  • Large Amount of Restricted Countries
  • No Dedicated Mobile App

Free Bets & Sign-Up Offers

All new players that create an account with STS will be able to claim their free bets offer upon completing the registration process. These are used to entice new players to create an account with a particular bookmaker and are shared among other bookmakers. There is more than one STS welcome bonus, and we are focusing on the sports sign-up offer, which allows you to claim £50 cash.

This STS bonus is available to new customers only when they make a minimum deposit of £10 after creating their account. The premise of the welcome offer sees players receive up to £50 cash. To claim this cash, you will be rewarded with £5 cash for every £100 you wager at STS.

No STS betting promo code is required to claim this offer, with punters having to follow each of the steps above. You must remember the type of bet you need to place to qualify, which is at minimum odds of 4/5 on a single accumulator that can be pre-match or in-play.

We like this welcome offer for high-roller players, who will likely receive the £50 cash bonus by making the big initial qualifying deposit and bet. However, for the more casual punter, it’s unlikely they would wager the amounts required to qualify for it. It appears the main focus of this offer is designed towards those who will go for the bigger max bonus.

Joining Instructions For STS

To be able to claim this welcome offer and begin playing on STS online, you will need to complete the registration process. The signup experience is simple, allowing you to spend less time entering personal details and plenty of betting time. To begin the process, click ‘join’ in the top right corner of the home screen, after which you will be taken to the registration page. This will require you to enter details such as your name, date of birth and email address. You will also be required to choose between claiming the STS sports bonus and the STS casino bonus. You will not be asked to enter either a STSbet promo code or a STSbet bonus code to claim these bonuses.

Enter all of your details correctly, and once your account has been verified, you will be free to browse their site as you wish. You will then be able to assess all of the sports betting options available to you and begin using your bonus funds.

Markets & Betting Options

There is a wide variety and selection of sports for you to choose from at STS. The list of betting options can be found on the left side of the screen, and you will immediately see many betting markets and sports to choose from. This will guarantee that there is always something to bet on with STS.

Regardless of whether you want to bet on popular competitions such as the Premier League or secondary sports like table tennis. The wide range of markets sees punters have the chance to bet on a host of different outcomes potentially associated with an event.

Each of the following sports is available to bet on at STS which includes Football betting, Tennis, Basketball, Volleyball, Ice Hockey, MMA, Handball, Special Bets, Snooker, Darts, Boxing, Ski-Jumping, Alpine Skiing, Cross Country Skiing, Biathlon, Formula One, Badminton, Golf, Rugby Union, Rugby League, Aussie Rules, American Football, Baseball (more on Baseball betting sites), Cycling, Futsal, Cricket, Speedway, Table Tennis, Water Polo, Chess, Hockey, NASCAR, Squash, Floorball, Sailing and WWE.

You can find more cricket betting sites here.

You may have noticed that horse racing is not listed, which is one of the bigger disappointments associated with the STS’ sportsbook. Horse racing fans will have to look elsewhere if they are looking for a new sportsbook to bet with.

Live Betting & In-Play

You can choose to participate in live betting and in-play betting when you bet with STS. It’s easy to find all the live betting choices available to customers with all the live markets presented in the middle of the home page under ‘live now’. Beneath that, you will see the complete list of live events currently available to be wagered on.

For those who have not done it before, in-play betting is the art of betting on an event once it has already begun. It has become trendy amongst online sports bettors, particularly those watching the event live. The odds presented to you will reflect what has gone on within the event when you are betting on it. In-play betting is a double-edged sword as it can give you enhanced odds on what you may have got pre-game but can also go the other way with shorter odds on specific markets.

Ongoing Promotions & Offers

Not only can you claim the new customer offer with STS, but further promotions are available to punters. These can help give you the most competitive odds and value on particular selections across their sportsbook and potentially some bonus packages. Most betting operators will have an extended promotions page, which will really give you an enhanced betting experience.

The following list of promotions is available to all of STS’ customers:

English Football Weekly Bonus – Customers can receive a weekly £10 sports bonus when they place a multiple winning bet on Premier League matches and Championship matches.

Extra 6+ – This promotion gives you insurance on your football coupons. If one leg of your 6+ fold accumulator lets you down, you will be refunded 100% of your bet. Refund amounts fall between £2-£50, and money is refunded as a bonus amount you must wager within ten days.

Champions League: £10 Football Bonus – Get a £10 football bonus if your multiple bet on Champions League fixtures loses.

