Here is a list of casinos that do accept players from Japan

STS UK is a relatively new online casino, but they’ve been in the gambling business since 2008. Owned and operated by STS Limited, the company has hundreds of betting shops across Polish territory. They’re also well-known as an online bookmaker. Having acquired a UKGC license in late 2019, STS decided to expand and launch an offensive on the UK casino market.

We’re here to investigate if this casino has what it takes to provide you with an adequate gaming experience. Looking at the surface, we noticed several positives. Nonetheless, we’ll reserve our judgement until we’ve taken a deep dive into every aspect of their service.

Our detailed STS casino review will let you in on all the details; starting from the bonuses and payment methods to customer support and gaming selection.

18+. New customers only. Promotion valid from 23.04.20. Min. £50 first deposit required. Bonus spins added after min. £50 loss on casino slots. Offer active for 14 days from registration. 500 bonus spins on qualifying slots. No wagering on bonus spins winnings. Bonus Spins valid for 7 days. Bonus spins worth £0.10 each. Deposit method restrictions. Full T&Cs apply. begambleaware.org.

STS Casino’s welcome bonus is a bit unusual. It won’t be credited to your account immediately after you deposit. Instead, you will have to stake a total of £50 or more before you receive your bonus. On top of that, you get the bonus spins once you LOSE £50.

However, it does have its pros. Because the bonus spins carry no wagering requirement, the bonus terms structure is quite simple.

Bonus Terms and Conditions

  • Minimum Deposit/Wager: £50
  • Wagering Requirements: 0 X Bonus Amount
  • Bonus Valid: 7 Days
  • Deposits w/ Neteller, Skrill, MuchBetter and ecoPayz not valid for bonus
  • No Max Bet Restrictions
  • Available games: Starburst, Scudamore's Super Stakes, Finn and the Swirly Spin, Twin Spin Deluxe, and Aloha! Cluster Pays.

Our Thoughts

Lose to release bonuses are not popular, in our opinion. However, 500 bonus spins, IF you lose, is a good enough deal for us. The minimum qualifying deposit is up from £30 to £50, which is almost double! Many players will be deterred from this "high" entry level. Nevertheless, aside from that, we can't really complain, but, instead, we can recommend. It is sort of a safety net. Take it as a risk-free sports bet.

Other Bonuses and Promotions

Beyond the sign-up offer, STS casino treats its regular players with the occasional promotion. You may run into slot prize-drops, deposit bonuses or bonus spins offers. Though, this promotional lineup is prone to change.

We advise you stay up to date with their website for the latest deals, or sign up to their newsletter to get notified immediately.

Is STS a Trustworthy Casino?

When it comes to new operators such as STS Casino, the question of trust is often the biggest one. Fortunately, STS Limited and their owners (Vivaro Limited) already have an excellent reputation in the gambling sphere. They operate a number of respected betting venues, both offline and online.

This gives us some reassurance, but let’s have a good look at what they’ve done to ensure the safety of UK casino customers.

Licensing – UKGC and MGA Approved

The casino has a remote gambling license issued by the UK Gambling Commission (Ref. No. 54498). This should play a key role in maintaining your trust with the site. As a UKGC licensee, STS is bound to dozens of regulations that go towards ensuring player safety.

One of these conditions is that they must keep player funds separate from their own banking accounts. As such, you should have no worries in case of big wins. If you deem it necessary, you can also file a complaint with STS through the gambling commission. Should the casino fail to respect these regulations, they risk heavy punishment or license removal.

What’s more, STS has Type 1 through Type 4 licenses issued by the Malta Gaming Authority. This doesn’t directly affect UK players, but a Maltese license is always a great indicator of trust.

Player Security & Fair Play

The casino lets players take extensive control over their gambling sessions. This includes a number of player-controlled mechanisms such as: Self-ExclusionTime Out, Reality Check, Betting Limits, Deposit Limits.

