Donbet Sister Sites: 6 Brands, Only 1 Real (2026)

Donbet sister sites come down to one sibling: MyStake. Both sites are run by the same Curaçao company. Goldenbet, Rolletto, Velobet and Cosmobet were stablemates until the group split its brands between two companies, and those four now sit on a different one. Donbet’s own lobby counts 8,778 games, the largest figure in the family.

All Donbet sister sites compared

These brands divide along a line most listings miss. Two rows share Donbet’s operator. The four below them share its history and its platform, but not the company that holds your money.

“Former stablemate on a different company” is the row that matters if something goes wrong. Donbet and MyStake are operated by one Curaçao company; Goldenbet, Rolletto and Velobet are operated by another.

A dispute at Goldenbet is therefore a dispute with a different legal entity from the one holding your Donbet balance, even though the two sites look and behave almost identically. We cover the other half of the family on our MyStake network page.

Three things repeat across every brand here and so are not worth a column. Minimum deposit is €20 or £20 wherever it is published. Maximum bet while a bonus is live is €5 or £5 throughout. Every offer is slots-only with a 30-day clock.

Wagering is where the spread is real: 30x at Donbet, MyStake and Velobet, 35x at Goldenbet, and 40x on Rolletto’s first two deposits, the worst term of the six.

Why the Donbet sister sites list is shorter than it looks

Almost every guide to this network still describes six brands under one company. That was the picture until the group moved brands onto a second Curaçao account during 2026.

Donbet’s own site names GTW B.V. as its operator. So does MyStake’s. Goldenbet, Rolletto and Velobet name Santeda International B.V. Both companies are registered in Curaçao and the sites still share a platform, so the family resemblance is real, but the corporate line now runs between MyStake and Goldenbet rather than around all six.

Trade coverage in February 2026 reported the move and tied it to regulatory and press attention on the network’s UK-facing activity. Jordan Lea, chief executive of the gambling-harm research group GAMRS, described the manoeuvre as “a common tactic in the black market ecosystem”, adding that “when regulatory pressure or consumer redress becomes a problem, providers simply wipe the slate clean”.

Freshbet and Jack.com are sometimes listed alongside these brands too. They belong to a third Curaçao company again, and have never sat on either of the accounts above. If you are working out what counts as a sibling in the first place, our guide to sister sites sets out what a shared operator does and does not mean for you.

The best Donbet sister sites

Three picks, each for one checkable reason. There are only two brands on Donbet’s own account, so the third looks outside it.

MyStake: the only true sibling. It is the one brand run by the same company as Donbet, so it is the only site here where the group’s own structure connects your two accounts. Casino Guru rates its Safety Index 9.7 out of 10, the highest of the six, against a 300% package up to €1,500 spread across three deposits at 30x on deposit plus bonus.

Goldenbet: best bonus terms. Its 10x cap on bonus winnings is double Velobet’s 5x, and unlike Donbet it states a ceiling at all, which is the most player-favourable term anywhere in this family. 7,000+ games from 80+ providers, £20 minimum, 35x wagering on slots only inside 30 days. The trade-off is that it now sits with a different company from Donbet.

Rolletto: best reputation. The longest-trading brand of the group, with a Casino Guru Safety Index of 8.5 out of 10 as of 2026 and the deepest complaint-resolution record. The cost is the wagering: 40x on the first two deposits, the highest here.

Donbet itself is the pick on library size alone. The bonus terms below show why the largest lobby of the six is not the same thing as the best deal of the six.

What carries over, and what doesn’t

The platform row explains most of what follows. A shared cashier means shared withdrawal behaviour, shared identity-check demands and shared outage risk, which is what happened in June 2025.

Donbet sister sites no deposit bonus

None of these brands runs a no-deposit welcome offer. Every published welcome offer across the six requires a qualifying deposit of €20 or £20.

Donbet does run wager-free rewards once you are playing: free spins, cash and free bets claimed through its loyalty ranks carry no wagering, and its terms state that weekly cashback becomes wager-free from rank six. Those are loyalty mechanics for funded accounts, not a way in without depositing.

If a genuine no-deposit offer is what you came for, this family is not where it lives.

Bonuses and wagering across the group

The wagering across the Donbet sister sites runs three to four times what UK rules allow. Since 19 January 2026, those rules cap bonus wagering at 10x. Donbet, MyStake and Velobet apply 30x, Goldenbet 35x, and Rolletto 40x on its first two deposits.

