When betting on the underdog, the first step is the same. Divide the positive moneyline by 100, which in the case of the Grizzlies in the above example would give you 2.10. Then, multiply your stake by that number to get your potential winnings. $450 multiplied by 2.10 is $945. Essentially, this means if you risked $450 on the Grizzlies, you would stand to win $945.
If you bet $100 on the Magic, you would get $105 in return. If you bet $100 on the Mavericks, you would get $90.91 in return. You might be asking yourself why they aren’t paying out the same amount on both sides of the game. The reason is that the difference is the house rake. Sometimes referred to as the vig or the juice, this is the small percentage that the sportsbook takes off the top for facilitating the action. The percentage that the house takes will vary, and different sides of the bet will pay for it.
One of the most basic concepts when it comes to betting on sports, especially football and basketball is the pointspread. Even people that do not bet on sports understand what it means when they read or hear that New England is a seven-point favorite against Miami. While reading a pointspread and understanding what they mean is a very basic sports betting concept, there is still more to these numbers than meets the eye.
Essentially, a moneyline bet is a bet on which team is going to win the game. There is no point spread or other handicap for either team, so if you pick a team and it scores more points than the other team then you win. Obviously there has to be a catch, though, or the bet would be way too simple. The sportsbooks balance their risk by setting different prices on each team. You win a smaller amount than you bet if you pick the favorite, and you generally win more than you bet if you pick the underdog. The stronger the favorite the less you will win, and vice versa.

If bettors were quick to jump on the Atlanta line at +4.5 when it first came out, they would have a distinct advantage over those who waited closer to kick off and were stuck with +2.5. The opposite holds true for Carolina. Bettors that were quick to pull the trigger are now laying two more points than they would if they were patient and saw the line movement before making their move.
If you wager $100 cash on odds of +100, you are staking $100 cash to win $100 cash. Your total potential return is $200, which is your initial stake plus your winnings. If you wager $100 free play on +100, however, your total potential return is just the $100 winnings. Whether you win or lose, your free play is used up. Obviously, free play bonuses aren't worth as much as cash bonuses, so that means it's up to you to squeeze as much value out of them as possible.
This used to be impossible or extremely time-consuming when only land based sportsbooks and casinos existed. You would have to drive hundreds of miles if you wanted to get to another casino and then hope they still had the different line. This would cost you travel money as well as time. Online sportsbooks make this extremely easy now. You can check several sportsbooks lines on a game within a matter of seconds or minutes. It doesn't cost you any additional money, just a few minutes of your time and can have a huge impact on the outcome of your bets.
The sportsbook will sometimes move this line if they need to encourage more bets on one side of the game. Their end goal is to have the same amount of money bet on both sides of the game so that no matter who wins, they make money. For as much as they love to facilitate gambling and betting, they don’t like to leave things to chance for themselves.
Above, you can see several numbers to the right of both teams. These all represent the different lines that are available on the San Francisco vs. Los Angeles game. The first set of numbers for both teams is the point spread, the second set is the moneyline, and the third set is the over/under (a.k.a. totals). We'll explain each of these lines more in-depth below.

"Draw No Bet" is where it is possible to bet on either the home team or the away team. It is also common practice to refer to "Draw No Bet" in cases where no draw odds are offered. Should the specific match contain no winner (e.g. match ends as a draw), or the particular occurrence not happen (e.g. First Goal, Draw No Bet and match ends 0-0) the stakes will be refunded.
The secret to winning sports bets is finding value and picking winners. There is absolutely zero correlation between the complexity of a bet and how likely you are to win. In fact, you could say that there is a negative correlation because a lot of bettors don’t fully understand the complex bets they are making, meaning they are more likely to make mistakes and incorrectly assess value.
Remember, these calculations are for your profit. Profit is different than the total money returned that you will get from the sportsbook. If you correctly bet the Falcons to win, the sportsbook will return you $340. This will be your $240 in profit as well as your $100 bet that you made. Make sure that you pay attention to this when working with these numbers because we see people get confused all the time as different sportsbooks will give you different numbers.
You'll also usually be given the option to wager on the game with the money line in football and basketball. In this case, all you have to do is pick the winner of the contest, but there's one drawback. If you bet on the team that's expected to win, you can find yourself risking much more money than you stand to win. Each team is assigned odds, much like in a horse race where a 2-1 favorite will pay out much less than a 15-1 longshot. This method also evens the playing field for bookies, sportsbooks and other gambling institutions.
A point spread in sports is a figure set by oddsmakers to provide an advantage or disadvantage based on the margin of victory or defeat for a given team. The “favorite” team (labeled with a “-” sign) would be at the disadvantage as they would need to win the game by a set number of points while the “underdog” team (labeled with a “+” sign) would be given an advantage to not lose the game by a set number of points. The reason oddsmakers do this is to provide betting interest for both sides due to one team typically being better than the other.
