online casinos, the STS casino mobile web version has been downsized for a smaller screen and is essentially the desktop experience, only on mobile. If you have a strong Wi-Fi connection you won’t have any trouble with quick load times or the responsiveness of the user interface. The display is also smooth, with easy navigation and a seamless UX, making it easy to claim promotions, make deposits and withdrawals, and enjoy your favourite games, from slots, jackpots and table games, to the live casino.

Casino App

As of the writing of this STS casino review, there was no STS app for Android nor was there an STS app for iOS. Hopefully, this is on their future to-do list. In the meantime, while we wait for an STS casino app to appear, we can still thankfully enjoy a quality mobile experience via the web.

Banking Methods

UK players can choose from a variety of trusted STS banking methods, including debit cards, eWallets, bank transfer and prepaid cards. All payment methods available for UK players are in GBP currency. No credit cards are accepted for deposits, including eWallets funded by credit cards.


STS deposit methods include: Visa, Mastercard, ecoPayz, MuchBetter, Neteller, Skrill, PayPal, Trustly, Paysafecard.

£10 is the minimum STS casino deposit limit and £1, 200 is the maximum deposit limit. Deposits are instant and STS does not charge a fee to make this transaction.**


STS withdrawal methods include: Visa, Mastercard, ecoPayz, MuchBetter, Neteller, Skrill, Trustly, PayPal.

£10 is the STS casino minimum withdrawal amount and £20,000 is the maximum withdrawal limit. There are no STS fees for making a withdrawal.** As for STS casino withdrawal time, with the exception of debit cards (Visa and MasterCard) which process in 3 business days, all other withdrawal processing times are instant. That said, be advised that the casino pending time is 0 – 5 business days. Withdrawals are only processed once the casino pending time (the time in which you can cancel your withdrawal request) is over.

**Although STS does not charge fees for deposits and withdrawals, some payment providers may charge a fee. As such, be sure to check with your payment provider prior to making a deposit

Customer Support

STS casino customer support is available around the clock. In our experience with this casino, support was quick to respond via live chat and the customer service agent who helped us was friendly and knowledgeable. To get in touch with a human representative, you can use the following communication channels:

You will not find an STS phone number for telephone support. This is not surprising as many of the newer online casinos tend to not have this feature and focus more on live chat, email and social media messaging. Additionally, you can also investigate the company’s FAQ for answers. The FAQ is quite detailed and covers various topics like “Bonuses and Promotions”, “Payments”, “My Account”, etc.

UKGC STS licenses means that this is a trusted site as it must adhere to all the rules and laws that have been put forth by the UKGC, the United Kingdom’s governing body of gambling activities.

Final Thoughts

STS casino is a fantastic place to enjoy some of the best slots, table games and live casino entertainment online and on mobile. This fully secure, fair and responsible site features top games from some of the industry’s best providers. The only areas we feel it could improve is to add a VIP/loyalty scheme and create a mobile app. Beyond that, it has a lot to offer UK players with varying interests. We hope you found our STS casino review insightful and helpful. We recommend giving it a try on whatever device you prefer and taking advantage of their generous welcome bonus.
