"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."

"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."

"Although roulette has a relatively high house edge, you can play for longer because an average table only sees about thirty spins an hour, compared to sixty games an hour for blackjack."

"Modern video keno can trace its roots all the way back to ancient China, where a lottery-style game called 'white dove' was used to finance the army during times of war and hardship."

"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."
