You might wonder why a site should have a sister or brother! 

For a site to be considered a sister site, there must be a relation between the sites. 

In most cases, sister sites in gambling are run by the same company or are part of a group of companies like Viral Interactive. These factors do not apply to all related sites, as some will operate autonomously and offer a different product. This is another function of a related site whose goal is to serve a different market from the parent company. 

You will find various sister sites in the bingo and casino world on our platform. For instance, JackpotJoy is a related site to Bally Casino and Virgin Games. Another example would be Double Bubble Bingo, a related site to Monopoly Casino, owned and operated by Gamesys Operations Limited. 

We have encountered many related sites in the UK market offering excellent gambling services, ranging from bingo to casino and live casino games. Our reviews will include unique features in the bingo or casino sister sites that match the level of gaming we believe meets world-class standards.

What is Sister Site

Are you wondering why we are referring to these sites as sister sites, not brother sites?

Since ancient times, ships or cities were named after women and were referred to as mother or sister; this is attributed to the productive nature of women. 

When it comes to the sites, there is always a parent site, which is the mother. One would refer to other related sites because they have the potential to sire another site, making it a parent site, too. With such reasoning in mind, you should call the related sites “sister sites”.

Most gambling sites serving the UK market will have a sister site focusing on the market or a different one. Most sister sites we recommend are for the UK market and will mostly offer casino games, bingo games, lotteries and live casino games. 

Some of the features that we come across with these sister sites are:

  • Operated by the same company
  • Serving the same market 
  • Some of the games are differentiated to serve different preferences
  • Similar bonuses or models of rewarding players
  • Similar user interface and theme

The bonuses are usually similar in sister sites, but this is not always the case. The welcome and reload bonuses will usually be the same across all related sites. Some that might differ are the bonuses specific to a game or the site’s focus. 

For instance, if you look at Mecca Bingo and Bella Casino, they are sister sites, but their bonuses differ in their offerings. The reason behind this is that Bella Casino is focused on casino games and slots thus, their focus is on free spins and casino bonuses, while Mecca Bingo focuses on the bingo games, which explains the many bingo offers. 

Sometimes, you play too much in one place and need a change, just like in a physical land-based casino. This is where the need for a sister site comes in; the related website will offer the same security, peace, and, above all, a changed environment for gambling. 

When a gambling entity has a related site, it shows the legitimacy and great investment in the services. The goal here is to give you options. From the sister sisters we review on this platform, we test their services, contact the support and verify their licenses. The benefits we list are exclusive to our findings on our reviewed casinos and bingo sites.  

  • Variety of games to choose from, ranging from bingo to live casino games
  • You have multiple platforms to choose from the same provider
  • You get more room to play since you are not crowded in one bingo platform

The main reason for this would be a restriction to enter the market. The UK gambling market has strict regulations to shield the players. With such a market, companies like Gamesys and Rank Interactive understand the industry, and the players have no option but to develop sister sites. 

Multiple sites serving different products in the gambling industry will serve the market with quality and adequately regulated platforms. 

This is why you will find sister sites focused on two different products, though related, like Casino and bingo. In other instances, you find related sites with similar products but a different theme!
