Defining plus and minus, one of the most common gambling phrases. What does 'plus' and 'minus' mean as a sports betting term? Odds expressed in terms of money, with $100 being the standard. In American sports betting, the industry standard is the use of the plus sign and the minus sign. These signs can tell a bettor a lot about the outcome of their bet, but that's just a little teaser. There's way more to take into consideration as a sports bettor. Feb 04, 2021 American odds, also known as money line odds, indicate return relative to a hundred unit base figure. So whenever there is a minus (-) figure you lay that amount to win a hundred dollars, and where there is a plus (+) you win that amount for every hundred dollars you bet. Let’s take a look at an example.

Learning how sports betting odds work can be intimidating at first, but our guide will teach you how to read odds in no time! This primer is designed for beginners who are curious about common wagering practices and terms.

For starters, you will need somewhere to place bets. If you are in Vegas, great! You can bet at one of the sportsbooks in their casinos. As more and more states pass laws to legalize sports betting, you will also be able to place wagers at local casinos in your area. You could also find a local bookie to bet through, but we recommend betting online.

Las Vegas Sports Betting at the Ticket Window

Betting sports in Vegas is likely going to be the option with the biggest learning curve. You will understand the odds after reading this article, but there are a few other rules and common practices you want to be familiar with that are specific to Vegas.

Many books now offer their own betting apps that make this process a little bit easier, however, the drawbacks are that you must make a deposit upfront for how much you want to bet with, plus you don’t get free drink tickets when you place bets on the app. We’ll step through how you would place a bet in person at the ticket window.

Step-by-Step Guide to Placing Sports Wagers in Vegas

“I’ll take number 403, Cowboys -8, for $110 straight up.”

1. Use the rotation number/numbers and the name of the team/teams you want to bet on. The rotation number appears to the left of each team (see image above) and is used as a unique identifier so that there is no confusion about what you want.
2. State the amount you would like to bet. This is how much you are wagering, not how much you want to win. Most books use -110 odds (more on this later), so if you want to win $100, you’d state $110 as your wager amount.
3. Indicate the type of bet you are placing. For individual bets, just say “straight” or “straight up”, otherwise you will need to explain that you are taking a parlay or some other bet type.
4. Repeat as necessary.

How to Read Sports Betting Lines

There are nearly infinite ways to bet sports. If you can think of something to bet on, there is a good chance you can find somewhere to bet on it. What we are going to focus on is the most common types of wagers: point spreads, over/unders (totals), and money lines.

What Does the Plus (+) and Minus (-) Mean in Sports Betting?

One of the first and most important aspects of sports betting every new player must learn is what the different symbols mean. A plus or a minus can mean different things in different situations. They are used for both point spread and money line betting, as well as for the price/juice of each bet.

This is explained in more detail below, but the most important thing to be aware of is that negative numbers represent favorites, while positive numbers represent underdogs. The same is true whether you are looking at a spread or a moneyline, but how these numbers are used is very different. You also need to know that prices on spreads/totals do not impact who/what is favored, it is used to determine how much the bet pays out. Read on for the complete explanation of each of these concepts.

Point Spreads Explained

The point spread is the projected number of points that separate two teams. A game with a spread will have a favorite (the team expected to win) and an underdog (the team expected to lose). A favorite “gives” points and is identified with a minus sign next to their point spread. The underdog “gets” points and is identified with a plus sign next to their point spread.

In the example above, the point spread is 7 points. Patriots are favored by 7 points against the Jets.

If you bet on the Jets +7, they must either win the game outright or lose by 6 points or less. If they lose by exactly 7 points, the bet is considered a push and is canceled.

If you bet on the Patriots -7, they must win the game outright by more than 7 points. If they win by exactly 7 points, it’s a push.

Bet Prices: What Does -110 Mean? If I Bet $100, What do I Win?

The 3-digit numbers to the far right are the listed prices for these bets. This is also called the odds, vig, or juice. An easy way to think of it is the amount you must risk to win $100 on this wager. In our example, -110 means you must risk $110 if you want to win $100. -110 is pretty standard, but you will find different options. We will cover those in more depth when we talk about money lines. The price of the bet has no impact on which team is favored. Only the plus or minus on the point spread matters. This is handled differently when you bet strictly on the moneyline.

What is the Money Line? (How Moneyline Betting Works)

A moneyline bet is on a team to win the game outright (without a point spread) at an adjusted cost. Just like with point spread betting, the favorite will have negative odds, while the underdog will have positive odds. The difference here is in the price or payout depending on which team you take.

A favorite (e.g. Patriots -280) on the money line works just like our bet price example above. In our new example, the Patriots are listed at -280, meaning you would need to risk $280 for a return of $100 on them. It follows that a winning bet on the Pats pays $100 (plus your initial investment of $280 back). This added risk is why betting the spread is usually more popular, especially on favorites.

Sports Betting

Underdogs (e.g. Jets +240) work a bit differently. Instead showing how much you need to risk to win $100, this line tells you how much you stand to win on a $100 wager. That means if you bet $100 on the Jets, and they win, you would win $240. If the Jets lose, you are only out your original $100 wager.

Totals: What Over/Under Means in Sports Betting

The terms “total” and “over/under” are synonymous when placing wagers. This type of bet is on the sum of the points scored by both teams in a game. The bookie sets the number for the total, then you predict whether they will score more or less points than the set number.

The over/under in this example has been set at 42.5. If you project the Jets and Patriots to combine to score more than 42.5 points, you would place a wager on the over. If you think they will score less than 42.5 points, you would bet the under. Let’s say the final score of this game is Patriots 27, Jets 24. Which bet would lose and which bet would win? The sum of all points scored is 27 + 24 = 51, so an over bet wins and an under bet loses.

Sports Betting Plus Minus

You may also note the bet price is not -110 like we have seen before. It is common practice by sportsbooks to adjust prices on or around key numbers for spreads and totals, especially in football.
