Line

Line in betting refers to the odds or point spread set by a bookmaker for a particular event. It represents the expected margin or total for a game and is used to balance betting action.

For example, in a football match, the bookmaker may set a goal line at 2.5, meaning you can bet on over or under 2.5 goals. In American sports, a point spread line like Team A -3.5 means Team A must win by at least 4 points for the bet to win. Lines can move based on betting activity and new information.
