STS Casino Game Variety

There is plenty of game variety at STS Casino, with customers able to choose from different sections of the website. There are popular slots and new online slots available, while slots fans can also enjoy video slots, megaways and jackpots. There is also the chance to enjoy table games and even opt to go down the live casino route.

There are 949 different video slots available at the time of writing, so that means plenty of choice available. Should you want Viking, Norse, Roman, Egyptian or Mythical themes, then you will find all of these options at STS Casino. Megaways and Jackpots fall into a similar category in terms of more ways to win and there are also strong options here.

There are around 50 different table games that can be enjoyed and you can also choose from around 25 drops and wins options, along with the chance to choose games according to software provider.

STS Live Casino

There are 21 direct roulette options and that includes heading to the Evolution Roulette Lobby, while the Blackjack Lobby can also be tapped into.

Therefore, there is no problem logging into your STS casino account and you have the option to type in a username/password or alternatively use Touch ID in order to log in and access the latest games.

The desktop navigation is really nicely structured and it’s good to see an online casino that has put some real thought into the layout so that customers aren’t endlessly scrolling through a panel of games and working out which ones to play. The gameplay is immersive whether you go down the desktop or mobile route and it’s an experience we would recommend.

STS Casino Payout Rates

Every casino game at STS has a different payout rate. Customers should generally expect the popular video slot games to have a Return to Player percentage of 95%, while the higher percentages are reserved for blackjack and roulette games which can be found among the table selection.

With regard to the Megaways and jackpot selections, expect the RTP to be on the lower side and it’s customary to find a jackpot slot game around 92%, on the basis that there’s the chance to play for bigger amounts.

Progressive Jackpots

At the time of writing, there are 26 casino jackpot games available at the STS Casino. Many of these are linked to Microgaming’s Mega Moolah and this includes the flagship game itself, although there’s also the option to spin the reels and play derivatives of this game. Immortal Romance and Juicy Joker are linked to this world-famous jackpot slot, while the same applies to Fortunium Gold and Atlantean Treasures.

Aside from these games, there is the chance to play the Book of Artem Wow Pot, while there are also different varieties of Microgaming Wow Pot games including Sherlock and Moriarty, Queen of Alexandria and Wheel of Wishes. You can also find the chance to play Drop N Win and Cluster N Stack games.

Our Verdict

STS Casino is a first-class casino that offers something for everyone. They have partnered with some of the biggest software providers in the business including Microgaming, NetEnt and Pragmatic Play. We like the way that their selections of slots are categorised in a way that helps customers to narrow down their search.

You can also play a wide selection of live casino games and there is the option to rack up a deposit bonus along with other promotions. We think the new customer bonus is really generous and the fact that we’re talking about a UK-licensed operator is another big plus.


The minimum withdrawal amount at STS Casino is £10.

Yes, there are hundreds of slot games available from a huge range of software providers. You can also play lots of live casino and table games.
