"Slot machines are the bread and butter of the casino industry, accounting for three quarters of casino profits. All slot machines are pre-programmed to keep a portion of the cash put into them."

"There are no clocks in casinos because they want to make time seem slower; the longer you stay, the more you play. So don't forget to bring your phone or wear a watch."

"Roulette wheels are designed so that consecutive numbers are opposite each other, one opposite two, etc. The wheel also alternates between red and black while the green numbers, 0 and 00 are opposite."

"Although all slot machines look alike, no two models of machine are the same. Some are far better than others, and you should learn how to evaluate each machine to see if its worth playing."

"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."
