MyStake sister sites

MyStake shares its operator, GTW B.V., and its Curaçao licence with 1 other brand, Donbet, and shares the Upgaming platform and group ownership with 5 more: Velobet, Rolletto, Goldenbet, Cosmobet and Zizobet. Those 5 run under a different licence holder, Santeda International B.V. This page is written for a player who already knows MyStake and wants to know which brands sit around it and whether the differences are worth acting on. The short answer is that the game lobbies barely differ, so the real reasons to look elsewhere are bonus structure, recurring cashback and the terms that decide how much you can withdraw.

The Gambling Commission requires any operator offering remote gambling to consumers in Great Britain to hold a Commission licence, including overseas operators. 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 most minimum deposits display in euros, the base currency these brands use, and a few pages show £, € and $ side by side. 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 MyStake sister site fits which player

The table starts with the question that matters to a MyStake player: what each brand does differently, and the restriction to check before signing up. Welcome offers sit in a separate table further down, because the bonus rules covered in the next section decide how much they should weigh.

What existing MyStake players need to know

Two points matter more to a MyStake player than any welcome figure: who actually holds each brand's licence, and how the bonus and account rules follow you from one site to the next.

Welcome bonus eligibility

MyStake's terms allow no more than one of each bonus per user, IP address, device, family, residential address, telephone number, card, e-wallet and email address, and only one account per person, household or IP address. The 5 Santeda brands use the same wording for their own accounts, and Cosmobet repeats it inside its welcome terms. 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 used MyStake's welcome, the recurring terms are the better comparison. MyStake pays 10% crypto cashback each month with no stated maximum, Velobet offers 10% VIP cashback without wagering, and Goldenbet pays 10% cashback on request. 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. MyStake's terms let it request identity documents at any time and before paying out, so verify early rather than at your first withdrawal.

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 you supply documents, which is avoidable if you finish verification first.

How the sister sites compare

Wagering is the term to read closely, because at every brand 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.

For reference, MyStake's own 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. It applies to slots only, with a 30x deposit plus bonus requirement within 30 days, a €20 minimum deposit, and a €5 maximum bet. Its menu adds proprietary Originals, Mini Games and a Prediction Markets section marked as new.

Donbet

Donbet is the only brand that shares MyStake's operator and licence. Its footer and terms name GTW B.V., Curaçao company number 165433, and licence OGL/2024/250/0115, the same entity and reference as MyStake's company details. The operator's own mobile site titles its welcome as 150% up to €750. We could not establish its wagering, minimum deposit or withdrawal limits, because Donbet's site blocked our checks with a security challenge.

Donbet's homepage, September 2026.

Where MyStake leads with its casino lobby, Donbet opens its menu with the sportsbook. The shared licence is also the practical difference that matters: a complaint about Donbet and one about MyStake go to the same licence holder, which is not true of the 5 Santeda brands.

For a MyStake player who bets on sport more than slots, Donbet puts the same platform in a sports-first order. Read its bonus terms before depositing, because we can't.

Velobet

Velobet runs on the same platform under Santeda International B.V. rather than GTW. The 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 carry 30x deposit-plus-bonus wagering within 30 days, and the minimum deposit is €10.

Velobet's homepage, September 2026.

The recurring terms are its edge. Velobet advertises a 10% VIP cashback without wagering, calculated on deposits made since your last withdrawal or bonus, and a separate 160% crypto welcome up to €1,000 at 35x. The €10 entry is the lowest in the group alongside Zizobet.

For a MyStake player who wants cashback that pays as cash rather than bonus money, Velobet earns its place. A player who only wants MyStake's Originals gains nothing here.

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's homepage, September 2026.

The wagering is the price of that headline. The first 2 deposits carry 40x deposit plus bonus, and the third 30x, and all must be completed within 5 days of activation, the tightest deadline in the group. Its crypto welcome is 100% up to €1,000 plus 200 free spins across 8 coins: Bitcoin, Bitcoin Cash, Ethereum, Litecoin, XRP, Dash, Monero and Stellar.

For a high-volume crypto player who can clear heavy wagering quickly, Rolletto has the strongest headline. A casual player is better served by MyStake's 30x over 30 days.

Goldenbet

Goldenbet borrows its lobby and cashier from MyStake, and its promotions page listed no casino welcome when we checked in September 2026. It leans on recurring offers instead: 100 wager-free free spins on Thursdays and Fridays with a €50 deposit and a promo code, and a 20% sports cashback paid as a free bet. The minimum deposit is €20.

