"Nowadays, most slot machines have multiple pay lines. You choose how many lines to play and how much to bet on each, but you must bet at least one coin on each line to activate it or winning that line won't count."

"Casinos are specifically laid out to be disorienting and make you get lost so you keep playing. When you first walk in, pick a good landmark which can help you find the exit again."

"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."

"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."

"Playing at a full roulette table is far better than playing at an empty one because it reduces the number of spins you see per hour while qualifying you for better comps through longer play."
