What is the over-under number called?

When looking at listed odds for a game, this is represented as total, over/under, and sometimes shortened as O/U. There will be a number listed, something like 155 for a college basketball game, 8 for a baseball game, or 47 for an NFL game. That number is the line for over/under bets, called the total.

What happens if the over-under is exact?

The bet is called a push if the actual number exactly equals the over-under, in which case all bets are refunded.

How do you calculate over-under?

If the sportsbook set the score to 110, for example, an “Over” bet would win if the final score is 111 or more. Conversely, an “Under” bet would win if the final score is 109 or less.
