Every individual has their own unique and different expectations when they visit a casino and if those expectations are met, they would most likely stick to those casinos. Most of the times it’s not really about the games because almost all the casinos have the same game. For some it could be the user interface, for some it could be how fast their customers support system responds to customers, for others it could be how fast the deposits and withdrawals are, so when opening a casino these are the things you need to consider first, know what gamblers really expect from a casino and see if you can bring their ideas to life.
It is better for a gambler to have no expectation from the gambling site they are using and it is wrong for a gambler to expect too much from a casino when they are supposed to gamble responsibly. If there is any legit way to increase the outcome we get as a gambler while betting, this does not mean that we can expect too much apart from what we have at hand as a gambler.
