What Are Betmaster Sister Sites?

Betmaster Sister Sites are online casinos that share the same operator, licence, or technical infrastructure as Betmaster. In this case, Betmaster is operated by Santeda International B.V. under a Curaçao Gaming licence. Every casino on this licence — or built on the same platform — qualifies as a Betmaster sister site.

Finding betmaster sister sites matters because sister casinos often share bonus policies, payment methods, game libraries, and support systems. If you enjoy playing at Betmaster, you’ll likely enjoy its sister casinos too. Conversely, if you’ve reached a bonus limit or have an active self-exclusion at Betmaster, that restriction may carry over to the betmaster sister sites listed here.

Our Casino Sultan team has reviewed each of the betmaster sister sites above, checking their licences, bonus terms, withdrawal speeds, and game selections. We only include sites we’d genuinely recommend to UK players.

Why Betmaster Has So Many Sister Sites

The Curaçao iGaming industry operates under a shared-licence model. When one operator like Santeda International B.V. secures a master gaming licence, they can launch multiple casino brands under that single licence without applying separately for each one. This is how betmaster sister sites multiply so quickly.

This model benefits players in some ways — shared infrastructure usually means robust payment systems, well-tested game integrations, and established support teams. It can also mean shared bonus abuse detection, so playing at multiple betmaster sister sites simultaneously may flag your account.

From a regulatory standpoint, a single operator holding multiple licences under one umbrella means all betmaster sister sites are held to the same compliance standards. If one site gets flagged for malpractice, it can affect the entire network.

How We Reviewed These Betmaster Sister Sites

Every casino in our betmaster sister sites list has been manually tested by the Casino Sultan team. Here’s what we check before adding any site to our listings:

Licence Verification

We verify each casino’s licence directly with the issuing authority. All betmaster sister sites carry a valid Curaçao licence issued by the Curaçao Gaming Control Board or equivalent authority. We check the licence number matches and that it hasn’t been suspended or revoked.

Bonus Terms

We read every line of the bonus terms before listing a site. We flag hidden wagering requirements, restrictive game weightings, and unfair maximum win caps. All betmaster sister sites listed above have bonus terms we consider fair and transparent.

Payment Methods

We test deposits and withdrawals personally. For betmaster sister sites, we look specifically at whether UK-friendly payment methods like Visa, Mastercard, and e-wallets work without issues, and how quickly withdrawals are processed. Most betmaster sister sites process withdrawals within 24–72 hours.

Game Selection

A wide game library from reputable providers — NetEnt, Pragmatic Play, Evolution Gaming, Play’n GO — is a strong signal of a legitimate operation. All betmaster sister sites above offer slots, live casino, and table games from licensed software providers.

Comparing the Best Betmaster Sister Sites

The table below gives a quick comparison of the top betmaster sister sites so you can find the best fit for your playing style.

Are Betmaster Sister Sites Safe for UK Players?

This is the most important question. All the betmaster sister sites on this page operate under a Curaçao licence, which means they are internationally licensed but not regulated by the UK Gambling Commission (UKGC). This is an important distinction.

UK players can legally access Curaçao-licensed casinos, but these sites fall outside the UKGC’s consumer protections — things like mandatory affordability checks, self-exclusion integration with GamStop, and the Financial Services Compensation Scheme don’t apply.

For players who have self-excluded via GamStop, betmaster sister sites may still be accessible since Curaçao-licensed casinos are not required to check the GamStop register. However, we strongly advise responsible gambling. If you’re struggling with gambling, please visit BeGambleAware.org for free, confidential support.

For players simply looking for more variety outside UKGC-regulated sites, betmaster sister sites offer a legitimate option provided you gamble responsibly and understand the regulatory differences.

Bonuses at Betmaster Sister Sites

Welcome bonuses at betmaster sister sites tend to follow similar patterns to Betmaster itself — typically a matched deposit bonus combined with free spins. Here are some tips for getting the most value:

Check Wagering Requirements First

A 100% bonus sounds great, but a 60x wagering requirement makes it nearly impossible to withdraw. For betmaster sister sites, we recommend bonuses with wagering requirements of 35x or lower. All sites listed above meet this threshold.

Look for Low Minimum Deposits

Most betmaster sister sites require a minimum deposit of just €10 to activate the welcome bonus, making them accessible for casual players testing a new site without committing large sums.

Free Spins Value

Free spins included with welcome packages at betmaster sister sites are typically valued at €0.10–€0.20 per spin. Multiply the number of free spins by the value to calculate the realistic bonus amount before wagering.

How to Choose Between Betmaster Sister Sites

With multiple betmaster sister sites available, the best choice depends on your priorities:

Best Bonus Value

Compare the raw bonus amount against wagering requirements. A smaller bonus with lower wagering often beats a large bonus with restrictive terms.

Best for Live Casino

If live dealer games are your preference, look for betmaster sister sites powered by Evolution Gaming or Ezugi — these providers offer the most professional live dealer experiences.

Best for Crypto Players

Several betmaster sister sites accept Bitcoin, Ethereum, and other cryptocurrencies. If you prefer crypto deposits and withdrawals, check the cashier section before registering.

Best for Sports Betting

Some betmaster sister sites also offer sportsbooks alongside their casino sections. If you want both under one account, look for those with integrated betting products.