The multiple is only half of it. Donbet applies its 30x to deposit plus bonus plus any winnings from the free spins, which is a wider base than the bonus alone and roughly doubles the turnover for the same headline number. Our guide to how wagering requirements work sets out why that distinction costs more than the multiple does.

Work Donbet’s own offer through. Deposit €500, the point at which the offer stops scaling, and the bonus is €750. Wagering at 30x on €1,250 is €37,500 of turnover inside 30 days at a €5 ceiling on any single bet.

What that turnover can return is the part Donbet does not state. Its general terms cap withdrawals from a wagering bonus at five times the bonus, then exempt welcome bonuses from that rule in the same sentence. The largest offer on the site is therefore the one with no published ceiling, and you cannot work out your maximum before you deposit.

Goldenbet is the cleaner structure of the family. 35x applied to a £500 bonus alone is £17,500 to turn over, and its published 10x cap lets the same bonus return up to £5,000. Higher multiple, better arithmetic, because the wagering does not touch your deposit and the ceiling is one you can read in advance.

Donbet also splits its welcome offer by product rather than running one. The casino match above is 150% up to €750; depositing in cryptocurrency instead moves you to 170% up to €1,000 with 100 spins, and the sport and mini-games versions pay 120% and 100% up to €600. You take one of them, not several.

Every casino offer above is slots-only and expires in 30 days, with a €5 or £5 cap on any single bet while a bonus is live.

Deposits, withdrawals and how long you wait at Donbet

The 20% clause is the one to read twice. Depositing and then asking for the money back without playing it through once is treated as a chargeable event, not a refund.

The instalment wording matters as much as any headline number. Where there is no published ceiling, the ceiling is whatever the payment method imposes, and a large win leaves in pieces over an unstated period, with no British body to escalate to if those pieces stop arriving.

Are they actually different?

Mostly no. The Donbet sister sites share a platform, a cashier, a support layer and a game library drawn from the same suppliers. Lobby artwork and promotional rate cards are where they differ; the machinery underneath is one system, which is why splitting them between two companies changed the paperwork rather than the product.

The differences that are real and checkable are narrow. Donbet’s lobby counter reads 8,778 against Goldenbet’s published 7,000+ and Velobet’s 5,000+. Goldenbet caps bonus winnings at 10x and Velobet at 5x, where Donbet’s welcome terms publish no ceiling at all. Rolletto’s 40x wagering is the worst of the six, and its Casino Guru score of 8.5 is the best-established.

The June 2025 outage made the shared spine visible. On the evening of Sunday 14 June 2025, Donbet, MyStake, Goldenbet, Rolletto, Velobet, Cosmobet and Freshbet all went dark for roughly 20 hours after game suppliers pulled content from operators serving UK customers without British authorisation. The sites returned with smaller game libraries.

Spreading your play across these brands does not spread that risk. It is one platform wearing six sets of colours.

Complaints and what players say

Casino Guru’s Safety Index for Donbet is given as 8.4 out of 10 on one listing and 8.6 on another, so the score is high but the listings do not agree on it. Both describe its terms as mostly fair and record no significant blacklist entries.

Trustpilot is harder to read, because several Donbet profiles exist under different domains and they disagree. A donbet.win profile shows 4.1 out of 5 from around 138 reviewers, a donbet.io profile 3.8 from around 20, and a donbet-uk.com profile 3.7. Donbet’s own pages name donbet.com, donbet.net and donbet.win as its addresses, so the profiles attached to other domains may not describe the same operation at all.

The complaint themes that recur across the Donbet sister sites are specific: withdrawals held at identity checks, and money that cannot be returned to the card it came from.

The €5 maximum bet rule deserves attention because of how the terms treat a breach. Donbet’s own conditions state that spins staked above €5 are excluded from the wagering requirement and that winnings from them are forfeited. Placing one bet above the cap while a bonus is live is the most common route to a lost balance across offshore groups.

Complete identity checks in your first session rather than at cashout. It removes the most common cause of a held payout.

Drawbacks and gaps

No British oversight. There is no UK dispute route across any of these brands, no deposit or stake limits, no affordability checks, and no independent adjudicator such as IBAS to take a complaint to. Our guide to what British oversight actually protects covers what that absence costs you, and the same gap applies to DaytonaSpin, which we reviewed separately.

Wagering three to four times the British ceiling, and applied at Donbet to deposit, bonus and spin winnings together rather than to the bonus alone.

No published ceiling on the welcome bonus. Donbet’s terms cap other wagering bonuses at five times the bonus and then exempt welcome bonuses, so the biggest offer on the site is the one whose maximum return it does not state. Goldenbet and Velobet both publish theirs.

