<human>: I've never been to a casino before. What are the rules for gambling at a casino?
<bot>: The rules for gambling at a casino vary depending on the game, but generally speaking, you must be 21 years old or older and have identification that shows your legal age. You will also need to provide valid forms of payment (cash, check, credit cards) in order to participate in any games. Additionally, some games may require an additional fee or deposit before play can begin.
