Donbet sister sites

Which brands share Donbet's operator, licence and platform, what its 150% slot welcome asks of you, and how the sister sites' welcome terms compare.

The short answer
  • MyStake shares Donbet's operator, GTW B.V., and its Curaçao licence OGL/2024/250/0115. Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet share the platform under Santeda International B.V.
  • Donbet's slot welcome is 150% up to €750 plus 50 free spins, at 30x the deposit, bonus and spin winnings within 30 days.
  • MyStake extends the same first-deposit match over 3 deposits, and none of the 7 brands holds a Gambling Commission licence.

Donbet's footer names GTW B.V. and its Curaçao licence, and MyStake carries the same operator text and licence number. 5 more brands, Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet, run on the same platform under a related company, Santeda International B.V., so we compare them separately. This page is for a player who already knows Donbet and wants to know which brands sit around it and whether the differences are worth acting on. The short answer is that the lobby and cashier barely differ, so the real reasons to switch are welcome structure, the time allowed to clear wagering and what each brand does with an account you stop using.

The Gambling Commission requires any operator offering remote gambling to consumers in Great Britain to hold a Commission licence, including operators based overseas. None of the 7 brands on this page holds one, so none is authorised to serve players in Great Britain.

A note on money: welcome offers and minimum deposits display in euros, the base currency these brands use, with dollar figures alongside. Treat the euro figure as the published offer rather than a converted sterling amount, because the figure that applies follows your account's registered currency.

Which Donbet sister site fits which player

The table starts with what each brand does differently from Donbet and the restriction to check before signing up. Welcome offers sit in a separate table further down, because the wagering deadlines covered below decide how much they are worth.

What existing Donbet players need to know

Two points matter more to a Donbet player than any welcome figure: how the bonus rules follow you from one site to the next, and how accounts, verification and idle balances are treated.

Welcome bonus eligibility

Donbet's terms allow no more than one of each bonus per user, IP address, device, family, residential address, telephone number, card, payment account and email address, and only one account per person, household or IP address. MyStake, Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet use the same wording. We could not establish whether the brands share customer data with each other, so do not assume a second welcome will be honoured, and do not assume it will be refused.

If you have already taken Donbet's welcome, the recurring terms are the better comparison. Donbet's promotions list a 10% loyalty cashback, which we could not read in full. MyStake's loyalty cashback is 10% on request, capped at €500 at a time, at 45x with a 5x withdrawal cap, and Goldenbet's runs on almost the same terms. MyStake also pays 10% of monthly crypto losses without wagering, and Velobet advertises a 10% VIP cashback without wagering. Those terms outlast any sign-up offer.

Accounts, verification and withdrawals

Each brand is a separate site with its own registration, balance and identity checks. There is no shared login, and balances are not pooled across brands. Donbet's terms let it check identity before processing payouts and hold withdrawals while it does, and they cap withdrawals at €7,500 a week and €15,000 a month.

We could not establish whether documents accepted at one brand are recognised at another, so treat each site as a fresh verification. A common complaint pattern across offshore casinos is a first withdrawal held until documents are supplied, which is avoidable if verification is finished first. The inactivity terms differ more than most readers expect. Donbet treats an account as dormant after 12 months without a login and can then charge €10 a month, and MyStake and Goldenbet use the same clause. Rolletto starts after 60 days and charges 20% of the balance a month, Cosmobet starts after 365 days at 5% a month capped at €20, and we found no dormancy clause in the Velobet and Zizobet terms we read.

How the sister sites compare

Wagering is the term to read closely, because at every brand that publishes it here it attaches to deposit plus bonus rather than the bonus alone. A £100 deposit plus a £100 bonus at 30x deposit-and-bonus wagering requires £6,000 in qualifying bets before withdrawal, not £3,000. That is arithmetic on the stated terms, not a live offer.

Donbet's own slot welcome is a 150% match on a first deposit of €20 to €500, so up to €750, plus 50 free spins, on slots only. Its wagering is 30x the deposit, the bonus and any free-spin winnings, to be completed within 30 days with a €5 maximum bet. A €100 deposit earns a €150 bonus and needs €7,500 in bets plus 30 times whatever the spins win. Its promotions also list a 120% sports welcome up to €600 and a 170% crypto welcome with 100 free spins, whose terms we could not read.

MyStake

MyStake is Donbet's closest relative: the same company, GTW B.V., and the same licence, OGL/2024/250/0115. Its casino welcome is a 300% package up to €1,500 across the first 3 deposits: 150% up to €750, 100% up to €500 and 50% up to €250, on slots only at 30x deposit plus bonus within 30 days. The minimum deposit is €20 and the maximum bet €5.

MyStake homepage
MyStake's homepage (mystake.win), September 2026.

