Parlay betting is one of the most popular bet types in the United States. It’s one of few bets that allow you to be creative in terms of controlling the selections you include and the odds you want to receive from that bet.

The caveat of the parlay bet is that they are notoriously hard to win. In this guide, we’re going to look at how parlay betting works, what you need to know about the structure of the bet, and include tips and strategies to enable you to become more profitable from this bet type.

What is a Parlay Bet?

A parlay bet is sometimes known as a multi or combo bet where you include two or more selections to create a single bet. The basis of this market is that you need all the selections to win for the bet to be successful. If just one selection loses, then the entire parlay bet loses.

This type of bet is popular as it allows players to be creative about what selections they want to include and to determine the overall payout of the bet. The more picks that are in parlay wagers on the best online sportsbooks, then the higher the odds will be.

It’s possible to create a parlay bet across multiple sports and markets. For example, you could have a single parlay that would cover moneyline bets in the NBA, NHL, MLB, and NFL. Alternatively, you can include picks from an NFL game week.

The only limitations come with correlated markets. This is where two or more selections are dependent on each other, meaning that the result of one, would affect the odds of the other. We talk in-depth about this and the best parlay bets later in the article.

How Does a Parlay Bet Work?

A parlay starts with choosing the sportsbook you want to place the bet on. You’re looking for the best odds possible, as this can impact the potential payout massively with these bet types. Any betting sites from our top 10 list (above) will be solid choices.

The bet needs to include two or more selections to become a parlay. There are no limits on the number of parlay picks you can include and the more that are included, the higher the odds will be.

Your bet is classed a single wager. Even though it includes multiple selections, you need all these selections to win for your bet to pay out.

Parlay bet

Let’s look at the three-team parlay that we’ve included above which has three picks; Washington, Pittsburgh and Baltimore all to win their upcoming MLB games on the moneyline.

As you can see, the bet slip is going to show us the payout (at the bottom) for the stake that we’ve entered. In this case, it’s a $56.34 return for a $10 stake. We need all of these selections to win for this parlay to pay out.

Parlay Odds – How they are Calculated

Most US sportsbooks are going to provide their odds in an American format by default. This is represented as two numbers, with one being positive and the other negative.

The positive number is the amount of money you will win for every $100 wagered. So, odds of +400 on an NHL matchup mean that if you staked $100, you would get $400 back plus your original stake of $100.

The negative number is the amount you need to wager to make $100 of profit. So, odds of -125 mean that you need to wager $125 to make a $100 profit.

To determine parlay odds the best strategy to work it out is to switch the odds from American to Decimal (European). The reason for this is that the odds are simply multiplied by each other to get the final price and thus work out potential winnings. With American odds to do this without a calculator is almost impossible, but with decimals, it’s much easier, if only to get a ballpark figure.

The example above highlights a four-team parlay and with it, we’ve selected decimal odds to get a better look at how they are calculated.

What parlay tickets like this show is a multiplication of each of the odds. For example:

  • Atlanta Braves to win @ 1.53
  • New York Yankees to win @ 1.87
  • Boston Red Sox to win @ 2.80
  • Chicago Cubs to win @ 1.87
  • Total odds = 1.53 * 1.87 * 2.80 * 1.87 = 14.98

The total odds for this bet are 8.51. This means that for every $1 you stake, you get parlay payouts of $8.51 (which includes stake).

While it’s important to know how the odds work, it’s not imperative as most sportsbooks will automatically work out the odds as you include selections to your bet slip. They will also allow you to enter a stake to see the larger payout and potential returns before confirming your bet.

Real-World Parlay Bet Examples and Payouts

The range of bets that you can place with a parlay is endless. There are technically unlimited combinations, however, the most common come from 2, 3, and 4-game bets.

In the section below we’ve included real-world examples of how these work by parlay definition.

2-Team Parlay

A two-team parlay is where there are just two selections in the bet. The term “team” is often used, but it can include a range of bets across the sportsbook that aren’t necessarily teams. For example, you might choose the most running yards from two players within an NFL game.

2-way parlay bet

3-Team Parlay

The 3-team parlay is where you have three selections for your bet. As per parlay betting rules, the bet needs all three selections to win for the bet to pay out.

3-way parlay

4-Team Parlay

All 4-team parlay bets are simply another extension of the examples above, but with four picks in it. As we’ve stated, there are no limits on how many selections you can include, which is one of the best features of this bet type.

Bigger Forms of Parlay Bet

The five-team parlay combinations involves five picks. Six selections go into a six-team wager. Seven for seven-team parlay and so on.

Types of Parlay Bets

Parlay betting has a couple of variations that work similarly. However, they are different so you must understand the difference between the two. We’ve outlined these below.

Round Robin

A round-robin is one of the best parlay bets and is made up of multiple selections that form smaller parlays. They are designed so that your total liability is not linked to all results and instead you can still profit from one or more selections that win.

These types of bets are highly flexible and the more teams that you add, the more money you can make. The easiest example to work through is a three-team round-robin bet, which might look something like this.

  • Team 1 and Team 2 to win
  • Team 2 and Team 3 to win
  • Team 1 and Team 3 to win
  • All three teams win

Your stake will be split based on all four outcomes. So, if you wanted to bet $10 per line, then the total here would be $40.

