We already know that STS is a trusted brand, as it is one of the biggest in Poland and across Europe. And we’re pleased to see that the online casino meets the same high standards as the sportsbook.

STS Casino Welcome Bonus

STS Casino offered a deposit cash bonus at launch, though now offers a free-spins-only welcome bonus instead. Whilst it isn't as impressive, it does offer you some extra chances to try out games for free.

The bonus terms are quite favourable if you’re a slot player. If you have a passion for table games, you’re better of checking the similar UK casinos listed below this STS Casino review or in our dedicated casinos page. Nevertheless, slot players will definitely enjoy the casino game library provided at the STS casino section, and this bonus is a perfect addition. 


STS Casino Bonuses for Existing Players

Unfortunately, there’s no mention of any bonuses or promotions available to already registered players. We checked both the UK and the International site, but not a single word on reload bonuses, free spins for existing players, or anything of that kind.

However, there was a big banner for tournaments. Although not much, there are some extras for registered players. Tournaments have gotten a lot of flack from a responsible gambling point, but it appears they are still available. Note, the tournament involved slot games. You can find more details regarding prizes, eligible games and tournament schedules on STS casino's Website, since they change constantly.

There could be bonuses which are not publicly available, meaning you get the offer via newsletter, or on-site notification, which is why we recommend subscribing to the newsletter when you register with STS Casino. The moment we get more information on the reload bonuses and promotions, we will make sure to update our review.

Is STS Casino Safe?

STS is a new name in the UK, but it’s definitely trusted in the gaming and betting industries. For one, it’s made a lot of noise in the Polish market, sponsoring the National Football team, and a bunch of other football clubs there. In addition, with the UK Gambling Commission license (Ref. No. 54498) , they can now access the UK market, and entertain UK casino players. In our view, this is the best “seal of approval” a casino can get, ergo, STS Casino is as safe as an online casino can get. They are obviously trying to get a lot of attention with the sponsorships. It’s not a white-label casino that wants to stay under the radar, which a lot of them do.

They are also associated with IBAS, which basically says they are open to resolving disputes even via 3rd party platforms. In addition, they are promoting responsible gambling by showcasing the seals of GambleAware and their now popular GamStop campaign. However, by far the most important “safety net” is the UK Gambling Commission seal of approval.

All sections of the website are secured with SSL encryption, guaranteeing your private information is kept safe.

Lastly, STS, besides promoting responsible gambling agencies, they also offer some really useful self-imposed player limits such as:

  • Deposit Limit
  • Wager Limit
  • Loss Limits
  • Self-Exclude
  • Account Closure

The wager and loss limits are very welcome, and not common even among leading UK brands. In this regard, STS Casino deserves our full praises and makes for a safe gaming environment to customers.

Payment Methods and Withdrawal Policy

As of 14th April 2020, players from the UK are no longer allowed to make credit card transactions at online casinos

STS has two different websites where you will find different payment methods, one of which is dedicated to the UK betting community. Nevertheless, they accept a decent variety of payment methods, covering most bases. However, we are worried about bettors from Canada and New Zealand that might want to give STS a go. At this moment, however, there are no payment options that fit these markets, besides the debit cards and the standard set of e-wallets such as Skrill, EcoPayz and Neteller.

STS Withdrawal Policy and Limits

Payment MethodWithdrawal Time*
Credit and Debit CardsUp to 3 Days
SkrillUp to 24 Hours
WirecardUp to 24 Hours
ecoPayzUp to 24 Hours
NetellerUp to 24 Hours
TrustlyUp to 24 Hours
MuchBetterUp to 24 Hours

*Withdrawal timeframes can be extended pending verification procedures such as KYC, source of funds, payment method verification. 

STS Casino does not charge transaction fees, regardless of payment method and if you're making a deposit or a withdrawal. 

Transaction Limits:

  • Minimum Deposit: £10
  • Maximum Deposit: Depends on Payment Method
  • Minimum Withdrawal: £10
  • Maximum Withdrawal: £10,000 per transaction


Games Lobby - User-Friendly and Great Choice!

We cannot but mention that the STS Casino comes as complementary, second in priority product. The focus is on the STS sportsbook, but this shouldn’t discourage you from joining them. The STS Casino features a simple, easy to use interface, which can take you to great distances.

Instead of quantity, UK casino players are greeted with handpicked quality games, coming from the studios of Yggdrasil, NetEnt, iSoftBet, Microgaming and the subtle, yet prominent Thunderkick. Players from other markets have the opportunity to enjoy casino games produced by a few other casino game providers, namely Playtech, Gamomat, Kalamba, Oryx, and Play’n Go among a few others. 

