Parlay betting can be a thrilling way to chase big payouts — but with high rewards come high risks. One wrong pick and your entire bet goes down the drain.

What is a Parlay Bet?

A parlay bet (also known as an accumulator, multi, or combo bet) combines two or more individual bets into a single wager.

  • To win, all selections (legs) must be correct.
  • Even if one leg loses, the entire bet is lost.

You need at least two independent bets to create a parlay. Anything less is just a regular single bet.

Most bookmakers set a limit on how many legs you can include:

  • For example, BetMGM allows up to 10 legs in same-game parlays and 16 legs in traditional parlays.
  • Limits may vary by sport, event, or market.

Important: You can’t include correlated bets — that is, selections that influence each other. For instance, you can’t parlay “Team A to win” and “Team A to score under 2.5 goals” in the same match unless it’s a same-game parlay specifically designed for that.

How to Place a Parlay Bet

Placing a parlay is straightforward:

  1. Choose your events — Pick two or more games or outcomes.
  2. Add selections — Add them to your bet slip.
  3. Select “Parlay” or “Accumulator” — Bookmakers often group them automatically.
  4. Enter your stake — Decide how much to wager.
  5. Place your bet — Confirm and place the parlay.

If all legs win, you’re paid out at combined odds — significantly higher than a single bet.

Calculating Parlay Payouts

EventBetOddsResult
Barcelona vs Real MadridBarcelona to win1.90Win
Manchester United vs LiverpoolBoth teams to score1.80Win
Bayern Munich vs PSGPSG to win3.50Loss

Let’s say you wagered a $100 bet on this 3-event parlay, the total odds of the bet would be:

1.90 x 1.80 x 3.50 = 11.97

If all three events win, your potential payout would be $1,197 ($100 x 11.97). However, if even one event loses, your entire bet loses.

Cashing Out of a Parlay

If some of your parlay legs have already won, your sportsbook might offer a cash out option. This gives you a chance to lock in a profit or cut losses before all events are settled.

The offer depends on:

  • How many legs are still pending
  • The current odds of those remaining legs
  • Your original stake

Cash out can be a smart move in risky situations — or a regret if the last legs win big.

Pros and Cons of Parlay Bets

Pros

Potential for large payouts
Ideal for big matches or weekends

Cons

One loss kills the whole bet

Bookie’s margin is applied to every leg

FAQ

What’s a parlay bet?

A parlay is a single wager that includes multiple bets. You win only if all your selections are correct.

How is a parlay different from a system bet?

A parlay requires all legs to win. A system bet (e.g. 2/3 or 3/5) still pays out partially even if one or more legs lose.

What’s the catch with parlays?

Two things: the bookmaker applies their margin to every leg, which compounds your disadvantage; it’s psychologically tempting — bettors often overestimate the probability of long parlays, especially with favorites.
