Over the past four years, sports betting has emerged from the shadows and into the mainstream. The anti-gambling stigma that existed for decades faded quickly in American popular culture, opening the door for a massive, multibillion-dollar legal sports betting industry to emerge.

With sports betting now legal in many states, millions of sports fans will be looking to enter the betting market for the first time.

But where do you begin if you’re unfamiliar with the terminology?

Here’s an introduction into how to bet on sports with 12 things that every beginner needs to know.

1. Favorites vs. Underdogs

When oddsmakers release a betting line on a game, the first thing they do is decide which team should be the favorite and which should be the underdog.

The favorite is the team that is more likely to win the game and will get a minus sign next to its odds. The underdog is expected to lose and gets a plus sign.

Here’s how it looks at FanDuel.

If the game is a true 50/50 toss-up, books will open it as a “pick” or “pick’em.”

2. Spreads

There are two main ways to bet on a favorite or an underdog. The first is the point spread, which is a bet on the margin of victory.

Let’s use the same example from FanDuel.

point spread example fanduel nfl

The Eagles are a -4.5 favorite over the Lions in Week 1. That means anyone betting on Philadelphia needs the Eagles to win by 5 or more points. Anyone betting on Detroit needs the Lions to lose by 1-4 points or win the game.

  • Eagles win by 7: Eagles bettors win
  • Eagles win by 3: Lions bettors win
  • Lions win by 3: Lions bettors win

Point spreads are adjusted for team ability and many other factors. That’s why the Colts are an 8-point favorite on the road against the lowly Texans, while the Eagles are a smaller favorite on the road against the Lions.

Spreads are available in every sport but most common in higher-scoring sports like basketball and football.

3. Moneylines

The second way to bet on a favorite or an underdog is on the moneyline. A moneyline bet requires you to just pick the winner of the game, and uses American odds to calculate the payout.

American odds are centered around winning $100.

So if you’re betting a -200 favorite, you need to risk $200 to win $100, or any fraction of that — $20 to win $10, $2 to win $1, etc.

If you’re betting a +200 underdog, you will win 2x your money for every dollar wagered — $100 to win $200, $10 to win $20, $1 to win $2, etc.

Back to Colts-Texans. Oddsmakers believe Indianapolis is the much stronger team. So to bet the Colts just to win the game, you need to risk a substantial amount.

The Colts are -375 — that means you need to risk $375 to win $100 or $37.50 to win $10.

The Texans are +300. If you bet $100, you’ll win $300. Or if you bet $5, you’ll win $15.

So why do you have to risk more on the favorite than you’d win on the underdog?

This is called the juice, and it’s how sportsbooks maintain their edge over bettors.

Moneylines are available for all sports, but they are predominantly used when betting on lower-scoring sports like baseball, hockey and soccer.

4. Over/Unders (Totals)

In addition to setting a line for the favorite and the underdog, oddsmakers will also set a total number of points scored in a game by both teams combined. This is called the total or over/under.

Bettors can then wager on whether or not the game will go over or under the total. You’re not trying to guess the exact score (though that bet is available, too).

Eagles-Lions has a total of 46 — about average for an NFL game.

  • If you bet the over, you need 47+ points
  • If you bet the under, you need 45 points or fewer
  • If it lands on 46 exactly, it’s a push and bets are refunded

over under example fanduel

The over/under concept is applied to many different kinds of bets.

  • Tom Brady over or under 295.5 passing yards
  • LeBron James over 7.5 assists
  • Yankees over 93.5 wins

5. What Is the -110 Number Listed Next to My Bet? 

With many bets, you may see two numbers — a spread like -4.5, and then odds below it, like -110.

  • The spread is the margin of victory your team needs to win by
  • The -110 odds are the price you need to pay to bet that spread

juice example in sports betting

Let’s say you’re betting on the Colts at DraftKings.

