Money Lines
Money Lines are used to some degree in most major Sports. In a money-line bet you are wagering on the outright winner of the contest independent of any point-spread. For every money line there is one number for each of the two sides of the play, the underdog and the favorite. An example of a money-line in football is:
| Colts | -140 |
| Dolphins | +120 |
In this example the favorite is denoted by the minus sign and the underdog by the plus sign. You would wager $140 to win $100 on the Colts (the favorite) and you would wager $100 to win $120 on the Dolphins (the underdog). Because no point-spread is used to determine the winner you must risk more money to win less on the favorite and vice-versa on the underdog.
