What Are Cosmobet Casino Sister Sites?
Cosmobet Casino’s sister sites are other gambling platforms run by Santeda International B.V., all operating under Curaçao licensing—not the UK Gambling Commission.

Definition and Overview
Sister sites basically share the same parent company and backbone. Cosmobet runs alongside several others under Santeda International B.V.
The main ones? MyStake Casino, GoldenBet, Rolletto, DonBet, and Velobet. There’s a similar vibe and feature set, but each keeps its own personality.
Expect comparable game selections and promo structures. Payment methods and customer support won’t throw you any curveballs across the network.
These sites often share player databases and loyalty schemes. So, if you get a bonus or a restriction on one, odds are it’ll carry over to the others.
Because they share the same systems, the service quality stays pretty consistent. If you hop between sister sites, the interfaces and gameplay will feel familiar.
Santeda International B.V. and Operator Details
Santeda International B.V. is the Curaçao-based parent company behind Cosmobet and its sister platforms.
They launched Cosmobet Casino in 2023, making it one of their newer projects. MyStake Casino is the veteran of the bunch and probably the best known.
MyStake Casino made its name in sports betting and casino games. Its success helped boost the credibility of the newer sites, including Cosmobet.
Each site keeps its own branding, but the nuts and bolts—payments, games, support—are all run through the same infrastructure.
The company mostly targets markets outside the UK. By sticking with Curaçao licensing, they can serve players internationally.
Licensing and Regulation Notes
All Cosmobet sister sites run under Curaçao licensing, not the UK Gambling Commission. That’s a big deal for player protections.
Curaçao regulations aren’t as strict as the UK’s, especially around dispute resolution and compensation. The safety net for players just isn’t the same.
UK players can sign up, but these sites aren’t under UKGC rules. That means UK-specific protections like GAMSTOP exclusions don’t apply here.
This setup lets the sister sites offer promos you won’t find at UK-licensed casinos, but you’ll be trading off some regulatory oversight and consumer safety.
Santeda International B.V. keeps the same licensing model for all its sites, so you’ll get similar standards across the board—though not the same accountability you’d find with UKGC casinos.
List of Cosmobet Casino Sister Sites
Cosmobet’s network includes several sister casinos run by Santeda International B.V. The big names are MyStake Casino, GoldenBet Casino, and Rolletto Casino. You’ll see a lot of overlap in features, payments, and games, but each site has its own branding and promotional flavor.
MyStake Casino
MyStake Casino is the old hand in the Santeda International B.V. family, having launched in 2019. It’s packed with slots and live dealer games for players who want variety.
It’s got a 4.6 Trustpilot score from more than 21,000 reviews—a solid reputation. New players can grab a 150% welcome bonus up to £300 if they deposit at least £20.
Wagering requirements sit at 30x the bonus before you can cash out. The casino runs on a Curaçao eGaming license, so it ticks the compliance boxes.
The slots selection is broad, and the live casino section is pretty robust. Payments? You can use the usual banking methods or go crypto if that’s your thing.
GoldenBet Casino
GoldenBet Casino arrived in 2021 and quickly carved out a spot as a trusted option. New players get a 100% welcome bonus up to £500 with a £25 minimum deposit.
It holds a 4.1 Trustpilot rating from over 1,300 reviews. Wagering on promos is set at 35x the bonus.
GoldenBet serves up a wide mix of slots, table games, and live dealer experiences. The layout makes it easy to jump between game categories.
Deposits go through instantly, and withdrawals usually take one to three business days, depending on your chosen method.
Rolletto Casino
Rolletto Casino, launched in 2022, is one of the newer faces in the Cosmobet network. New signups can claim a 175% welcome bonus up to £6,500.
You’ll need a minimum £20 deposit, and the bonus comes with a 35x wagering requirement. Trustpilot gives Rolletto a 2.9 score from more than 1,100 reviews—mixed, but not uncommon for newer sites.
Rolletto’s got thousands of slots, plenty of table games, and a decent live casino section. The interface is user-friendly and works well on mobile.
Deposits are instant no matter how you pay. Withdrawals usually land in your account within one to three business days after you’ve been verified.
Key Features of Sister Sites
Cosmobet’s sister sites have a lot in common but still manage to keep their own flavor. You’ll find generous welcome bonuses, strong sports betting options, big game libraries, and interfaces designed for easy use.
Welcome Bonus and Promotions
Most of these sites offer first deposit bonuses ranging from 100% up to 200%. MyStake, for example, has solid welcome packages with deposit matches and free spins on popular slots.
Rolletto leans into daily cashback and tournament promos more than the others. If you like ongoing deals, it’s worth a look.
Goldenbet gives 10% cashback on all daily losses—no upper limit. That’s a nice perk, especially for high-stakes players.
Velobet goes after sports fans with free bet offers for every four bets placed. It’s a niche, but some punters swear by it.
Most sites set wagering requirements between 30x and 35x on bonus funds. Minimum deposits to trigger these offers usually fall between £10 and £20.

