mBit Casino is a Bitcoin casino run by Scores55 Tech B.V. Its true sister sites are 7Bit Casino, KatsuBet and RocketPlay. All four show the same operating company, the same Curaçao registration number and the same gaming licence number in their footers. That is proof they share one owner.
The proof for mBit’s sisters
mBit Casino’s footer names the operator as Scores55 Tech B.V., a company registered in Curaçao under number 162990, holding e-gaming licence OGL/2024/1307/0748. We checked other well-known crypto casinos to see which ones print that same name and those same numbers.
7Bit Casino prints the identical operating company, the identical registration number, and the identical licence number. That is a straight match, not a guess.
KatsuBet also prints the identical operating company, the identical registration number, and the identical licence number, word for word.
RocketPlay states in its own terms that it is run by Scores55 Tech B.V., company number 162990, under the same licence. That is a third confirmed match.
So mBit Casino has three confirmed sisters: 7Bit Casino, KatsuBet and RocketPlay. All four are the same business wearing four different names and four different colour schemes.
Casinos that are not sisters, even though people ask
Because these brands are all old, well-known crypto casinos, players often lump them together. We checked eight more names people commonly ask about, using each casino’s own terms and licence pages. None of them print Scores55 Tech B.V., 162990, or OGL/2024/1307/0748. Each one names a different company:
- Bitstarz is run by Gareton B.V., under its own separate licence, OGL/2024/165/0185. This company used to be linked to some of the brands above through an older Curaçao licence holder, but under the current rules it stands on its own.
- Oshi Casino names Novatrix SRL, a company registered in Costa Rica, not Curaçao, licensed by the Tobique Gaming Commission. A different set-up entirely.
- Mars Casino names Direx N.V. as its operator, a Curaçao company, but not Scores55 Tech B.V.
- Playamo also names Novatrix SRL, licensed through the Anjouan Gaming Board and the Tobique Gaming Commission.
- Joo Casino names Stable Tech N.V. as its operator, a different Curaçao company.
- Golden Star names Novatrix SRL again, the same company as Oshi and Playamo, but still not Scores55 Tech B.V.
- Betchan names N1 Interactive Ltd, a Malta-licensed company, nothing like a Curaçao set-up.
- Bob Casino also names N1 Interactive Ltd, under the same Malta licence as Betchan.
None of these eight share an owner with mBit Casino. Some of them share an owner with each other, which is a separate story, but not the one we are answering here.
A trap to watch out for: Dama N.V.
Many older crypto casinos, including some of the names above at different points in time, have printed Dama N.V. in their footer. Dama N.V. is not one casino brand. It is a licensing and platform host that dozens of unrelated casino brands have used at one time or another. Seeing “Dama N.V.” on two different casinos does not mean the same person owns both of them. It just means both casinos rented space under the same licence host, the way many separate shops can rent space in the same shopping centre.
This matters because it is weaker evidence than what we found for mBit’s sisters. A matching operating company name and a matching registration number, like Scores55 Tech B.V. and 162990, tells you the same legal business owns both sites. A shared licence host name alone does not tell you that. If you ever read that two casinos are “sisters” only because they both mention Dama N.V., treat that claim as weak, not as proof.
Slots, and who makes them
mBit Casino and its three sisters all draw from a very large shared slot library, running into the thousands of titles. The games themselves come from well-known slot studios, not from the casino itself. Expect names like Pragmatic Play, Play’n GO, Hacksaw Gaming, Evolution, BGaming, and a long list of smaller studios, alongside the shared library’s own house-branded games. Because all four sites plug into the same back-end, the slot list looks almost the same from one sister to the next, just under a different skin and colour scheme.
Remember the rule from earlier: using the same slot studios as another casino does not make two casinos sisters. Thousands of unrelated casinos all buy games from Pragmatic Play. What made mBit, 7Bit, KatsuBet and RocketPlay sisters was the matching company name, registration number and licence number, not the games.
Live dealer games
All four sisters offer live dealer tables, run by real dealers on video, streamed in real time. Expect the usual spread: live roulette, live blackjack, live baccarat and live poker, plus game-show style tables. The live studios are supplied by outside providers such as Evolution and Pragmatic Play Live, the same providers that supply hundreds of other casinos worldwide. So again, the live games are shared technology, not proof of ownership.
Signing up and ID checks
Signing up at mBit Casino, or at any of its sisters, is quick. You give an email address and a password, and you can start playing with crypto straight away, often without handing over ID first. That is normal for crypto casinos. The ID checks tend to show up later, usually when you ask to withdraw a larger amount, or if the casino’s automatic checks flag your account for any reason. When ID is asked for, it is the standard request: a photo ID and sometimes a proof of address. It is not usually a long or difficult process, but it can add a short delay to your first bigger withdrawal. Smaller, routine withdrawals are often processed with no ID request at all.
Coins accepted and withdrawal speed
mBit Casino and its sisters accept a wide range of coins. Bitcoin, Ethereum, Litecoin and USDT are all supported, along with a growing list of other coins on most of these sites. Crypto deposits land in your account almost straight away, since they only need a small number of network confirmations. Withdrawals in crypto are generally fast too, often paid out within minutes to a few hours once approved, which is much quicker than the days a bank transfer can take at a traditional online casino. Speed can still vary a little by coin, by network traffic, and by whether your account has been asked for ID.
Bottom line
mBit Casino has three real sisters: 7Bit Casino, KatsuBet and RocketPlay. All four are owned and run by Scores55 Tech B.V., proven by the matching registration number 162990 and the matching licence number OGL/2024/1307/0748 printed on each site. Bitstarz, Oshi, Mars Casino, Playamo, Joo, Golden Star, Betchan and Bob Casino are not part of this group, no matter how similar they look or how many of the same slot studios they use. If you already play at one of the three confirmed sisters, the others will feel familiar, since they share the same games, the same live tables, and the same coins. If you play at any of the eight other casinos instead, know that you are dealing with a different company, a different licence, and a different set of rules, even if the names sound like they belong together.
