18+/Applies to new UK Customers who will place first bet, in first 14 days, on any sports with 3 selections; min £5 – max £30 stake. The Sports Welcome Bonus paid as bonus money with withdrawal limitation (wager with min 1.8 odds). 14 days for using bonus. Deposit provider limitation. T&C apply.


STS is operated by a company called Vivaro Limited which was founded in December 2008 and also owns the Vbet online sportsbook. Vivaro is incorporated in Malta and the registered is St. Julians in that country. STS through Vivaro is regulated by the UK Gambling Commission and licence information is available for the public to assess. STS is trying to gain market share in the UK market but is competing against a number of trusted and established brands. However, the Gambling Commission must believe the operator deserves a licence which is reviewed at regular intervals. Malta is a reputable location for gaming companies.

STS offers sports and casino gaming to customers in Polish and English. The operator focuses on in-play betting and offers over 30,000 live events each month. The site has been awarded certification for Information Security which means customers know personal data is secure. STS offers a comprehensive sports betting service both pre-match and in-play. 

Breaking into the UK market is difficult and this review will examine some of the strengths and weaknesses of STS. Some elements are missing from the site but these should be implemented in the fullness of time.  Customers can take advantage of a welcome bonus which is described below.


New Customer Bonus

Customers who register with STS can claim £30 in the form of a welcome bonus which is subject to the following terms and conditions:

18+/Applies to new UK Customers who will place first bet, in first 14 days, on any sports with 3 selections; min £5 – max £30 stake. The Sports Welcome Bonus paid as bonus money with withdrawal limitation (wager with min 1.8 odds). 14 days for using bonus. Deposit provider limitation. T&C apply.

  • New customers in the UK.
  • Complete the registration process with STS.
  • Make an initial deposit of £5 or more.
  • Place an accumulator with three selections or more with a stake of £5 to £30.
  • The bet must be settled within 14 days of registration.
  • The bet must be placed at odds of 1.8 or bigger.
  • The free bet token is a 100% matched bet bonus.
  • The free bet value cannot be withdrawn.
  • The free bet is valid for 14 days.

The free bet is for a modest amount but the qualifying requirements are achievable within a reasonable timeframe. However, other welcome offers stipulate single bets so the requirement to place a multiple with three selections or more is a negative. 

At least three selections must take part for the welcome offer to apply and certain deposit methods do not count for the qualifying deposit. Bets placed using the free bet token cannot be partially or fully cashed out. The value of the free bet token is not included in any winnings from the free bet.  

Mobile Exclusive Sign Up Offers

At the time of writing STS does not offer a downloadable app. Any operator in the UK market would be expected to have a mobile app version so STS are expected to launch one in the near future but this has not been confirmed.  However, STS does have a mobile site which is easy to navigate and provides a smooth interface. Customers can open an account on the mobile site. However, there are no mobile exclusive sign up offers but new mobile customers are entitled to £30 in the form of a free bet token and dynamic concessions for existing customers.


Customers with STS using desktop computers and mobile devices can benefit from the following ongoing promotions:

STS App Features

The STSBet betting app offers customers all the features of the website including the following:

In-Play Betting

Customers with STS have many in-play betting options and there are over about 1,000 live events each month. The most popular live betting sports are football, tennis, ice hockey and basketball. In-play events are displayed in an Overview, Event View and Multi View. A calendar displays upcoming live betting options for the current week.  

There is no live streaming but in-play bettors can refer to a visual representation of the progress of play. The live interface does not show derailed live statistics but just the basic scoring for each sport. Betting is taken down when there is a significant event which causes price fluctuations such as a goal in soccer or a break of serve in tennis. The betting options are fewer than in pre-match betting but all the most popular basic markets are covered.   

Live Streaming

STS does not provide live streaming of sporting events. However, the in-play interface features a graphical representation of the action. Customers can refer to a limited range of live match data before placing a bet. Betting is suspended after a key event such as a goal in football or break of serve in tennis. The lack of live streaming is a negative and several UK-facing competitors live stream numerous events in football, tennis and other sports.  STS could introduce this facility in the fullness of time but the current interface is not suited the live streaming of betting events.

Acca Betting

STS offers customers acca insurance for football multiple bets. This promotion is subject to the following Terms & Conditions:

  • Qualifying accumulator bet with six selections or more.
  • Football pre-match and in-play markets.
  • Stake from £2 to £50.
  • Each selection must be backed at odds 0 3/5 (1.60) or bigger.
  • If one selection loses, the refund is for 100% of the stake.
  • Refund comes in the form of a Bonus Bet Token.
  • Bets must be settled within 14 days of placement.
  • STS general Terms & Conditions apply.

Several of the leading UK brands provide this acca insurance promise. Customers with Paddy Power are credited with a free bet if they have one loser in a four-team accumulator. At the time of writing Ladbrokes and William Hill do not offer acca insurance on football. Typically, acca insurance means a free bet for a minimum and maximum amount when there is one losing selection in a multiple bet. STS stipulates a minimum of six selections while some competitors return the stake for accas with one losing selection from four or more legs. Customers with STS can combine selections in single line singles, doubles, trebles and accumulators and system bets that combine selections in permutations. 

