The number that comes after the plus or minus sign is how significant of a favorite or underdog the teams are, regarding points. In the first game, the Bengals are a 1.5 point underdog. This means that the sportsbook thinks the Bengals are going to lose the game by 1.5 points. This means, by default, that the Chiefs are a 1.5 point favorite. This means the sportsbook thinks the Chiefs are going to win the game by 1.5 points.
As you can see, the public seems to think that Florida is going to win this game by more than seven points. If the game started now, the sportsbook would stand to lose a lot of money if Florida did in fact win by more than seven points. They would stand to make a lot of money if Florida lost or won by less than seven points. Regardless of how the sportsbook thinks the game will go, they are not in the business of gambling. They want to guarantee profit as often as they can.
We need to figure out how much profit we will get per dollar we are going to bet and then multiply that by how many dollars we are going to bet. If we divide the moneyline number by 100, it will tell us how much profit we will get for every $1 we bet. So, 145/100 = $1.45. For every $1 we wager, we will get paid $1.45 in profit for a correct prediction.
On the other hand, betting which team is going to score first is a bit of a crapshoot. Sure, you could try and predict who has the better chance of winning the opening toss, but even then it’s going to be a bit of a gamble to predict which team scores first. If you’re betting on this bet, you’ll only be guessing, and therefore have no way to exert an edge over your competition.
Overtime and the shoot-out does count for NHL point-spread results in Ontario. Whenever you see a game -0.5 essentially both teams have a spread of -0.5 and your team has to win the game for you to win the bet. Lately there have been more -1.0 / +1.0 NHL spreads in Ontario. If you choose the -1.0 spread and the game goes to overtime you cannot win the bet. You can only push the bet if your team wins in overtime or the shoot-out. Conversely, if you choose the +1.0 spread and the game goes to overtime you cannot lose the bet but will push the bet if your team loses in overtime or the shoot-out.
The first part of each line tells you who you are betting on. The first line is a bet on Mike Tyson and the second line is a bet on Old Man River. Next, you’ll see a plus or a minus sign. The plus sign signifies the fighter who is an underdog, and the minus sign signifies the fighter who is the favorite. As you can see, Mike Tyson is the favorite and Old Man River is the underdog.
The second number in our example (-110 for both teams) tells you how much you have to wager in order to win $100. It’s an easy way to calculate how much you’ll win if your bet pays off, presented in units of $100 at a time for simplicity’s sake. Most of the time, these two numbers will be the same, because oddsmakers want to set lines so that they get as much action on the underdog as on the favorite, guaranteeing them a profit. If a book gets a single bet of $110 (by a customer hoping to win $100) on the Cowboys and a single bet of $110 on the Giants, it will have taken in $220, but will only have to pay back $210 to whichever customer wins the bet. That’s a guaranteed profit of $10, and since sportsbooks take far more than a single bet in either direction, they stand to earn that seemingly small amount of profit many times over. The $10 difference between what you wager and what you win is known as juice or vig in the sports betting industry, and it’s the way books earn their bread and butter.
On the other hand, underdog moneylines can be lucrative wagering opportunities. Upsets happen more often than some of us think and moneyline betting is a great way to take advantage. For example, for a moneyline wager of +250, a bettor will only need to win about 28% of the time to break even and for a +300 wager the bettor would only need to win 25% of the time to break even. If you can spot upsets even decently well, moneyline wagers on underdogs can be profitable bets.
With money line bets the goal is to pick the outright winner of a game or event without the use of a point spread. While money line betting is available for sports where point spreads are used, they’re most popular in sports like baseball and soccer where very few points are scored. Money lines are also used for sports where points do not determine the winner or loser, as in auto racing or tennis.
For example, in a cricket match a sports spread betting firm may list the spread of a team’s predicted runs at 340 – 350. The gambler can elect to ‘buy’ at 350 if they think the team will score more than 350 runs in total, or sell at 340 if they think the team will score less than 340. If the gambler elects to buy at 350 and the team scores 400 runs in total, the gambler will have won 50 unit points multiplied by their initial stake. But if the team only scores 300 runs then the gambler will have lost 50 unit points multiplied by their initial stake.
