Cosmobet Sister Sites: 7 Brands, Only 3 Real (2026)

Cosmobet sister sites are Rolletto, Goldenbet, Velobet, MyStake, Donbet, Freshbet and Jack.com. Only Rolletto, Goldenbet and Velobet sit with the same company as Cosmobet. Goldenbet has the best terms of the eight. Cosmobet itself publishes less about its own games and terms than any brand in the group, which is the first thing worth knowing about it.

All Cosmobet sister sites compared

Eight brands, three companies. Most guides to this network still describe it as one family under one roof, and that stopped being true during 2026.

18+. T&Cs apply. If gambling is causing you problems, GamCare and the National Gambling Helpline on 0808 8020 133 can help.

“Moved to a different company in 2026” is the row that matters when something goes wrong. A complaint at MyStake is a complaint against a different legal entity from the one holding your Cosmobet balance, even though the two sites run on the same software. Our MyStake page sets out that split from the other side.

What Cosmobet does not tell you

This is the part that separates Cosmobet from its siblings, and it is worth being blunt about.

Cosmobet’s pages serve almost no readable content without JavaScript, and its help and terms sections sit behind the app rather than on a public page. Read from a British connection on 15 August 2026, the site returns a working page with no game count, no wagering figure, no withdrawal limit and no company name in the footer text.

Its own homepage banner does advertise a welcome offer: 150% up to £500 plus 50 free spins. The conditions attached to it, the wagering multiple, the maximum bet and the expiry, are not published alongside it.

That matters more than it sounds. Every sibling on this page states a wagering multiple somewhere a reader can find it. Cosmobet states a headline and stops.

Who actually runs Cosmobet

Most guides to this network, including earlier versions of our own pages, record Cosmobet’s operator as unknown. It is not.

The Curaçao Gaming Authority publishes a certificate for cosmobet.com through its own portal, reached from the seal in the site’s footer. That certificate names Santeda International B.V. as the operator, under the same Curaçao licence that covers Rolletto, Goldenbet and Velobet.

So Cosmobet is not an orphan brand that merely resembles the others. It is on the same account as three of them, and a dispute at Cosmobet is a dispute with the same company you would be dealing with at Rolletto.

The best Cosmobet sister sites

Three are worth naming ahead of Cosmobet itself, because all three publish terms it does not.

Goldenbet: best bonus terms. Its bonus winnings are capped at 10x, double Velobet’s 5x, and it is the only genuinely player-favourable term in this group. 7,000+ games from 80+ providers, £20 minimum, 35x on slots inside 30 days. Same company as Cosmobet, so switching changes the terms without changing who holds your money.

Jack.com: best wagering terms by a distance. Its 100 welcome spins carry no wagering on the winnings at all, where the rest of this group asks 30x to 40x. It sits on a third company, so it is a change of counterparty as well as of terms.

Donbet: biggest library. Its lobby counter reads 8,778 games from 91 named providers, the largest published figure here. The offer is 150% up to €750 plus 50 spins, with 30x applied to deposit, bonus and spin winnings together. Our Donbet page goes through those terms line by line.

Rolletto is the pick on reputation rather than terms: the longest-trading brand of the group, with a Casino Guru Safety Index of 8.5 out of 10 as of 2026, and the highest wagering of the eight at 40x. Our Rolletto page sets out that trade-off, and our Velobet page covers the brand with the biggest headline and the tightest ceiling.

What carries over, and what doesn’t

Almost nothing carries over between Cosmobet sister sites, and the one thing that does is the thing most people assume is separate.

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

If the idea of one company running several near-identical brands is new to you, what sister sites are covers the pattern before you act on any of it.

Cosmobet sister sites no deposit bonus

None of the eight publishes a no-deposit bonus on the pages that load from Britain. Every welcome offer here needs a deposit first, and Cosmobet does not state its own minimum.

Jack.com is the closest thing to what people are looking for when they search this. Its 100 spins carry no wagering on the winnings, so what you win from them is withdrawable rather than locked behind a multiple. That beats most no-deposit offers, which usually carry the heaviest wagering on a site.

Treat any third-party page offering a Cosmobet no-deposit code with suspicion. Codes for this group circulate widely and expire quietly, and an expired code is the commonest reason a bonus never appears.

Bonuses and wagering across the group

The wagering across this group runs three to four times what British rules allow. Since 19 January 2026 those rules cap bonus wagering at 10x. Velobet, MyStake and Donbet apply 30x, Goldenbet 35x, and Rolletto 40x on its first two deposits. Cosmobet does not publish a figure.

The multiple is only half of it. Velobet, MyStake and Donbet apply their 30x to deposit plus bonus rather than the bonus alone, which roughly doubles the turnover for the same headline number.

Work it through on the group’s commonest shape. A £100 deposit at 150% becomes £250, and 30x on deposit plus bonus is £7,500 of turnover before a withdrawal. How wagering requirements work sets out the arithmetic if you want to run it on a different figure.

An unpublished multiple should be read as at least as demanding as its siblings, not as an absence of one. Nothing in this group waives wagering except Jack.com’s welcome spins.

