The 50 bonus spins will be given in five batches, each of them with 10 spins, with each batch specific for the five included slot games.

How Our Experts Evaluate & Rate STS Casino | Complete Review

Reviewing an iGaming site is not a task we take lightly. Still, we approach every platform seriously and subject it to a step-by-step procedure.

Our methodology is based on our vast experience evaluating operators’ services. The employed review method is continually modified by incorporating new tactics and criteria for assessing a platform.

Analysis methodology

We analyse different aspects of the gaming offer which influence the overall player experience. The starting point is the legality, looking into its licences and then transitioning to the user interface, especially procedures relating to registration and claiming bonuses.

We manually test these segments by assigning three testers to open accounts and determine if the process is straightforward or complex.

The cashier is the next stop, checking the available payment providers by depositing funds to test speeds and regulations. We consider playthrough requirements and bonus deals available for novice and regular players.

Playing the games is the best way to test the gameplay and uncover any glitches. We move on to the withdrawal stage once we examine the available game types. Limits on payouts and time frames are of particular interest.

STS Casino Registration Process Preview

STS Casino Look & Feel 4.5 /5

The graphic style of the site is impeccable on both mobile and desktop, and the load speeds are equally reliable. Navigating the site will be intuitive for both novice and seasoned players. From a design aspect, the layout is typical for a modern iGaming site, with a large carousel banner displaying current and any upcoming STS Casino bonus code and a comprehensive gaming menu.

Migrating between pages is streamlined with very responsive tabs and icons. Everything is neatly organised, and although the darker tone can appear to camouflage some of the options, it won’t be a problem to identify the icons.

Such interface aspects made it easy for us to navigate through the website for our STS Casino review, an effect that other gamblers will feel as well.

How to Complete the STS Casino Login Process?

  1. Go to the site’s main page.
  2. Click on the Join button
  3. You can claim a Welcome STS Casino bonus code.
  4. Provide the requested information.
  5. Once you click on Complete, the site will send you an SMS with a code to finalise the registration.

For future reference, you can also save the credentials in the browser for faster login times.

STS Casino is better than the UK average for bonuses as it provides 50 free spins on sign-up. However, just like any other UK casino, you must verify your account if you want to benefit.

How to Verify an STS Casino Account?

To fully use any STS Casino bonus code and all other features on the platform, we recommend that you quickly complete the KYC procedure. Here are the steps:

  1. Login on the platform.
  2. Click the profile icon.
  3. Select Required Documents.
  4. There are fields with upload tabs for the required documents on the new page.
  5. Submit photos of the necessary documents.
  6. The verification usually takes up to 48 hours, but it can sometimes last longer.

KYC Documents

  • Passport
  • National Identity Card
  • Driving Licence
  • Bank statement
  • Utility bill

You must upload two separate documents to prove your identity and address. Apart from photocopies, you’ll have to send additional selfies of yourself holding the documents. The best strategy is to upload all necessary documents at once.

That way, you can avoid prolonged processing, considering the documents are processed chronologically. Every photo must be high resolution, yet, not larger than 5MB. The information in the pictures must be readable.

How to Close an STS Casino Account?

For those that wish to close their accounts due to responsible gambling reasons, we’ve compiled the following steps for our STS Casino review:

  1. Open the site.
  2. Inform the customer support team of your desire to terminate the account.
  3. The customer agent will close the account.
  4. If you choose permanent closure, there is no option to reopen the previous account or to register a new tab with the operator.

STS Casino Desktop Preview

For the current STS Casino review, our experts found that a desktop app is not part of the gaming package.

You will have to rely on the native browser to access the mobile casino platform. The good news is that you’re on a top mobile casino, so any internet browser will work fine. Our testing showed that the load speeds are almost identical on Chrome, Safari, Mozilla and Opera.

Once on the platform, use the header, which is the epicentre of all crucial options to navigate the site. You can access the STS Casino bonus code section, Live Dealer, Blog, Deposit section and Account profile.

The inventory of games includes sections for new releases, slots, Megaways, table games, and casual games. However, filter options are limited apart from the general grouping of games by type, while arranging them by developers is also an option. The search bar is practical for locating a specific title.

