"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."

"In order to keep the house edge, casinos offer games where they win outright more often or they offer games where the player may win more often, but doesn't get paid the true odds."

"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."

"Casinos are pretty predictable, they all have the same colours for the same chips. $1 chips are white or blue, $5 chips are red, $25 are green, $100 are black, $500 are purple, and $1,000 are orange."

"The mathematical probability of something happening is its true odds. Casinos maintain their advantage by paying players less than the true odds of their wins."