No published withdrawal ceiling either. The maximum depends on the payment method, and a limit you cannot read before depositing is a limit you discover at cashout.

Shared failure. The June 2025 outage took seven brands down together for about 20 hours.

Published scrutiny. A Guardian and Investigate Europe investigation in April 2026 described this network as accessible to UK players without British authorisation, and reporting in early 2026 put UK-facing turnover at around £1.2bn with MyStake during 2025 and £3.51bn across the wider network. A December 2025 report by GAMRS reached similar conclusions. All are third-party estimates and worth reading before you decide anything.

If you self-excluded on one, are you blocked on the rest?

No, and this is the single most important thing on this page.

Excluding yourself at Donbet does not block MyStake, Goldenbet, Rolletto, Velobet or Cosmobet. Each of the Donbet sister sites takes a separate registration, and the exclusion does not travel across the family despite the shared platform. Since Donbet and MyStake moved onto one company and the other three onto another, an exclusion now has even less reason to carry.

Donbet’s own process is worth knowing before you rely on it. Self-exclusion is requested by emailing support rather than through a switch in your account, runs for a period between six months and five years, and defaults to six months if you do not name one.

A shorter time-out can be lifted early, and its terms state that reopening is at the casino’s sole discretion. A British-licensed site cannot reverse a self-exclusion on request in that way.

GAMSTOP does not cover any brand on this page. GAMSTOP applies only to operators licensed in Great Britain, and none of these are. If you have registered with GAMSTOP, that registration blocks British sites and leaves these reachable. The protection you signed up for has a hole in it here, not a door. Queen Vegas and its network do the opposite: one request covers all 52 brands on the account.

That gap is the reason to treat a self-exclusion decision as needing more than one operator’s cooperation. Tools that work regardless of where a site is licensed:

• Device and network blocking software, which stops the sites loading at all rather than relying on the operator to turn you away.
• Bank-level gambling blocks, offered by most UK banks, which decline gambling transactions at the card level.
• GamCare and the National Gambling Helpline on 0808 8020 133, free and 24 hours a day, who can set both of those up with you. Our responsible gambling page collects them in one place.

GAMSTOP remains worth registering for even so, because it covers every British-licensed site in one action. It is a floor, not a ceiling.

If you excluded at one of these brands and are reading this page looking for the others, the helpline number above is the more useful thing on it.

Which Donbet sister site should you pick?

MyStake, if you want the one that is genuinely Donbet’s sibling, and Goldenbet if you want the better terms and do not mind that it is now a different company.

Of the Donbet sister sites, Goldenbet wins on the one term that decides what a bonus can ever return: it publishes a 10x ceiling, so a £500 bonus can pay back up to £5,000. Donbet’s welcome terms publish no such figure. Donbet keeps the largest library at 8,778 games, which matters less than a stated ceiling does once you are trying to withdraw.

The honest wider answer is that a British-licensed site gives you a 10x wagering ceiling, enforced deposit limits, an independent complaints route and GAMSTOP coverage, none of which any brand on this page provides.

Who runs these sites

Donbet and MyStake are operated by GTW B.V. under OGL/2024/250/0115, company number 165433, shown as active on the Curaçao Gaming Authority’s certificate for donbet.com on 8 August 2026. Goldenbet, Rolletto and Velobet are operated by Santeda International B.V. under OGL/2024/1798/1048, company number 151296, the company that held all six brands before the split.

The certificate is not the whole picture, and it sets the same trap as NineWin’s. The authority’s own registry for 6 August 2026 lists both companies against a term that ran out on 24 December 2025, with a status of “Assessment in progress” rather than an active one.

That status covers 301 of the holders on that document, so it describes a transition queue rather than a finding against either company. It is still the point: the badge on a site’s footer and the line on the register answer different questions, and only one of them tells you whether the term is current.

Neither company appears on the Gambling Commission’s register. Its data for 3 August 2026 returns nothing for either company, or for Donbet, MyStake, Goldenbet, Rolletto, Velobet or Cosmobet, against any account, trading name or domain. You can search it yourself at its public register.

A Curaçao brand can also close a market overnight. NineWin, run by a different Curaçao company, now turns British connections away at its own front door, and our NineWin review covers what that looks like and when its certificate runs out.

Gambling should be entertainment, never a way to make money. If it has stopped feeling that way, GamCare and the National Gambling Helpline on 0808 8020 133 can help.
