So even if a casino has a great marketing strategy, if they lack the basic things that a gambler looks for, like good customer support, a user-friendly user interface, and obviously a good reputation, they will lose a lot of customers very shortly after gaining them.
It should be balance and features still most of what gamblers need since there are different types of gamblers and not all have same characteristic so the casino needs to consider different type of gamblers for them to have users. For me, good and easy to understand interface is needed as well having a fast response support team. The giveaways or promos will just be additional as long as it features variety of games. good interface, fast support as well fast deposit and withdrawal then it can be consider a good or potential casino..