VIP Promotions & Player Rewards

At the time of writing, there was no information on the STS site relating to a VIP club or loyalty program for players to enrol on. Many bookmakers and casino sites will create a loyalty program for high roller players to enrol on to be rewarded for their high wagering amounts throughout a set period. This will be disappointing news for players who enjoy programmes that often reward you with bonus packages, although it won’t have much of an effect on the casual punter.

Casino, Slots & Bingo At STS

As previously mentioned, the STS Casino is also available to punters who create an account with the bookmaker. There is the option to claim the STS Casino bonus offer if you wish to do so, which will allow you to earn up to 500 free spins once you have completed the signup process. The STS Casino features various casino games and a wide variety of slot games.

Players can separate which games they want to play by the types of games that they are, such as video slots, jackpots and megaways. There is also a variety of table games to choose from. Unfortunately, for those who may have been interested, no bingo games are available for players at the STS Casino. If it is bingo that you are looking for, you will be better off looking elsewhere.

While there may be no bingo, they have sections on their site dedicated to esports tournaments, with all of the most popular esports leagues featured and containing a whole host of markets to bet on. This will come as welcome news for esports punters, with esports betting now common practice for online betting sites to cater for. There is also a section of the site dedicated to virtual sports, giving you unique virtual sports betting odds for a selection of simulated events.

Play on Mobile & App

Unfortunately, no STS app is available to download onto your mobile device at the time of writing. This is a real disappointment, given that most significant bookmakers now offer their customers an app to download, and it will be a letdown for mobile players.

There is, however, a mobile version of the site that you can access via your device’s web browser. This has an almost identical layout to the desktop version of the site and allows you to bet on all of the same sports and markets that are included for other players. You will also be able to access the same offers and promotions when you play on the mobile version of STS.

Payment Methods & Depositing

There are several different betting payment methods that you can choose from when it comes to funding your STS account. While they may not have as many payment options for you to choose from as some other bookmakers, there is still more than enough for you to use the one you want. It also helps that STS has allowed punters to use standard payment methods that are popular online ahead of providing plenty of obscure payment options.

Each of the following payment methods is available when you come to deposit with STS at any time of day:

  • Visa
  • Mastercard
  • Neteller
  • Skrill
  • Paysafecard
  • Maestro

You can find more Skrill betting sites on our website.

Is STS Trustworthy?

STS is a trustworthy bookmaker that you can feel confident about gambling and banking online. This is thanks to the licenses they have acquired over the years, starting with the UK Gambling Commission. This license allows them to operate in the United Kingdom and lets you know that they are a reliable bookmaker since the UKGC only awards licenses to legitimate online betting sites. You should always check with them if you are unsure about a bookmaker’s trustworthiness. They gained their licenses in December 2019, which added to their licenses from the Malta Gaming Authority.

Customer Support

You should contact their customer support team if you run into any problems when using STS. Players who do so will have two choices, the first of which is their live chat service. This is available 24/7 and allows you to speak directly to a member of their customer support team instantly to discuss any issues or queries that you may have regarding your account. We would always recommend starting with the live chat service of a bookmaker, as you will tend to get the quickest resolution to your problems or questions without delay.

If it isn’t such a pressing matter and you can wait for an answer, you can use the alternative option of contacting them via email. Contact them using today to get the quickest response to your queries. There is no option to contact STS via telephone, although you can find the FAQ page for the answers to any frequently asked questions.

Language Support

English is not the only language you can have presented on the screen when you bet with STS. It should be no surprise that Polish is the alternative language available to English on STS, as it is a Polish bookmaker. Players used to be able to switch the language to German on STS, although that is now not an option for players. This is a minimal language selection compared to other bookmakers within the betting industry.

STS Summary

For such a new face in the UK gambling scene, STS has plenty going for itself. Their range of sports to bet on is outstanding, and their depth of them is good enough to rival that of any other bookmaker. The registration process is straightforward to complete, and the STS Casino also gives you extra betting opportunities if you want to take a break from sports betting.

We were, however, left slightly disappointed by the fact there is no STS app to download and the fact that there aren’t too many ongoing offers and promotions. You can expect to find these two crucial elements elsewhere and may lean one or two punters towards their competition.

Still, for those who aren’t particularly bothered about either of those factors, there is more than enough to sell you on STS. Create an account today to begin playing with the new customer offer and bet on their selection of sports.
