Over Under is a popular betting format often used in sports wagering, where bettors predict whether the total score of a game will be over or under a specified number set by oddsmakers. This format allows for a more engaging experience, as it focuses on the combined performance of both teams rather than just the outcome of the game. It appeals to a wide range of bettors, from casual fans to seasoned gamblers, as it encourages analysis of team statistics, player performance, and game conditions.
