There’s always one. Saturday afternoon, and someone’s sitting on a five-leg parlay that’s somehow still alive. A couple of soccer matches, maybe a tennis pick, maybe something random from the NBA. One leg to go, and the payout is stupid.
The group chat is buzzing. Screenshots. Nerves. False confidence.
Then someone asks the question that most people are too embarrassed to admit out loud:
What is a parlay bet?
Don’t worry, every newbie has asked the question at some point. In this article, we break down all you need to know about parlay bets.

What is a parlay bet?
A parlay bet, also known as an accumulator in some regions, is a single wager that links multiple bets, called legs, into one. They are most commonly seen in sports betting. To win the bet, every leg must win. If just one loses, the whole thing falls apart.
For example, you might build a parlay with:
- Arsenal to win
- Over 2.5 goals in PSG vs Real Madrid
- Novak Djokovic to win his match
If all three outcomes happen, your parlay wins. The payout is much bigger than it would be if you’d placed each bet on its own. But if even one result doesn’t go your way, say Arsenal draws, the entire bet loses.
Why do people bet parlays?
The main draw is the payout potential. When you combine multiple bets into a single parlay, the odds are multiplied. That means even modest picks can snowball into a large return.
Let’s say you have three individual bets, each at decimal odds of 1.90.
- A $10 single bet would return $19 if one of them wins
- But a $10 parlay across all three pays around $69 if they all hit
It’s not just the numbers that attract bettors, either. Parlays are incredibly exciting. They give you skin in multiple games at once. You can be tracking goals in Spain, corners in England, and aces in Australia for one bet to come in. That sense of momentum, the possibility of a big win from a small stake, is a big part of the appeal.
What makes parlays risky?
To win a parlay, every leg has to land. That requirement sounds simple, but it’s what makes parlays statistically brutal.
Each outcome you add reduces the probability of winning the overall bet. Even if all your selections seem safe, probability doesn’t play favorites.
Suppose each leg has a 60% chance of winning.
A three-leg parlay then has a 21.6% chance of hitting (0.6 × 0.6 × 0.6 = 0.216). That’s not great.
Go to four legs, and you’re down to 13%.
Now imagine you throw in an underdog just to bump the payout. One upset, and the whole ticket is toast.
That’s why sportsbooks love them, and why bettors need to be cautious. Parlays can be thrilling, but they’re built for volatility. When they win, it’s often memorable. But over time, the house edge kicks in hard.
So don’t be fooled by the big numbers on the bet slip. They might look tempting, but they come at a price.
How parlay odds work
In a parlay, the odds from each leg are multiplied together. That’s what makes the payout grow fast, even if your picks aren’t especially bold.
Take three NFL moneyline bets:
- Bills to win at 1.80
- Chiefs to win at 2.00
- Cowboys to win at 1.90
Multiply them to calculate the parlay odds:
- 1.80 × 2.00 × 1.90 = 6.84
That gives you combined decimal odds of 6.84. If you bet $10 on this parlay, your total return would be $68.40 ($10 × 6.84 = $68.40).
This includes your original $10 stake. So your profit would be $58.40 if all three picks win.
Each extra leg increases the potential payout because you’re stacking more outcomes. There’s no bonus or boost, it’s just basic multiplication. The sportsbook isn’t handing you extra value. You’re simply increasing the number of things that need to go right.
Top tips for winning parlay bets
Parlays are fun to build, but they’re easy to lose if you’re just throwing picks together for the sake of a bigger payout. If you want to take them seriously, you need to approach them like you would any other bet—with a plan.
Keep your parlays short
Stacking up a 10-fold accumulator of both teams to score in every Premier League game might sound fun. Until the early kickoff ends 0–0 and kills the whole thing before lunch.
A common mistake is thinking more legs means more chance to win big. It doesn’t. It just means more ways for the whole thing to fall apart. Stick to two or three confident picks. Four at most.
