STS, which is one of the few recognized fixed-odds bookmakers, has been registered in Malta since 2008. The brand operates under the parent company Vivaro Limited. The company is completely licensed by the Malta Gaming Authority, and it has additional regulation from the British Gambling Commission for their clients in the UK. STS's main product is sports betting. However, they also offer other kinds of betting, including virtual sports. The site has a live betting option, which is quickly becoming a favorite among online players. The site also features casino-type games, and they have a section for Live Casino gaming. They do not have a downloadable application at this point; however, you can reach a mobile version of the site easily enough on Android and iOS devices. They offer welcome bonuses and a lot of continuous promotions. Their site has a layout that is very visually appealing.
A welcome bonus of £10 is available for new customers who register at STS. When you make your first deposit, you must enter the promotional code "SBWB10". As with any welcome offer, there are a few stipulations that can be found below.
This is a limited-time, temporary offer. A free bet worth £5 on the tournament could be claimed by new customers. This offer was available only and exclusively during the basketball World Cup, which took place in August and September. After the offer expired, there ought to have been other bonuses tied to sports initiated shortly before certain predetermined sporting events. This is a promotion that has very much to do with the intimacy of a company with its customers and is mostly focused on the customer’s affinity with specific sports during certain times. It is an ephemeral promotion that lives and dies with the upsurge of interest in certain predetermined moments of a yearly calendar.
When one selection in a multiple bet with 6 legs or more does not win, the value of the bet is refunded to customers. This is a common concession, bet refunds for multiple bets with losing legs. But for other bookmakers, accas with five selections are allowed. This is a football acca, which means the bet must combine six or more football markets in an accumulator. The minimum stake is £2 and the maximum, £50. Each selection in the acca must be included at odds of 1.60 or bigger. What's more, this is a 100% matched bet bonus. That's because the refund equals the value of the bet. You have 14 days in which to use the bonus; all net gains resulting from the bet are yours to keep.
Clients utilizing STS at this moment can be rewarded with a £10 incentive that is tailor-made for placing bets on football. This promotion runs across the full span of the ongoing football season and has a few simple stipulations to ensure eligibility. To reap the rewards that this promo presents, you must first place a bet that has a total stake of at least £20. - The wager is a parlay and has at least two parts. Total odds at least 4/1 The total likely count of qualifying coupons is reduced, even if the choices and the chances somehow contrive to be correct, by the spacing of matches in the Premier League and Championship. This is the first aspect of the two-pronged strike against us. The second is that we get some slight increase in the odds when we are backing a team to win two matches (as opposed to win one). This counteraction of appearance increases the actual profitability unfortunately.
For qualification purposes, matches must take place on a Friday, Saturday, or Sunday, with both pre-match and in-play bets qualifying. The utmost bonus accessible every week is £10. When you require a bonus, you will uncover it in your account by the next Monday at 4 PM. For five days, bonus funds have no wagering requirements.
The STS Home Page Sports section presents offers and promotions tailored for both new and existing players. It has two main menu categories: In-Play and Sports. In-Play underscores the importance of live, in-game betting to this operator. The Sports page is less dynamic than the In-Play page and does not contain any performance links.
A customer may find a betting event by entering a word or phrase into a search box. Failing that, they can peruse a list of betting events organized not by the preferred ordering of search results but by hour (not shown). Alternatively, they can choose something from their Favourites list. The customer has a choice of roughly 50 sports to bet on, displayed in about as many distinctive betting events. Not all events are available in all markets. A betting customer of STS can just as easily place a bet on the outcome of a talent show as on the next match of an event in one of about 40 different kinds of regular summer or winter sports.
Currently, over 50% of the bets being wagered are on the sport of football. Customers can place match and outright bets across an extensive and impressive array of leagues and competitions from all over the world. Our vast betting catalog covers all the domestic leagues in Europe and South America, as well as many of the more obscure leagues and competitions from other continents. Hands down, the two leagues on which the most bets are placed are the English Premier League and the Champions League. Volume also tends to pick up when international competitions are taking place, especially in the summer months.
STS shows a typical three-way match result market for a football fixture. Under the headings listed below, customers can wager on as many as 300 additional markets that are displayed: ;headings of the extra match result markets ; match result, both teams to score, first goalscorer, last goalscorer, any goalscorer, etc.; What I like about this is that it ventilates the extra markets.
The outcome of a match (Home Win, Draw, Away Win) offers a market with a margin of over 6%. This is much higher than average. Casual bettors might not suspect a problem, but better-value bets exist with margins of 3% or lower. If professionals can score those in the match outcome market, they can also score them in the sub-markets for match-related prop bets.
