"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."

"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."

"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."

"While mechanical reels remain limited to 22 physical stops, today's video slot machines use virtual reels which can carry dozens of video symbols and hundreds of stops, allowing casinos to offer enormous jackpots."

"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."
