An “over/under” bet, also known as a “totals” bet, it’s a type of prop bet that allows you to predict whether the total number of a specific statistic will be over or under a predetermined number set by the sportsbook.
For example, let’s say a sportsbook sets the over/under for total touchdowns in a football game at 2.5. If you bet the “over,” you are predicting that the total number of touchdowns scored by both teams will be 3 or more. If you bet the “under,” you are predicting that the total number of touchdowns will be 2 or fewer.
Over/under bets can be placed on a variety of statistics, including points, yards, touchdowns, and more. They are a popular type of prop bet because they offer a relatively simple way to wager on a game.
It’s important to note that the over/under number set by the sportsbook it’s not meant to predict the exact number of touchdowns, points, or yards that will be scored. Instead, it is a way for the sportsbook to even the odds and ensures that there is an equal amount of money bet on the over and under.
To determine the winner of an over/under bet, you need to compare the total number of the chosen statistic to the over/under number. If the total is greater than the over/under, the over bet wins; if the total is less, the under bet wins.
I hope this helps on how over/under prop bets work.
