Dunder Sister Sites – What’s It All About?  

Let’s be honest, the online gambling market in the UK is a confusing place at the best of times. If you’re not sitting there wondering what on earth a Megaway is, then you’re probably being baffled by the latest free spins terms and conditions, or routing through your cupboards to find the right ID to verify yourself at your next casino.

And to cap it all, there are literally thousands of sites to choose from. So, where to start?

Well, one way of making a choice is to look for brands that are similar to ones you already hold an account with. In many cases, your favorite casino will be part of a group and operated by one license holder. These sites will offer the same games, very often have the same customer support team behind them, and comp their customers with a similar set of loyalty rewards.

So, that brings us to Gaming Innovation Group (GiG), a Malta-based gambling business whose subsidiary, MT Secure Trade are the licensors for Dunder Casino and a number of ‘sister sites’ that also run on the same platform. What you get at Dunder, you will get more of at sites in that group – sites like the ones listed on this page. If you’re savvy enough to know this, which you now are from reading this, then it’s going to help you cut through the noise and find a new casino that you can confident you are going to enjoy.

So …

The majority of casinos on this page are owned and operated by Gaming Innovation Group (GIG) or MT Secure Trade, a division of GIG. That means that not only will you be impressed with the range of games on offer, but you will also be familiar with the kind of promotions available, including plenty of rewards and level-ups for those who continue to play regularly.

Each of our Dunder Sister Sites is also licensed by the UK Gambling Commission and the Malta Gaming Authority.


We have recently added a few new casinos to the list that don’t come under the GIG umbrella. Casinos like Temple Nile, run by White Hat Gaming, and Genesis Casino from Genesis Global, are new, vibrant places to play slots and share all the characteristics of the best GIG sites. They have huge game catalogues as well as offer really generous sign-up bonus packages, including plenty of free spins. They also come with a very good reputation amongst UK gamblers.

Like all the casinos featured on The Slot Buzz, the sites listed on this page have been comprehensively reviewed by our team so that you can learn all about what’s on offer before signing up. You will also be able to note the significant terms and conditions of each site’s welcome package so that you know what you are signing up for – this includes any restrictions on what you can do with winnings from free spins. So, if you’re not sure which site is for you, make sure you click through and read each article before you decide where to play.