STS customers have more options than just picking the main winner when it comes to betting on tennis matches. They can choose from a large number of markets and bet types, making tennis the second most popular sport, behind only football, in which to place bets. And before you say it, yes, we’re aware that betting on STS just might not be the best idea for your health, wealth, or relationships. But you have to admit that our friends in Białystok offer up quite a few intriguing ways to bet on a match when all is said and done. There’s just one small reason they might not be as lucrative as they first appear, and we’ll get into that in a second.
STS ranks as the third most popular betting operator for ice hockey. This is, however, a sport that does not see as much betting action as others. At least as of now. STS, which is based in Poland and operates extensively throughout Europe, has a thriving market in the UK. Despite this, STS does not offer betting on horse racing, a sure sign that they lack a strong customer base in the UK and Ireland. In any event, when the betting does take place, it is mostly on a few select leagues in Europe and the NHL, which is almost exclusively the most popular league in all of North America among gamblers. The Element of Chance: Bet Types STS offers some well-liked opening markets to bet on ice hockey. These include the result of the match, the total points scored, and a type of bet called 'handicap betting,' where one team is given a pretend disadvantage. But beyond that, there's not a lot of depth to ice hockey betting with STS.
Alongside the previously mentioned markets, STS provides a host of betting options that are much more varied. The bookie covers events from the world of badminton, motor racing, snooker, mixed martial arts, and table tennis. Furthermore, it is an excellent option for punters that want to place a bet on two very popular British sports — golf and cricket. Outside of football, esports, and tennis, these two sports receive by far the most in-depth coverage at STS. Whether it's a Test match, a One Day match, or a T20 cricket match, or a tournament from the men's or women's golf tour, STS has all bases covered.
STS developed and launched an app for iOS and Android devices that can be downloaded onto the devices. But ESports can be accessed from mobile phones and tablets, if the browser is optimized for mobile, just like the site can be accessed through a PC. The mobile site is as functional and good-looking as the main site. There are no special deals set aside for mobile users, and all this just speaks to the equality of the user experience across the platforms.
STS is a classic online bookmaker with fixed odds, and it is neither a betting exchange nor a spread betting firm. Therefore, this operator provides the following standard services associated with a bookmaker:
The in-play betting option is the primary selection on the main menu of the STS Home Page. When this option is selected, the user is taken to the in-play page of the book, which illustrates that there are about 15 sports in which STS is currently offering in-play betting. The two primary streams of in-play betting for STS customers would appear to be unaffiliated football and unaffiliated tennis. These two options allow STS to illustrate the availability of, at any given time, towards 50 different betting lines that can be rendered on a single unaffiliated football match at the same time. STS does not appear to have the necessary rights to offer live streaming for its customers.
A person wishing to bet can examine real-time gaming data just before making a wager. If a significant event occurs—like a goal in football or a service break in tennis—the odds are suspended.
STS is one of the many online bookmakers that allow customers to cash out bets during a live event. The bets that count can be placed in pre-match markets or earlier during the live event. The purpose of cash-out betting is to help you guarantee a profit (if the outcome of the fixture matches your wager) or limit your loss (if the outcome of the fixture doesn't match your wager and you don't want to continue holding the losing bet). In both cases, you benefit from the cash-out offer if you take it before the bet has a chance to.
STS offers customers the means to easily transfer money in and out of their betting accounts. The company supports several methods that customers can use to fund their accounts. When it comes to withdrawals, the same options tend to apply. Again, STS supports a standard range of methods. In general, the funds flow quickly, though in some cases the customers might have to wait a few days.
Individuals interested in the service can visit the STS main site and click on the 'JOIN' button. Among the various online betting platforms, this one has a comparatively simple process for setting up a new account. A prospective bettor is asked to select a Username and Password that are unique to this platform. Though not a requirement, there is a spot to enter a promo code. After entering some requisite information and fulfilling the demands of the form, the new registrant assumes the persona of a customer. There is also this pesky little legal matter that must be dealt with: All users must accept the Terms & Conditions of the service to be eligible to place bets.
First-time customers must make an initial deposit. The minimum required is 310, and there are absolutely no fees. Depositors select a method and supply the amount. STS always has its hands wide open to receive payments within the limits just specified. The operators can, at their discretion, accept anything over that limit. Once the transaction is in the system, the account balance updates. At that point (and that point alone), a brand-new customer can make any type of bet.
The specific market is clicked by bettors, and the odds are highlighted. The Betslip emerges with the particulars of the wager. Customers can now explore and pick from a bewildering array of more than 200 options—an 8-fold increase in just a year, and mostly thanks to our own Swiss Army Club Development team, whose name says it all. Bets are placed, and should the customer be on the right side of the outcome, there's a not-undesirable update coming for their account: some 10% more than the original stake, thanks to our margin.
