Term Definition
Half-point In sports betting, a “Half-point” refers to a situation where a point spread includes a half-point to prevent a push or tie. This means that the final score must be either above or below that half-point in order to determine a winner. For example, if a team is favored to win by 3.5 points, they must win by 4 or more points to cover the spread.

For example, if a team is favored to win by 3.5 points, they must win by 4 or more points to cover the spread and win the bet. If they only win by 3 points, then the bet would result in a push or tie, meaning that the bettor’s money would be returned to them.

This concept is used as a way to make betting more challenging and interesting and to encourage more betting activity. It is important for individuals who engage in sports betting to understand the concept of half-points and how they may affect their bets. [1]
