Combination bets - also known as parlays - are not allowed in related events. That is, where the outcome of one selection in the combination contributes wholly or partly to the outcome of another.
For example, MLB runlines and NHL pucklines of 1.5 and the Over/Under from the same game would be considered related and not permitted.
Occasionally we have specials up for which we do not allow combination bets - ex. Golden Globes, Oscars.
