I agree they need promotion or contest to make this thread more alive there are so many gambling sites who offer a good offers to their gamblers so best to follow them or maybe surpass them in terms of promotional matters for a successful result.
For now for what I see I think the marketing team of this site is lacking of strategy so maybe they should look at for that aspect to get more players.
There are many things to bring the casino to more people, and make it more attractive. Signature campaigns, promotions, contests, house edge and new games. With whatever promotions will be run, the casino should run multiple ones in the same period to get as highest net effects as possible. Effects will be higher if the period of promotions are longer.
It is a math of available funds, available attractive games on the casino, and marketing strategies. Basically, with limited funds, there are less options to do.
