What is a Parlay?
A parlay is a single wager that features multiple selections. These selections are known as legs. It is referred to as an accumulator, or an acca, in some countries.
The idea is to roll multiple predictions into a single bet in an effort to generate a large profit. Each selection must prove correct in order for your parlay to pay out. If just one leg lets you down, your parlay will crash and burn. However, if they all pay off, you will earn a far larger profit than you would have made by betting on each selection individually.
For example, you could bet $10 on the San Francisco 49ers to cover the spread against the LA Rams at odds of -110, $10 on the New York Giants to cover against the Dallas Cowboys at -110, and $10 on the Seattle Seahawks to cover against the Arizona Cardinals at odds of -110, for a total stake of $30.
If all of your predictions were successful, you would earn a profit of $29.70. However, if you rolled all three into a $30 three-team parlay, you would earn a profit of $178.74 if all three selections were winners.
That assumes that you are getting a fair parlay payout at your sportsbook. You can use our

How Are Parlay Odds Calculated?
True parlay odds are calculated by figuring out the return you stand to earn on each selection and multiplying those figures together. The easiest way to manually calculate the combined odds on a parlay bet is to convert each selection from American odds to decimal odds.
For example, let’s say you are interested in combining these selections:
#1. Atlanta Braves to beat Toronto Blue Jays at -150 (1.67 in decimal odds)
#2. Philadelphia Phillies to beat Washington Nationals at -108 (1.93)
#3. New York Yankees to beat Tampa Bay Rays at -131 (1.76)
#4. Arizona Diamondbacks to beat Miami Marlins at +105 (2.05)
You would then multiply these money line odds together: 1.67 x 1.93 x 1.76 x 2.05 = 11.62. That tells you the odds on this four-team parlay should be 11.62, which is +1062 in the American odds format.