Sports Betting and Sportsbooks
Sister sites really shine in sports betting. Velobet is probably the most sports-focused, with a slick interface built for punters.
Football betting is a big deal across the board, covering everything from the Premier League to international matches.
MyStake mixes classic casino games with a full-featured sportsbook—football, tennis, basketball, esports, you name it.
Live betting is available everywhere, with in-play odds that update in real time.
Another plus: most of these sites accept crypto for betting. Bitcoin, Ethereum, and the usual suspects are all supported for deposits and withdrawals.
Slots and Game Variety
There are more than 1,000 slots on offer, with big names like Pragmatic Play providing hits such as Sugar Rush, Gates of Olympus, and Wolf Gold.
The live casino sections are solid, too. You’ll find blackjack, roulette, baccarat, and game shows with real dealers.
Some sites throw in mini-games and exclusives—Plinko, for example—for a bit of variety.
Donbet stands out with its mafia-themed graphics and unique game presentation, though the actual game list stays pretty much the same.
Most welcome bonuses come with free spins—usually 30 to 50 on selected slots when you make your first deposit.
Game filtering is decent. You can sort by provider, theme, popularity, or see what’s new.

User Experience and Accessibility
User experience does shift a bit between sites, even though the tech stack is similar. MyStake’s interface feels polished and easy to use.
Mobile play is solid across the network. All sites use responsive design, so they look and work fine on phones and tablets.
Signing up is quick and painless—just a few steps and standard verification.
Rolletto’s visuals are a bit more basic, but it still gets the job done and matches the performance of its siblings.
Withdrawals usually take about three days, no matter which method you use. That’s pretty much the standard across these sites.
Customer support is available via email and live chat, with most sites offering 24/7 help in multiple languages, including English.
Banking Options and Responsible Gaming
Cosmobet’s sister sites let you pay with crypto, e-wallets, or debit cards, and withdrawals are pretty speedy. They’ve got responsible gambling tools in place, plus high deposit limits and tempting crypto welcome bonuses.
Payment Methods and Currencies
Payment options are flexible. Cryptocurrency is big here—Bitcoin, Ethereum, and USDT are all accepted.
If you prefer the old-school route, debit cards from Visa and Mastercard are fine. E-wallets like Skrill, Neteller, and PayPal also work for quick transactions.
Most sites deal in GBP, EUR, and USD. Some add Canadian dollars or other regional choices.
If you deposit with crypto, you might get a crypto welcome bonus up to 200% on your first deposit. That usually applies to Bitcoin, Ethereum, and the rest.
Minimum deposits start at £10 for most payment types. Crypto might have slightly higher minimums, depending on network fees.
Withdrawal Speeds and Deposit Limits
Withdrawals for verified accounts usually process within 2 to 24 hours. Crypto withdrawals are often the fastest—sometimes just an hour or two.
E-wallet cash-outs typically take 12 to 24 hours. Bank transfers can drag on for 2 to 5 business days, depending on your bank.
Deposit limits depend on your payment method and account status. Regular users can usually put in up to £5,000 per transaction, while VIPs can ask for more through support.
Monthly deposit limits are between £10,000 and £25,000 for most players, but high-rollers can request higher caps after verification.
Withdrawals start at £2,000 per day for new accounts, with up to £5,000 daily for verified users.
Responsible Gambling Tools
All sister sites offer a solid set of responsible gambling features. You can set daily, weekly, and monthly deposit limits right from your account settings, so it’s pretty easy to stay in control.
Self-exclusion options let you take a break—anything from just 24 hours to shutting down your account for good. If you just need some time out, cooling-off periods run from a single day up to 6 months.
Reality check notifications pop up to remind you how long you’ve been playing. You can tweak how often these alerts appear, which is helpful if you lose track of time.
Cashback bonus programs soften the blow of losses a bit by giving back a chunk of your net losses. Usually, weekly cashback falls between 5% and 15%, depending on your VIP level.
Loss limits let you cap how much you can lose over a set period. Once you set these, you can’t just bump them up on a whim—they’re locked in for your protection.
The sites work with GamCare and BeGambleAware to offer extra support. You’ll find links to professional help in every page footer, just in case you need them.
