"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."

"The bigger the prize, the less likely you are to win it. One to one bets like in blackjack are the easiest to win, while enormous jackpot games also have an enormous house edge."

"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."

"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."

"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."
