7Bit Casino has three confirmed sister sites: mBit Casino, KatsuBet, and RocketPlay. All four share the same operator, Scores55 Tech B.V., with the same Curaçao registration number and licence. That matching paperwork is strong proof of one shared owner.
What counts as a sister site
A sister site is a casino that shares a back-end platform with another casino, or shares an owner with it. That is the only rule we use here. Two casinos that just look alike, or use the same slot supplier, are not sisters. Almost every crypto casino uses some of the same big slot makers, like Pragmatic Play or Evolution. That does not make them sisters, it just means they bought games from the same factory.
The strongest proof of a shared owner is a matching company name and a matching government registration number in the small print at the bottom of the site. A company cannot have two different registration numbers. If two casinos show the exact same company name and number, they are, in plain terms, the same business wearing two different names. That is far stronger proof than two sites just looking similar or running on the same software.
The proof behind mBit, KatsuBet and RocketPlay
7Bit Casino’s footer names its operator as Scores55 Tech B.V., registered under number 162990 at Scharlooweg 39, Willemstad, Curaçao, with gambling licence OGL/2024/1307/0748 from the Curaçao Gaming Authority. mBit Casino’s footer names the exact same operator, the exact same registration number, and the exact same licence number. KatsuBet’s own terms page names the exact same operator, address, registration number, and licence too. RocketPlay’s own terms carry the same operator name, the same registration number, and the same licence number, word for word and digit for digit. Nothing is different between any of the four.
Four different websites, four different names, one company standing behind all of them, proven by paperwork rather than a guess. That is as close to a signed confession as a website can give you. They are run by the same people.
A trap to watch out for: Dama N.V.
Many crypto casinos put the name “Dama N.V.” in their footer as their licence holder. This trips people up. Dama N.V. is not one casino brand. It is a licensing and hosting company that lets dozens of unrelated brands use its Curaçao licence. Two casinos both naming Dama N.V. does not mean they share an owner, it only means they rent their paperwork from the same landlord.
This is weaker evidence than what we found for mBit, KatsuBet and RocketPlay. A shared licence host is common across the crypto casino world. A shared operating company and a shared registration number is not. That is the whole difference between weak evidence and strong evidence, and why we treat the Scores55 Tech B.V. matches differently from a simple “both use Dama N.V.” match.
Checking the other well-known crypto casinos
We also checked eight other crypto casinos that people often lump in with 7Bit, looking for the same operator name, the same registration number 162990, or the same licence OGL/2024/1307/0748. None of them matched. Here is what each one actually shows.
- BitStarz – Not a sister. Named operator is Gareton B.V., licence OGL/2024/165/0185. It sat under the old Dama N.V. umbrella years ago, but now runs under its own separate company.
- Joo Casino – Not a sister. Named operator is Stable Tech N.V., a different company with a different Curaçao registration.
- PlayAmo – Not a sister. Its own pages point to Dama N.V. as licence holder, the weaker link explained above, not a match to the Scores55 Tech B.V. paperwork.
- Oshi Casino – Not a sister. Named operator is Novatrix S.R.L., licensed in a different jurisdiction with a completely different licence number.
- Golden Star Casino – Not a sister. Also names Novatrix S.R.L., making it a sister to Oshi Casino, but not to 7Bit.
- Mars Casino – Not a sister, and worth a separate warning: review sites now report Mars Casino has closed down and is no longer operating. Skip it either way.
- Betchan – Not a sister. Named operator is N1 Interactive Ltd, licensed by Malta, not Curaçao at all.
- Bob Casino – Not a sister. Also names N1 Interactive Ltd, making it a sister to Betchan, but not to 7Bit.
So the plain answer is this: 7Bit has three proven sisters, not one, making four brands under Scores55 Tech B.V. The other seven brands still standing are separate businesses with their own operators and licence numbers. Some are sisters to each other, just not to 7Bit.
The slots, and who makes them
None of the four sister sites builds its own games. All four buy them from outside studios, the same way almost every online casino does. Here is the game count and main studios for each one:
- 7Bit Casino – over 10,000 games from more than 100 studios, including NetGame Entertainment and Belatra.