Payouts are based on the odds for each result. The odds are simply multiplied by each other, just as you would a parlay. If we assume that all three teams are priced at even money (2.0 or +100) then you would multiply 2 *2 to make odds of four. For the final line, you multiply all three odds, so it would be 2 * 2 *2 = 8.00 (+700).

You can choose how many picks you want to include and the number of bets you want to make. It’s possible to make hundreds of combinations with just a handful of selections.

Teaser

Teasers are designed to work with spread or totals bets. You’re not able to use these with moneyline bets as they move the line/spread in favor of the team you choose. The tradeoff is that you get lower odds as a result, but you get a much more favorable line and by combining them into a parlay, can still create lucrative odds.

Lines can move between +6 and +10 points, depending on the sport and market you’re betting on. With the NFL, for example, a teaser sports betting line may end up at +6 points, meaning you get 6 more points in your favor.

If the spread for Green Bay Packers to win was +4.5, then this would be adjusted to +10.5, an increase of +6 points.

Parlay Cards

Parlay cards are popular in casinos, especially in the likes of Las Vegas, Nevada. They are essentially a long list of bets that can be placed to create a parlay but instead of the odds being dependent on the price set by the sportsbook, they are instead a fixed price.

parlay cards

For example, there might be 30 teams that you can pick from on the card and the more picks you make, the more the odds will increase. 3 picks might pay +500, 4 picks + 1100, 5 picks +2500, and so on.

Parlay cards can offer value based on the spread that you’re betting on. It might be that the fixed price pays more than if you were betting on each line individually or it could be that the line is more favorable using this method.

To get the most value from this, you need to compare the odds to the card and then to the online odds. There are Parlay cards across all major leagues and US sports like MLB, NBA, NHL and NFL, and college games too.

Pros and Cons of Parlay Bets

Like all bet types, parlay betting has its pros and cons. In this section, we’ve outlined reasons for and against using this betting method.

Pros

  • Huge returns – It’s one of the few bet types that allow you to win huge sums of money for a relatively small outlay.
  • Highly flexible – You can include bets from different sports and markets to create a unique bet.
  • Increased excitement – The bets can last a long period. For example, you could have a parlay that covers all the weekend NFL games, allowing you to watch games that usually you would have no connection to with great interest.
  • Best used with extensive research – These bets are ideal for punters who like to spend a lot of time finding value. When odds are low, but the bet looks strong, you can combine them into bets that will offer a much more enticing payout.

Cons

  • Enhanced juice – All bets come with juice applied by the sportsbook. As you add more selections in, the juice that you’re paying only multiplies, giving the sportsbook a bigger edge.
  • Low success rate – The increased number of picks means that success rates on these bet types are low. The more picks you include, the less likely it is you will win.

Parlay Betting Tips and Strategy

To increase your chances of winning more frequently with parlay bets, we’ve included a list of tips and strategies that you can apply.

1. Use a Parlay Odds Calculator

A simple, but important first step is to use a parlay odds calculator. This will allow you to see how the odds change based on the selections that you include or remove. Most sportsbooks will have this, but if not, try Ace Odds which has one of the best parlay calculators in the business.

2. Increase Exposure to Weak Lines

Weak lines are relatively common in US sports like NBA basketball just from the sheer volume of games and sportsbooks. When a betting site gets a large wager on one result, they balance it up by offering a more lucrative line on the opposing result to generate a more balanced book.

Ideally, you want to be betting the max on the weaker line, but this is not always possible due to bankroll limitations. To maximize returns in the long run you can add this to a betting parlay (preferably with additionally weak line picks) to generate a better price and larger returns.

3. Hedge Bets

If you want to know how to hedge a bet, you can use a parlay that includes a short-priced favorite and an underdog. The favorite will likely offer little value to most punters based on smaller bet sizing, but the inclusion of the underdog will boost the overall profit that can be made.

When it comes down to the last leg of the parlay (assuming that all other picks have won and the bet is still live) you can bet on the opposite side of the profit that can be made. For example, if you’re waiting on the New England Patriots to win as part of your 5-fold parlay on Monday Night Football, you can back against them as a single to either lock a profit on all results or limit exposure to make sure you get your money back.

4. Use a Betting Bonus

Even standard parlays are tough to win, but one of the ways you can limit liability is by using a betting bonus. Most online offshore sportsbooks have some form of welcome offer or reload bonus that allows you to use this with a parlay.

Instead of using your own cash, you can use the betting bonus to run the free money up to a sizeable bankroll. If you choose to do this with a 3-team parlay, then doing so will give you a bigger return from a single bet than you would if you were to place three singles and roll over the cash into each pick.

Correlated Parlay Bets

Correlated parlays are where you have two picks that are tied together. Basically, if one of the picks comes in, it means that the other is much more likely.

These bets are generally linked to same-game bets. For example, if you bet on NFL games with the teams you pick to cover +10 points spread then it’s likely the game is going to be high scoring. This means that as a result, the totals market will have a much stronger chance of winning.

Both established and new betting sites generally don’t allow correlated parlay bets as a rule. It means their exposure would be huge to markets that are correlated and would likely mean they would lose a considerable amount in the long run.

However, there are times when you can place correlated parlays as part of a feature on the sportsbook. These are generally part of a Bet Builder or Parlay Builder feature that allows you to pick bets from multiple markets for the same game.

By doing so, the bookmaker can adjust the odds for the bet, which allows punters to still place the bet, but at reduced odds from the standard lines for those markets.
