For example, if I created a casino today and named it SuzBet Casino. Gamblers are ready to try it out once it hosts a signature campaign on the forum and the experience they had while using the casino will determine if they trust it or not.
Good design is just to make the casino look good.
What matters is the overall performance of a gambling site. Players won't focus much on its brand name but on their promotions and bonuses as well as the smooth transactions that they could provide and also the gameplay experience. A good brand name might have an impact but it doesn't affect the whole reputation of the site.
Except that it is pretty common for the human psyche to associate popular brand names with quality service and exceptional experience with what these names offer. Much like luxury brands, gamblers also treat gambling platforms as such, with popular casino names as 'premium' platforms that offer way better things than to a normal casino. Believe it or not, it's easy for most people to be blinded by the name and fame of something.
@DoublerHunter, You understand my point and I wonder some people consider brand name has what makes a casino reputable. However, everything you talk about and a good bankroll is what new casinos need to gain the trust of gamblers.
@Cling18, Yes, 98% of all gamblers focus mostly on the smoothness of a casino withdrawal, bonus, and promotion. If casinos don't experience huge traffic when they had promotions they won't have to do it again.
@dothebeats, it may be common for the human psyche to associate with a popular brand but gamblers always try new/another casino to try their luck especially when they are having a promotion.
