Money line bets are a popular way to place bets on sporting events. Instead of betting on the point spread, which is how many points a team will win or lose by, a money line bet is simply betting on which team will win the game.
For example, let's say the Los Angeles Lakers are playing the Boston Celtics in a basketball game. The point spread might be something like Lakers +3 and Celtics -3, which means that if you bet on the Lakers, they must win by more than 3 points for you to win your bet. If you bet on the Celtics, they must either win the game or lose by less than 3 points for you to win your bet.
With a money line bet, however, you are simply betting on which team will win the game. The odds for each team will be represented by a number, with a positive number indicating the amount of money you will win if you bet $100 on that team, and a negative number indicating the amount of money you need to bet in order to win $100.
For example, if the money line odds for the Lakers are +150 and the odds for the Celtics are -200, it means that if you bet $100 on the Lakers and they win, you will win $150 (in addition to your original $100 bet). If you bet $100 on the Celtics and they win, you will win $50 (since you are betting $200 to win $100).
The benefit of money line bets is that they are relatively simple to understand, and they offer a way to bet on a team to win without having to worry about the point spread. This can be especially useful if you have a strong feeling about which team will win, but you are not confident about their ability to cover the point spread.