Cash Out

Customers with STS can cash out bets during a live betting event.  A dollar sign icon alongside the market indicates if cash out betting is available. STS allows bettors to cash out bets across a number of sports, including football and tennis, and betting markets. The facility is being added to more sports and options over time. Live bettors decide to cash out to ensure a known profit regardless of the final outcome or limit the loss from a losing bet.  Pre-match bets and bets placed earlier in a live event can be cashed out. The value of the cash out offer from the bookmaker depends on the stake and odds of the original bet and the odds when the request for a cash out offer was made. 

Deposit Options

Banking methods with STS includes the most popular options including credit and debit cards, e-Wallets and Bank Transfer. The time delays vary by method but deposits are usually immediate. Most deposits do not carry a fee but there could be a charge on some options. Some deposit methods do not count for qualifying deposits for the welcome bonus. 

The site documents the rules and customer service staff can help players with questions. However, as STS is new to betting in the UK the customer services department is still being built with qualified staff. There is no live Chat and banking queries can be sent using the contact form.

STS offers betting on over 100 countries and many leagues and competitions. The popular leagues are La Liga in Spain, Serie A in Italy and the Bundesliga in Germany but the league that attracts the most betting interest by far is the Premier League in England.

The third most bet on sport by quantity is basketball. STS has odds for about 20 leagues, mainly in Europe. However, by far the most popular league is the NBA in the United States, which is the most lucrative competition in the sport. In addition to the two-way match result market customers can place wagers on about 80 other markets under the headings of Match, Quarters, Halves and Players. Outright betting is available on future events such as the NBA champions. Basketball is also very popular for in-play betting due to fluctuations in the simple scoring method.

American Sports

Customers with STS can bet on the following US Sports professional leagues


Basketball – NBA

Baseball – MLB

American Football – NFL

Ice Hockey – NHL


College fixtures in these sports are also popular for betting. The match winner, handicaps and totals attract most betting interest. Customers can bet on player and team props and more exotic markets such as the correct score. STS offers ante-post betting on the winners of leagues, conferences and championships for the four US betting sports. The Superbowl is by far the most popular standalone event for betting. The match determines the NFL champions in American Football. There are post-season playoffs in basketball, baseball and ice hockey.  Soccer, tennis, golf and horse racing are global sports which serve the European and US markets. 


Esports is a relatively new area of sports betting and it involves bets on video games. There are now professional leagues and when STS operate purely in Poland Esports was covered. Customers can bet on games like Counter-Strike and League of Legends in events in the main Esports leagues. Odds are available in pre-match and in-play betting. Betting options include the match winner and map winner which are segments like sets in tennis. The main betting markets have two options as there is no tie for the match and individual map winner. 

Politics And TV Specials

In addition to the regular sports, customers with STS can place wagers on Politics and TV Specials. The Presidential Election in the united States and the general Election and Brexit in the UK attract the most betting interest. STS offers odds on the outright winner of reality shows and awards.  The most popular TV markets are related to Strictly Come dancing, I’m A celebrity and the BBC Sports Personality of the Year.  STS also provides betting markets for the winner of awards.


Customers can refer to statistics before placing a bet. For example, there is plenty of data from matches in the previous round of the Champions League. There are records for Over/Under totals and handicaps from the group stages and knockout rounds. STS provides detailed statistics for most sports including football, tennis and basketball.

Customer Support

Members with STS can contact the customer services department using an email form.  There is no Live Chat or telephone support but customers can use a generic email address to get in touch. The response times are between 24 and 48 hours. The limited customer support options are a negative and other operators provide more contact methods. The site does feature a comprehensive FAQ section covering account management and betting functions. STS is committed to promoting responsible gambling. The site has banner links to support bodies and there are exclusion processes in place for problem gamblers.  Customers can limit daily and monthly deposits.  Customers can discuss betting related issues on the STS blog. This facility also includes match previews and tips.


STS is operated by Vivaro Limited, a company licensed and regulated in Malta. UK customers place bets under the licence and regulations of the UK Gambling Commission.  The UKGC is one of the most respected regulatory bodies in the industry. STS must have shown criteria for free bets and promotions. The operator has met the standards of compliance set and monitored by the Commission in Great Britain. The STS is safe and secure and the use of personal data complies with the latest regulations. The privacy policy protects the personal data of customers.

About STS

STS were originally online bookmakers based in Poland which explains why the site can only be reading Polish and English. Customers in Poland bet on a wide variety of sports and events and as part of the move into other parts of Europe the operator will offer a varied and comprehensive sportsbook. The site offers more than the standard sports and leagues which is a departure from the normal sportsbook targeted at the UK market. STS has a market share of 49% in Poland where online bookmaking is regulated and taxed and has entered new markets to build on that success. This experience will be applied to the UK where STS know how to serve their audience. This company is the official partner of the national football team of Poland. 

Bottom Line

STS is new to the betting markets outside Poland and there are some significant missing features. There are not too many ongoing promotions or live streaming. The dynamic promotions for existing customers are limited and there is no mobile app that can be downloaded for Android and iOS devices. The range of sports and markets is one of the best in the industry and the welcome offer is achievable. Once those missing features have been introduced STS will be a first-class betting site.
