Gaming law is generally the law that applies to the gaming or gambling industry, including casinos, lotteries, horse racing, dog racing, sports betting, card games, table games, social gambling, bingo, raffles, slot machines, scratch tickets, etc. Gaming law includes state and federal statutes, rules, and regulations—and legal principles from traditional areas of law, such as contract law, administrative law, constitutional law, criminal law, and regulatory law. For example, the federal statute prohibiting illegal gambling businesses is located at 18 U.S.C. §1955.
