Dunder Review

While the name may not exactly hold the most positive connotations in the English language, in Swedish, Dunder is ‘Thunder’ and, with such a strong, commanding name, you’ll be expecting the same from the casino that holds it. Dunder do not disappoint. Their site is bold, their game selection is broad and they’ve got customer support pegged.

When we first get wind of a new casino the first thing we look at is behind the scenes. Who is running it? What licenses do they hold? Before we start looking at things like games and the aesthetics of the casino itself. From the very first glance, Dunder looked like it was set for great things. The founders of Dunder have the complete backing of two of the most popular casinos around today- Casumo and Guts.

When it comes to licences, Dunder do not disappoint- with a European gaming licence issued in Malta and another, from the UK, in the pipeline. They also offer their site in four languages- English, Swedish, Finnish and Norwegian, and players can deposit using any one of numerous trusted payment methods- from Visa to Skrill, Trustly to EcoPayz.


Dunder’s site is bold yet unassuming. You’ll find their games selection easy to sort thanks to the neatly organised categories, the stark white background leaves it feeling clean and the whole site is based on images rather than text (and frankly, who wants to be reading through reams of text before they can play!). Bar the ‘join’, ‘log in’ and ‘games’ tabs along the top, everything else is all tucked away into a single menu bar in the left corner.

NetEnt fans won’t be let down at Dunder; they offer nearly every NetEnt slot in circulation, NetEnt live casino, NetEnt touch for mobile casino players and, unusually for a newer casino, all the most popular jackpot slots- from Hall of Gods to Mega Fortune and the local jackpots to boot.


We have no reason to doubt Dunder’s trustworthiness. They have an aforementioned European licence, so have jumped through all the necessary hoops, they offer very fair 25 x wagering requirements on their welcome bonus (substantially less than the industry standard) and their terms and conditions are well-laid out, well-written and (unlike some) easy to find, not squirreled away in a corner somewhere.


There are literally dozens of reason why you should consider trying Dunder. With their links to Casumo and their Malta gaming licence in hand they come highly recommended, their welcome bonus is huge and their wagering requirements are tiny. Love NetEnt slots? They have virtually every one in existence, plus a hefty bunch from other providers too. We know we’ll be signing up.
