If you’ve played at 7Bit Casino, you’ve probably noticed KatsuBet and Mirax look familiar. They’re related, and the paperwork shows it. I tested all three with real money, so this page answers the question people actually ask: if they’re sister sites, does it matter which one I use?
It does. They share licence links, but their withdrawal caps, bonus rules and void clauses are different enough to move the scores. KatsuBet scores 6.1/10, 7Bit 5.9/10 and Mirax 5.8/10 under our How We Rate method. All three sit below 7, the level our method gives a typical licensed casino with fair terms that paid out, and I’ll be upfront about why.
How I know they’re related
I don’t rely on rumour for this. My Mirax review describes Mirax as a sister site of 7Bit, and my KatsuBet review calls KatsuBet another 7Bit sister site. The licence records back that up. 7Bit’s terms name Kika Technology B.V. under Curaçao licence OGL/2023/147/0081, and the Curaçao register lists both katsubet.com and miraxcasino.com under that same Kika licence. KatsuBet and Mirax also name the same operator in their own terms: Scores55 Tech B.V., Curaçao reg. 162990, Scharlooweg 39, Willemstad.
| Casino | Licence named in its terms | What else the register shows |
|---|---|---|
| 7Bit Casino | Varies by region: Kika Technology B.V., Curaçao OGL/2023/147/0081, or Saphirix Solutions SRL, Tobique Gaming Commission no. 0000091 | Neither register could be re-checked on 15 Oct 2026 |
| KatsuBet | Scores55 Tech B.V. (Curaçao reg. 162990), OGL/2024/1307/0748, listed active | katsubet.com is also listed under Kika Technology B.V., OGL/2023/147/0081 |
| Mirax Casino | Scores55 Tech B.V. (Curaçao reg. 162990), OGL/2024/1307/0748, listed active | miraxcasino.com is also listed under Kika Technology B.V., OGL/2023/147/0081 |
That’s why all three score exactly 6.0 for licence and safety. A named operator and an active Curaçao licence count in their favour. Having the domain listed under two operators, or the operator varying by region, holds them back. I’ll re-check the registers on the next re-test.
How I tested them
Same routine for each: I deposited $100 in BTC, played at small stakes and withdrew in BTC. All three withdrawals arrived within the casino’s stated timeframe. The 7Bit test was confirmed on 15 Oct 2026 and the KatsuBet and Mirax tests on 16 Oct 2026. Games and support are still provisional for all three. I haven’t documented lobby sizes or tested support yet, so those rows don’t separate them.

Pick by what you’ll actually do
Because these three are so alike on paper, the right one depends on how you play. Here’s how I’d choose.
You plan to claim the welcome bonus: 7Bit
7Bit has the only bonus terms of the three where I found no discretionary-void clause, so it scores 6.0 for bonus terms against KatsuBet’s 4.5 and Mirax’s 4.0. It’s still 35x within 14 days. Only slots count fully: other games count 5% and live casino 0%. A 100 bonus means 3,500 in bets within two weeks, so treat it as a slots-only offer. If you want lighter wagering than any of these, see low-wagering crypto casino bonuses.
You might hit a big win: KatsuBet or Mirax
This is 7Bit’s weak spot. Its withdrawals are capped at 0.12 BTC a week and 0.48 BTC a month, with larger balances paid in instalments (terms 9.10-9.11). That’s below our method’s threshold, so its payouts score is capped at 5.0. KatsuBet and Mirax both allow EUR 10,000 a week and EUR 40,000 a month, which most players won’t hit. Big wins at either still arrive in monthly instalments over EUR 40,000.
You skip bonuses and just want the best overall score: KatsuBet
KatsuBet’s 6.1 comes mainly from its higher payouts score (6.5). Its bonus terms are the heaviest of the three, though: 45x for high rollers, 50x on no-deposit spins, and a clause letting it cancel bonuses and winnings at its sole discretion if it suspects delayed rounds. If you play without a bonus, most of that doesn’t apply to you. Bear in mind KatsuBet has the lowest confidence rating of the three (medium-low), because its KYC and dormancy terms aren’t itemised in my review yet.
You play table or live games with fresh deposits: not Mirax
Mirax requires every deposit to be wagered 3x before withdrawal, rising to 10x on table and live games. Add a bonus cashout cap of 10x your deposit, a void-“if necessary” clause and a dormancy fee of at least EUR 25 a month after 12 months idle, and it lands last at 5.8. My review’s “best for” line is slot players who skip bonuses or read them closely, and I’d stick to that.
What the public record says
I only have a compiled complaint record for 7Bit. Casino.guru gives it a very high Safety Index of 9.5, with 102 complaints, a “very good” complaints ratio and no unfair terms found. AskGamblers players rate it 7.7/10 from 260 reviews, and it holds 4.3/5 on Trustpilot from about 1,900 reviews. I haven’t compiled KatsuBet’s or Mirax’s records yet, so I won’t assume 7Bit’s reputation carries over to its sisters.
My ranking
- KatsuBet, 6.1/10: the same workable withdrawal caps as Mirax and the highest payouts score of the three. Skip the bonuses.
- 7Bit Casino, 5.9/10: the cleanest bonus terms of the family, the longest track record and a strong public record, but the tightest withdrawal caps.
- Mirax Casino, 5.8/10: fine for slots without a bonus. The deposit rollover and void clause weigh on it.

FAQ
Are KatsuBet and Mirax really 7Bit sister sites?
My reviews describe them that way, and the Curaçao register lists both katsubet.com and miraxcasino.com under Kika Technology B.V. (OGL/2023/147/0081), the company 7Bit’s terms name. KatsuBet and Mirax also name the same operator, Scores55 Tech B.V.
Can I use one account across all three?
My reviews don’t cover shared accounts. Treat each as a separate casino with its own sign-up, terms and verification.
Which sister site has the lowest wagering?
All three use 35x as the standard bonus wagering. 7Bit is the only one where I found no discretionary-void clause, which is why its bonus terms score highest.
Did all three pay out in your test?
Yes. Each $100 BTC withdrawal arrived within the casino’s stated timeframe.
