"In order to keep the house edge, casinos offer games where they win outright more often or they offer games where the player may win more often, but doesn't get paid the true odds."

"The only game where the probabilities change is in blackjack, where every card dealt alters the probability of which card will be next. EV in blackjack can alternate between positive and negative."
