What this means
A parlay multiplies the decimal odds of every leg together. All legs have to win for the parlay to cash; if any one loses, the entire parlay loses.
Combined odds get long fast — three -110 legs is roughly +600 but only about 12.5% implied to win. Books love parlays because the vig compounds across every leg, so the true edge required to make money on them is higher than on straight bets.
For same-game parlays (correlated legs), this calculator over-states the payout because real SGP books apply correlation discounts. Use the SGP tool for those.
