Dunder Casino review

Ok so where do we start! Dunder Casino is a brand new casino launched in March 2025. It’s brought to you from the fine folks at Casumo Casino which is another new casino that we thinks great. Read our Casumo Casino review for more on that! We have to say that we think this is going to be one of the biggest releases of 2025.  The past year has seen some epic new casinos aswell as updates to old ones like; Rizk Casino, SuperLenny Casino, Mr Green and Guts Casino but Dunder Casino seems to have taken all of the best bits from these and created a casino that ticks all the boxes!

The website itself is simple but stunningly well put together. The layout and look is very modern and everything is well placed for you to find your way around easily. The slots and games are very well categorised and Dunder Casino has created it’s own set of helpful categories too.

Slots and casino games

Dunder Casino boasts over an incredible 1000 slots and games! We struggled to find another casino that could match this massive selection. They also have the best providers on board;

• NetEnt
• Microgaming
• Play N' Go
• NextGen Gaming
• Thunderkick
• Evolution Gaming

This means you get to play on slots like brand new NetEnt slots like; Aloha Cluster Pays, Guns N Roses, Koi Princess and also favourites like Gonzos Quest and Twin Spin. You’ll also get to play other player favourites like Avalon, Jurassic Park, Immortal Romance, Piggy Riches and Gemix. This is obviously just a flavour of what you’ll get at Dunder Casino so take a look for yourself.

Dunder Casino haven’t just put all the effort into slots. There’s a good variety of table and card games to choose from too including; Roulette, Poker, BlackJack and Live Casino. Take a look at this section as there’s loads of variations of each game.

Customer support

Good customer support is massively important and Dunder Casino has done things right. There’s no phone number to call but that’s fine by us. What we always look for is Live Chat, which they have available between 10am-10pm 7 days a week and also a decent FAQ section. In the FAQs you’ll find answers to loads of common questions that should get you sorted!