STS Casino Mobile Preview

The responsive website is compatible with modern mobile browsers on Android, Windows, and iOS devices.

The straightforward interface makes navigation easy, with a similar theme and menu to the desktop version but in a vertical layout, which is more appropriate for gaming on a smartphone.

For some players, the experience of playing an STS Casino bonus code could be better than on PC since the performance is improved.

Further testing for our STS Casino review confirmed that this is due to the smaller screens needing fewer resources allocated for loading flashy parts.

There is no app available. Our STS Casino review will be updated in case they release one.

STS Casino Slot Games 5 /5

Going through the slots library for our STS Casino review revealed games from important developers such as Pragmatic Play, Play’n GO, Greentube, Relax Gaming and Thunderick, being the best known.

In total, you can find over 1300 thematic slots in the lobby. One drawback is the absence of demo versions. Yet, on the whole, the portfolio offers a balanced selection of slot games.

You’ll be able to search through the games by filtering them by provider. However, you won’t be able to see any info unless you open the game and search through its Settings.

Best STS Casino Slots

  • Great Rhino Megaways
  • Money Train 2
  • Fire Joker
  • Big Bass Bonanza
  • The Dog House
  • Aviator
  • Cash Patrol
  • Wild West Gold
  • Fruit Strike
  • Gunslinger Reloaded

We highly recommend checking out the best slots on this website before claiming any STS Casino bonus code since the experience can be highly improved.

Highest RTP Slots From STS Casino

  • Fruit Warp – 97%
  • Erik the Red – 96.95%
  • Poltava – 96.4%
  • Wild Toro – 96.4%
  • Ho Ho Tower – 96.4%
  • Hidden – 96.3%
  • Route 777 – 96.3%
  • Katmandu Gold – 96.2%
  • Wolf Gold – 96.01%
  • Ice Wolf – 96.1%

The developers supplying games to the operator offer RTPs of 94% to 96%. This is a typical average platform, and it’s encouraging that there is a relatively small number of games with an RTP that dips under 94%.

Playing high RTP games with an STS Casino bonus code will help in increasing the number of funds you earn.

STS Casino Live Casino 5 /5

There are over 60 games in the lobby, hosted by professional croupiers and streamed in a high-resolution video feed from a realistic studio.

Furthermore, live dealer games come from essential providers in the industry, such as Evolution Gaming and Pragmatic Play.

The nice touches are that Brits can add these games to their favourites list, the betting limits are shown, and the available seats.

The choices of payment methods are not the most numerous, yet, the approved banking methods are reputable brands frequently used by British players. In this case, all cashier options facilitate both deposits and withdrawals.

STS Casino Deposit Process

  1. The process of depositing for an STS Casino bonus code looks like this:
  2. Log in to your account.
  3. Click the Deposit button in the header.
  4. Select the preferred deposit method from the suggested brands.
  5. Enter the desired deposit amount.
  6. Confirm the transfer.
  7. The funds will appear on the account balance within minutes.

What Is the STS Casino Minimum Deposit?

The operator requires a minimum deposit of £10 to play in the lobby. For bonuses, the same rule applies: deposit £10 play with extra spins or bonus money.

The amount doesn’t change, no matter which banking option you pick.

STS Casino Withdrawal Process

If you were wondering how to withdraw funds from an STS Casino bonus code, look no further than these steps:

  1. Open the platform.
  2. Access your profile and select the cashier tab.
  3. Choose the withdrawal option.
  4. Only the payment method used for deposits is valid for payouts.
  5. Enter the withdrawal amount.
  6. Verify the transaction.

The operator requests proof of ownership of the payout banking method before greenlighting any transaction. This measure is in place to prevent an unauthorised outflow of funds, meaning withdrawals are addressed only to a registered player.

Withdrawals must be performed through the method chosen for deposits unless unable to do so. In that situation, the platform may designate a method, or the player can select a new payment option.

If several methods are used for deposits, the operator can split the cash-out amount and transfer it through the payment providers used for deposits.

STS Casino Withdrawal Time

This gambling website aims to process a cashout request within 24 hours. Seasoned gamblers will appreciate the fast casino payouts since most betting websites have a 48 hours standard.

