I think games and rounds would be enough, you can however have the announcement here that is allowed, so what you would do is post the competition thing here, with a link to your main competition topic at games and rounds, which would help you out. And everyone will talk about it there as well, that way you would get attention from two places.
You want it to make this website a lot more visible and talked? You can post here every 6 hours (or 12, or once a day whatever you want) post about it here, like "do not forget about our promotion at games and round, go join there" and you can keep doing it. So, basically you will do it on games and rounds which many many people will join and make the website get attention on that section while you make this place get more attention.
Right now if you want to sucess in Casino or any field like this you must do some good marketing this surely attract new members and more wagering on your site right now we have few new casino's they are doing some good stuff and they have some good return of this so they surely check in Games and Rounds section and then they can do few things for their own site because without big prizes and competitions its very hard right now.
I have talked with a guy who owns a casino before and I can tell you that having a 6 month straight marketing that would get you super famous would cost about half a million dollars. I know you can do it for less or you can do it for more but you could definitely do it for half a million dollars that would be proper.
The 200k would be for spending on signature campaign and the campaign manager, you could have a huge one out there with over 50 people from senior member to legendary and all that, it would go on for 6 months, after that you can do 200k for ads everywhere you are allowed, I am not sure how google approaches it but you can put it on everywhere you can, and another 200k (with 100k coming back) would be weekly 1k wager, 6 months is about 24 weeks and that would be 240k but I am sure people who compete would lose some.
So, basically marketing is EXPENSIVE and really a lot.
