Superbet / Counter offer

STS is a traditional fixed odds bookmaker that has been registered in Malta since 2008. The brand operates under the parent company of Vivaro Limited. STS is currently licensed and regulated by the Malta Gaming Authority. The bookmaker is also regulated by the British Gambling Commission for customers located in the UK. The core product is sports betting but the site also features a casino and live casino. At the time of writing, STS does not offer a downloadable app. However, customers can access a mobile version of the website using Android and iOS devices. The bookmaker offers a welcome bonus and ongoing promotions for current players.

STS Sign Up Offer

STS is licensed and monitored by two of the most respected regulatory bodies in the industry. The UK Gambling Commission in particular has introduced stringent standards of compliance. Operators who serve the UK market are required by license to offer realistic and transparent welcome bonuses. STS have a welcome offer of £40 in the form of a free bet. This bonus is subject to the following Terms & Conditions:

  • New customers only and current customers are not eligible.
  • UK facing offer but other countries and currencies apply.
  • Minimum deposit of £10.
  • Qualifying accumulator bet with two options or more.
  • Stake from £10 to £40.
  • Placed within 14 days of registering.
  • Minimum odds of 1/2 (1.50) for each selection.
  • 50% matched bet bonus up to £40.
  • Any returns do not include the free bet stake.
  • 6x wagering with bonus on min odds of 1/2 (1.50) before withdrawal.
  • STS general Terms & Conditions apply.

The STS welcome offer is a realistic 50% matched bet bonus. The value of the free bet token equals the value of the qualifying bet. There are no turnover requirements and the odds restrictions are not too stringent. However, similar offers with other online bookmakers allow singles as qualifying bets. New customers with STS must place a multiple bet with two selections or more to qualify for the bonus. However, the welcome bonus is transparent and easily achievable. The qualifying conditions means the offer provides a good incentive to register, deposit funds and bet.

STS Ongoing Promotions (Last Updated: October 2020)

Some bookmakers focus their promotional budget on a welcome offer but others also have an extensive range of ongoing promotions for existing customers. STS combine both types of offer but at any time there are only a few offers for current players. The site has a £50 (or currency equivalent) casino welcome bonus. This sat alongside the sportsbook welcome offer and the following dynamic promotions when the review was completed early in September 2019:

Basketball World Cup £5 Free Bet

This is a sports and event-specific dynamic promotion that has a limited life. In fact, it was only available during the basketball World Cup in August and September. Once the offer expires, there should be other sports-related bonuses which will be introduced just before the specific event. New customers could claim £5 in the form of a free bet on the tournament. This free bet complements the generic welcome bonus and new customers are eligible for both offers. The free bet is credited once new players have achieved the welcome offer free bet requirements. It is an additional £5 free bet and not an alternative to the welcome bonus.

Acca Insurance

Customers will receive a refund for the value of the bet when one selection in a multiple bet with 6 legs or more does not win. This is a common concession for all players but other bookmakers allow accas with five selections. The bet must combine six or more football markets in an accumulator. The qualifying stake is £2 to £50. Each selection in the acca must be included at odds of 1.60 or bigger. The offer is a 100% matched bet bonus because the refund equals the value of the bet. The free bet token expires after 14 days. The stake is not included in any returns from the free bet.

STS Markets & Betting Options

‘Sports’ is the second option on the main menu on the STS Home Page. The first option is In-Play which reflects the importance of live betting with this operator. The sports page displays banner links to the welcome offer and ongoing promotions for existing players.


Customers can locate a betting event by entering a word or phrase in a search box. Bettors can create a list of Favourites which eases navigation. There is a list of Top Leagues which includes the main betting events of the day. Customers can display the upcoming markets by hour. The main list contains about 50 sports which are roughly displayed by order of popularity. In addition to the regular sports, STS bettors can place wagers on Politics, TV and Entertainment and Awards. At the time of writing the three most popular sports by the number of current markets are football, tennis and ice hockey. Here is bet information about these three sports.


Football accounts for more than half of the current bets. Customers can place match and outright bets on many leagues and competitions from around the world. The offer includes the main domestic leagues in Europe and South America and the more obscure from all the continents. The most bet on leagues are the Premier League in England and the Champions League. There is a boost in football betting when there are international tournaments during the summer. The World Cup and European Championship finals take place alternatively every two years over a four-year cycle.

STS displays the three-way match result market for a typical football fixture. Customers can bet on up to 300 additional markets which are displayed under the following headings:

  • All

  • Match

  • Totals

  • Handicaps

  • Halves

  • Players

  • Minutes

The match outcome market (Home Win, Draw, Away Win) is compiled with a margin of over 6%. This is significantly above the average. Recreational bettors may not notice the variance but professionals will bet elsewhere on margins of as low as 3%. The margins on the more exotic bets are about average.