Goldenbet's homepage, September 2026.

The 10% casino cashback is the main reason to consider it. You can request it several times a day, but the published terms cap each cashback at €500 and limit withdrawals to 5 times the cashback amount. It also requires €100 in deposits since your last bonus or withdrawal, counted over the last 7 days.

For a regular player who values frequent loss-back over a one-off sign-up match, Goldenbet is well worth it. A player who deposits once and rarely returns will not see the benefit.

Cosmobet

Cosmobet spreads its welcome over 4 deposits, each a 100% match up to €500 with up to 250 free spins. That totals up to 400% and 1,000 free spins, at 30x deposit plus bonus, from a £/€20 minimum deposit and with a €5 maximum bet.

Cosmobet's homepage, September 2026.

The deadline is the key detail. Each part must be wagered within 7 days of activation, against 30 days at MyStake. Cosmobet also runs a 200% crypto welcome up to €1,000 at 35x and a 10% monthly crypto cashback at 30x, and its welcome terms limit the package to one per player, household, IP address, email, address or device.

For a player who deposits in several smaller steps and plays often, Cosmobet stretches the welcome furthest. A slower player will struggle with the 7-day window.

Zizobet

Zizobet carries the biggest headline percentage. Its casino welcome is 550% up to €5,300 with up to 900 free spins across the first 4 deposits, and a crypto alternative reaches 630% up to €6,060 with 1,000 free spins. Its terms set a €10 minimum deposit.

Zizobet's homepage, September 2026.

Neither welcome states a wagering multiplier: the offer pages refer to the standard terms, which give none. Those terms cap withdrawable winnings from a deposit bonus at 10 times the deposit that activated it, and confirm the same €7,500 weekly and €15,000 monthly withdrawal limits as MyStake.

For a player chasing the largest multi-deposit package, Zizobet has the strongest headline. Read its welcome wagering before depositing, because that is where the headline is tested.

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

The same group runs all 7 brands on the same Upgaming platform, with the same lobby structure, crypto-forward cashier, €7,500 weekly and €15,000 monthly withdrawal limits where we could read them, and identity checks that can be triggered at withdrawal. Affiliate material that presents these as 7 separate casinos is describing one product in several colours. The licence holder differs: Donbet shares MyStake's, and the other 5 do not.

The differences that remain are short. Donbet leads with sport. Velobet pays cashback without wagering. Rolletto has the biggest cap and the hardest wagering. Goldenbet pays cashback on request. Cosmobet stretches its welcome over 4 deposits. Zizobet has the largest headline. Nothing else is shared: each brand has its own registration, balance, verification and self-exclusion.

How the ownership links were checked

GTW B.V., a Curaçao company (No. 165433), operates MyStake and Donbet under licence OGL/2024/250/0115, with CYGTW LTD of Cyprus named as payment agent. Santeda International B.V., company number 151296, operates Velobet, Rolletto, Goldenbet, Cosmobet and Zizobet under licence OGL/2024/1798/1048. We read each brand's footer or company details page in September 2026. The test a reader can run is the same: a site whose footer names GTW B.V. and OGL/2024/250/0115 is on MyStake's licence, and one that names Santeda is not. The test confirms a shared licence, so read it as strong evidence of a sister relationship, not absolute proof of one.

MyStake's company details: GTW B.V., licence OGL/2024/250/0115.

Velobet's company details name a different holder: Santeda International B.V., licence OGL/2024/1798/1048.

The 5 Santeda brands belong in this comparison for a different reason. In February 2026, NEXT.io reported the group moving its brands' footers from Santeda to GTW, and in April 2026, the Guardian described MyStake as one of at least 8 apparently connected brands on the same network. As of September 2026, only MyStake and Donbet had made that switch in their footers.

Two caveats attach to both companies rather than to any single brand. As observed in the Curaçao Gaming Authority's licence registry edition of 20 August 2026, both licences showed an expiry date of 24 December 2025 and a status of assessment in progress. In May 2026, NEXT.io and GamblingNews reported that both Santeda International B.V. and GTW B.V. had been dissolved, while the sites kept trading. All 7 were still online when we checked in September 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 its protections. 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 your first withdrawal isn't held for documents. Read the wagering deadline, the bonus win cap and the €15,000 monthly limit before depositing money you would mind losing.
