Casino Sister Sites Directory

Casino sister sites are brands run by the same operator, often on a shared licence and cashier. This directory maps those families by brand and by operator. Each profile covers bonus terms, games and risks, so the differences are clear before any deposit.

What Casino Sister Sites Are

An operator is the company that holds the licence and runs a casino. Casino sister sites are brands that share 1 operator under different names. Each brand keeps its own lobby, theme and welcome offer. The licence pattern, cashier and support desk usually sit at group level, so 2 brands from the same family feel familiar on a first visit.

Shared ownership does not mean identical terms. Brands in a group differ on wagering, withdrawal ranges and loyalty rules, and a welcome offer at 1 site says little about the next. A shared operator also means shared exposure, since a complaint at any brand in a group reaches the same company. The guides below separate what carries over from what stays brand-specific.

Featured Operator Networks

Santeda International B.V.

6 brands sit under the Santeda International B.V. name, all on Curaçao Gaming Authority licensing. Each runs its own lobby and welcome offer, and the differences are concrete. Each brand and its main point of difference follow.

• MyStake: a sportsbook with a casino lobby, Galaxy points convertible to cash and 300 per cent across 3 deposits at 30x on deposit plus bonus.
• Donbet: casino, sports and crypto welcome tracks, with 150 per cent up to £650 plus 50 free spins at 30x on the bonus.
• Rolletto: the broadest crypto range in the group, with 150 per cent plus 50 free spins on deposits of £15 to £375 at 30x on the bonus.
• Velobet: the largest library at 8,000+ games, with 150 per cent plus 70 free spins at 30x on the bonus.
• Cosmobet: 330 per cent across 3 deposits at 30x on the bonus, each deposit on its own wagering clock.
• Goldenbet: 100 per cent up to £435 at 30x on the bonus, plus a 10 per cent daily cashback on losses.

These differences sit on top of shared risks. The 6 brands share 1 operator and 1 licence pattern, and none holds a UKGC licence. An April 2026 press investigation named MyStake, Velobet and Goldenbet among casinos accessible in the UK without one. The operating company was dissolved on 9 April 2026, which makes the licence holder's status the first thing to check before any deposit.

Why Ownership Matters Before Registering

Ownership shapes 3 things a player can check before registering. The basis for each is stated below, and the brand guides carry the figures.

• Bonus eligibility: verification records and bonus eligibility can overlap across brands that share an operator, so the terms on each brand page govern.
• Dispute route: a complaint at any brand in a group reaches the same company, and the licence issuer decides the escalation route.
• Licence position: the issuer and its protections apply across the group, which is why each profile names the licensing body.

A licence from the UK Gambling Commission adds an approved route to independent dispute resolution. It does not guarantee any outcome for the player. A licence issued outside the UK offers no such route, and escalation options are limited to the operator's own complaint process.

How OtherPlay Compares a Group

We compare each operator network on 7 criteria, applied the same way to every brand.

• Welcome terms and wagering base.
• Library size and provider mix.
• Loyalty and cashback structure.
• Payout timing as published.
• Regulatory record and licence position.
• Player feedback and sample size.
• Banking range and dispute routes.

Figures are quoted as the operators and reviewers publish them at the time of writing, and each brand page carries its own date. The How We Review page sets out the full process.

Casino Alternatives Beyond the Network

Casino alternatives fall into 2 groups, sister sites with a shared operator and casinos from other operators. Inside a network, welcome packages are larger and crypto banking is common. Casinos from other operators sit in a different regulatory position, and the licence decides the dispute route.

Betway is the clearest example outside the Santeda network, judged on holding an active UKGC remote casino licence as of 9 October 2026. UK-licensed casinos cap wagering at 10x on the bonus and offer approved independent dispute resolution. The trade is smaller offers and no crypto banking in return for a binding complaints route.

Gambling carries a negative expected return and is not a source of income. Support is available from BeGambleAware.
