An "over/under bet" is a type of wager commonly used in sports betting. In this bet, a sportsbook sets a predicted total score for a game, and bettors can wager on whether the actual score will be over or under that number. For example, if the total is set at 50 points, you can bet on whether the combined score of both teams will exceed 50 (over) or fall short (under). This betting option is popular because it allows fans to engage with the game beyond just picking a winner. It can apply to various sports, including football, basketball, and hockey, making it a versatile choice for bettors.
