I support your suggestion. Review campaign can help the casino for the Op. But we don't know the financial capacity of the Op to start with campaign so to help him grow/develop the casino we can just do a glance review on the site by using it. And give give the brief review here. But if the Op is capable of carrying out a good review then no problem.
Well, first of all I would suggest OP to develop a more interesting ANN. Even though OP have bought the copper membership but I still not like the way he has presented the ANN. He need to make it a bit more attractive and simple too.
Next, Signature campaigns are much better way to promote the casino, but if they are low on budget a review campaign can help too where they can give certain balance at the betvada to gamble and share their reviews. Another option can be to offering incentives (e.g., bonuses) to players who leave reviews.
