Bonuses on your first 3 deposits? Yes, please! Read on below for the full low-down on the welcome package. We can tell you upfront, however; It’s solid.

STS Casino is a fully-fledged gaming platform, offering casino and sports betting. They have operated in the EU for years, and we are excited to see them branch into the UK. It is easy to navigate, and looks, quite frankly great.


At the point of writing this review, STS Casino just got their UK license. Be a little patient with them. Offers are still in Euros, though we hope this has already been fixed by the time you are reading this.

Grab up to £300 + 100 spins

When you make your very first deposit at STS Casino, you will be able to double your money. And just so you’re warned, that’s just the start.

Your welcome offer is split in 3.

First, you will be able to grab 100% up to £100. Then, on your second deposit, you will be able to claim 100 bonus spins. These spins will be given out in sets of 20 over the coming 5 days. Finally, on your third deposit, you can collect 100% all the way up to £200.

The minimum deposit required for each offer is £10.

There is also a really cool thing we didn’t mention your bonus spins. They are not locked to one specific slot. That means you can choose whichever slot you want, and spin away. Please note, a few high RTP slots are excluded. The full list will be found in the T&Cs. This list is, however, surprisingly short.

To convert the bonus into real money simply wager the bonus amount (and bonus spins winnings) 35 times. You have 30 days to do this. If you have not completed the wagering/turnover requirement at that point, STS Casino reserves the right to remove your entire bonus amount.

Keep an eye on the promotions page

If you want further offers it is good to check the “Promotions” page. Happy surprises should be coming up. This is also where you will find the offers for their sports betting section.

Constant tournaments

One major reason to join in the fun, are the tournaments. Just play the minimum wager allowed, and you are in. Quite a shocker, and quite unusual. Most casinos set a reasonable bet requirement. This makes the STS tournaments among the most accessible.

They are all displayed on their own subsection and have all the info you need (including the timer). Give it a look-over, you might just like it.

Play well over 1000 games

We can’t lie, we are actually impressed here! As soon as you enter the casino section you will see the latest and greatest games, and what is above them?! Well, a colossal list of absolutely fantastic game providers (and some lesser ones too). For a gaming platform mainly renowned for sports betting, this is such a good surprise.

You can really tell they have given this collection thought. The only real downside is the lack of major jackpots. Many of the mid-tier ones, like Major Millions, Divine Fortune and King Cashalot is here, but the big players are not.

Sports betting and e-sports

Want more than the standard casino experience? Then STS may just jump up a few notches in your books. They have a top-notch betting site, including live games, and even offer odds on e-sports. Give the selection a spin, and we think you’ll like what you see.

Quick and easy deposits and withdrawals

You will be able to use credit/debit cards, e-wallets and third-party solutions for your deposits and withdrawals. Prepaid cards (Paysafecard) can be used for deposits only. Not too shabby. You will however not be able to make a direct bank transfer. See the full list of available methods below:

UK and MGA license in place

STS Casino opened its doors in 2014 and operates from St. Julians in Malta (a popular casino district). Until 2019 they operated with their MGA license only, but they are now also the proud holder of a UKGC license. We hope and assume the localization for UK players will improve in the future.

Get in touch with support 24/7

Your STS support agents are on-call around the clock. This is a major advantage over other new UK casinos. Having operated in Malta for a few years already has without a doubt given them the ability to compete.
