Best For...

This casino is relatively new as it only hit the market in 2019 and is fully licensed and regulated. This online casino started out as being the largest bookmaker in Poland but wasn’t fully satisfied with its status. It’s because of this that they started an online casino with the intention of being “the best online gambling site ever.”

STS Casino offers players a safe and secure online casino environment where the fun begins the minute you log in to your account. This online casino offers players the best variety in games ranging from regular casino slots and table games to live casino, esports, virtuals and sportsbook.

On top of that, you can cash in on the best range of bonuses and promotions across all game sections as well as scoop up loyalty rewards while playing your favourite games.

Take a read through this in-depth review of all STS Casino has to offer new and veteran players and you can decide whether or not it’s a casino worth playing at.

STS Casino Bonus

At STS Casino you will have access to the best bonus promotions and rewards. These include two different welcome bonuses for the regular casino games and the sports section.

STS Welcome Bonus

All new players at the casino can look forward to a Casino Welcome Package that includes a 100% bonus of up to €300 and 100 free spins. To claim this welcome offer all you need to do is sign up to the website with your email address and password by clicking “join” at the top of the page.  You can then claim the welcome bonus package by making a minimum deposit of €10.

The welcome bonus package will be divided over your first three deposits at the casino. On your first deposit, you will receive a 100% deposit match of up to €100, on your second deposit you will receive 100 free spins on the NetEnt Starburst slot and on the third deposit you will receive a 100% match bonus of up to €200.

All bonus funds and wins from free spins need to be wagered 35 times before any withdrawals can be made. The free spins will be released in batched of 20 from your second deposit for five days.

For UK players, the welcome bonus consists of 500 Bonus Spins. Make the first deposit of at least £50, if lady luck is not on your side and you lose that amount, STS Casino will give you 500 Bonus Spins. Offer is active for 14 days from registration.

The 500 bonus spins can be used on selected slots and there are no wagering requirements on bonus spins winnings. The Bonus Spins are valid for 7 days and each bonus spin is worth £0.10 each. Some deposit methods are restricted, full terms and conditions apply.

Sports Welcome Bonus

Sports fanatics can look forward to a warm welcome and a 100% first deposit bonus to start your sports betting journey. Once you registered your casino account you can go to the bonuses section and then the sports tab to claim the “100% first deposit bonus”.

From there all you have to do is make a deposit and the bonus amount will be added to your account automatically. Any deposits made via Paysafe, Skrill, EcoPayz, Rapid, MuchBetter or Neteller will be excluded from qualifying bets. You will have 30 days to wager the bonus once you’ve received it.

At STS Casino not a day will pass where you will be without additional entertainment and bonus boosters. As a frequent player, you can also look forward to loyalty rewards which include free bets and bonus bets. No player will go unrewarded and STS Casino.

STS Casino Bonus Code

While some online casinos require you to insert a bonus code before you can claim your welcome bonuses STS Casino doesn’t. The casino welcome package can be claimed by making a deposit and the sports welcome bonus can be claimed by clicking on the promotion itself and then making a deposit.

If the casino requires a bonus code for any bonuses in future they will clearly state it in their terms and conditions and provide you with the bonus code needed. In such a case you will need to insert the provided bonuses code at the cashier when making your required deposit.
