Yes, and there are still those players who are slots and sports bettors who move their bankroll to the bookmaker and regardless of the competition, they continue betting there and getting the odds or participating in exclusive slots.
Casino usually offers same game from same game provider. They just differ on the promotion they are offering so gamblers that keep jumping from different casino usually chase daily bonuses and competition.
Free daily tournaments and winning streak promotion is now very popular on every casino to encourage gamblers visit the casino daily and casually deposit just to be qualified on promotion.
I’m one of those gambler that regularly visit different casino to claim all those mini bonus and participate on some daily promotion.
