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.

In Pennsylvania (PA), gaming law is governed by both state statutes and federal law. The Pennsylvania Gaming Control Board (PGCB) is the regulatory body responsible for overseeing all aspects of the state's casino industry, which includes slot machines, table games, and sports wagering. The state has legalized and regulates various forms of gambling, including casinos, horse racing, sports betting, and the state lottery. Online gambling and fantasy sports are also legal in Pennsylvania. The state's gaming laws are detailed in the Pennsylvania Race Horse Development and Gaming Act. Additionally, charitable gaming activities like bingo and raffles are permitted under specific conditions. Federal laws, such as the Illegal Gambling Business Act (18 U.S.C. §1955), also apply and prohibit illegal gambling operations. It's important for entities operating in the gaming industry to comply with both state regulations and federal statutes to ensure their activities are lawful.