Reasons for STS Casino Payout Problems

There are many reasons why a payout may fail, but the ones below are commonly seen:

  • Provided banking details are incorrect or incomplete
  • The operator requires additional KYC checks
  • Not respecting wagering requirements for a bonus
  • The payout amount is over the permitted limit

If you cannot identify the final reason, take your time to write a complete explanation to the email team to sort this problem out more efficiently.

STS Casino Fees

There are no fees for deposits and payouts. Still, there is an exception for a withdrawal request submitted for a deposited amount not used at least once. A 5% fee is charged to cover the provider’s cost in such a situation.

The only other fee instance is a £5 charge for a dormant account.

The platform boasts a license from the UKGC and cooperates with eCORGA to ensure fair outcomes. Responsible gaming policies are part of the operator’s strategy, offering self-exclusion schemes in conjunction with GamStop.

The parent company doesn’t have any other gaming hubs under their name.

UK Gambling Commission UK Gambling Commission

STS Casino is Legit?

Researching the legal side of things for our STS Casino review, the only license we found is:

  • UK Gambling Commission

The site’s legitimacy is verified by the licence number from the UK Gambling Commission, signalling to British players that it’s perfectly legal to play on the platform, which abides by the regulations and offers fair outcomes.

Is STS Casino Safe?

This iGaming site complies with legal requirements set by the UK Gambling Commission, protecting players’ funds through verification checks to prevent fraud.

On top of that, modern encryption methods create a security umbrella over the website. All offered games have been tested for fairness by third-party agencies. The operator is big on promoting responsible gambling.

  • eCORGA
  • SSL encryption
  • GamStop
  • GamCare
  • BeGambleAware

STS Casino customer service 4.5 /5

The customer support team takes their job seriously and immediately responds when reaching out through the live chat. Phone support is not available, but there is an email address you can use to submit a question or a complaint. Overall you can expect solid backup in an emergency.

How to Contact STS Casino?

The live chat offers real-time assistance, but only during its working hours of 10:00-22:00. The workload is allocated to a bot during off hours. However, the bot is also active during the day, preprogrammed to answer common questions.

Suppose the bot cannot resolve your issue. In that case, you will get connected to a team member who can better interpret your situation and respond politely and efficiently.

An alternative option is the email address, but be ready for a slower response time of up to a day. It’s a suitable method when you need a more extended clarification of a topic, but only if you’re not in a rush.

How We Tested Customer Support?

Players are not interested in customer support until they need help. That’s why we do our best to filter out all the faults in the service and identify pros that can enhance a gaming experience.

Our testing process focuses on the interaction with the agents, assessing their response time and how well-versed they are about the procedures and policies on the platform.

Every communication method is put under the microscope, grading the performance at each step. In this case, we can report that the platform’s customer support passed the screening process.

No phone available
Live chat:
Yes, 07:00-00:00 CET

Loyalty 1 /5

This operator is not offering a VIP programme to its members. The only thing akin to this is a Jackpot Club, which gives incentives for playing Jackpots.

Still, there are few explanations given for it.

What to look forward to at STS Casino

  • Extensive library of games: UK players can choose to play slots from more than 1300 options
  • Fast withdrawals: The platform aims to process a withdrawal request in 24 hours, faster than the 48 hours standard
  • Necessary providers: The games here are provided by essential developers such as Evolution Gaming and Pragmatic Play

STS Casino’s flaws but not dealbreakers

  • No apps: There are no downloadable apps
  • Lack of VIP: UK punters that are looking for a straightforward VIP will not find such a thing here

What STS Casino is great for

The main things that will attract players here are the banking options and the withdrawal time. To clarify, the platform aims to process withdrawals in 24 hours, half the time of the industry standard.

Furthermore, punters can deposit and withdraw via popular methods such as Pay by Mobile, Visa, PayPal, and Skrill.

Is STS Casino the best choice for you?

If you are looking for the best slot options, look no further than this 1300-slot library. The games also come to form essential providers such as Play’n Go and Microgaming.

To complement this, the site processes cashout requests in 24 hours, allowing punters to use payment methods such as Visa, Skrill, PayPal, and Pay by Mobile.
