State-by-State Casino Age Limits

Let’s take a closer look at the most common scenarios when asking how old do you have to be to be in a casino.

States Where the Casino Age Is 21

States Where the Casino Age Is 18

There are exceptions. In states such as Oklahoma, California (tribal casinos), Michigan, and Minnesota, you can enter and gamble at 18. However, many of these casinos do not serve alcohol, or they restrict alcohol to separate bars. So if you ask how old do you have to be to get into a casino on tribal land, the answer is often 18.