Tennis is the second most popular betting sport with STS. The dominance of football is illustrated by the relative number of markets for each sport. There are five times more football options than tennis bets. Customers can place wagers on matches and the outright winner in the ATP and WTA tours, Challenger tournaments events and International Tennis Federation (ITF) events. Tennis is rare in that there are more bets placed on in-play events than pre-match markets. The most popular tennis bets are the match result, handicaps and totals. The more exotic bets provide the potential for a significant win for a small stake. The two-way match result has a typical margin of almost 6% which is somewhat above the industry average.

Ice Hockey

Ice hockey is the third most popular betting sport with STS. Despite operating in the UK, the bookmaker does not offer a horse racing service. This is a key sport for UK-facing operators and its absence suggests STS does not have a large core of customers in Great Britain and Ireland. Customers can bet on a wide range of European domestic leagues. However, the most bet on ice hockey competition is the National Hockey League (NHL) in North America. The most popular betting markets are the match result excluding overtime, Over/Under totals and handicaps. The three-option match outcome market is complied with a margin of over 7% which is about average.

STS Mobile Betting And Sports App

STS have not developed and launched a downloadable mobile app for iOS and Android devices. However, the website can be accessed on mobile phones and tablets when the browser is optimised for mobile. Users of iOS and Android equipment can install the website on the mobile devices. The mobile version is fully functional and replicates the PC service. There are no mobile specific sign up offers or ongoing promotions. However, mobile users can claim the welcome bonus and enjoy the benefits of dynamic promotions for existing customers. The mobile release is easy to read and navigation is fast and intuitive.

STS Bookmaker Features

STS is a traditional fixed odds online bookmaker so not a spread betting firm ort betting exchange. So, the operator offers the following standard bookmaker services:


In-play is the first option on the main menu on the STS Home Page. Selecting this option takes customers to the in-play page which displays live events for about 15 sports. The most popular sports for in-play betting are football and tennis. There are up to 50 betting options during an in-play football match. STS does not provide live streaming. However, the interface shows a graphical representation of the action

Bettors can refer to live match data before placing a bet. The odds are taken down when there is a significant incident like a goal in football or break of serve in tennis.

Cash Out

STS is one of the many online bookmakers that allow customers to cash out bets during a live event. The qualifying bets can be placed in pre-match markets or earlier during the live event. The purpose of cash out betting is to guarantee a profit or limit the loss, regardless of the outcome of the fixture. The cash out offer from STS depends on the stake and odds of the original bet and the odds at the time of the cash out request. Customers can take advantage of the market when the odds move in favour of the bet. The offer can be rejected and the bet stays open.

STS Banking Options

STS offers the standard methods for transferring funds. Customers can make a deposit using popular e-Wallets, the main debit cards, prepaid cards and Bank Wire Transfer. The same options apply to taking funds from an STS betting account. Deposits are generally free and immediate. Some withdrawal methods carry a nominal charge. These transactions are subject to standard delays of 2 to 5 working days.

Opening An STS Account, Deposit And Bet

Potential new customers visit the STS Home Page and click ‘JOIN’. The registration process is one of the less detailed in the online betting industry. The sign up screens feature boxes for a unique Username and Password. There is a field for an optional promo code. Once the required fields have been populated new customers create the account. Players must confirm acceptance of the site Terms & Conditions.

New customers are prompted to make an initial deposit. The minimum transfer is 310 and there are no charges. Depositors must select the payment method and enter the amount. STS accept the payment if it is within the lower and upper deposit limits. The operator can accept higher deposits at their own discretion. When the transaction has been accepted, the account balance is updated and the new customer can bet.

The bettor navigates to the specific market and clicks the odds. The Betslip appears with the bet details. Customers can choose from an increasing number of bets as selections are added. They enter the stake and accept the odds which can change during the bet placement process. The customer places the bet which STS usually accepts and updates the account balance accordingly.

Customer Support

Customers can read a detailed FAQ section, refer to the betting rules and examine responsible gambling measures. The customer support team can be contacted by email but there is no telephone support or Live Chat. Email response times are unclear.

More On The Bookmaker

STS has been operating in its current form since 2008. The operator has a core of loyal customers but they do not have a major presence in the UK. The welcome offer is for a modest amount and the odds do not offer the best value. The bookmaker survives on brand loyalty rather than one feature or the odds.

STS Bottom Line

STS is a mainly mainland Europe-facing bookmaker. Despite having a licence to operate in the UK the firm does not compete with the traditional betting brands. There is not one feature that makes STS stand out. However, the range of betting markets for pre-match, in-play and ante-post betting is a major positive. Live Chat and live streaming would enhance the service but for now they are not available. Even so, STS is a good destination for betting on a wide range of sports.
