Understanding Parlay Betting with BetMGM
A parlay is a wager that combines multiple individual bets into one, where all selections must hit for the bettor to win. This results in bigger payouts than separate individual bets as the combined odds increase both the risk and reward.
At BetMGM Sportsbook, you can create parlays by selecting multiple bets across different sports and events, including moneylines, point spreads, totals, player props, and game props. They also have same-game parlays that combine multiple selections from one event into one wager.
To create a parlay with the sportsbook, you can add multiple selections to your bet slip, and the site will calculate the combined odds and potential payout for you. BetMGM also has parlay boosts and additional promotions available.
This guide will take you through the types of parlay bets available at BetMGM, the rules associated with them, how their odds are calculated, and how to place these bets.
Types of Parlays on BetMGM
Any wager that combines multiple bets can be considered a parlay, but it's worth familiarizing yourself with the subgenres of this bet type.
Traditional Parlays
A traditional parlay is a type of sports bet where you combine multiple individual bets into one bet.
Each of those individual bets are called “legs”. If one of those legs loses, the entire parlay loses.
For example, if you bet on the Denver Broncos to win, the Seattle Seahawks to cover a -6.5 spread, and the total in Kansas City Chiefs vs. Cincinnati Bengals to go over 45.5 total points —all three have to hit for the parlay to pay out.
A traditional parlay doesn't have to feature events from the same day. It could include three futures bets that take months to resolve. In 2022, one BetMGM bettor used a $500 free bonus bet to wager on the Colorado Avalanche to win the Stanley Cup, the Los Angeles Rams to win the Super Bowl, and the Golden State Warriors to win the NBA Finals.
It resulted in a $269,000 win.
Same-Game Parlays
A same-game parlay (SGP), or one-game parlay, is a wager on multiple outcomes within a single event.
Unlike traditional parlays, where you bet on multiple games or events, SGPs allow you to bet on one game and make predictions about different parts of the outcome. All legs of the parlay must win for the bet to hit, and the payout is calculated by multiplying the odds of each selection, so the more correct, the more you win.
For example, in an NFL game between the Buffalo Bills and New York Jets, you could create a same-game parlay by betting on Buffalo to win (moneyline), the total score to go over 45.5, and Josh Allen to score a touchdown.
If all three happen, you win the parlay. But if one of them doesn’t, you lose the entire bet.
An important element to navigate with these parlays is the correlation between events. For instance, if the Bills are favored by 6 points in their game against the Jets, you can't back them on the spread and moneyline on two different bets with a same-game parlay. That's because if they cover the spread, they have, by definition, won on the moneyline, so a sportsbook will not give you extra credit for correctly predicting that outcome.
That said, there are bets that you can still combine that may be related. In some cases, a team is highly reliant on one player to produce in order to win. If you feel good about their chances, you might want to bet on that team's moneyline and an over on one of that players props.
In the 2024 NFL regular season, the Houston Texans were 5-0 when C.J. Stroud managed at least 250 passing yards and 5-7 when he didn't. Stroud eclipsing that number didn't magically make them win, but victories were hard to come by when he didn't move the ball through the air. If you thought Stroud was in for a big day, you might want to fold an over on his passing yardage into a same-game parlay that also included the Texans moneyline.
Pre-Packaged Parlays
Pre-packaged parlays can come in a variety of different forms. They can be either traditional parlays that span multiple events or same-game parlays.
What differentiates them is that they have been built by a sportsbook platform like BetMGM, which promotes them on their platform.
The upside of this kind of bet is that it tends to capture a specific theme or broad outcome (i.e., a huge day for the Kansas City Chiefs passing attack) that might appeal to a bettor while saving them some time on research.
The downside is that they, like all parlays, are relatively unlikely to hit. It is also fair to be skeptical about the value of a parlay that a sportsbook is putting together. While betting platforms are more interested in long-term profitability than individual bets, they are not charitable organizations designed to put money in bettors' pockets.
