Santeda International B.V. Casinos

Santeda International B.V.: Company Overview

Santeda International B.V. is a Curaçao company running several casino and sportsbook brands under a single licence. Its role across the Santeda International B.V. online casinos is operational, since brand footers, terms and regulator certificate pages all name it as operator. A Cyprus company, Santeda International Limited, appears in the same footers as the payment agent for the licence holder. No document reviewed names the group's beneficial owner.

Verdict in brief: Santeda International B.V. operates 5 verified brands under 1 Curaçao Gaming Authority licence, per certificate pages checked on 14 October 2026. None of the 5 appears on the Gambling Commission's public register. For UK readers, that register result outweighs every difference in bonus caps or deposit limits.

Santeda International B.V. Casino Sites: List and Comparison

The 5 casinos operated by Santeda International B.V. listed below were selected on one criterion applied to every candidate. Each brand's own terms or footer names Santeda as operator, and a regulator certificate page names it too. Press reports link further sites to the same group, including MyStake and DonBet, which fall outside that double test. A guide to sites similar to Cosmobet discusses MyStake alongside the brands profiled here, which helps readers trace the wider press claims. Counting only double-documented brands makes the total a floor rather than a ceiling, because further brands may share the operator without saying so.

The same test removes sites that merely look related. NEXT.io's June 2026 list of sites hit by a supplier outage included Freshbet among the affected brands. However, an Australian regulator's warning names a different Curaçao company, Ryker B.V., as the provider of Freshbet. A separate guide to Freshbet sister sites covers that brand's own network and its relationships. Shared code or shared outages do not establish a common operator.

None of these restricted-country clauses names the UK, but that silence is not permission to serve British players. Since the Gambling (Licensing and Advertising) Act 2014, operators serving consumers in Britain have needed a Gambling Commission licence. All 5 brands rely instead on Curaçao, the jurisdiction covered by a broader guide to Curaçao-licensed casinos. The shortlist below rests on documentary criteria alone and is not a recommendation to register.

• Clearest sterling figures: Zizobet's terms state its standard weekly withdrawal cap as £7,500, with a matching monthly cap of £15,000.
• Most recently dated terms: Cosmobet's general terms show an update date of 5 May 2026, the latest among the 5 brands.
• Clearest free-spin wagering basis: Goldenbet requires 10x the free-spin winnings within 7 days.
• Longest inactivity window: Cosmobet and Goldenbet allow 12 months before dormancy fees begin.
• Strongest warning signal: Goldenbet is named in a formal warning from Australia's media regulator.

Santeda International B.V. Casinos: Brand Profiles

Cosmobet: Latest-Dated Terms

Cosmobet carries the clearest paper trail of the 5 brands profiled. Its terms, footer and Curaçao Gaming Authority certificate page all name Santeda International B.V. as the operator, using the same company number. The general terms are dated 5 May 2026, which is the latest date shown among the brand documents. Its platform directory lists e-wallets such as Skrill, Jeton and MiFinity casino payments beside several crypto processors. That directory shows configured providers, not the methods actually open to players in any given country.

• The UK version of its terms drops the operator paragraph found in the standard version, so the company number disappears for visitors routed to that text.
• Readers tracing related brands can turn to this overview of Cosmobet's sister brands for wider context.
• The UK version also removes sterling from the list of accepted currencies, although the standard version includes it.

Rolletto: Multiple Certified Domains

Rolletto operates across more certified web addresses than any other brand in this comparison, with each address tied back to the same licence. Curaçao Gaming Authority certificate pages name Santeda as operator of rolletto.com, rolletto.cc and rolletto.win. A fourth domain, rolletto1.com, carries a seal token that returns the rolletto.cc certificate. Its footer names both the Curaçao operator and the Cyprus payment agent in the same paragraph, matching the wording used at Cosmobet and Velobet.

• Deposit-bonus winnings are capped at 10 times the deposit that activated the bonus.
• Sports bets below odds of 1.30 may not count towards wagering, per its terms.
• Rotating domains leave the operator unchanged but make the current address harder to confirm, especially when a seal token points to a different domain.

Goldenbet: Regulator-Warned Brand

Goldenbet alone among the 5 faces a published regulator warning. The Australian Communications and Media Authority (ACMA) issued a formal warning to Santeda over the Golden Bet service. According to the ACMA, its investigation began on 15 September 2023, when the service ran at goldenbet.com. Goldenbet's footer also describes Santeda as owner and operator, wording the other 4 brands do not use in their operator statements.