That keeps your chances realistic and gives you a chance to figure out where your bets are working. Ten-leg combos might have huge odds, but you’re setting yourself up for a loss.
Don’t load up on favorites
Parlays built from a bunch of big-name favorites feel like a smart way to win something—especially when the individual odds look safe. But they rarely work out that way.
The first issue is risk. Even short-priced teams lose. All it takes is one upset, one red card, or one off day, and the whole bet is gone.
The second issue is value. Short odds don’t give much back. A parlay of five teams at 1.30 might only return 3.7 for every 1 unit staked. That’s asking for five things to go right just to triple your money. One slip and you lose it all. The risk-to-reward ratio is completely skewed.
Favorites aren’t the problem. But when they’re the entire parlay, and the odds are tight, you end up with a fragile bet that doesn’t pay enough to justify the risk. It’s better to pick fewer legs and focus on selections where you actually think the odds are worth it.
Every leg needs to stand on its own
If you wouldn’t bet something as a single, it doesn’t belong in your parlay. That’s the rule.
It’s easy to get greedy when you see the payout creeping up. But adding a weak pick just to nudge the return a bit higher usually ends the same way—one leg lets you down, and it’s the one you were never sure about to begin with.
Each leg should be strong enough to carry its weight. For most bettors, this is a smart rule of thumb. But in specific spots—like correlated parlays or hedged exposures—pros might include marginal picks as part of a larger strategy.
Be careful with same game parlays
Same game parlays are tempting because they follow a story. The quarterback throws for 2+ touchdowns, the star receiver scores, and the game total goes over. It all lines up—on paper.
But the tighter the story, the easier it is for one moment to unravel everything. If the game script changes: say the defense dominates, or the weather turns ugly, or one team builds a lead and just runs the ball, your whole setup collapses. Every leg is connected, so when one fails, they usually all do.
The odds might look boosted, but the risk is concentrated because you’re not spreading your bet across different games. Instead, you’re putting all your faith in one outcome unfolding exactly how you imagined.
These parlays can work, but only if you understand how that specific matchup plays out. It’s fine to take a shot, but don’t confuse a good storyline with a smart bet.
Parlays aren’t a fix for losing streaks
When you’re on a bad run, it’s tempting to chase a big win. That’s when a lot of bettors reach for a five or six-leg parlay.
That approach usually makes things worse.
Parlays come with higher risk than single bets. If your selections have been off, stacking more of them into one ticket won’t improve your chances. It just gives you more ways to lose again.
You won’t fix your losing by hitting one big bet. You need to figure out what’s been going wrong. That means slowing down, reviewing your decisions, and focusing on better-quality picks. Turning up the risk factor will only hurt your bankroll (and ego) more.
Use free bets to take bigger swings
When you’re not risking your own cash, you can afford to go bigger.
A free bet is the best time to try a higher-risk parlay. You’ve got nothing to lose, so it’s the right moment to chase upside. That doesn’t mean you throw in nonsense picks just to inflate the payout. Still build it with care, but just aim higher than you normally would.
Turning bonus credit into a real return is one of the few times you can gamble aggressively without gambling recklessly.
What not to do with parlay bets
Even sharp bettors lose parlays. But most parlay losses come down to the same avoidable errors. If you want to avoid throwing away bets, start by spotting the patterns that trip most people up.
Add legs just to boost the payout
It’s easy to fall into this trap. You’ve got three picks you actually like, and then you tack on a fourth to bump the odds. The payout looks better, but the bet doesn’t. That extra leg is often the one that kills the whole ticket.
As we said, if a pick wouldn’t make sense on its own, it shouldn’t be in your parlay.
Include sports you don’t follow
Throwing in a tennis match or a basketball game just because it’s on the homepage is a fast way to tank a parlay. If you haven’t been tracking the sport, you won’t know about injuries, form, style of play. Basically, you’re betting blind on odds that could be terrible.
Stick to sports and leagues you understand. Familiarity gives you a better shot at spotting value and avoiding lazy picks.
