What is a parlay bet?

A parlay (also called an accumulator or combo bet) combines two or more individual bets into one wager. All selections must win for the parlay to pay out. The advantage is a much larger payout than individual bets, but the risk is higher because a single loss means the entire parlay loses.

How are parlay odds calculated?

Parlay odds are calculated by multiplying the decimal odds of each leg together. For example, three legs at -110 (1.909 decimal) each: 1.909 x 1.909 x 1.909 = 6.96, which is about +596 in American odds. A $100 bet would pay $696.

Are parlays a good bet?

Mathematically, parlays have a higher house edge than straight bets because each leg's vig compounds. However, they can be strategically useful when you have correlated outcomes or strong convictions on multiple games. The key is to use them sparingly and with proper bankroll management - never bet more than 1-2% of your bankroll on a parlay.

What happens if one leg of a parlay pushes?

If one leg pushes (ties), most sportsbooks remove that leg and recalculate the parlay with the remaining legs. A 4-leg parlay where one pushes becomes a 3-leg parlay. A 2-leg parlay where one pushes becomes a straight bet.

What is the maximum number of legs in a parlay?

Most sportsbooks allow between 10-15 legs in a parlay, though some allow up to 25. As the number of legs increases, the odds of winning drop dramatically while the payout increases. A 10-leg parlay at -110 odds has only about a 0.1% chance of winning.

Everything you need to know about parlay bets: how they work, the math behind them, strategy tips, and a complete odds chart.

How Parlays Work

A parlay combines multiple individual bets (called "legs") into a single wager. The catch: every leg must win for the parlay to pay out. If even one leg loses, the entire parlay loses.

The appeal of parlays is the multiplicative payout. While a single bet at -110 returns just $90.91 profit on $100, a 3-leg parlay at -110 odds per leg returns $596 profit. The tradeoff is a much lower probability of winning.

The Math Behind Parlays

Parlay odds are calculated by multiplying the decimal odds of each leg together:

Example: 3-Leg Parlay

Leg 1: -110 = 1.909 decimal

Leg 2: -110 = 1.909 decimal

Leg 3: +150 = 2.500 decimal

Combined: 1.909 x 1.909 x 2.500 = 9.112

$100 bet pays $911.20 (profit of $811.20)

Parlay Strategy Tips

Keep it short (2-4 legs)

Every leg you add dramatically reduces your win probability. The house edge compounds with each leg, making long parlays significantly -EV. Stick to 2-4 legs for the best risk/reward.

Look for correlated parlays

Correlated parlays combine outcomes that are more likely to occur together (e.g., a team winning AND the game going under). Some books limit these, but when available, they offer better value than uncorrelated parlays.

Use proper bankroll management

Never bet more than 1-2% of your bankroll on a parlay. The high variance means you will lose most parlays, so protecting your bankroll is critical for long-term survival.