Most of these features are common among UK sites, except for the betting limits. This is a nice extra feature that we’d like to see more of, and it’s big plus for STS casino in our eyes. You can set your betting limit on a daily, weekly and monthly basis.

The casino’s Responsible Gambling section has useful links to BeGambleAware, GamCare and several other organizations where players can seek help.

In terms of RNG verification, the casino has a link to eCogra on their website. Howeverthe link leads to eCogra’s complaint system. You can file a complaint with the organization if you are unsatisfied with the casino’s treatment. Yet, we could not find any certificates and payout reports related to STS.

Last but not least, STS casino safeguards all sensitive player data through 256-bit SSL encryption supplied by CloudFlare. This means complete security as far as your banking information and personal details are concerned.

STS Payments – Great E-Wallet Variety

STS casino goes above & beyond expectations when it comes to payment method variety. Unfortunately, the UK-favored PayPal is not available.

However, the casino compensates through e-wallets such as Skrill, Skrill 1-Tap, Skrill Rapid TransferNeteller, ecoPayz and MuchBetter.

Players can also take advantage of the standard debit cards such as VISA and MasterCard. Fast Bank Transfer is also an option, for both deposits and withdrawals alike.

Payment Limits, Fees and Withdrawal Times

The casino has perfect uniformity in terms of deposit/withdrawal limits. Regardless of which method you are using, the minimum deposit and withdrawal amount is £10, whereas the maximum is £10,000.

We like the high withdrawal limits, which high-rollers will be happy to know. The casino doesn’t charge fees to players, regardless of payment method.

Keep in mind that withdrawals require mandatory ID verification. You can complete this procedure by sending relevant documents (personal ID/passport, driver’s license, proof of address) to the casino’s support team.

What’s more, STS employs an industry-standard closed-loop policy. Meaning, withdrawals will have priority to be sent to your initial deposit method. Fast Bank Transfer will be used as an alternative whenever this is not possible.

Withdrawal Times

Withdrawal Method Withdrawal Timeframe
Debit Cards 2 – 5 Working Days
Neteller 1 – 4 Working Days
Skrill 1 – 4 Working Days
ecoPayz 1 – 4 Working Days
MuchBetter 1 – 4 Working Days
Fast Bank Transfer 3 – 7 Working Days

The withdrawal times are fairly standard here. E-wallet payouts are instant. However, the casino’s processing period can take up to 3 business days. In reality, this is the upper end of the processing period. We anticipate that most of your e-wallet payouts will be completely processed within 48 hours.

STS Casino Games and Software

STS Casino certainly knows their audience. They’ve partnered with just about every big name on the market. However, we should mention that UK favorites such as Barcrest and Playtech are not on the menu.

On the flipside, you have games by NetEntPlay ‘N GoMicrogamingYggdrasil, Pragmatic Play, Red Tiger, Elk, Thunderkick, Wazdan and Push Gaming.

We like that STS doesn’t try to keep their gaming selection a secret. You can easily see the exact number of games from each provider. Some competitors have even more diverse gaming libraries, but as far as quality goes, this casino gets the job done.

Overall, you’ll have 1100+ quality titles to choose from. The site also has a special RTP section where you can see the Return to Player percentage for each title.

Video Slots

Out of the 1100+ games we mentioned, more than half belong to Microgaming and NetEnt. This means hundreds of well-paying video slots at your disposal. Boasting top-of-the-line graphics, varying themes and bonus features, STS casino slot machines offer nearly endless entertainment.

Most of these providers’ classics are on offer. Gonzo’s QuestStarburstTwin SpinImmortal Romance, Thunderstruck I and II – these titles should be familiar to any experienced player. In terms of newer video slots, Serengeti Riches and Tiki Mania are a few notable examples on offer.

Out of Play ‘N Go’s portfolio, we can recommend their greatest hit; Book of Dead. Rise of Merlin and Rise of Olympus are also great shouts. Thunderkick hits such as Birds on a Wire and Esqueleto Explosivo are worth a look as well.

