Katsubet sister sites are 7BitCasino, mBitCasino, Mirax and RocketPlay. All five are operated by Scores55 Tech B.V., registered in Curaçao under number 162990 at Scharlooweg 39, Willemstad, with licence OGL/2024/1307/0748.
The five run on one licence and one platform, so the useful question is not who owns them but what each set of terms lets you do. On that they split sharply – one of them caps your bet at a fifth of what the others allow, and two of them will not take Australian players at all.
🎰 The five brands, where they differ
| 🎲 Brand | 🔄 Welcome wagering | 💰 Max bet on bonus | 💸 Weekly cap | 💳 Min withdrawal |
|---|---|---|---|---|
| Katsubet | 35x | €5 | €10,000 | €20 |
| Mirax | 35x | €1 | €10,000 | €20 |
| RocketPlay | 40x | €5 | €5,000 | €25 |
| 7BitCasino | Not stated in the terms | Not stated | 0.12 BTC | 0.24 mBTC |
| mBitCasino | Not stated in the terms | Not stated | 3 BTC per 7 days | Not stated |
Katsubet and Mirax read as the same casino on paper until the max bet line. Same wagering, same caps, same minimum. One lets you clear at €5 a spin, the other at €1.
🏢 Who runs Katsubet
Clause 1.2 of the terms names Scores55 Tech B.V., registered under number 162990 at Scharlooweg 39, Willemstad, Curaçao, holding licence OGL/2024/1307/0748. The same registration number and the same licence number appear in the terms of all five brands. That is what ties them together – not a shared look, not a shared affiliate programme.
One wrinkle worth knowing. Katsubet’s and Mirax’s terms call the regulator the Curaçao Gaming Authority. 7BitCasino’s and RocketPlay’s call it the Curaçao Gaming Control Board. Same body, same licence number, two names for it across documents built from one template.
Katsubet came out of the Dama N.V. break-up, along with 7BitCasino and mBitCasino. The full account of where those brands went covers who ended up with what.
🎁 The welcome package
Four deposits, each needing a promo code after the first.
- 🥇 First deposit – 100% up to 1.5 BTC / €400 / A$400 / $400, plus 100 free spins on Aloha King Elvis. Minimum deposit €20.
- 🥈 Second deposit – 75% up to 1.25 BTC / €600, plus 100 free spins on Wild Cash x9990. Code 2DEP.
- 🥉 Third deposit – 50% up to 1.25 BTC / €1,000. Code 3DEP.
- 🎊 Fourth deposit – 100% up to 1 BTC / €4,000. Code 4DEP.
Wagering is 35 times the bonus. The maximum bet while a bonus is live is €5. A bonus expires after 14 days if the wagering is not covered, and free spin winnings cap at €100.
What that comes to: a €400 first-deposit bonus at 35x is €14,000 of turnover, at no more than €5 a spin. That is 2,800 spins as an absolute floor, inside fourteen days.
💰 Withdrawals
Minimum €20. Maximum €10,000 a week and €40,000 a month, with anything above the monthly figure paid in instalments. VIP exceptions are at the casino’s discretion.
Against the group, that is the joint highest ceiling – level with Mirax and double RocketPlay on both the weekly and the monthly.
Separately, deposits carry their own wagering before they become cashable: 3 times on slots, 10 times on table and live games. That applies whether or not you took a bonus, and it is the clause people miss.
🌎 Where each brand takes players
This is the sharpest split in the group, and the one most lists get wrong by treating the five as interchangeable.
7BitCasino’s restricted list names Australia, the United Kingdom, the United States and Sweden. Katsubet, Mirax and RocketPlay do not restrict Australia – all three run AUD accounts and take Australian players.
Katsubet’s own list runs past 180 jurisdictions and includes the United States, the United Kingdom, France, the Netherlands and Belgium. Sweden can open an account but is excluded from every bonus.
💵 Currencies
Katsubet runs EUR, USD, AUD, CAD, NZD, NOK and PLN, plus BTC, LTC, ETH, DOGE, BCH, USDT, XRP, TRX, ADA and BNB.
mBitCasino is the outlier: crypto only, no fiat accounts at all. If you want a euro or dollar balance, it is the one brand of the five that cannot give you one.
🎯 Which of the five suits you
- 🎰 Katsubet – the highest withdrawal ceiling in the group with a workable €5 max bet. The four-deposit package is the longest on offer here.
- ⭐ Mirax – identical terms and identical caps, but the €1 bet limit means the same 35x takes at least five times as many spins.
- 🚀 RocketPlay – a shorter two-deposit package, 40x rather than 35x, and five days to clear rather than fourteen. Lower caps too.
- ₿ 7BitCasino and mBitCasino – crypto-denominated limits and the older brands of the set, but check the restricted list first if you are in Australia.
❓ Katsubet sister sites FAQ
📜 Does Katsubet have sister sites?
Yes. 7BitCasino, mBitCasino, Mirax and RocketPlay all name Scores55 Tech B.V., registration 162990, and licence OGL/2024/1307/0748 in their own terms.
💵 Can I use one account across all five?
No. Each brand is a separate registration with its own verification, and each welcome package is claimed separately.
🎉 Which sister site has the best welcome offer?
Katsubet’s runs across four deposits at 35x with a €5 bet cap, which is the most generous combination of the five. Mirax matches the headline but restricts bets to €1.
🌐 Was Katsubet a Dama N.V. brand?
It was. Dama N.V. was declared bankrupt in Curaçao in June 2024 and the brands were split between several companies. Katsubet went to Scores55 Tech B.V. alongside 7BitCasino and mBitCasino, while BitStarz went to Gareton B.V. on its own.
