An Over/Under is a wager that predicts the total score of a game. It’s one of the most popular sports betting options, right next to moneylines and point spreads. You can place a bet on the Over/Under in all types of games, but it’s particularly popular in football, basketball and tennis.
A sportsbook sets a number for a game’s total, and bettor’s then wager on whether or not the actual score will fall over or under that total. The over side of the total is denoted by an “O” and the under is indicated by an “U.” Unlike spread bets, however, a bettor must pay vigorish, or juice, on both sides of their wager. This is known as the vig or vigorish margin and helps the bookmaker make money.
When deciding on an Over/Under, consider the overall scoring tendencies of both teams and the match’s context. For example, if the game is being played in a stadium with high winds or cold weather, that may inhibit both team’s offensive efficiency and cause the total to go lower than expected.
Live over/unders are another great opportunity for savvy bettors to look critically at the market and spot trends. If you’re noticing that the line has been moving quickly, for instance, after a few empty possessions by both teams, then you may want to pounce on the over.