The casino also hosts a handful of Megaways slots, which are becoming increasingly popular as of late. Piggy Riches, Mystery Reels and Golden Leprechaun stand out as player-favorites, but we advise you explore the rest as well.

Jackpot players aren’t forgotten either. STS is well-equipped with over 15 progressive slots on offer. Mega Moolah towers above the rest as arguably the best jackpot slot on the market. You can also have your pick out of Rainbow Jackpots, Divine Fortune and Major Millions, to name a few.

Table and Card Games

Many online casinos have a tendency to neglect their table game selection, but STS positively surprised us here. The site has over 80+ regular table games, including all the usual classics available in dozens of variants.

Golden Chip RouletteVegas Strip BlackjackEuropean Blackjack, Casino Hold’em Poker, Double Exposure, Pontoon – these are but a few examples you can choose from. We also like the inclusion of Craps through a Vegas Craps variant. This popular land casino game is rarely available online, which is why we appreciate it at STS.

Fans of video poker will be spoiled for choice – another plus for STS. There are over 20 video poker titles on display, and all the classics are included. All American, Deuces Wild, Aces & Eights, Jacks or Better, Bonus Poker, and many others await.

Other Games

The casino has close to 20 “Casual Games”, where players can indulge in titles such as Mini Baccarat, Legacy of Egypt, Big Win Cat and Sweet Alchemy. Many of these games fall under the scratch card category, but some of them are completely unique in terms of gameplay mechanics.

A number of Virtual Sports can be found on the website as well. These simulated matches are a bit of a niche in the online gaming world, but some players like placing the occasional wager, especially during the off-season.

STS also offers “Betgames”, an interesting casino section where players can bet on the outcome of various games of luck. Such as, Lucky 5, 6 and 7, Dice Duel, War of Bets and Speedy 7.

Sports fans can also indulge in the fully fledged STSbet UK sportsbook with shared account funds.

Mobile – Well Optimized for Android and iOS

Mobile players will have no issues with enjoying STS casino on the go. The site is fully optimized to work across iOS and Android smartphones and tablets.

It doesn’t just work, but it works great. In terms of visual clarity, functionality and performance, this mobile casino ticks all the right boxes.

As far as the gaming library is concerned, players can expect the exact same experience found on the desktop site. The usual basic filters and hundreds of games await. The games themselves perform well, but that is more up to the providers than the casino.

The rest of the mobile casino lets players access a wide range of handy features. Whether you’re looking to claim a promotion, enter a bonus code or the live chat button – It’s all just a tap away.

For the time being, players can access the casino through their web browser. A native app for iOS/Android is not available for smartphone and tablet users. Alternatively, you can place a shortcut to STS’ website on your home screen for convenient access.

Live Casino

The casino has done well to include a worthy live dealer table selection. They have partnered with market leaders Evolution Gaming, as well as Pragmatic Play and BetConstruct.

When it comes to Evolution’s live games, every seasoned player will know to expect nothing but quality and variety. This means dozens of tables supplemented by engaging presenters and high-quality streams. A number of live dealer variants are on offer, catering to the tastes of regular and VIP (high-limits) players alike.

Out of Evolution’s portfolio, our personal recommendations are First Person Blackjack, Free Bet Blackjack, Two Hand Casino Hold’emDream Catcher and Lightning Dice. All of these games bring something unique to the table, but plenty of other titles are on offer as well.

Pragmatic Play and BetConstruct are not common faces in UK live casinos, but we can always appreciate additional variety. Pragmatic offers unique tables of Blackjack, Roulette and Speed Roulette. Whereas, BetConstruct boasts live Baccarat and Poker in addition to the regulars.

Every table game player knows there’s nothing quite like a live casino, and STS will be able to scratch that live gaming itch for endless playing hours.

