Actually we work with many more providers than any other casino. Which provider did you not see?
My bad, I did not notice the full list of the available providers in your casino.
After checking it again, yes you have almost all available popular providers, so apologize for my previous comment.
Which category can we use? Because as far as we know, we can only open one topic in this category.
You can create separate topic in the Games and Rounds board, this is the board for any casino to open thread for promotion.
You are free to create many threads for your promotions (1 thread for 1 promotion).
