"Usually, a roulette table will have two different balls of slightly different sizes. Dealers can choose which to use based on which is more comfortable. The size of the ball does not affect the outcome."

"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."

"You get free drinks when you play in a casino. Casinos do this because alcohol makes you gamble more, of course. If you want to stay in control and have a shot at winning, don't drink."

"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."

"Although all slot machines look alike, no two models of machine are the same. Some are far better than others, and you should learn how to evaluate each machine to see if its worth playing."
