Gamblers in California must be a minimum of 18 years old. If however, alcohol is served there, the age is 21 and beyond. Also check out this site: California Casinos which has a clean interface and pulls information from various sources.
In some cases, one will allow gamblers to begin at a younger age than the other. In the event that these ages differ from one another, you have to go with the gambling age that is higher. For instance - your casino allows 18 year olds, but your state requires you to be 21. That means you cannot join unless you are 21, as per your state's regulations.
