Donbet sister sites are the other casinos run by Santeda International B.V. — the Curaçao-licensed operator behind Donbet — and the good news for anyone searching this is that they're brands we know well and rate highly. Donbet's closest siblings are Cosmobet, Velobet, and Rolletto, with MyStake and Goldenbet also reported in the group. This page lays out the real network, what Donbet itself offers, how the sisters differ, and where each one fits — no guesswork about who owns what, because here the ownership is clear.
Who Operates Donbet?
Donbet is operated by Santeda International B.V., a Curaçao-licensed company that also runs Cosmobet, Velobet, and Rolletto. That's the honest network story — and unlike a lot of casino groups, it isn't a mystery. Donbet's sisters are genuine Santeda-family brands, several of which are among the highest-rated casinos we review. That makes "Donbet sister sites" a rare case where the network is both real and worth joining.
Santeda is an established multi-brand operator, and that scale is itself a trust signal: a company running several casinos on a shared setup has more reputation exposed than a one-brand outfit that could disappear overnight. Donbet holds a Curaçao licence, as do its siblings — so the whole group sits on the same regulatory footing.
All Donbet Sister Sites Listed
Donbet's Santeda siblings are Cosmobet, Velobet, and Rolletto, with MyStake and Goldenbet also reported in the group. Cosmobet is the standout — our highest-rated of the family — so it leads the list. Each sibling shares Donbet's operator and Curaçao licensing but carries its own bonus and positioning.
Cosmobet — the lead pick. Cosmobet is the sister we rate highest across the whole group, with a 750% welcome package up to €7,000 plus 1,000 free spins and 15% cashback, and one of the best ratings we've given (9.8). If you like Donbet and want the strongest brand in its family, this is the one to open first — see the Cosmobet review and its Cosmobet sister sites breakdown.
Velobet. Velobet carries the largest headline cap in the family — a 700% package up to €7,500 plus 1,000 free spins and 25% cashback — which makes it the pick for a player chasing the biggest possible welcome within the Santeda group. Full detail is in the Velobet review.
Rolletto. Rolletto is the more restrained option, with a 330% package up to €3,000 plus 50 free spins — a smaller, simpler offer for players who don't want a huge multi-tier chase. See the Rolletto review.
MyStake and Goldenbet. Both are also reported Santeda siblings. MyStake is the most established and widely-recognised name in the reported group, and has its own MyStake sister sites breakdown; Goldenbet is a closely associated sibling brand. We name them as part of the family but don't quote specs for them we can't stand behind.
How Are Donbet's Sister Sites Connected?
The connection is straightforward: they're run by the same operator. Donbet, Cosmobet, Velobet, and Rolletto are all Santeda International B.V. brands on Curaçao licences, so they share a company and a regulatory footing rather than just a passing resemblance. That's a firmer link than most "sister site" claims, which rest on inference.
What that means in practice is worth being precise about. Sharing an operator tends to mean a broadly similar cashier and a familiar feel moving between the brands — but we won't quote a game-overlap percentage or claim an identical player database, because those specifics aren't ours to state. The practical takeaway for a player: because it's one company across the family, account decisions and bonus-abuse rules can apply at group level, so treat the family as connected rather than assuming each brand is fully walled off from the others.
Donbet Bonus vs Sister Site Bonuses
Donbet's welcome offer is 150% up to €750 plus 50 free spins — a modest, clean package that sits well below its bigger siblings. Within the family, Velobet has the largest cap (€7,500) and Cosmobet the highest match and rating, so Donbet is the entry-level option rather than the headline act. 18+, terms apply.
The single figure to work with for Donbet is 150% up to €750 plus 50 free spins. Older write-ups quoted much larger numbers for Donbet; those are wrong, and we don't repeat them. It's a smaller welcome than Cosmobet's 750% up to €7,000 or Velobet's 700% up to €7,500 — so if bonus size is the deciding factor, the siblings outrank the anchor here.
Where Donbet earns its place is as a straightforward member of a strong family: a smaller bonus, but the same operator and licensing as the higher-rated brands beside it. As always, confirm the live wagering and max-bet terms on Donbet's own promotions page before claiming.
