In short, a brand name can't be attractive by itself, it's services, or, site functionality, associated with it what makes it attractive. The only thing which is really important when picking a brand name is its otherness. If you are making a gambling site that is much more fun to play on than on the similar sites, pick a name which is very different from other sites.
Indeed, right! If you wanted to separate you from other casino sites who offer the same features, make or create a name that's unique and attract gamblers to try your services, once you get them engage to your site and you made them satisfied with how you treat them and how you give them additional perks to continue attracting them to keep coming back,
your unique name will give an impact from them not to forget about visiting and playing to your platform.~
One might argue that you could just bookmark the site, and whatever it's name, even if you completely forgot it, you'll be there anyway. True, but not all of us are playing from our mobiles(I personally never play from my mobile to have a guaranteed break when not at home). And when you want to tell your new friends at some party about a great gambling site you've found, that's when a unique name comes in handy.