The first deposit matches Donbet's exactly, at 150% up to €750, and MyStake then adds 2 more deposit bonuses where Donbet stops. Its crypto cashback is the other difference: 10% of monthly net losses on crypto deposits, credited without wagering. MyStake's general terms carry no 10x-deposit clause, and neither do Donbet's.

For a Donbet player who wants the same licence holder and a longer welcome, MyStake is the closest thing to a safe default in the group. A sports-only player gains little over Donbet here.

Velobet

Velobet's casino welcome covers 3 deposits: 150% on a first deposit of €10 to €500, or 100% on €500 to €1,000, plus 300 free spins, then 100% up to €500 and 80% up to €500. All 3 parts carry 30x deposit-plus-bonus wagering within 30 days with a €5 maximum bet, and the minimum deposit is €10.

Velobet homepage
Velobet's homepage, September 2026.

The free spins and the entry point are the differences. Velobet adds 300 spins to a first-deposit match the same size as Donbet's, and it accepts deposits from €10 rather than €20. Its general terms cap the amount withdrawable from deposit-bonus winnings at 10 times the qualifying deposit, a clause we did not find in Donbet's terms.

For a Donbet player who deposits small amounts and wants spins with the match, Velobet is the strongest fit in the group. A player who expects to win far above their deposit should read the 10x cap first.

Goldenbet

Goldenbet listed no casino welcome on its promotions page when we checked in October 2026. Its recurring offers are 100 wager-free spins on Thursdays and Fridays for a €50 deposit with a promo code, and a 10% cashback on request. The minimum deposit is €20.

The cashback can be requested any number of times a day, but each payment is capped at €500, carries 45x wagering within 15 days and allows withdrawals of no more than 5 times the cashback. For sport it returns 20% of a losing accumulator as a free bet, up to €500 per bet, and adds a €20 free bet on Saturdays, the closest match to Donbet's sports focus among the Santeda brands.

For a Donbet player who bets on sport every week and has used up the welcome, Goldenbet earns its place. A player looking for a sign-up offer gains nothing here.

Cosmobet

Cosmobet spreads its welcome over the first 4 deposits, each a 100% match up to €500, for up to 400% and €2,000 in bonus. Each part carries 30x deposit plus bonus on slots only, with a €5 maximum bet, and must be cleared within 7 days of activation. The minimum deposit is €20.

Cosmobet homepage with its space theme
Cosmobet's homepage, September 2026.

The free spins depend on deposit size rather than the match. Each deposit of €20 to €99.99 adds 50 spins, €100 to €199.99 adds 100, and €200 or more adds 250, so the 1,000 in the headline needs 4 deposits of at least €200. Cosmobet's dormancy terms are the mildest in the group, at 5% a month capped at €20 after a full year without a login.

For a Donbet player who deposits €200 or more at a time and plays daily, Cosmobet is worth its place. A player who cannot meet a 7-day deadline gains nothing over Donbet's 30 days here.

Zizobet

Zizobet has the highest headline rate in the group: 550% up to €5,300 with up to 900 free spins across 4 deposits, and a crypto alternative of 630% up to €6,060 with 1,000 free spins. The first 2 deposits earn 100% and 110% on €10 to €500 and 150% on €500 to €1,000, the third earns 100% up to €800, and the fourth qualifies only from €500. The minimum deposit is €10.

Zizobet homepage with its welcome offers
Zizobet's homepage, September 2026.

The terms published with the welcome in October 2026 set 30x wagering on deposit plus bonus within 5 days of activation. On a €100 first deposit Zizobet pays 100% where Donbet pays 150%, so the headline only overtakes Donbet on deposits of €500 or more, and with a sixth of the time to clear it.

For a Donbet player who deposits €500 or more at a time and clears wagering quickly, Zizobet has the strongest headline. A player who deposits in the low hundreds is better served by Donbet's own match.

Rolletto

Rolletto carries the largest match cap in the group. Its welcome reaches up to €5,500 across 3 deposits: 150% up to €500, 50% up to €2,000 and 25% up to €3,000, with 50 free spins on the first deposit and 30 more on each of the next 5 days of logins. The minimum deposit is €20.

Rolletto homepage
Rolletto's homepage, September 2026.

The cap comes at the price of the hardest terms in the group. The first 2 parts carry 40x deposit plus bonus and the third 30x, each within 5 days, and reaching the second and third caps takes deposits of €4,000 and €12,000. Its inactivity clause is the strictest in the group, at 20% of the balance a month after 60 days. It also runs a sports welcome of 150% up to €1,500 at 15x within 15 days.

For a high-volume player who can clear heavy wagering quickly, Rolletto has the strongest cash headline. A Donbet player who leaves money in an account between sessions should not do so here.

Welcome offers and payment terms

The table separates 2 limits that constrain different things: the bonus win cap, which limits what a bonus can pay out, and the monthly ceiling, which limits total cash-out from the account. Where a figure was not in the terms we read, the table says so rather than implying a check that did not happen.