Ignore team news and market movement
Imagine the pain when you lock in your parlay on Tuesday because the odds look good. Only to find out by Saturday, the quarterback’s out with a hamstring, two wide receivers are in concussion protocol, and the line has shifted five points. Now, you’re holding a bad number, and you can’t cash out or edit the bet.
In single bets, you can wait for the lineup, follow the market, and adjust. Parlays don’t give you that flexibility. Once it’s placed, you’re stuck with whatever news breaks after.
Always check for updates before finalizing your picks. Wait for injury reports, official lineups, or market movement if you can. Otherwise, you risk anchoring your whole parlay to outdated info—like betting on a team that doesn’t know who their starting quarterback is.
Overuse same game parlays
We briefly mentioned same game parlays before, but we have to reiterate what we said, because it’s one of the top mistakes people make. Especially when betting on their own team or a big game.
Same game parlays are harder to win than they look. The outcomes are usually correlated, which means one surprise result can wipe out the whole thing.Most people build them based on how they hope the game will go, not on how it actually might.
If you’re going to play one, build it like a bet, not a highlight reel.
Treat parlays like a regular stake
Parlays are high-risk bets. They shouldn’t take up the same amount of your bankroll as a single. If you’re staking the same amount on a six-leg combo as you are on a straight win, you’re exposing yourself to big swings.
Keep parlay stakes smaller. They’re meant to be higher variance, so treat them that way.
FAQs about parlay bets
If a game is canceled or a player pulls out, that leg is usually treated as void. The parlay stays active, and the odds are recalculated based on the remaining selections.
In some cases, yes. It depends on the sportsbook and how many legs have settled. If most of your picks have already won, you might be offered a partial cash out before the final leg.
No. Parlays are much harder to win. Industry data suggests parlay hit rates vary significantly by number of legs, but most multi-leg parlays have a win rate well below 25%—sometimes under 10% for longer combos. With singles, you only need one outcome to go your way. Parlays need every leg to hit, so the more you add, the lower your chance of winning.
For most bettors, two to four legs is the sensible range. It gives you a decent payout without asking for too much to go right.
Yes, there are a few different types, and each one works slightly differently. Understanding the format helps you manage the risk and avoid betting on something you don’t fully understand.
Standard parlay
This is the basic version. You combine two or more bets, usually from different games or sports, into one. Every single leg needs to win for your parlay to pay out. If just one loses, the entire bet fails. The more legs you add, the higher the payout, but also the higher the risk.
Same game parlay (SGP)
This type lets you build a parlay from multiple bets within one game. For example, in an NFL matchup you might combine:
– A team to win
– A specific player to score a touchdown
– The total points to go over 47.5
These are popular because they follow a logical narrative, but they’re harder to win than they look. If the game doesn’t go the way you expect, every part of the parlay can collapse at once.
Round robin
A round robin breaks your picks into multiple smaller parlays. Instead of putting all your money on one big combo, it covers every combination of your selections. If you choose three teams, it creates three two-leg parlays and one three-leg parlay.
This means if one leg fails, you might still win money on the others. It costs more to place, but gives you a safety net.
Teaser
Teasers are mostly used in NFL and NBA betting. They let you shift the point spread or total in your favor, which makes the bets easier to win, but also reduces your payout.
For example, if the Bills are -7 and the Chiefs are -6, a 6-point teaser moves those lines to Bills -1 and Chiefs pick’em. That means the Bills only need to win by two, and the Chiefs just need to win the game. It gives you more breathing room, but you’re paid less because of it. Like a standard parlay, all your picks still need to win for the teaser to pay out.
They’re related, but not exactly the same. A parlay is a type of multiple bet, it combines two or more picks into a single wager where every leg has to win.
The term multiple bet is broader. It includes parlays, but also things like round robins and system bets, where not every pick has to hit for you to get a payout. So all parlays are multiples, but not all multiples are parlays.
