STS Review

STS are new to the UK betting market, but having already established themselves in other European territories, Poland’s largest bookmaker continues its international expansion by bringing a top-class sportsbook and casino product to the table.

Choose STS for their

  • Wide range of betting markets for football and winter sports
  • Array of promotions and loyalty club offers
  • Easy-to-navigate platform with excellent search tool

The STS betting site delivers the goods in a number of key areas, one of which being its football section. There are hundreds of available bets for each major fixture, with Premier League games in particular containing a breadth of markets.

Football is also the subject of some of the STS betting promotions, and the same can be said for winter sports, which is unusual for bookies in the UK but a nice unique touch for punters who have an interest in ice hockey or skiing.

Around major tournaments, STS will run special betting offers such as a bonus bet if your qualifying bet loses. There is also an ongoing Acca Insurance promo for football wagers with six or more selections.

Crucially, the STS site looks and feels great to use. The search tool can be found at the top corner of the sports section on both the desktop site and on mobile, and suggestions appear as you begin entering your search query.

The layout of the site makes life very easy for the punter.

The ‘Top Leagues’ highlighted at the top of the page give a good indication as to the most highly-prioritised sports, and it is no surprise to see football, tennis, basketball and ice hockey feature, as well as ski jumping and handball - two big pastimes in Poland.

While the variety of events and markets on STS should be applauded, sadly horse racing and greyhounds are not available. We would love to see this added in the near future.

  • Limited customer support

One key area in which STS could improve is in the customer service department. While the staff are perfectly helpful and professional, there is currently no option to contact them via telephone, and live chat is available but customers can be faced with long waiting times.

Response time to emails is fast, but it can still be frustrating not having issues resolved instantly.

About STS

STS has been in operation since 1997 and is registered in Malta. It is one of the biggest bookmakers in Poland, and in 2019 they secured a licence for the UK.

The UK site offers over 30,000 betting events each month across 50 categories, and live games are individually traded by over 300 traders.

STS is the official sponsor of the Polish national football team, and the company is partnered with a number of other leading sports teams.

STS Betting & Products

The sports betting section of STS features a strong collection of markets, both pre-match and in-play. In-keeping with the brand’s Polish presence, there is a particularly extensive selection of available bets for sports that are popular in Poland such as football, tennis, basketball, handball, plus ice hockey and other winter sports.

British bettors may be used to seeing the likes of cricket, darts, snooker and rugby featuring more heavily, and these sports can still be found by performing a search or using the sidebar.

STS search tool

Easily find the markets you are looking for by using the search tool.

Unfortunately, the bookmaker does not offer odds on horse racing or greyhounds in the UK. This is understandable given that STS has only just entered the British market, but it would be nice to see this addressed in the future.

STS Live Odds

In-play betting has its own tab on STS, which comes before the regular sports betting page. This highlights the importance of live betting with the bookie, and many sports are offered.

Football, tennis and basketball are the most prominent given their popularity and the number of games taking place around the world at any given time. There is a terrific mix of available bets during events, such as individual points in tennis, and total points per team in a quarter of a basketball game.

Other niche events can also be wagered on in-play, plus eSports, which has the best live streaming catalogue on STS.

STS Live Streaming

When browsing through the in-play events, a small camera icon appears next to the games that can be streamed.

Live streaming is very limited outside of eSports, but the stats and graphics are an excellent alternative. Users can create their own multi-view in which they track detailed live stats and odds for multiple events at once.

STS Live Betting multiview

The STS in-play betting section looks great and is easy to use.

STS Cash out

As is now standard across all UK bookmakers, STS offer cash out on bets placed on events either in-play or pre-match.

Full cash out and partial cash out is available.

Bettors can choose to settle a bet early for a smaller return than they would get if they allowed it to run.

STS eSports

eSports has a dedicated page on STS, where a calendar of upcoming events can be seen, and sorted by game if desired.

Bets can be placed on Call of Duty, CS:GO, DOTA 2, League of Legends, Overwatch, Starcraft, and Rainbow Six. The number of markets available depends on the event, but some have over 60 different bets listed.

STS Virtuals

Players can bet on virtual football, virtual tennis, virtual basketball, virtual horses and dog racing.

Virtual games are continuous throughout the day, taking place every few minutes, with virtual football having the most markets.

STS Virtuals

Horse racing bettors can get their fix through STS virtuals.

STS Mobile

Punters can bet with STS on mobile using their web browser on a smartphone. There is no STS app, but the functionality of the mobile site is excellent and makes the betting experience just as straightforward and pleasurable as the desktop version.

The mobile site is split into three main sections: live, pre-match, and casino. For live betting on mobile, users can select their chosen sport by clicking on an icon, and then scroll through the events currently taking place.

It is best to use the search tool if you know exactly the event you want to bet on.

Otherwise, it can take longer to find games on mobile because less is visible in comparison to desktop.

STS Android

Users have access to their STS account through Android devices, and can place bets live or pre-match without downloading an app. The registration process can be done there, too.

STS iPhone

The STS site works brilliantly on an iPhone, and while there is no app, you can simply add a shortcut to the homescreen, which will essentially look and act like an app when you go to use it.

STS Premier League betting

Access the STS sportsbook via iPhone or Android.

STS Casino

The range of games available with STS Casino is top-notch, largely thanks to the array of software providers such as Red Tiger, Elk Studios, Microgaming, Thunderkick, Yggdrasil, Netent and more.

A large selection of slot games can be played, as well as video poker, jackpots, and table games like roulette, blackjack, and baccarat.

STS Live Casino

For players looking for a live casino experience, this is offered in abundance on the STS site.

Live roulette, Deal or no Deal, Monopoly, blackjack, and three-card poker are just a few of the many live games available.
