STS UK Review (2024)

The UK gambling industry is booming with new entrants, and none has caught attention like STS. While STS might seem like a new betting site in the UK, it was established way back in 1997 in Poland.

First starting as an offline sportsbook, STS has expanded its operations into online gambling services with licensed operations in UK, Estonia, and Poland.

Known for building a solid reputation, STS is the official sponsor of the Polish national team. Besides, it has Peter Schmeichel – Manchester United’s legendary goalkeeper – as its brand ambassador. The company is also known to sponsor several clubs in the Polish top-flight league, including Lech Poznan.

Besides the UK, the bookmaker also accepts players from Canada, Finland, Estonia, and Poland. While it may not be a big name here in the UK yet, STS is quite successful and popular back in Poland. As it continues expanding into the European market, STS is steadily growing into a promising international industry leader with its sports and casino gaming services. They have more than 300 football markets and continuously growing the list of sports offered. 

Suppose you wish to try out the amazing live casino or sports betting experience on STS. In that case, you’ll be happy to know that they have a welcome bonus and easy navigation, among other exciting features. There is a lot more to this bookmaker. This review highlights the gaming markets, odds, margins, limits, payment options, and basically everything you need to know to decide if STS is a competent gambling service provider. 

Ease of Use

The most basic feature of a betting site is the user interface. STS has one of the most simplistic layouts among the many betting sites we’ve reviewed. This layout makes it easy to navigate, especially for new users.

The main screen of the online platform has three sections that lead you to the Live betting section, Highlights and Starting Soon. The quick navigation buttons at the top of the STS screen make it easy to access sports, casinos, live casino, in-play, virtual games, and esports categories. 

There is even a blog that gives players excellent gambling advice and tips. You can easily access it from the More button. This button also directs you to Betgames, another option of casino gaming experience provided by STS. 

If you already know the games you wish to bet on, STS has a handy search feature that lets you pick out the exact event you want to bet on. 

STS Sportsbook Review

STS is excellent in the sports betting world because of the wide range of games that you can bet on. UK players will be disappointed, however, that despite the wide range of events available for betting, STS does not offer horse racing betting, a popular sport in this region.

That aside, STS will provide you with a gaming experience in popular and obscure sports. If you thought you couldn’t bet on WWE, table tennis or futsal, then you haven’t been on the STS betting platform.

Striving to be the one-stop shop for all matters of sports betting, STS offers an unimaginably high number of football betting markets. You’ll be amazed to find more than 350 different options you can bet on a football event. This great offer of options extends to other sports such as basketball and tennis.  

In-play Betting and Live Streaming

Betting on an event while the action has started provides a thrilling experience for many gamblers who find it strategic. Watching and analysing how a game flows before deciding to put your stake on a particular outcome might provide you with an edge.

STS provides in-playing betting by clearly showing players the events that are currently live so you can bet on them. They’ve even thrown in a cool feature that allows you to list favourite events, making it easier to locate them later. The multi-view option will enable you to bet and follow these events simultaneously – you can follow up to 3 events simultaneously.

Unfortunately, STS does not have the streaming rights for many popular sporting events, so you may have to rely on a different application for live streaming. 

Multiple Bets, Accumulator Bets and System Bets

Do you fancy multiple bets? The good news is STS enables you to place a multiple bet of up to 50 events. This is extremely high, considering most betting sites have a maximum limit of 20. 

What’s more, if you fancy multiple bets, you probably wouldn’t pass a chance for accumulator bets. Accumulator bets are a great way to boost your odds from single to double or even triple digits. Placing accumulator bets on STS is pretty simple – the platform also offers systems bets, System-Trixie, offering 2/3 and System-Patent bets. Chain bets are also a popular alternative on the betting platform. 

Minimum and Maximum Bets When STS Betting

Like many other sports betting sites, STS has a minimum allowable betting amount. The lowest limit you can bet with is £10, which is lower than the average of £50 that other platforms require. It is thus highly affordable to all sorts of gamblers. 

It's hard to determine the maximum bet on STS since different sporting events have different higher limits. The Premier League, for instance, will give you higher betting limits compared to betting on a regional handball tournament in France. 

Betting Odds, Margins, and Value

The betting odds on STS vary significantly between different markets. A clear example is the tennis match between David Metz and Tyler Mercier which put a Metz win odd at 9/1 and a Mercier win at 1/50. This puts the bookie’s profit margin at 91.97%. 

Just how varied is this profit margin across different sporting events on this platform? Let’s compare the above margin with the odds posted for a darts game pitting Boris Koltsov against Martin Adams. The odds for a Koltsov’s win were 87/100 against 10/11 for Adam’s. Calculating the profit margin, we get a return of 95%, which is considerably higher than tennis. 