User Experience: Top-Notch Web Design

STS Casino’s user experience is top-notch! Several aspects of their website really impressed us, but there are still areas which could use some improvements. Overall, though, we can immediately say you’ll be able to enjoy hassle-free play sessions.

The design itself is sleek, modern and flat-out gorgeous. We like that the casino puts responsible gambling first. Head over to your profile, and you’ll see that Self-Exclusion, Time-Out, Reality Check and Betting Limits will be the most prominent settings.

The account menu is quite comprehensive, yet clear and understandable. Head over to your wallet, and you can monitor all deposits and withdrawals, including pending payouts. What’s more, the casino lets you view your full betting history, including net deposit value! That’s not something we can say for every UK casino.

The rest of the website is equally impressive. Whatever you need is one click away; including a handy live chat button to your bottom left. The gaming selection is clearly organized using several game categories to ease your browsing.

You can also use the search function, or sort by provider, though only one provider is listed. This is where we found the casino’s only UI flaw actually, which is the lack of advanced filters. With 1000+ games on offer, we would’ve appreciated gaming filters by themes, RTP, volatility, features or similar.

VIP & Loyalty Scheme

Currently, there doesn't seem to be an STS VIP program in place. Some online casinos tend to hide the details relating to this. To confirm whether there is a loyalty rewards system in place, we decided to pay their live chat a visit. While we won't go into the details on quality here, we can tell you that we did come back with some good news. While there is currently nothing being done for VIPs, the agent informed us that it was something they were looking into. We wouldn't be surprised to see an STS VIP scheme launch at some point. Rest assured that the moment it does, we'll update this section accordingly.

Customer Support – Quality Live Chat Service

STS Casino is a mixed bag in terms of customer support. We’ll say it right off the bat, the quality of their customer service is impeccable. Players with queries through live chat will be treated with professionalism and care. The support agents are knowledgeable, and quick to respond.

One small gripe we have is that live chat will be unavailable for late-night game sessions. Their working hours are from 07:00 AM to 01:00 AM. This is still excellent support coverage, hence the “minor” gripe we have. Telephone support is unavailable as well. This is not a big issue in the modern gaming market, as many players prefer live chat either way. Yet, certain customers like a more personal touch.

You can also reach the casino via e-mail at any time throughout the day. Though, response times can be up to 24 hours, which is why this option is best for non-urgent queries.

The casino site also has a detailed FAQ section, where players can get many useful answers related to payments, responsible gambling, and promotions. There is no search function, but it is well-organized through various categories.

All in all, we don’t believe you’ll run into issues in your day-to-day gaming activities at STS Bet.

What Does STS Casino Offer UK players?

STS doesn’t hide the fact they’ve gathered their full efforts in order to conquer the UK market. The site is available to residents of dozens of countries, but UK players will be in for a custom-tailored experience from top to bottom.

We can see this starting from the UK-specific welcome offer, all the way to the payment method selection supplemented by many popular e-wallets. Like we said, we would have appreciated additional incentive to customers through partnerships with the likes of Playtech or Barcrest. However, for the time being players will have to “settle” for NetEnt, Microgaming and co.

PayPal would also be a handy option to have, but several e-wallets are on offer already. Having just recently acquired a UKGC license, we have no doubts STS will expand their offering to UK players. Even now though, they’re a solid choice for customers.

STS Casino Review Verdict: A Worthy Contestant

Having just launched on the UK market, STS casino isn’t perfect out of the box. There are some issues or preferences we would like to see improved. For instance, the gaming selection is great yet it could be even better to match competitors. After all, today’s standards are at an all-time high. The welcome bonus could offer higher value, but it does come with fair wagering requirements.

The customer support team and quick access to convenient deposits/withdrawals will make sure you have a good time playing. We can’t ignore the factor of trust either. STS has quite a reputation to uphold, and we’re certain that UK players will be treated with the utmost care and respect. When all is said and done, STS has earned our recommendation. Should you decide to become their newest member today, make sure to grab your 50GBP in bonus cash along the way.
