"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."

"If you turn over a playing card, the chance it will be red is 0.5, or 50%. If the casino was fair, it would pay you $1 for a $1 bet. But if a casino pays you $0.90 instead, it has a 5% edge."

"Nowadays, most slot machines have multiple pay lines. You choose how many lines to play and how much to bet on each, but you must bet at least one coin on each line to activate it or winning that line won't count."

"Casinos are specifically laid out to be disorienting and make you get lost so you keep playing. When you first walk in, pick a good landmark which can help you find the exit again."

"You win in blackjack when the sum of your cards equals twenty-one or less and you beat the dealer. You beat the dealer when you have a higher hand or the dealer goes over twenty-one."
