In sports betting, the term "Over/Under" refers to a type of wager where bettors predict whether the total score of a game will be over or under a specified number set by the bookmaker. For example, if the bookmaker sets the total at 50 points, bettors can choose to wager on whether the combined score of both teams will exceed 50 (over) or fall short of it (under). This betting option is popular in various sports, including football, basketball, and hockey. It allows fans to engage with the game beyond just picking a winner, as they can focus on the overall scoring dynamics.
