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.
Anyone planning to visit a casino should note that although you only need to be 18 to gamble, you must be 21 years old in order to enter a bar. Many of the casinos are also bars which serve alcohol throughout, and as such minors will not be allowed in.
