Thank you everyone for your answers! Seems like signature campaigns will be my first move.
That is the best way to promote , but of course Handling events will also carry your advertising , but most important thing is Which Manager will you hire to do the Job, we have seen many casinos that managed by their Own team that gets no success , until they pass to legit and trustworthy manager .
so best to choose better one and never keep small budget for the advertising because this will be your weapon in luring players, the more you spend in Ads is the more gamblers will trust your team , because this involves money and the more you can spend is the more you can be trusted.
and also never expect fast return , sometimes this will take long before you get what you wanted so please don't be like those who advertise for 2 months and expect thousands of players instantly .