• Its UK terms say it "has passed all regulatory compliance" without naming any regulator.
• Free-spin and free-bet winnings carry 10x the winnings in wagering, due within 7 days.
• Bonus withdrawals are capped at 10 times the bonus amount rather than the deposit.

Velobet: Lower Deposit Threshold

Velobet sets a lower entry point than most sister sites. Its minimum deposit is half that of Cosmobet, Rolletto and Goldenbet. The trade-off sits in a stricter dormancy clause. A Velobet account counts as inactive after 60 days without a login, matching Rolletto but far short of Goldenbet's 12 months.

• Velobet's terms allow a 20 per cent cut when a withdrawal comes before the deposit is wagered 1x the deposit amount.
• Investigate Europe reported in April 2026 that Velobet appears on French, Italian and Polish regulator blacklists.
• That report gave no dates for the individual listings.

Zizobet: Sterling Withdrawal Caps

Zizobet runs on a different front end from the other 4 brands in this group, which makes the shared operator easier to miss. Its terms and About Us page still name Santeda, and its certificate page confirms the same licence. Zizobet is also the only brand whose withdrawal caps are written in sterling as well as other currencies. A separate guide to Zizobet sister sites maps comparable brands.

• Standard caps are £7,500 per week and £15,000 per month.
• VIP caps rise to £15,000 per week and £30,000 per month.
• Wins above £15,000 may be paid in monthly instalments of up to £15,000 until settled.

Santeda International B.V. Ownership and History

Current Ownership and Parent Company

The question of who owns Santeda International B.V. has no documented answer in the available record. Brand footers describe the Curaçao company as "license holder and parent company" of its Cyprus payment agent. That wording establishes a parent role over Santeda International Limited and nothing more. It says nothing about the shareholders who sit above the Curaçao company, whose identities the brand documents never disclose.

Investigate Europe, reporting with the Guardian on 1 April 2026, examined the group's links to the software firm Upgaming. Its reporters found several Santeda-linked domains registered by Upgaming or by the supplier's chief executive. Even so, the report said it had seen no evidence that either owned or controlled Santeda. Upgaming's lawyers denied ownership of Santeda or its casino domains and said the business relationship ended on 30 March 2026.

Licence History and Registry Status

The documented Santeda International B.V. history starts with its current licence rather than its incorporation. Certificate pages show licence OGL/2024/1798/1048 granted on 14 August 2024. Investigate Europe reported that the company was originally named Onyxion, without giving a date for the change. Velobet's page code still holds a disabled seal from the older Curaçao eGaming verification service, commented out beside the current certificate container. As an inference only, that points to an earlier sublicence under Cyberluck, which NEXT.io named alongside Santeda in a July 2026 court report.

Registry status is the material unresolved point for every brand. The Curaçao Chronicle reported on 22 April 2026 that the company left the Commercial Registry on 9 April 2026. NEXT.io reported in June 2026 that the licence had moved to a vehicle called GTW, which was later dissolved. Neither report matches the certificate pages, which still name Santeda with Active status on 14 October 2026.

Network Structure and Shared Services

Ownership, Operation and Platform Supply

All 5 brands sit under one licensed operator rather than a white-label arrangement with separate licensees. The Santeda International B.V. casino network has 3 documented layers, and each rests on different evidence. Its operating layer is Santeda International B.V., named on every certificate page and in each brand's standard legal texts. Santeda International Limited in Cyprus forms the payment layer, named in footers as payment agent. Of the 3, the platform layer is the least clear.

Cosmobet, Rolletto, Goldenbet and Velobet load the same front-end scripts and content endpoints from their own domains. Zizobet uses a different interface built on another framework, but the same content routes serve its footer, terms and About Us texts. That shared code supports an inference of a common platform without identifying the supplier, and no current supplier is named in the brand documents. Upgaming told Investigate Europe it supplied business-to-business services only. NEXT.io later reported that the underlying platform stayed the same through the June 2026 outage, even as several game suppliers left.

Shared code also governs what British visitors see on each site. The seal script used by Cosmobet and Zizobet removes the certificate seal for visitors located in Britain, Ireland or the US. In all 5 brands, the UK versions of the footer, terms and About Us texts omit the Santeda operator paragraph. A UK visitor reading only the site may therefore never learn which company runs it. That gap matters for any complaint or legal claim.

