Parlay betting has long been one of the most thrilling formats for sports bettors. A small stake can turn into a massive payout, but only if every single selection in the bet wins. That balance of risk and reward has turned parlays into a popular tool not just for casual bettors chasing big wins, but also for sharp bettors looking for creative ways to stretch value across multiple bets.
According to a 2023 report by the American Gaming Association, parlays accounted for over 30% of total sports betting revenue in states with legalized betting. In some sportsbooks, they’re responsible for an even greater share of profit due to their higher hold percentage. With the continued rise of mobile sportsbooks and crypto platforms, parlay betting has only grown in visibility and accessibility. But it’s not just about potential profit – it’s about understanding the game, analyzing correlations, and playing the odds intelligently.
Let’s take a deep dive into how parlay betting works, what types exist, how to build better parlays, and where to get the best experience in 2025.
A parlay bet—sometimes called an accumulator or combo bet—is a single wager that links together two or more individual bets, and all of those bets must win for the parlay to cash. If even one leg (i.e., one of the individual bets in the parlay) loses, the entire wager is lost. The risk is higher than a standard single bet, but the potential payout is significantly greater due to the compounded odds.
Parlays are incredibly popular among recreational and experienced bettors alike, especially during high-action weekends filled with NFL, college football, or March Madness games. The appeal is obvious: by staking a small amount, bettors can win big if multiple outcomes go their way.
The allure of parlays lies in the high-risk, high-reward nature of the wager. For example, a three-leg parlay made up of standard -110 odds bets can return roughly 6 to 1, turning a $10 bet into around $60. Add a fourth or fifth leg, and the payouts start multiplying dramatically.
In recent years, the rise of same-game parlays (SGPs)—offered by many major sportsbooks—has taken this format to new heights. These allow bettors to combine multiple bets within a single match, such as a player to score, total points, and spread outcome in an NBA game.
Let’s say you're betting on three NFL games:
You combine all three selections into a parlay. All three must be correct for the bet to win. If the Patriots cover the spread and the Chiefs win, but the Eagles vs. Cowboys game ends 20–17, your parlay loses—even though you got two out of three right.
Parlay odds are calculated by multiplying the decimal odds of each selection together. For American odds bettors, sportsbooks typically auto-calculate this, but understanding the math helps demystify the payout structure.
For example:
Parlay odds = 1.91 x 1.91 x 1.91 = approx. 6.97
So a $100 parlay would return nearly $697 (including stake) if all three legs win.
While the upside is attractive, it’s important to highlight that the true odds of winning a multi-leg parlay are significantly lower than many casual bettors realize. Each added leg increases not only the potential payout but also the chance that a single misstep ruins the whole ticket.
This is why seasoned bettors often use parlays sparingly or strategically—some focusing on correlated plays, others taking small shots with low stakes.
Parlay odds are calculated by multiplying the decimal odds of each leg. For example, if you place a 3-leg parlay with odds of 1.91, 2.00, and 1.85, the combined payout would be:
1.91 × 2.00 × 1.85 = 7.07 (or +607 in American odds)
So, a $10 bet would return $70.70 including the stake.
Payouts scale quickly with additional legs, but the risk increases dramatically. Just one upset or a last-minute touchdown can destroy an otherwise perfect parlay.
Pushes (tied bets) are typically removed from the calculation, turning a 3-leg into a 2-leg bet and adjusting the payout accordingly. It's essential to understand the house rules, as sportsbooks vary in how they handle ties, voids, and canceled events.
There’s more than one way to build a parlay. Here are the most common formats:
Each format has its use case – same-game parlays for high-profile matches, teasers for more conservative strategies, and standard parlays for those aiming at long shots.
While parlays can feel like lottery tickets, there’s more than luck involved. Smart bettors apply strategy and discipline. Here are several principles to consider:
First, always manage your bankroll. Because parlays carry higher variance, they shouldn’t dominate your betting activity. A typical recommendation is no more than 5–10% of your total bets as parlays.
Next, limit the number of legs. While the idea of a 10-leg parlay is tempting, your actual win probability drops sharply with each added leg. Statistically, 2-leg and 3-leg parlays offer better long-term value.
Avoid correlated outcomes unless you’re building a same-game parlay where it’s allowed. For example, betting on a team to win and the total to go over may be related – and some sportsbooks restrict such combos unless explicitly in a same-game parlay format.
Pay attention to value. Even if each leg is a favorite, if the odds are overvalued, your parlay becomes a low-return risk. The best parlay bettors hunt for mispriced lines and favorable matchups.
Lastly, don’t chase losses with big parlays. It’s a common trap. Stick to your plan and bet amounts, no matter the results of your previous tickets.
While you can build a parlay across almost any sports market, some sports are naturally suited for the format.
NFL and college football are among the most popular due to the weekly schedule and point spread market. Teasers are also widely used in football, as shifting lines by 6–7 points can make a dramatic difference.
NBA is excellent for same-game parlays, thanks to high-scoring environments and deep player prop markets. Soccer accumulators are popular in Europe, stacking up several teams to win across different leagues.
UFC parlays often include multiple fights on the same card. And MLB, with its daily rhythm and underdog volatility, offers a fertile ground for building value-oriented parlays.
Each sport brings different dynamics. The key is understanding how the variance of the sport aligns with your parlay construction.
