As a result, gamblers often look for online casinos that offer many promotional bonuses, especially welcome bonuses, in addition to cashback, weekly bonuses, and other perks.
This is why some casinos without these "gimmicks" are slowly being eaten up by their competitors. That's why in this day and age, it's no joke to keep up with competing online casinos.
they say, only the strong will survive.
Correct. Honestly, why would user still stick to the casino that less rewarding while there’s a lot of other casino that offers much better bonus and benefits to their loyal customers just to stay or attract VIP to transfer.
Casino offers same game from same provider. They can’t use the game itself to attract players because it’s already common to all casino unlike before that casino offer exclusive games only such as dice, crash and more on single casino like Primedice, Bustabit and so on.
Maybe for familiarity? usually there are people play because they think they are lucky with this casino.
But for sure that kind of feeling is not sustainable especially as what you have said there are lots of casinos offering such nice or more rewarding promotions. So if they can't compete with those casino offering some attractive rewards to their gamblers so there's a chance that many of their loyal gamblers would provably hop in on their competitors.
Right now people are not looking for the games since they could see it everywhere. What usually they look is if the casino is generous for giving such nice bonuses to their players.
