1.1 What are Sister Sites?
Sister sites are online casinos sharing a common owner or under the management of the same group. Usually, they work under the same license and could have the same software providers and payment options. Probably the biggest plus of sister sites is consistency. If you like the interface, games variety, or bonus offers on one casino in a network, you’ll likely find the same benefits on its sister platform. This allows for easy switching between sites and also assures a high level of trust and dependability.
1.2 How We Review & Rank Sister Sites
We start with Licensing & Security, checking if casinos hold reputable licenses, for instance, UKGC and MGA, and verifying SSL encryption and fair gaming certifications. Next, we assess Game Variety & Software Providers, looking for a broad selection of slots, table games, and live dealer options, plus top-tier developers like NetEnt and Microgaming. We also look into the Bonuses & Promotions, making sure that welcome offers, ongoing deals, and loyalty schemes have reasonable terms and wagering requirements.
We then consider Payment Methods & Speed, going for casinos that can offer a variety of deposit/withdrawal options, including credit cards and e-wallets, and fast payouts without fees. Finally, we test Customer Support & User Experience, checking live chat, email, phone support if available, and mobile compatibility. By focusing on these areas, we recommend only those casinos that excel in security, variety, fairness, and support.
1.3 Provably Fair
If you’re looking to play in a crypto casino, you should familiarise yourself with the term ‘Provably Fair’ which is a mathematical algorithm used by many online casinos for the purpose of fair play.
The algorithm used is to ensure that all results of the bets are totally random and therefore cannot be hacked by anyone to give a guaranteed outcome. From the players’ perspective, casinos should not be able to prevent players from ever winning, and from the casinos perspective, certain players should not be able to influence the outcome over other players.
All of them should have an equal chance to win the games. This is why any crypto casino that offers provably fair games can be considered more trustworthy as a result and these are the best ones to look for when you want to gamble online.
1.4 Bonuses and Promotions at Sister Sites
1.4.1 Common Types of Bonuses
- Welcome Bonuses: Deposit match, free spins, or a no-deposit offer.
- Reload Bonuses: Ongoing promotions for returning players.
- Cashback Offers: A percentage of losses returned as bonus funds.
- VIP & Loyalty Schemes: Tier-based points for consistent play, often redeemable for cash or prizes.
Important: Always check the wagering requirements. Even sister sites within the same group can tweak their terms. A 35x requirement on one site might be 40x on another, so if you love minimal rollover, choose accordingly.
