"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 mathematical probability of something happening is its true odds. Casinos maintain their advantage by paying players less than the true odds of their wins."

"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."

"You can't control luck, but you can control how well you play any game which relies on skill. Study and practice the game as much as possible before you play for real in the casino."

"Every slot machine is controlled by a computer chip containing the Random Number Generator. Whether the machine is being played or not, the RNG generates thousands of numbers per second."
