Yes, ‘thunder’ is the official translation of Dunder from Swedish. Why pick Swedish? That is where the operators originate. They are also big casino fans themselves. This means they have extracted everything they dislike and instead built in all their favourite casino features so you can have the best possible experience.
Founded in 2016 on the basis of friendliness, best choice of games imaginable, great service and, best of all, fast withdrawal times, this really is one of the best online casinos in the UK.
