"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."

"Nearly every casino game in the world has an EV under zero, which means that the house has an edge over the player. You might win occasionally, but in the long run you will lose."

"The lights on the top of slot machines aren't just for decoration. Called 'candles', the colour of the bottom light denotes the machine's denomination: nickels yellow, quarters yellow, and dollars blue."

"Casino results are expressed as probabilities, usually as a decimal amount between zero and one where zero is impossible and one always happens. For example, the chance of a flipped coin being tails is 0.5."

"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."