Is Donbet Safe? Licence and Player Protection
Donbet holds a Curaçao licence and is backed by Santeda International B.V.'s track record across several brands — a genuine reassurance, since the operator has multiple reputations riding on how it treats players. Curaçao oversight sits below the UKGC standard, which is a factual difference worth knowing, not a mark against Donbet specifically. The multi-brand family is part of what makes it a reasonable choice.
The Santeda group's scale cuts in the player's favour here: a payout dispute at Donbet is a dispute with a company that also runs Cosmobet, Velobet, and Rolletto, so there's real reputational weight behind getting it right. That's a stronger position than a single-brand casino with nothing else at stake.
As with any Curaçao-licensed casino, the UK protections — affordability checks, deposit limits, the national self-exclusion scheme — don't apply, and disputes run through Curaçao's framework rather than a UK regulator. Verify the current licence via our how to verify a Curaçao gaming licence guide if you want to check it yourself before depositing.
Donbet Pros and Cons
Donbet is a solid entry-level member of a strong family, and being clear about both sides is more useful than a sales pitch.
Pros:
- Part of the established Santeda group alongside higher-rated siblings — a real, verifiable network.
- Curaçao-licensed with an operator that has multiple brand reputations at stake.
- A clean, simple welcome offer rather than a complex multi-tier chase.
Cons:
- A modest €750 bonus cap — the smallest in its own family.
- Curaçao licensing means fewer protections than a UK-licensed casino.
- Its bigger siblings (Cosmobet, Velobet) simply offer more, so Donbet is rarely the top pick within its own group.
Best Alternatives to Donbet
If you want to spread your play across separate operators rather than keep it all inside one company, the two options below run on a different operator group from Santeda — useful diversification if you'd rather not have every account under one roof. This is about spreading risk across operators, not about a different licence. 18+, terms apply.
HadesBet review — an independent operator with up to €5,000 plus 300 free spins at 35x wagering, and a 4,000+ game library. A genuinely separate operator group from Santeda, so it diversifies where your accounts sit.
Betmac review — a separate operator running a genuine sportsbook with Bet Builder and cash-out on a 3,000+ game library. The pick if you want casino and sport on one account, outside the Santeda family.
Worth noting separately: Zizobet is another strong Curaçao casino with an 800% package up to €7,800 plus 1,000 free spins and 25% cashback. Its Santeda membership is disputed across sources, so we don't list it as a confirmed Donbet sister — but it's a powerful option in its own right if you're comparing big Curaçao welcomes.
How Donbet and Its Family Compare
| Casino | Operator | Welcome (headline) | Cashback | Best for |
|---|---|---|---|---|
| Donbet | Santeda | 150% up to €750 + 50 FS | — | Simple entry-level welcome |
| Cosmobet | Santeda | 750% up to €7,000 + 1,000 FS | 15% | Highest-rated of the family |
| Velobet | Santeda | 700% up to €7,500 + 1,000 FS | 25% | Largest cap in the family |
| Rolletto | Santeda | 330% up to €3,000 + 50 FS | — | Smaller, simpler package |
| HadesBet | Independent | Up to €5,000 + 300 FS, 35x | — | Diversifying off-network |
The pattern is clear: within the Santeda family, Cosmobet and Velobet outclass Donbet on bonus size, and Cosmobet leads on rating — so if you came for Donbet, its own sisters are often the better call. For spreading across a separate operator, HadesBet and Betmac are the off-network options.
Final Verdict — Donbet and Its Sister Sites
Donbet is a legitimate, Curaçao-licensed casino in a genuinely strong family — but it's the entry-level member of that family, and its bigger siblings usually offer more. The best "Donbet sister site" for most players is Cosmobet, our top-rated of the group. Donbet itself is a fine starting point; it's rarely the finishing one.
If you like the Santeda style and want the strongest brand in the family, Cosmobet is the lead pick, with Velobet close behind for the largest cap and Rolletto for a simpler offer. If you'd rather spread your accounts across separate operators, HadesBet and Betmac are the off-network diversification options — and Zizobet is a strong standalone Curaçao welcome if you're weighing the biggest packages.

Casinos outside the UK framework run their own limit and self-exclusion tools, and those work on that site only. A self-exclusion you register in the UK won't restrict access to a casino like Donbet, and because the Santeda brands share an operator, excluding at one doesn't reliably cover the rest. If you need controls that hold everywhere, device-level blocking software is the tool that actually does it.
