"The first slot machine got the nickname 'The Bell', after the winning symbol. It was very profitable since there were a total of 10 symbols with1000 different combinations but the jackpot was only 750 coins."

"Turing a card over 10 times will statistically result in 5 reds and 5 blacks. If you bet $1 each time with this house edge, you would win $4.50 but lose $5. In the long run, you expect to lose $0.50, or 5% of your money."

"Mechanical slot machines have everything you need to known written on the front glass. You can immediately see the type, how much it costs to play, and how much you can win for each combination."

"Casinos never make rule changes that benefit the player; if you see a new rule, it's bad for you. For example, some casinos are starting to pay 6:5 for blackjacks instead of the better 3:2."

"In the early 20th century, slots were made illegal. To get around this, slot machines were made to look like vending machines and players would actually get sticks of gum every time they played."