Deposits, withdrawals and how long you wait

Six of those rows are blank because Cosmobet leaves them blank, not because the figures are hard to find. Where a sibling on the same platform publishes a number, it is given above as the group reference, and it should not be assumed to bind Cosmobet.

Are they actually different?

No. The machinery underneath is one system, and the differences that are real are narrow.

Cosmobet, Rolletto and Velobet load the same front-end application. The three sites share a footer template, the same lobby code and the same per-brand identifier pattern, with only the identifier changing between them. Two of them open side by side would show you the same cashier, the same slot grid and the same verification queue.

What genuinely differs across the Cosmobet sister sites is worth listing plainly. Donbet’s counter reads 8,778 against Goldenbet’s 7,000+ and Velobet’s 5,000+. Goldenbet caps bonus winnings at 10x where Velobet caps at 5x. Rolletto’s 40x wagering is the worst of the eight, and Jack.com’s no-wagering spins are the best single term in the group.

Everything else, the cosmic theming and the premium wrapper and the sportier everyday version, is styling.

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

Complaints and what players say

Casino Guru rates MyStake’s Safety Index 9.7 out of 10 and Rolletto’s 8.5 out of 10 as of 2026. Cosmobet carries a thinner public record than either, which is what you would expect of the brand in this family that publishes least about itself.

The complaint patterns across this group are the ordinary offshore ones: identity checks requested at withdrawal rather than at signup, bonus terms applied more strictly than players expected, and ceilings slowing large payouts. None of that is unique to these brands.

A thin record is not the same as a clean one. With no published wagering figure to hold Cosmobet to, a dispute about how a bonus was applied starts from a worse position than the same dispute at Goldenbet, where the terms are on the page.

Drawbacks and gaps

Cosmobet is not licensed in Britain, and neither is any brand on this page. That has three consequences worth being clear about.

British dispute routes do not apply. If a complaint is not resolved, there is no independent adjudicator to escalate to and no deposit protection standard the operator has to meet.

The terms you would be agreeing to are not published before you register. That is the specific gap at Cosmobet, and it is the reason to prefer a sibling that states its numbers.

Shared failure is real. The June 2025 outage took seven brands down together for about 20 hours. Spreading play across these Cosmobet sister sites does not spread the risk, because the platform underneath is the same one.

An offshore brand can also close a market with no notice. NineWin now turns British visitors away entirely, having previously accepted them, and the same could happen to any brand here.

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

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

Excluding yourself at Cosmobet does not block Rolletto, Goldenbet, Velobet, MyStake, Donbet, Freshbet or Jack.com. Each takes a separate registration, and the exclusion does not travel across the group despite the shared platform. Since the brands were divided between three companies during 2026, an exclusion does not even travel between all the sites run by one company.

GAMSTOP does not cover any of them. GAMSTOP blocks you across every operator licensed in Britain, and none of these eight is. If you are relying on a GAMSTOP registration to keep you away from gambling sites, it will not stop you opening an account at any brand on this page.

If that matters to you, the practical step is a device-level blocker such as GamBan, which works whatever a site is licensed under, together with GAMSTOP for the British market. Free, confidential support is available from GamCare and the National Gambling Helpline on 0808 8020 133.

Which Cosmobet sister site should you pick?

Goldenbet, on the evidence available. It runs on the same platform and the same company as Cosmobet, and it publishes the things Cosmobet does not: a 35x multiple, a £20 minimum, a £5 maximum bet, a 30-day clock and a 10x cap on bonus winnings. Every one of those is a term you can hold it to.

Jack.com, if the wagering is your objection. No wagering on the winnings from 100 spins is the best term here, and nothing else comes close.

Cosmobet itself is hard to recommend over its own siblings, and the reason is not its games or its offer. It is that you cannot read the terms before you deposit, and three brands on the same software will show them to you.

If none of the Cosmobet sister sites appeals, a British-licensed brand gives you an adjudicator and a 10x wagering cap that no brand on this page can offer. MrQ is one such alternative, and its network is a fraction of the size.

Who runs these sites

Cosmobet, Rolletto, Goldenbet and Velobet are operated by Santeda International B.V. under Curaçao licence OGL/2024/1798/1048. MyStake and Donbet moved onto GTW B.V. during 2026, and Freshbet and Jack.com run under Ryker B.V., a third company registered in Curaçao.

Cosmobet’s footer carries a certificate seal linking to the Curaçao Gaming Authority’s own portal. That certificate names Santeda International B.V. as the operator of cosmobet.com and states the current status as “Active”.

The same authority’s licence registry for 6 August 2026 records that term as having run out on 24 December 2025, with a status of “Assessment in progress”. Two documents from one authority, and only the register dates itself. That status applies to 301 holders on the same document, so it describes a transition queue rather than a finding against one company.

Ryker, by contrast, shows no expiry date and a status of “Indefinite”. None of the three companies appears on the authority’s separate enforcement register of revoked and suspended holders, dated 10 July 2026.

None of the eight brands appears on Britain’s public register. Data for 3 August 2026 returns nothing for Santeda, Cosmobet, Rolletto, Goldenbet, Velobet, MyStake, Donbet or Freshbet against any account, trading name or domain. You can search it yourself at the Gambling Commission’s public register.
