"The Random Number Generator on each slot machine uses a complicated formula to generate numbers. This algorithm is known to the authorities, who can test machines to ensure they are working properly."

"Short term results can fluctuate. Sometimes you win more than expected, sometimes you lose. This is called the standard deviation and this is what most people commonly see as 'luck'."

"Nearly every casino game in the world has an EV under zero, which means that the house has an edge over the player. You might win occasionally, but in the long run you will lose."

"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."

"The long run, so to speak, is the expected amount that you would win or lose if you played the game long enough to equal an average result. This is expressed as the EV, or expected value."