What you keep when you switch, and what changes

All 7 brands share the same lobby structure, the same crypto-forward cashier, the same €7,500 weekly and €15,000 monthly withdrawal limits, the same one-bonus-per-household rule and identity checks that can be triggered at any time. Affiliate material that presents them as 7 separate casinos is describing one product in several colours. Donbet and MyStake also share an operator and a licence; the other 5 sit under Santeda.

The differences that remain are short. MyStake extends Donbet's welcome to 3 deposits. Velobet adds 300 spins. Goldenbet pays cashback instead of a welcome. Cosmobet pays spins by deposit size. Zizobet pays more on large deposits. Rolletto has the biggest cap and the hardest wagering. Nothing else is shared: each brand has its own registration, balance, verification, inactivity clock and self-exclusion.

Donbet's footer names GTW B.V., Curaçao company number 165433, registered at Zuikertuintjeweg Z/N, and licence OGL/2024/250/0115 from the Curaçao Gaming Authority, with CYGTW LTD of Limassol, Cyprus, as payment agent. MyStake's published footer text names the same company, number, licence and payment agent. The test a reader can run is the same: a site whose operator text names GTW B.V. and OGL/2024/250/0115 is on Donbet's licence. The test confirms a shared licence, so read it as strong evidence of a sister relationship, not absolute proof of one.

Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet appear on many Donbet sister-site lists, and all 5 fail that test, because their published operator text names Santeda International B.V., company number 151296, and licence OGL/2024/1798/1048. They belong in this comparison because of the platform and the reporting around it. In February 2026, NEXT.io and The Gaming Boardroom reported the group moving brands including Donbet, Goldenbet, Velobet and MyStake from Santeda to GTW on their footers, and in April 2026 an investigation by Investigate Europe and the Guardian linked at least 8 sites, including Goldenbet, Velobet and MyStake, to the same network.

Two caveats attach to both companies rather than to any single brand. As observed in the Curaçao Gaming Authority's licence registry edition of 21 September 2026, both licences showed an expiry date of 24 December 2025 and a status of assessment in progress, which applies to every brand on each licence. In April and May 2026, NEXT.io and the Curaçao Chronicle reported that GTW B.V. and Santeda International B.V. had been dissolved while the sites kept trading. Donbet's footer still named GTW in October 2026, which means a complaint may have no clearly identifiable company to answer it.

Risks, protections and self-exclusion

Outside the Gambling Commission's regime you lose the protections that come with it. These operators do not apply its deposit-limit and affordability rules, and they are not bound to its complaints and dispute-resolution process. GAMSTOP does not cover these sites, and we found nothing in the terms we reviewed that extends a self-exclusion from one brand to another, so treat each exclusion as applying only where you set it.

If you have self-excluded through GAMSTOP, these sites sit outside the protection you chose, and that exclusion exists for a reason. Free, confidential support is available from GamCare and the National Gambling Helpline on 0808 8020 133, run by GamCare, and GAMSTOP covers every site licensed in Great Britain.

If you do play, 2 steps prevent avoidable harm. Complete identity verification when you sign up, so a first withdrawal is not held for documents. Read the wagering basis, the bonus win cap and the €15,000 monthly limit before depositing money you would mind losing.

FAQ

Common questions

Who operates Donbet and its sister sites?

GTW B.V. operates Donbet and MyStake under Curaçao company number 165433 and licence OGL/2024/250/0115. Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet run on the same platform under Santeda International B.V. and licence OGL/2024/1798/1048.

How many Donbet sister sites are there?

1 shares Donbet's operator and licence: MyStake. We also compare Goldenbet, Velobet, Rolletto, Cosmobet and Zizobet, which share the platform under a related licence holder.

Can I claim a welcome bonus at more than one sister site?

Not reliably. Each brand limits its bonuses to one per household, IP address, device and payment method, and we could not establish whether the brands share that data with each other.

Are any Donbet sister sites licensed by the Gambling Commission?

No. Every brand holds a Curaçao licence only, and none holds the Commission licence required to serve players in Great Britain.

Does a Donbet self-exclusion cover the sister sites?

No. We found nothing in the terms that carries a self-exclusion from one brand to another, and GAMSTOP does not cover these sites.

Do I need a separate account for each sister site?

Yes. Each brand has its own registration, balance, identity checks and inactivity clock, with no shared login.

Which sister site has the largest welcome bonus?

Rolletto by cash value, with up to €5,500 at 40x and 30x deposit-plus-bonus wagering within 5 days, and Zizobet by percentage, with 550% up to €5,300 at 30x within 5 days. Both cap withdrawable winnings from a deposit bonus at 10 times the qualifying deposit.

Is Goldenbet a Donbet sister site?

In part. Goldenbet shares Donbet's platform and group, but its published operator text names Santeda International B.V. and a different licence, so a complaint about Goldenbet goes to a different company than one about Donbet.
