"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."

"Casinos are pretty predictable, they all have the same colours for the same chips. $1 chips are white or blue, $5 chips are red, $25 are green, $100 are black, $500 are purple, and $1,000 are orange."

"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."

"Slot machines have been around since 1887 when San Francisco inventor Charles Fey built a machine featuring three wheels decorated with symbols like diamonds, hearts, and bells, which triggered the jackpot."

"Nearly all modern slot machines pay out winning combinations that start on the furthest left reel and progress to the right. Keep that in mind when it looks like you won, but didn't get paid."
