The reason why you will typically see a (-110) line next to a point spread is simple. This is the commision in which the sportsbooks charge for you to place your wager. This is how the casino makes their money. Think of it as a commission. You make a bet, they charge 10% for you to do so. Bookmakers call this “Vigorous or Vig” it’s also known as the “Joice”
For each NFL game the oddsmakers set a number of points in which the favored team is favored by. Bettors can then either choose for the favored team to win by more than the number of points set, or bet on the underdogs to lose by less than the number of points they are underdogs by or win the game straight up. For example, the spread could be set on the favored team at 6.5 points. This would mean in order for a bet on the favored team on the spread to win they would need to win by more than 6.5 points (7 or more) in order to win the bet. It also means that a bet on the underdog team would win if the underdogs lost by less than 6.5 points (6 or less) or won the game outright.
Here in this point spread example for the NFL, the Falcons are playing the Panthers. Atlanta has been set as a three-point favorite on the betting line. That means that for Atlanta to cover the spread that has been set, they will need to win by at least four points. And for Carolina to cover the point spread, they can do so with a loss by two points or less, or obviously a win straight up. If the Falcons win by exactly three points, the bet would result in a push with no payouts.
In most football games there is a favorite and an underdog. Very occasionally there are games where the two team are completely evenly matched, but for the most part one team is favored over the other to win. With point spreads, the idea is to create an even money proposition when betting on the game. So the favorite has to win by at least a certain number of points for a wager on them to be successful, and the underdog has to lose by no more than a certain number of points for a wager on them to be successful. The bigger the gap in quality between the two teams, the bigger the point spread.
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.
Where people seem to get confused with moneyline bets is with how they are presented and how they pay out. While the criteria to win a moneyline bet will never change, the amount you win and how the bet is presented will change. Don’t worry, though. It’s easy to understand if it’s presented to you properly. We are going to cover this thoroughly in the coming sections. You’ll be a moneyline expert ready to crush the books when you get done with this guide.
As we did with the underdogs, we need to figure out how much we will profit for each $1 that we wager. For underdogs, we divided the moneyline number by 100. For favorites, it is the exact opposite. We will take 100 and divide it by the money line number. So, for this example, we will take 100 and divide by 155 and get about $0.645 or about $0.65 in profit for every dollar that we bet.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value. The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
