Action in the context of gambling refers to the total amount of money a player wagers during a single playing session in a casino. It’s a broad term that encompasses all types of bets a player makes, whether on slot machines, table games, or other gambling activities. Casinos often track a player’s actions to determine their eligibility for various comps and rewards. The term is important because it not only indicates a player’s level of engagement with the games but also helps the casino assess the player’s overall betting behavior and potential value to the facility.