- mBit Casino – around 5,000 games from more than 40 studios, including Pragmatic Play, Evolution, Play’n GO, Yggdrasil, and Hacksaw Gaming.
- KatsuBet – over 7,000 games from studios such as BGaming, GameBeat, Platipus, KA Gaming, Belatra, Pragmatic Play, Yggdrasil, and Play’n GO.
- RocketPlay – games from more than 100 providers, covering slots, table games, video poker, bingo, and jackpot games.
Sharing these suppliers is normal and is not, on its own, a sign of shared ownership. It is the paperwork, not the game list, that proves this group is real.
Live dealer games
All four sites have a live dealer section with real people running the tables:
- 7Bit Casino – live blackjack, roulette, and more, from providers such as Live88 and Plati+.
- mBit Casino – close to 500 live tables from Evolution and Pragmatic Play, plus more than 60 extra tables from Ezugi.
- KatsuBet – live roulette, blackjack, poker, and more.
- RocketPlay – live baccarat, blackjack, roulette, poker, dice, and bingo.
If live dealer variety matters most to you, mBit currently has the widest spread of live tables. If you want the largest overall game count, 7Bit has more titles in total once you include slots.
How much hassle the ID checks are
7Bit Casino lets you sign up with just an email address, and you can often deposit and play straight away with crypto. Full ID checks, meaning a copy of your ID and proof of address, usually only come up once you try a larger withdrawal, use a card or bank transfer, or if the site flags your account for review.
mBit Casino, KatsuBet, and RocketPlay work the same way. All three are built to be easy for crypto players to join, so none push hard for documents up front. A bigger cash-out can still trigger an ID request before the money is sent, so keep a clear photo of your ID and a recent bill handy. That is normal at almost every licensed casino, not just this group.
Crypto and card payments, and withdrawal speed
All four sites take crypto, but they differ on cards and on speed:
- 7Bit Casino – crypto (Bitcoin, Ethereum, Litecoin, Dogecoin, Bitcoin Cash, Tether, Ripple, Tron, Cardano, BNB) plus Visa, Mastercard, bank transfer, Skrill, and Neteller. Crypto withdrawals often land in under 20 minutes; card and bank withdrawals take one to five business days.
- mBit Casino – crypto only (Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Ripple, Dogecoin, Tether), with no card or bank transfer option at all. Withdrawals are usually sent within about ten minutes, the fastest of the four.
- KatsuBet – crypto (Bitcoin, Litecoin, Ethereum, Dogecoin, Tether) plus Visa, Mastercard, and Maestro. Some payouts land within hours; card and bank routes can take up to five days.
- RocketPlay – crypto (Bitcoin, Ethereum, Litecoin, Dogecoin) plus Skrill, Neteller, Paysafecard, Visa, Mastercard, Apple Pay, and bank transfer. Crypto withdrawals typically land within a couple of hours; card withdrawals take longer.
So the payment choice comes down to this: pick 7Bit, KatsuBet, or RocketPlay if you sometimes want to pay by card as well as crypto. Pick mBit if you only ever plan to use crypto and want the fastest possible cash-out.
Bottom line
7Bit Casino has three real sister sites, backed by hard proof: mBit Casino, KatsuBet, and RocketPlay. All four share the exact same operator, Scores55 Tech B.V., the same Curaçao registration number, 162990, and the same licence, OGL/2024/1307/0748. That is genuine, checkable proof of one shared owner, not a guess based on looks or a shared game supplier.
BitStarz, PlayAmo, Joo Casino, Oshi Casino, Golden Star, Betchan, and Bob Casino are not part of this group, and Mars Casino has closed down entirely. Each remaining brand is run by its own separate company with its own licence number, even though several are sisters to each other. If you enjoy 7Bit’s slot range and its mix of crypto and card payments, mBit, KatsuBet, or RocketPlay are the true sisters worth trying, depending on whether you want an all-crypto site with the fastest cash-out, or one that still lets you pay by card.
