The bulk of these indictments were brought under the federal Illegal Gambling Business Act, which means the business must violate state gaming law, involve five or more people and have operated consistently for more than 30 days or gross more than $2,000 in a single day. It is generally illegal to run a for-profit casino or own a functioning slot machine that is less than 25 years old. Gambling is a tightly regulated industry in California and is limited to licensed horse wagering, tribal casinos, state lotteries and cardrooms.
