Over/Under, also known as totals betting, is a sportsbook market where players wager on whether the total number of goals, points, runs, or other statistics in an event will finish over or under a line set by the bookmaker. For example, in a football match with an Over/Under line of 2.5 goals, bettors choose whether the match will have more or fewer than three total goals. Over/Under betting is one of the most popular markets in sports betting.