Shared Accounts and Cross-Brand Rules

Santeda International B.V. sister sites publish near-identical account rules, but each rule is written for a single site. Each provision below appears in all 5 sets of general terms. The wording varies slightly between brands, but the substance does not:

• Only 1 account is allowed per person, household or IP address on each site.
• Bonuses are limited to 1 of each per user, device, address, card and payment account.
• Third-party deposits are refused, and payouts go only to accounts held in the player's own name.
• Accounts sharing a payment account or crypto wallet can all be closed, with 20 per cent deducted from the deposits returned.
• Winnings from duplicate accounts can be reclaimed after termination.

No terms address accounts held at a different Santeda brand. The documents therefore cannot show whether a closure at Rolletto affects a Cosmobet account, or whether one verification can serve both. Balances, loyalty status and verification are likewise described per site, so standing at one brand carries no documented weight at another.

Licensing, Regulatory History and Player Protection

Licences and Regulatory Record

The Santeda International B.V. gambling licence is issued by the Curaçao Gaming Authority under number OGL/2024/1798/1048. Those certificate pages cite the National Ordinance on Games of Chance of 2024 as the legal basis. Brand footers still cite the older 1993 offshore ordinance, so the two sets of documents disagree. On 14 October 2026, the Gambling Commission register showed no business, trading name or domain matching Santeda or its 5 brands. Any operator serving consumers in Britain without that licence acts unlawfully.

The regulatory record outside Curaçao is adverse and dated:

• Australia: Australia's ACMA issued a formal warning over Golden Bet after an investigation opened in September 2023.
• Greece and Sweden: Investigate Europe reported in April 2026 that authorities in both countries had blacklisted Santeda.
• Britain: the same report found the Commission asked Google to remove 5 of 8 Upgaming-linked sites, citing the Lumen database.
• Curaçao courts: NEXT.io reported that Santeda lost a first-instance player-winnings case on 31 March 2025.
• Spain, Portugal and France: some sites showed court or administrative blocking notices there in June 2026, NEXT.io reported.

Complaints and Responsible Gambling

Complaints go first to each brand's support team, and Cosmobet, Rolletto and Goldenbet require them within 2 months. Cosmobet's dispute page names no alternative dispute resolution (ADR) body. It points instead to "any independent body" on the website. Legal proceedings belong in the courts of Curaçao, per Cosmobet's dispute page and Zizobet's terms, which name no forum in Britain.

Self-exclusion works brand by brand, and the published pages set out a narrow process:

• Players request self-exclusion by email to each brand's support team, for between 6 months and 5 years.
• Goldenbet, Velobet and Cosmobet default to 6 months when a player gives no period.
• Cosmobet's responsible gaming page also lists account limits and cooling-off periods, arranged through customer support.
• None of the self-exclusion pages says that an exclusion extends to other Santeda brands.

Without a Gambling Commission licence, these sites sit outside the UK protections that apply to licensed operators, including GAMSTOP's national scheme. That gap is a further reason the brands offer UK readers no regulated option. Anyone worried about their gambling can contact GamCare or the National Gambling Helpline for free, confidential support.

Bonuses Across the Casino Brands

Offer Structures and Wagering

The Santeda International B.V. brands use a common bonus rulebook with a few local variations. None of the general terms states a wagering multiple for the main welcome bonus, so the multiple sits outside the documents compared here. They say only that deposit bonuses "have wagering requirements", so headline offer figures are omitted here. The caps, by contrast, are explicit and define what any bonus can actually return:

• Deposit-bonus winnings are capped at 10 times the qualifying deposit at Cosmobet, Rolletto, Velobet and Zizobet.
• Goldenbet caps them at 10 times the bonus amount instead.
• Cashback withdrawals are capped at 5 times the cashback amount.
• Wager-free cash bonuses pay at most 5 times their value.
• Every deposit must be wagered 1x the deposit amount before withdrawal.
• At 4 brands, an expired bonus is removed together with any winnings made after its activation.

Caps matter more than headline numbers in this group. Bonus codes listed on comparison sites, including a general page of casino bonus codes, cannot override a brand's own caps. A cap tied to the deposit gives a larger ceiling than one tied to a smaller bonus amount. Goldenbet's free-spin rule is the only one with a stated basis and deadline, at 10x the winnings within 7 days.

