There are several ways to bet on over under, but the most common is simply picking the number of points scored over or under a certain number. Bettors can also pick how many points they think will be there by the end of the game. They can predict what payouts they will receive when the actual score comes out. Some over-under bets are also based on the spread or the number of points they favor on a team to win. In this case, the payout is usually adjusted to account for the risk involved in betting on a particular side. Regardless of how it's wagered, over-under bets can be a fun and exciting way to add some extra excitement to a game.
