"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."

"It is fairly common for casinos to offer free blackjack or craps lessons. Not only can you learn how to play these games for free, but often times lessons include bonuses like match coupons."

"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 modern slot machine was born in 1984, when a system of using a Random Number Generator to determine the sequence of stops was invented. This allowed for reels with as many as 256 stops."

"The most confusing type of slot machine are the 'Buy-a-Pay' machines. On these, the payout for wins is based on how much you bet, where playing anything other than max coins doesn't make sense."