Eligibility Across Sister Brands

Bonus eligibility is set per site, using the same household and device tests at each brand. The terms do not say whether claiming a welcome offer at one brand blocks it at another. Rolletto and Cosmobet exclude players from Thailand, Finland and Japan from deposit and welcome bonuses, and reserve the right to add countries. Goldenbet publishes a far longer bonus-excluded list that includes Greece and Georgia, with Finnish players limited to its 10 per cent cashback.

Offers such as deposit £10 free-spin deals at licensed sites can be tested against the same 3 checks of wagering basis, withdrawal cap and expiry. A free-spin offer without a stated cap leaves the most important figure unknown. Goldenbet's 7-day deadline shows why expiry belongs among those checks.

Games, Software and Mobile Experience

The game catalogue is the least stable part of these sites. NEXT.io reported that several suppliers withdrew their games on 14 June 2026, emptying some slot lobbies for hours. The same outlet reported the sites live again by the next day, with several suppliers still present. A supplier's name in a shared platform directory therefore says little about which games a player can open on a given day.

The terms of Cosmobet, Rolletto and Goldenbet carry a specific restriction clause for NetEnt casino games. That clause bars play from the US, Curaçao and the Netherlands. Campaign to End Gambling Ads claimed that 18 Gambling Commission-licensed suppliers featured on MyStake and DonBet, which it links to the Santeda network. The Betting and Gaming Council told Bloomberg that some of those games did not appear to work.

Cosmobet's fairness page says a "reputable licensed laboratory" certified its random number generators but names none. A certificate from a named body such as eCOGRA's testing service would identify both the laboratory and the scope of testing. Cosmobet's fairness page offers neither of those details. No dedicated app appears in the brand terms, and the 5 brands run as browser sites with mobile versions.

Payments, Withdrawals and Account Checks

Payment Options and Withdrawal Conditions

The withdrawal rules are close to identical, which narrows the real differences to a few figures. Cosmobet's platform directory lists Santeda International B.V. payment methods across cards, e-wallets, bank transfer and crypto. Across the 5 brands, the terms set these conditions:

• Cosmobet, Rolletto, Velobet and Zizobet process withdrawals within 3 banking days, and Goldenbet states this for bank transfers.
• No brand states a transfer time after processing.
• Payouts generally return to the deposit method, per Cosmobet and Rolletto.
• At 4 brands, fees may apply when bets since the last deposit total under 3 times that deposit.
• Velobet and Zizobet set a lower minimum withdrawal.
• Withdrawals above a payment method's limit are paid in instalments rather than refused.

The 3-banking-day figure is the operator's own processing estimate, published in its terms, and covers only the operator's side of the transaction. It is not demonstrated performance, and identity checks can pause it at any stage. Weekly and monthly caps appear at 4 of the 5 brands. Only Zizobet expresses those caps in sterling as well.

Identity Checks Across Brands

Verification rules are the same in substance at all 5 brands. Documents must be supplied in the Latin or Cyrillic alphabet. Where that is impossible, the operator can require video verification instead. Cosmobet, Rolletto and Goldenbet allow 30 days to supply requested documents before treating the request as failed. The terms and Cosmobet's KYC policy add these conditions:

• Proof of residence can be a bank statement or utility bill no older than 6 months, per Cosmobet's KYC policy.
• At Cosmobet, Rolletto and Goldenbet, suspected identity irregularities can lead to closure and a refund of the last deposit minus 20 per cent.
• Withdrawals can be held for as long as an identity check or terms investigation takes.

No terms say whether verification transfers between brands. Each site may therefore ask for the same documents again. Cosmobet's KYC policy also allows a risk assessment covering a client's source of funds and transaction volume.

Verdict on Santeda International B.V. Casinos

Santeda International B.V. casinos form a genuine single-operator group, documented by regulator certificates, brand footers and the general terms of all 5 sites. The 5 brands share one Curaçao licence, one rulebook and near-identical account restrictions. Their differences are narrow, covering deposit minimums, dormancy periods, bonus-cap bases and currency wording. Those differences do not alter the central finding for UK readers.

No brand earns a recommendation for players in Britain, because none appears on the Gambling Commission register. UK readers seeking a regulated alternative can start with a list of Gambling Commission-licensed casinos instead. A licensed multi-brand group offers the closest structural comparison. One example is 32Red Limited's casino brands, which can be checked against the same ownership, account and payout criteria used here. For existing customers outside Britain, Zizobet's terms are the most explicit on withdrawal caps, though the dissolution reports remain unresolved.
