Definition of Score on 1st Drive

What does the term "Score on 1st Drive" mean in the world of football betting? What is meant by the "Score on 1st Drive" line?

With the "Score on 1st Drive" lines, you are betting on whether or not a team (or both teams, or neither team) will score on their first drive of the game.

*Note: only offensive scores will count. A defensive score for a team prior to their first offensive drive will not resolve to yes

For instance, the Arizona Cardinals are playing the Buffalo Bills. The "Score on 1st Drive" lines might look like this:

Arizona Cardinals Offensive Score on First Drive, +155
No Offensive Score, -200

Buffalo Bills Offensive Score on First Drive, -120
No Offensive Score, -105

We can also bet on if both teams will score on the first drive on the game, or if both teams WILL NOT score:

Both Teams to Score on Their 1st Drive

Yes, +500
No, -900

So, let's say that you bet on the "Yes" line, as you think that both the Bills and Cardinals will score on the first drive of the game.

The Bills score a field goal and the Cardinals score a touchdown, and the line resolves to YES.

In this case, if you bet $100, you would receive $500 in total profit, as well as your original $100 back bet.
