Definition of Total Rounds

What does the term "total rounds" mean in the world of boxing or mixed martial arts betting? What is a "Total Rounds" line?

In boxing or mixed martial arts, the "total rounds" line is used when you want to bet on how long a fight will last.

Let's take a five-round UFC title fight.

The Total Rounds lines might look like this:

1.5 Rounds

Over, -275
Under, +225

2.5 Rounds

Over, -195
Under, +150

3.5 Rounds

Over, -110
Under -110

4.5 Rounds

Over, +165
Under, -185

So, let's say that you believe that this fight will end early - let's say in the first round.

In this case, you'd want to bet the Under 1.5 rounds, which would pay you a very nice $225 in profit for every $100 bet.
