"Every reel on a slot machine has a certain number of stops which contain either symbols or nothing. While machines with physical reels usually have 22 stops, virtual slot machines can have hundreds of stops."

"If you turn over a playing card, the chance it will be red is 0.5, or 50%. If the casino was fair, it would pay you $1 for a $1 bet. But if a casino pays you $0.90 instead, it has a 5% edge."

"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."

"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."

"Mechanical slot machines have everything you need to known written on the front glass. You can immediately see the type, how much it costs to play, and how much you can win for each combination."
