I'd say yes, because those who play calmly and without a strong urge to gamble often want to test their luck on other sites. Considering that regular players who aren't addicted to gambling can play on one to three sites and calm down, calmly stop playing for three months or six months, and sleep soundly. However, it's also important to note that sometimes the number of sites isn't an indicator, as in reality, you can lose several times more in a shorter period of time on just one site, which, of course, also looks like a gambling addiction.
