"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."

"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."

"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."

"Although all casino games have a built-in house edge, some games rely purely on luck while others allow players to use skill to improve their odds. Try to play these skill-based games more often."

"When playing blackjack with more than two decks, all the players' cards are dealt face-up from a device called a shoe and everyone can see them. Touching your cards is prohibited."
