Expert's review Melanie Hart

Casino tested

If you want a casino that can cater to all your needs, then you might have found it. STS has all the slots you can dream of, a huge range of Live Casino games and if that wasn’t enough, you will also find a fully-fledged sportsbook.

With Peter Schmeichel as its mascot, it is of little wonder this casino immediately reserved a special place in my heart. The casino also gives you a chance to practice all their slot catalogue which is always a plus.

I did enjoy my experience at STS however, it did turn a little sour after the misunderstanding with the bonus copy. I do expect a casino of this size to be a lot clearer with their terms and conditions. But with friendly customer care agents and effortless money transactions, this is a solid casino.

Overall rating:


Make a first deposit and STS will give you a nice welcome bonus. They will match your deposit so you can play with more.

This is one of the most intriguing welcome bonuses I’ve ever laid my eyes on. First of all, it is only available with a minimum deposit of £50. Then, all of that £50 needs to be lost on slots. Which slot games you choose is completely up to you.

The terms and conditions aren’t very clear about this. In the Ts&Cs it is only mentioned that you need to lose £50, not that you need to lose *all* the £50. This is quite misleading in my opinion and they should make it clear the balance needs to go down to £0.

If £50 is lost from the initial deposit amount then the player will receive 500 wager-free spins. Yes, you’ve read that right. The spins don’t have any wagering requirements. The catch - if you can call it that - is that the 500 spins are only available on a handful of NetEnt slots which include Starburst and Aloha! Cluster Pays.

I deposited the £50 and started playing my favourite game of all time: Fat Rabbit. You have no idea how excited I was at the thought of guilt-free spins. After all, if I did end up losing there would be 500 spins waiting for me. I went through half my money and the rabbit was nowhere to be seen. I just couldn’t get myself to continue spinning so I changed game and settled for Wolf Gold. Here it was completely different and I managed two good wins which stabilised my funds.

To be honest, I didn’t go all the way and lose the £50 to gain the 500 spins as I still had to check out the live casino and sportsbook available. Having said that, as a consolation prize this would be a good one, but to me, it doesn’t really feel like a welcome bonus.

To be fair there are other bonuses available - for example, if you want to bet just on the sportsbook. I also noticed a good deal of promotions available when exploring the site. But this particular bonus left me a bit disappointed, possible due to the vagueness of the terms.

The amount of games available at STS Casino is staggering. I literally had stars in my eyes trying to find a game to settle on. All the major providers are here providing more than 1500 quality slot games.

If Live Casino is more your thing then you can choose whatever tickles your fancy with both Evolution and Pragmatic Play available.

Oh, but it doesn’t end there. At STS you will also find a sportsbook covering all sports events, e-sports and more.

When it comes to casino games there is a chance to demo games before you spend your cash. And when you’re in a slot game you will notice a tag on the top right corner of the game letting you know if you are in demo or real mode.

My experience with Live Casino also went by without a hitch and I spent a few good rounds happily playing Lightning Roulette and Deal or No Deal.

As for Sportsbook, I do like the layout however I was disappointed that the cashout was immediately reduced even though the game hadn’t yet started. At some competitors, you are able to cashout your initial bet provided the match hadn’t yet started.

If the desktop experience was flawless then the mobile version is simply impeccable. It takes some great UX designers to be able to fit so much into so little space without it feeling cramped and busy.

I was presented with a sleek look (yes I’m mostly talking about Schmeichel here) and fast navigation. I accessed the site via a Chrome browser on an iOS device and continued using the mobile version for most of the time as it offers a better experience.

I contacted customer support to make sure I understood the terms and conditions of the welcome bonus. Turns out, thanks to the vagueness of the offer, I did get it all wrong. A player needs to reduce their balance to £0 in order to take advantage of the casino bonus.

The person I spoke to was knowledgeable and professional however it seemed like English wasn’t their first language.

STS aims to make this process as seamless and effortless as possible to their customers by using state-of-the-art electronic age verification tools; however, in some situations, they need to complete these checks by requesting certain documents directly from the customer.

To verify the account initially, 2 documents should be attached:

  • A photo or scan of your ID (an ID card, Driver’s License, a Passport or any other government-issued ID card).

Make sure the photo/scan is not cropped (all 4 corners visible) and the document is still valid,

  • A photo or scan of your proof of address (this can by any official document, such as a utility bill, your tax return, any official letter you received - e.g. from NHS).

Please make sure, the document is not cropped (all 4 corners visible) and that the document is issued in the last 3 months.

Due to security reasons, any documents should always be uploaded to the player account: My Profile -> Documents.

However please be informed that in accordance to their t&c, STS might request you to provide further documents proving your identity and ownership of used payment methods at any later stage in line with their security standards.

This had to be the smoothest of all account creations. First off you are greeted by a smiling Peter Schmicheal - now that’s a welcome. Once you click to register the first step will ask for your email and a chosen password. The second step will ask for the usual personal details. Finally, in the last step, you can set your deposit limits and choose marketing communications preferences.

As soon as I completed these steps I received an email letting me know I passed the age verification check. Within the email, it also hinted it might be a good idea to upload any documents to verify identity. I headed to the website and under my account, I clicked on the ‘documents’ tab. Here I used their uploaded to send in a copy of my passport and a utility bill. The document uploader is, as the rest of the website, easy to use and the documents uploaded are clearly visible.

After 24 hours I received a message that my passport was rejected because it was a PDF. At STS scans aren’t accepted and they only accept JPGs or PNGs. I uploaded a JPG of my passport and another 24 hours later my account was verified.

I received an email letting me know the document was rejected but I didn’t hear anything when it was approved. It would be quite handy to have an email sent out to let the player know they are now verified.

The customers at STS have a great selection of different deposit and withdrawal methods available.

The minimum amount you can deposit and withdraw is £10.

There is a wide variety of payment options on offer here including PayPal and Bank Transfer. I deposited £50 using a Visa Debit Card. The process was quick and straightforward, with no deposit charges.

Withdrawals are as efficient as deposits. I withdrew my money on Christmas Eve, on Christmas I received an email letting me know it was processed and 3 days later the money was in my account. Very efficient considering this was across the holidays.
