No parlay wagers can be accepted where individual wagers are considered being ‘connected’, ‘dependent’ or ‘correlated’.
Using a baseball game as an example, suppose a bettor was interested in taking the Boston Red Sox to win on the moneyline AND the Boston Red Sox on the run-line. If the Boston Red Sox win the game, it is also likely that they will win by at least two runs. Since the two wagers’ outcome are so closely tied together, the selections are deemed as being ‘correlated’ and cannot be parlayed together. For this same reason, we do not allow the favorite/underdog on the run line and the over/under of the same game to be paired together in the same parlay.
Similarly, parlaying the line for the first half of a football game with the line for the whole game is disallowed. Bettors may not combine the total for the first half of a football game with the total for the whole game, as these also are correlated outcomes.
Should an event’s point spread represent greater than or equal to 30% of the total, combining the favorite/underdog against the spread with the over/under of these games are also prohibited for correlation purposes.