  • The spread is -8, so to win your bet, you need Indy to win by 9+ points.
  • The “juice” is -110. So you’d need to wager $110 to win $100, or $11 to win $10, on that spread.

If you wager $11 to win $10 and the Colts win by 14, you’d win $10. If the Colts win by 3, you’d lose $11.

NFL spreads will usually be -110 on both sides.

But for something like an MLB spread, where the line is almost always -1.5 for the favorite and +1.5 for the underdog, the juice will differ depending on the gap in ability between the two teams.

6. How to Place a Bet

OK, so you now know what each bet means. So how do you place them?

Most sportsbooks make it quite easy.

  • Navigate to your desired game and bet type
  • Click the “bet cell”
  • The bet will populate in your bet slip
  • Enter your bet amount
  • Submit bet

 

Each team will be lined up with its corresponding lines. So in that video, USC was a 14-point underdog against Alabama. To bet USC, just click the cell across from its name.

7. Where to Place a Bet: Best Online Sportsbooks

So where can you actually place a bet?

More than half the U.S. states have some form of legal betting, but about 20 have full online wagering. Others have only in-person betting at casinos, racetracks and other venues.

8. How Much to Bet

In the end, you have the final say on how much to risk on a game, but a good rule is risk only what you can afford to lose. Sports betting is a marathon, not a sprint. There will be good days and bad days. As a result, we recommend a flat-betting approach.

This means betting the same amount on every game and risking only 1% to 5% of your bankroll per play (the bankroll is the starting amount you have at your disposal to bet with). For example, if you are starting with a bankroll of $100, you should risk no more than $5 per game.

By employing a flat-betting approach, bettors guard themselves against losing their entire bankroll during a bad stretch, but also set themselves up for a positive return on investment (ROI) when they’re doing well.

9. Parlays

A parlay is a wager type in which two or more bets are linked together to create one bet with a greater payout, but all the bets must win.

So instead of betting $10 each on three games, you can make one $10 wager that will pay out more of all three teams win. But if even one loses, you lose your $10.

The payouts will vary based on how many bets you include, and the prices of those bets.

This MLB parlay with Mariners +114, Mets -220 and Marlins and Marlins -134 pays +443.

parlay example fanduel

Even more popular than traditional parlays featuring multiple games is the same game parlay, pioneered by FanDuel and now offered by almost every sportsbook.

This feature allows you to parlay multiple bets from the same game, with the correlation of each event priced in. That means if you bet over 51 in Rams-Bengals and Matthew Stafford over 2.5 passing touchdowns, you won’t get the full parlay payout, because those events are more likely to happen together.

Same game parlays wildly popular in standalone NFL and NBA games.

10. Props

Betting spreads and totals isn’t enough for most people anymore.

Props — short for proposition bets — can be any wager that’s not a standard point spread, moneyline or total.

But when people refer to props, they’re usually talking about player props like:

  • Steph Curry over or under 5.5 assists
  • Max Scherzer over or under 7.5 strikeouts
  • Derrick Henry to score the first TD +500

Like point spreads, you often have to pay the corresponding price with props.

Here, Scherzer’s strikeout total against the Reds is set at 7.5. But it’s more likely than not he goes under, according to FanDuel’s lines, so you have to pay a steeper price to bet the under than the over.

player prop example max scherzer

If you’re getting serious about making money betting sports, props are a great place to start.

U.S. sportsbooks offer hundreds of props on every game, creating a greater attack surface since they can’t properly price all of them. Even if you’re not creating your own statistical models, tracking specific props and understanding how they’re priced can help give you an edge over the sportsbooks.

11. Shop for the Best Line

Lines can vary based on the sportsbook, because different books have different clienteles. As a result, one book may post the Cavs -8 while another has -7.5.

Having access to more than one sportsbook allows you to shop for the best line. Getting an extra half-point might not seem like a huge deal, but it adds up over the long haul and increases your chances of winning.

Our live odds pages will automatically surface the best line for every game.
