If you like favorites, you're going to be betting a lot to win a little. The money line will always be listed to the right of the point spread on the odds board in a sports book. In the above example, the money line would probably be Chicago -250 and Detroit +200. To bet Chicago simply to win, you must wager $250 to win $100, while a $100 bet on Detroit would pay $200 if the Lions come through.
For example: New England –2.5 (–110) or Philadelphia +2.5 (–110) means you’d wager $110 for the chance to win an additional $100 if you bet on the point spread. Depending on which side is receiving the most action, a sportsbook will often move the line up or down in order to incentivize betting on the less popular side. Injuries or unforeseen changes can also impact a point spread gambling line. Point spreads are often listed with a half-point (ex: 2.5) in order to prevent the final margin from landing exactly on the point spread (ex: 10-point spread, final score of 20–10). A “push” or “tie” usually goes to the house or sportsbook, unless another arrangement has been agreed upon beforehand.

If you see the point spread move, let’s say from -9 on Tuesday to -10.5 on Friday, this is known as a line move. It occurs when there is a surplus of bettors wagering on the same side of the game and sportsbooks move the line to balance the action. That means encouraging more people to bet the other way by making the line more appealing. This reduces risk for the sportsbook, who wants to have an equal handle on each team.
The spread - The point spread is used in high-scoring sports like football and basketball. It is basically a handicap used to make all games competitive in the eyes of bettors. The spread gives one team an advantage of a few points. Standard notation for the point spread shows the favored team first, followed by a negative number (the actual spread). The home team is shown in capital letters. So if Buffalo was playing against Green Bay in Green Bay, and they were favored to win by seven points, it would look like this:
Total: Also called the over/under, it is a number set by the sportsbooks that proposes a number of points that will be scored in the game by both teams combined. Then, fans predict whether there will be more points or less points than the ‘total.’ If you bet the under 41.5, you are hoping for a tough defensive battle with lots of running game. Pick the over, and presumably you feel this will be a high-scoring game. In short, you are predicting whether the combined total score will be more than (over) or less than (under) the total.
