A "Cash Game" is a type of poker game where players can buy in for a certain amount of money and play with real cash. Unlike tournaments, players can leave the game at any time, taking their chips and winnings with them. The chips represent real money, and the stakes can vary based on the table limits. In a cash game, each hand is played for money, and players can win or lose based on their performance in that specific session. This format is popular in various poker variants, including Texas Hold'em and Omaha, allowing for a more flexible and casual gaming experience.
