In sports betting, an over-under bet, also known as a total bet, is a wager on whether a specific statistic for a game will be higher or lower than a pre-agreed value. The most common type of over-under bet is on the combined score of two teams in a match. For example, if the over-under for a basketball game is set at 215, a bet on the over means you think both teams will combine to score more than 215 points, while a bet on the under means you think they will score less than 215 points. Over-under bets are popular with people who are new to sports gambling because they work in a simple way.

Here are some key points to keep in mind about over-under bets:

• Over-under bets are among the most popular wagering options in sports betting, behind point spreads and moneyline bets.
• Over-under bets can be placed on a variety of statistics, including the combined score of two teams, the total number of points scored by a player, or the total number of home runs hit in a baseball game.
• The payout on an over-under bet doesn’t just depend on predicting the score correctly. The odds will also tell you how much the sportsbook will take out of your winnings.
• Most over-under bets have a vig of -110 on both the over and under, meaning that for every $100 you wish to win, you must wager $110.
• Over-under bets are accompanied by odds, just like spreads, and are usually at or around -110.

Overall, over-under bets are a simple and popular way to bet on sports, and they can be placed on a variety of statistics.
