This error message appears when one (1) or more selections of a parlay bet contribute wholly or partially to the result of another selection, this is known as a related outcome.
The related outcome could be within the same event or across multiple separate events. This restriction is in place as a control to prevent parlays at full multiplied odds between related outcomes.
Parlays on related outcomes are not accepted, however, pre-built Same Game Parlay bets may be available depending on the event.
The chart below shows where selections between markets from the same game might be possible.
