OP I just noticed your casino now and from the looks you have been here for a little time now at least enough to be well known on this platform but it seems you are not ready for that as you do not have any plans to do that but however,i checked your website and it is good to visit but I can not see your license and your terms and conditions are quite alright. If you can, it would be nice you make out budget for your casino promotion and I will recommend Littlemouse for you as he is a good manager and can manage your campaign for you.
"They are here for a little time" or they are still a new casino, which is not enough for them to be well known but they can increase their exposure and trust of the people by doing some promotions as you suggested.
Another thing is being active on this thread. I see that their representative replies have some gap but it's nice that they are back again lately. It's normal for a new casino to not have a license and not having it had some benefits to some. Just be calm and watch out later on if what they are up to. They can either try their best because they want to be successful in this business or not. But they also have a reason for that.
