Gambling regulations in the U.S. and Europe differ significantly in terms of structure and enforcement. In the U.S., gambling is primarily regulated at the state level, meaning that each state can establish its own laws regarding the types of gambling allowed, licensing requirements, and the age of participants, leading to a patchwork of regulations across the country. In contrast, many countries in Europe have more centralized regulatory frameworks, often overseen by national authorities that provide comprehensive licensing and oversight for online and land-based gambling operations.
