Show full assessmentShow less

The resolution criteria clearly define the point thresholds for Over and Under outcomes based on the total combined score. While no specific official statistics provider or league website is explicitly named as the resolving authority, the final score of a professional basketball game is an objective and verifiable outcome. The rules also explicitly account for potential schedule changes by remaining open if the game is postponed and resolving evenly at 50-50 if it is canceled without a make-up game.