An extensive FAQ section exists for the customers to peruse, and they can also look up the particulars of the detailed rules that govern the various types of bets they can make. As for customer support, there are only two methods by which a customer can get in touch with the support team. One method is by sending an email, which, unfortunately, surfaces a couple of problems. First, there is no indication as to how long a customer can expect to wait for a reply. Second, the email support is far less effective than if the team provided either telephone support or a Live Chat option.
STS operates with a full license from the UK Gambling Commission, which should reassure UK punters about just how trustworthy they are. A series of security measures are in play too, with the bookie having recently gained an ISO/IEC 27001:2013 certificate, which helps to prove their reliability. Meanwhile, the bookie is also linked with IBAS, who help to deal with betting disputes and have a fantastic reputation within the industry. The STS privacy policy is available to be viewed at all times, however the bookie does not provide details surrounding the use of Secure Socket Layer (SSL) encryption technology or firewalls.
Since 2008, STS has been functioning as it does today. It has a small but faithful group of bettors. These bettors virtually have no presence in the UK market. If you try to sign up with them, it is welcoming enough, but the offer is so insignificant that who even knows what STS is trying to accomplish by having a sign-up offer? The way STS carries out its business makes actual features and value far less important than word-of-mouth and the recommendability that comes from it.
A bookie that is often in the news is STS, and their most recent headlines are as follows:
The Polish Bookmaker Awards held their second annual ceremony in March this year, during which STS took home a cornucopia of awards. STS, together with Fortuna, won 8 of the 11 honors doled out that night, while Fortuna was named the Best Polish Bookmaker and won at least one award for a social campaign (in this case, for a stunt where they gave out 0.30 euros to fans attending Polish Second Division matches).

Concurrently, STS seems to be managing the pandemic better than some competing bookmakers, with its owner and Chief Executive Mateusz Juroszek expressing optimism about growth and expansion. STS, which claims to have 50% of the market share in Poland—up from 31% in 2018, according to Publicon—and which appears to be one of the better-performing operators in that country, seems to possess a sort of technological edge in the rapidly transforming betting industry. That edginess translates to a robust online betting operation that seems to have around 1 million online users across several European markets.

Information from Poland's Ministry of Finance show a 10% decline in gambling revenue for the first half of 2025. Yet, even with this seeming stagnation in the betting business, STS has managed to bolster and extend its lead. The bookie now commands a 50% market share all by itself. That figure is surely helped along by the fact that the Polish government's own taxation policies—which STS complains about—have shrunk the betting market since 2017.

How long does withdrawal take on STS?
At STS, the timeframe for payouts is set from 1 to 3 working days. If you're withdrawing your funds using PayPal, Skrill, Neteller, or Much Better, you'll likely see your money in less than 30 minutes. But if you're using Visa, Mastercard, or a direct bank transfer, you might experience a waiting period of 1 to 2 days before you see the money in your account.
Agreed. STS has a full set of licenses and is governed by the Gambling Commission. So while it may not be the most well-known company in the bookmaking space, it is nonetheless a safe and dependable option for UK customers who want to sign up and place wagers. And judging by the customer reviews we found, it also has a pretty solid reputation.
At STS, you can cash out from select sporting events and markets—think of both as opportunities to bet that tend to come before a game as well as during it. Cash outs, in one form or another, are able to be utilized on the following types of bets: single; combo; system; and prematch bets that you have placed on either a market or an event that is still in play.
Creating an STS account will first require potential customers to click a button in the upper right corner of the page that says "Join." After that, it is imperative that customers fill out the registration forms with accurate and complete information. This means that they must provide their full names, working email addresses (which are set up to receive emails), and dates of birth. They must also opt into any descriptions of available promotions that are listed on the main site—basically volunteeing to receive ads.
At STS, it takes 1 to 3 business days to process withdrawals. If you use PayPal, Skrill, Neteller, or Much Better, however, you'll get your winnings in under 30 minutes. As for Visa, Mastercard, and bank transfer customers, they can expect their funds in, you guessed it, 1 to 3 business days.
The STS bookmaker mainly covers Europe, although it holds a license to operate in the UK. It simply is not in competition with traditional UK betting brands. But what is it that STS does that is better than any other betting operator? It is hard to put a finger on this, and in fact, we might be better off just acknowledging that STS does not have any one big thing going for it. The company covers about as many markets as you can find for both pre-match and in-play betting. And live betting? Well, it is hard to avoid it when looking over the STS site.
