Parlay Bet Explained
A parlay (or accumulator) combines multiple bets into one — all must win for you to cash. Parlays offer exponentially higher payouts than straight bets, but they're much harder to win. In this guide, we'll explain how parlay odds work, how to calculate payouts, and strategies to improve your chances. All information verified by our team of experts.
⚠️ Important: Parlays Have Higher House Edge
While parlays offer exciting big payouts, sportsbooks make more money from them than straight bets. The more legs you add, the higher the house edge. Use parlays occasionally for entertainment, not as your primary betting strategy. Responsible gambling resources →
How Parlay Odds Work
Parlay Odds = Decimal Odds₁ × Decimal Odds₂ × ... × Decimal Oddsₙ
Example: -110 (1.91) × -110 (1.91) = 3.65 odds
$10 bet pays $36.50 ($26.50 profit)
What is a Parlay?
A parlay links two or more individual bets. All selections must win. If any leg loses, the entire parlay loses. Also called accumulator, combo bet, or multi.
Straight Bet vs Parlay
Straight bet: one selection, lower payout, higher win probability. Parlay: multiple selections, much higher payout, much lower win probability. Risk vs reward trade-off.
Push in Parlays
If a selection pushes (ties), that leg is removed. A 3-team parlay with one push becomes a 2-team parlay. Odds recalculate. Push doesn't lose the parlay.
Same Game Parlays
Combine multiple bets from a single game (spread, total, player props). Popular but correlated outcomes may be restricted. Higher risk but convenient.
Parlay Payout Examples ($10 Bet)
| Number of Teams | Odds (All -110) | Payout | Win Probability |
|---|---|---|---|
| 2 | 3.65 | $36.50 | ~25% |
| 3 | 6.96 | $69.60 | ~12.5% |
| 4 | 13.28 | $132.80 | ~6.25% |
| 5 | 25.36 | $253.60 | ~3.13% |
| 6 | 48.43 | $484.30 | ~1.56% |
| 7 | 92.50 | $925.00 | ~0.78% |
| 8 | 176.68 | $1,766.80 | ~0.39% |
| 9 | 337.46 | $3,374.60 | ~0.20% |
| 10 | 644.55 | $6,445.50 | ~0.10% |
Note: Win probability assumes 50% chance per leg (rough estimate). Actual odds vary by bet type.
Types of Parlays
🎲 Standard Parlay
All or nothing
Traditional parlay where all selections must win. Highest potential payout but highest risk. Most common type.
🎯 Same Game Parlay
Single game
Combine multiple bets from one game: spread, total, player props. Popular for football and basketball. Correlated bets may be limited.
🔄 Round Robin
Multiple parlays
Creates smaller parlays from your selections. If you pick 3 teams, you get 3 two-team parlays. Reduces risk. Calculator →
📊 Teaser
Adjusted spreads
Parlay where you can adjust point spreads in your favor. Lower payout but higher win probability. Teaser guide →
🏈 Progressive Parlay
If bets
Winnings from each leg roll to next bet. If first wins, second bet uses those funds. Complex but offers flexibility.
🎰 Action Parlay
Substitution allowed
If a game is postponed, it's substituted with another game. Not common in US sportsbooks.
Parlay Risks & Reality
Exponential Odds Growth
Odds multiply quickly. A 10-team parlay at -110 each pays over 600-1. But probability of winning is about 1 in 1,000. Long shots rarely hit.
Higher House Edge
Sportsbooks build a larger margin into parlays. The more legs, the higher the house edge. Straight bets offer better value long-term.
One Leg Away
Nothing hurts more than having 5 of 6 legs win. You get nothing. This is why many bettors prefer round robins.
Correlation Issues
Some correlated bets (e.g., QB over passing yards + WR over receiving yards) may be restricted or offer worse odds.
Promotion Traps
Parlay insurance (refund if one leg loses) sounds good but usually requires 5+ legs. Still high risk for small reward.
Bankroll Killer
Chasing big parlay payouts can quickly drain your bankroll. Small stakes recommended. Never bet more than you can afford to lose.
Parlay Betting Strategies
1. Limit to 2-3 Legs
Small parlays offer the best balance of risk and reward. 2-team parlays win about 25% of the time with -110 odds.
2. Focus on One Sport
Specialize in one league where you have deep knowledge. NFL, NBA, or MLB — not mixing across sports.
3. Use Promotions Wisely
Take advantage of parlay insurance, odds boosts, and profit boosts. But read terms carefully.
4. Consider Round Robins
Instead of one big parlay, use round robins to create multiple smaller parlays. Reduces risk of total loss.
5. Mix Favorites and Dogs
Combining heavy favorites with underdogs can create value. A -300 favorite (+ $10 bet wins $3.30) paired with a +250 underdog.
6. Avoid Correlated Bets
Bookmakers limit correlated outcomes. If you find a loophole, it may be closed quickly.
How to Calculate Parlay Payouts
Multiply All Odds
1.91 × 2.50 × 1.91 = 9.12 total odds.
Multiply by Stake
$10 × 9.12 = $91.20 total payout ($81.20 profit).
❓ Frequently Asked Questions
What is a parlay bet?
A parlay (also called accumulator or combo bet) is a single bet that links two or more individual wagers. To win a parlay, all selections must win. The payout is much higher than individual bets because the odds multiply together.
How do parlay odds work?
Parlay odds are calculated by multiplying the decimal odds of each selection. Example: -110 odds convert to 1.91 decimal. A 2-team parlay: 1.91 × 1.91 = 3.65 odds. A $10 bet pays $36.50 ($26.50 profit).
What happens if one leg of a parlay pushes?
If a selection pushes (ties), that leg is removed from the parlay. The parlay then becomes a smaller parlay. Example: 3-team parlay with one push becomes a 2-team parlay. Odds recalculate accordingly.
What is a same game parlay?
Same game parlay combines multiple bets from a single game (e.g., player props + spread + total). Offered by most sportsbooks now. Correlated outcomes may be restricted.
What is a round robin?
Round robin creates multiple smaller parlays from a set of selections. If you choose 3 teams, you get 3 two-team parlays. Reduces risk compared to one big parlay. Round robin calculator →
Are parlays worth it?
Parlays have higher house edge than straight bets. Sportsbooks profit more from parlays. However, they offer excitement and chance at big payouts with small stakes. Best used occasionally for entertainment.
