An over/under bet, also known as a totals bet, is a type of wager where bettors predict whether the combined score of two teams in a game will be over or under a line set by the sportsbook. For example, if the over/under for a football game is set at a certain number, bettors can choose to wager on whether the total points scored by both teams will exceed that number (the "over") or fall short of it (the "under"). If the final score matches the line exactly, the bet is typically considered a push, and all wagers are refunded.
