Quick Answer

Key concepts at a glance

Parlay odds multiply together. A 3-leg parlay at -110, -110, +150 equals combined odds of +595 (6.95 decimal). A $100 bet returns $695 if all legs win. Multiply decimal odds: 1.91 × 1.91 × 2.50 = 9.10, then subtract 1 and multiply by stake for profit.

Key Facts About Parlays

Important concepts to understand

  • Parlay odds are calculated by multiplying the decimal odds of each leg together
  • All legs must win for a parlay to pay out - one loss loses the entire bet
  • If a leg pushes (ties), it's typically removed and the parlay recalculates with remaining legs
  • The house edge compounds with each leg, making large parlays heavily favor the sportsbook
  • Same-game parlays (SGPs) often have correlated outcomes and may be priced differently
  • A 2-leg parlay at -110/-110 has about 27.5% win probability vs 50% for straight bets
  • Expected value of parlays is typically worse than straight betting due to compounded vig

Frequently Asked Questions

Common questions about parlays

How are parlay odds calculated?

Convert each leg to decimal odds and multiply them together. For American odds: +150 = 2.50, -110 = 1.91. If you have 3 legs at 2.50 × 1.91 × 2.00 = 9.55 decimal odds, or +855 American. Your potential payout is stake × combined decimal odds.

What happens if one leg of my parlay pushes?

Most sportsbooks remove the pushed leg and recalculate the parlay with remaining legs. A 4-leg parlay with one push becomes a 3-leg parlay. Some books may void the entire parlay if any leg pushes, so check the rules.

Are parlays profitable long-term?

Generally no. While parlays offer bigger payouts, the house edge compounds with each leg. A 2-leg parlay at standard -110 juice has about 4.5% edge against you. A 5-leg parlay can have 20%+ house edge. Parlays are entertainment, not strategy.

What is a round robin bet?

A round robin is a series of smaller parlays created from a larger selection. For example, picking 4 teams and creating all possible 2-team parlays (6 bets) or 3-team parlays (4 bets). It provides parlay upside with some loss protection.

How many legs can a parlay have?

Most sportsbooks allow 2-15 legs per parlay. Some allow up to 25. Maximum payout caps usually apply regardless of legs - often $1M or less. The more legs, the lower your win probability and the higher the house edge.

What are same-game parlays (SGPs)?

SGPs combine multiple bets from the same game (e.g., player props + game total + spread). Sportsbooks price these specially because outcomes can be correlated. SGP odds may be worse than true mathematical odds due to correlation adjustments.
