STS Review

STS is an online bookmaker operated by Vivaro Limited and registered in Malta. STS offers a wide range of sports and esports betting services to players.


Players can bet on over 50 sports and esports titles, making STS an option for all types of users. Its offerings range from soccer, MMA, esports, the NHL, and even water polo.


STS offers a rather handsome bonus for the new players. If you play your cards right, then you can get $150 of free betting money. And you can get this money over the course of your first three deposits. The first deposit bonus is a 100% match up to $25; the second deposit bonus is a 25% match up to $50, and the third deposit bonus is a 50% match up to $75. If you collect all the deposit bonuses, then you will be rewarded with $150. 


However, be mindful of the fact that you will have to reach the wagering requirement to release the bonus in 10 days or less, otherwise, the bonus becomes void. For more information about the bonus offer at STS, be sure to read the bonus section further down in this review.


One of the strongest suits of STS is the incredibly low betting margin. Currently, it sits at about 4.8% for regular sports, and when you compare this number with the industry average at 7%, you come to know just how good and favorable is the betting margin at STS. The esports betting margin tends to sit a bit higher at STS, but this is nothing out of the ordinary, as it’s usually the case that e-sports have higher betting margins than regular sports on most online sports bookies’ platforms.


The general market coverage is excellent. It’s one of the very best that we’ve come to see on online sports betting platforms. There are many different sports that are available to bet on, with many different events from all across the world. In this sense, STS offers a little something for everyone. For the sake of reference, you can bet on basketball, football, MMA, boxing, golf, ice hockey, and many other sports. There are also esports, as these have gotten highly popular as of late. Call of Duty, Overwatch, Counter-Strike: Global Offensive, Rocket League, Rainbow Six, and many others are available at STS.


To round things off, there is also an unconventional list of events you can bet on, including political events and even TV shows and movies. This, combined with the incredibly low betting margin that you can seldom find in other online sports bookies is more than enough for us to recommend STS to anyone with a remote interest in online sports and esports betting.


Since STS is licensed by the Malta Gaming Authority, it’s reasonable to expect that responsible gambling will be encouraged and enforced properly on the platform. Unlike the Curacao Gaming Authority, for example, the Malta Gaming Authority imposes a much stricter ruleset to all the casinos that it licenses, including STS. So, here you can find many different tools that are geared towards helping players that experience problem gambling patterns in their behavior. 


You can easily set up limits for your deposits and wagers, as well as write your own username in the self-exclusion and cool-down lists so that you will be barred from logging into your STS account. So, overall, responsible gaming is properly encouraged and enforced at STS with the availability of different tools that the players can easily use during their stay on the platform.


Deposits and withdrawals are very easy at STS. But one of the most important things about the bookie that we have to mention is the fact that you won’t even need to provide verification documents before you reach the $2,000 withdrawal mark. The vast majority of online sports bookies ask the players to provide persona identification documents before they can make their first withdrawal and, in many cases, even before they can make their first deposit. STS is a lot more liberal in this regard and again, you will need to reach $2,000 in withdrawals before STS asks you to provide ID documents and verify your account. And you can learn more about the exact documents that you may have to provide to STS to verify your identity further down in this review.


The number of STS payment options isn’t big, however, the most popular payment options are readily available to use. You can use Visa, Zimpler, Neteller, Ecopayz, MasterCard, and a few other payment methods. The deposits are, in most cases, instant. The withdrawals are speedy, but you may need to wait a few days for the transaction to be completed depending on the type of the withdrawal method that you will choose to complete the transaction.


There are two main ways in which you can contact customer support at STS. These are email and live chat. Both options are about equal in providing you with almost immediate access to customer service. If you’re in a hurry, then we suggest that you use the live chat option as the generally faster one. But if you have more time and you wish to compose your thoughts before asking a more long-winded question, then it may be better to send an email and to give the customer service team to form a proper reply that will completely answer all your questions. 


Still, the lack of phone support may be daunting to some, as most online sports bookie operators feature phone support options. But the email and live chat contact forms will get the job done in most cases.


And as for the live features, though there aren’t all too many of them, the most important ones are available. These are the live streaming feature and the early cash-out feature, which many players tend to use over the course of their online sports betting experience. Still, there is some room for improvement here, and STS would do well to introduce the bet builder and a few other features that are both useful and popular.


STS is an excellent online gambling sports bookie and it does many things great, while it does some other things just right. We weren’t able to find any major flaws in how this operator does business, so chances are that you will have a fantastic time wagering bets on some of the many available sports and esports at STS.

Sign-up on STS is simple and quite a standard process, a 3-step registration form that is similar to many other bookies. One simply has to register an account and then are free to deposit and play. In order to withdraw money though, the KYC has to be completed, which means that the documents have to sent over to STS.

Account Verification

Account Verification is not required for initial registration and deposits, but is mandatory in order to withdraw any funds. STS verifies accounts fairly quickly, with an upper limit on 48 hours. A valid ID and proof of address are mandatory for account verification, and STS may request proof of any payment methods upon withdrawal.

Customer Service

8 / 10

Although no phone support, STS offers 24/7 Live Chat and email support, which is good news. Customer service at STS is just adequate, as the agents give proper answers to the simpler questions that players ask, though it takes more time for the STS customer service staff to answer a bit more complex questions. Regardless you can use any of the available customer support contact options to your benefit and you will likely be pleasantly surprised by the speed and efficacy of the customer service team at STS.