We can’t forget to compare the odds for football events since the majority of the gamblers in the UK have popularised football betting – the most common market is the Over/Under. The Over/Under odds for several EPL matches gave an average return of 95%. 

Odds for other events varied as follows: 

  • Golf: 92% - 94.52%
  • Rugby: 93% - 95.6%
  • Boxing: 91.29% - 94.37%
  • Basketball: 89.67% - 93.06%

There was a minimal variance between different Over/Under score lines, with the 0.5, 1.5 and 2.5 options having a return to player of 94.87%, 93.69% and 94.45%, respectively.


The cash-out feature is among the interesting things that have got this bookie growing in popularity. Today, most bettors opt for the cash-out option, especially for highly unpredictable outcomes. 

STS cash-out amount depends on the odds at which you placed the bet and the stage the event has reached. The closer the game nears the end, the higher the cash out amount. 

Sportsbook Promotions

STS has a series of bonuses and promotions for sportsbook betting. These include £5 in cash for bettors who place a qualifying bet of £20 on single or accumulator bets with minimum odds of ⅘ – whether their bet wins or losses. To receive the full bonus of £50, you’ll have to repeat the same process with a qualifying bet of £100. 

Other offers include:

  • Weekly £10 English Football bonus to be pocketed if a winning bet of £20 is placed on an EPL or Championship game played between Friday to Sunday with total odds of 4/1. 
  • Extra 6. This is a 100% refund of a stake of not less than £2 and not exceeding £50 of an accumulator bet of 6 events that loses by a single event. 

STS Casino and Live Casino Review

Many sports betting platforms are diversifying their niche to attract more players and grow their income. There is no better way of diversifying than offering online casinos. STS’ online casino treat is among the top in the industry – the platform provides every customer with a chance to win a welcome bonus of £250 and 100 free spins.

The striking difference between STS and other online casino platforms is that you don’t need a code to collect your bonus on STS. But as always, there’s a catch to getting the free bonus, and that is, you can only use your free bonus on specific games. You must also comply with the minimum deposit condition. 

Live Casino Game Selection

The live casino game selection offered by STS will leave you completely satisfied and hooked to the platform. For a fully immersive live casino gaming experience, STS also offers live dealers. 

The STS live casino offers you a real-life casino experience with the following games on offer: 

  • Blackjack
  • Roulette
  • Football Studio
  • Side Bet City 
  • Baccarat
  • Ultimate Hold’Em
  • Deal or no Deal

In addition to the live casino games, STS has another gaming variation that you might find captivating. To kill the monotony of the popular casino games, STS gives you the chance to try out bet games such as include:

  • Dice Duel
  • War of Bets
  • Speedy 7
  • 6+ Poker
  • Baccarat
  • Bet on Poker
  • Lucky 7
  • Wheel

The bet games also come with a live dealer; thus, STS does not compromise on the gaming experience for its players. 

Casino Promotions

Most of the promotions for sports betting on STS are also extended to casino players – although the figures may vary slightly. The welcome bonus can go as high as £80 on some of the best casino games the market has to offer. 

STS Mobile Betting

At the moment, UK players will have to contend with using the web version of the STS sports betting and casino platform since there are no mobile betting apps for this version. The only mobile version ever launched is only available for gamblers in Poland. 

However, the good news is that you can use the web version on any device since it has been optimised for mobile devices as well. Placing a bet is just the same whether you use your mobile phone browser or a desktop browser.

STS Payment Methods and Limits

The payment methods accepted by STS accommodates virtually any player, especially since most of these options are common in the UK. The payment process has been simplified to make it hassle-free and favourable even for first-time gamers.

STS offers the following payment options:

  • Skrill
  • Neteller
  • EcoPayz
  • Visa
  • MasterCard
  • Paysafe
  • Sofort
  • Zimpler
  • MuchBetter
  • Rapid transfer

Depositing funds into your STS account using any of the above-listed options will only take seconds and utmost a few minutes. However, withdrawing your winnings using these options varies – it takes an average of 3 days before funds can reflect in your wallet.

The lowest deposit to be made into your STS account is £10, while the maximum is £10,000.

Customer Support

STS has put a lot of emphasis on its customer support system. It is not difficult to see why since addressing your customer’s concerns can make or break an online business.

Even though average bettors rarely require customer support, it is still essential to know how to reach the resourceful personnel at the company. 

STS offers the following customer support options:

  • Live chat
  • Email
  • Phone

The customer support staff at STS are polite and attend to your concerns promptly. English is among the two supported languages, the other being Polish. The 24/7 customer support is highly responsive to customers with minimal waiting times on the telephone lines.
