Do you need a Driver's license to gamble at a casino?

Didn't see a specific law concerning this. However, you must be 18 for parimutuel betting and 21 for casino gambling.

Since it is against the law for operators of those establishments to allow anyone underage to gamble, they can require you to show a photo ID (does not have to be a driver's license) to prove your age before allowing you admittance.
