If you bet on soccer, you have likely see your sports book offering odds on a "double result".
What is a "double result"?
Let's say that Swansea is playing Southampton. There are nine different "double result" lines. Here is one:Draw/Swansea - 6.00
In a "double result", you are looking to correctly bet on the outcome after half-time and the outcome after full-time.
So, in the example listed above, if the game was tied at half-time but Swansea ended up winning, this line would end up paying out.
You need to get the result after half-time AND the result after full-time correct in order to win the bet.
Let's look at a second example from the same game:
Southampton/Swansea - 26.00
In this example, Southampton would need to be leading after the first half while Swansea would need to be winning at full-time. This is fairly unlikely to happen, which is why you would get odds of 26.00.
