"The long run, so to speak, is the expected amount that you would win or lose if you played the game long enough to equal an average result. This is expressed as the EV, or expected value."

"When a dealer has an ace as their visible card, they will ask for insurance bets and then check if they have a blackjack. If they do, everyone loses. If not, play continues as normal."

"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."

"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."

"Every reel on a slot machine has a certain number of stops which contain either symbols or nothing. While machines with physical reels usually have 22 stops, virtual slot machines can have hundreds of stops."
