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.
I agree with panjul07, just by even putting up some graphical designs with your ANN thread will help you gain more attention compared to your plain and simple text ANN thread now. Just by the looks of it there is only one person actively playing at a time every 5 to 10 seconds, which for a roulette game is very low considering some gambling sites where roulette is not their main attraction they actually have more players compared to what they have. And that one active player betting is not a high roller. If you really want to swing some players to your site you should start giving promotions and also what other websites have like a referral system and even a chat box for your players to interact.
This game is a good start for developers. I really think this guys should make a good product, cause they start their story with a quality game. Of course we need another games to make it more interesting for players, and we will wait for it!
