HB 2996 revises definitions related to gambling offenses in the Texas Penal Code and modifies the legal defense for individuals accused of illegal gambling. It clarifies that "economic benefit" in gambling-related laws refers only to direct winnings from a game of skill or luck, excluding any benefit received before a game starts or after winnings are paid. Additionally, it updates the definition of "private place" to specify that a location requiring membership, invitation, or permission is not considered public, thus exempting certain gambling activities from prosecution. The bill also modifies the defense against gambling charges by removing the requirement for defendants to prove that no one received an economic benefit beyond personal winnings.
