I wonder how is the traffic of your site after you are on your 6th month? Is it good enough? As I just checked for a while, there is only few bets under the all bets tab which most likely just faucet betting. It is just too unfortunate if you have so low traffic while you have good game, at least the roulette is not just like other roulette game at other sites.
You need more promotions IMO, something like competition/contest where players need to make deposit would be better than giveaway. By the way, how much is your bankroll currently as I cant find the max bet/profit per bet allowed on your site? Sorry if it has been asked before.