Filter wise, they’re getting there. You can see the newest slot games like Imperial Riches, Royal Gems slot, Nikola Tesla’s Incredible Machine and Rise of Dead slot, next to Butterfly Staxx 2, Break da Bank, Gonzo’s Quest and Immortal Romance gives you an idea of how much the games have evolved over the past few years.

Besides slots, players can enjoy table games and video poker. Overall, it’s not an overwhelming game collection, rather one that covers the basics.

You can filter the games by providers, category and you can use the search box, which is almost hidden next to the Favourites symbol, represented with a heart.

Available Games
  • Keno
  • Blackjack
  • Video Poker
  • Slots
  • Jackpot Slots
  • Table Games
  • Roulette
  • Craps
  • Baccarat
  • Live Dealer Blackjack
  • Live Dealer Roulette
  • Live Dealer Baccarat

STS App for Casino Players

If you liked the interface on the desktop, then you are going to love the STS mobile app. Those handy game filters we mentioned in the casino games section, they are also available on mobile.

Players won’t need to waste time scrolling through long lists of slots. Evolution’s live dealer games are also available to play on mobile devices.

At present, there is no native STS Casino app to download. IOS, Android and all other mobile users are able to play instantly via the mobile site. Load rates are just as good on their web-app though. We would, however, suggest that you ensure you have a strong internet connection. Keep that in mind and STS mobile casino might be even more enjoyable than the desktop version!

STS Live Casino

Apparently, the live casino plays an important role at STS Casino, so much so that it has a dedicated section. However, despite this, there don’t seem to be any exclusive, branded casino games. Then again, you have the full Evolution Gaming arsenal at your full disposal.

This includes, but is not limited to Lightning Roulette, Monopoly Live, Side Bet City, Live Bet on Poker and Live Dealer Blackjack.

There are other games, but we liked to focus on the aforementioned. If you are at STS for the sportsbook, then you will surely enjoy the Football Studio Roulette. Nothing beats playing roulette and having a chat with other roulette players about the upcoming or the match that just finished. Socialising makes casino games twice as entertaining and you have somebody to talk to if the ball is not in your favour. All in all, STS Casino's live dealer lobby matches most UK market leaders. There would be nothing to set them apart from the likes of bet365 or LeoVegas if they had branded tables. One for the future, for sure. 

STS Casino VIP & Loyalty Rewards

If we haven’t already put this point across, STS is new. A lot of their efforts have been put into attracting new customers. An excellent interface, attractive welcome bonus and quality casino game lobby; this has been their main focus. Unfortunately, though, not much has been done for the STS Casino VIP Program. In fact, at the time of writing this casino review, there was no mention of a VIP Club.

Something tells us that as the online casino starts to grow, this may be the next thing they look into. That or some other form of STS Casino loyalty rewards system. High esteemed players deserve to be treated often and we are sure that STS won’t be leaving their VIPs empty-handed. The casino is aiming to compete with the big dogs after all!

Customer Support

If we have to be honest, STS’ approach to customer support can seem disappointing. If you do have a query, the first section you’ll be directed to is their basic FAQs section. The fact that they do have this page is already more than most. Nevertheless, reading through the information won’t get you very far. There are only a handful of questions and very little content. Your only other option is to get in touch via email.

STS live chat for ALL visitors is definitely something the casino needs to look into if they want to be competitive. The good news is that they do have a live chat available 24/7 for registered players. It's a start but we definitely think that unregistered users should benefit from the same treatment.

Of course, phone support would really seal the deal, but at this moment phone support is not available. Overall though, we only have minor nit-picks regarding customer support. For most players, 24/7 live chat is all that's needed. And as a plus, STS Casino's support agents are friendly and up to the task of handling complex player queries.

STS Casino – Hoping to Make it in the UK!

STS has been big in Poland for quite a while now. Earlier this year, the casino site took the decision to move into several European markets. The list of accepted countries is still rather bleak, but this isn’t necessarily a bad thing. Fewer feature markets means that they have more time to focus on the regions they do accept traffic from. STS' UKGC license means that they have opened their doors to players from the United Kingdom.

They don’t just accept players from here though, they welcome them with open arms.

GBP is of course accepted and they even have a UK specific casino site. Let’s not forget that STS is a PayPal Casino; that should keep British players happy!

They’re big in the UK but STS also has a separate casino for their other feature markets. Players from the likes of Germany, Slovenia and of course Poland are made to feel just as welcome. They haven’t put all their eggs into one basket but they’ve still kept things simple.

No. At present, there is no native STS app available to download. IOS, Android, Windows and any other mobile users are able to play instantly.

If you're a new player looking to sign up to the online casino, then there's a hefty welcome bonus ready to snap up. The good news is that you will need to enter the promo code to be eligible.
