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.
Important concepts to understand
Common questions about parlays
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.
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.
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.
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.
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.
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.
