Parlays combine multiple bets into one wager with a bigger payout — but the catch is that every single leg has to win, or the entire ticket loses.
How the Payout Grows
Combining bets multiplies the odds together rather than adding them, which is why a 3-leg parlay of modest favorites can pay out at 6-to-1 or higher despite each individual leg being a near-coin-flip.
Why the Math Favors the House
The true odds of hitting every leg of a multi-leg parlay drop fast — three legs at roughly 50% each gives you only about a 12.5% chance of cashing the full ticket, even though the payout rarely reflects true odds that precisely once the sportsbook’s margin is built in.
Using Parlays Sensibly
Treat parlays as a small, fun part of a betting budget rather than a primary strategy. Two or three legs at reasonable odds is far more sustainable than chasing a 10-leg long shot.
