Parlay (Accumulator)
One ticket that ties together two or more picks, and every single one has to win for you to get paid.
A parlay, sometimes called an accumulator or “acca,” is a single bet that rolls two or more picks into one. The catch is simple: every pick on the ticket has to win, or the whole thing is a loss. Even one losing leg sinks it. What makes parlays so tempting is the way the odds stack up. Each pick’s odds multiply together, so the payout climbs fast as you add legs, well beyond what those bets would return on their own.
You can build a parlay on just about any sport or bet type. Mix and match moneylines, point spreads, totals (over/under), and even props all on one ticket. Most sportsbooks let you start with as few as two legs and go up to ten or more, though the limit depends on the book.
Example
Say you put down a $10 three-leg parlay:
- Leg 1: Kansas City Chiefs moneyline at -150 (decimal odds 1.67)
- Leg 2: Over 45.5 points in the Packers vs. Bears game at -110 (decimal odds 1.91)
- Leg 3: Buffalo Bills -3.5 at -110 (decimal odds 1.91)
Multiply the decimal odds together: 1.67 x 1.91 x 1.91 = 6.09. Your $10 bet would pay out $60.93, a profit of $50.93. Hit all three legs and that’s yours. But if the Chiefs win and the over cashes while the Bills miss the cover, the whole $10 is gone.
Key Points
- All-or-nothing: Every leg has to win. One loser and the entire ticket loses, no matter how the rest played out.
- Odds compound into big payouts: Multiplying each leg’s odds means payouts grow fast as you add picks, which is why parlays draw bettors chasing big returns on small stakes.
- Bigger house edge: The payouts look great, but parlays carry a higher built-in house edge than betting each pick separately. Your odds of winning drop with every leg you add.
- Void or pushed legs: If a leg pushes (ties) or gets voided (say, a game is canceled), most books just drop that leg and recalculate the parlay at lower odds instead of grading the whole ticket a loss.
- Correlated parlays are often blocked: Books may limit or ban parlays where the picks are statistically linked, since those combos can tilt the value toward the bettor.
