"When a dealer has an ace as their visible card, they will ask for insurance bets and then check if they have a blackjack. If they do, everyone loses. If not, play continues as normal."

"Blackjack tables are felt-covered half circles with room for seven players. Each player has a box or circle in front of them where they put their bet while other chips outside are not in play."

"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."

"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."
