What are American Football Asian Handicap bets?

mechanics

• Half-point lines (±0.5, ±1.5, ±2.5…): always a clean win or full loss. Spreads with a half-point (e.g. −6.5) are common in American football to eliminate push possibilities.
• Whole-number line (e.g. −7): if the favorite wins by exactly 7, both parts of a quarter-line split push. A straight whole-number line pushes on an exact margin.
• Example — Home −6.5: the home team must win by 7+ points. A 6-point win (e.g. 17–11) loses the bet.
• Settlement uses the full-game score including all overtime periods. If the match does not start on the scheduled date, or is not completed within three days, bets are void. If it starts but is abandoned, bets stand only if at least 55 minutes have been played and an official result is called — otherwise they are void unless already unconditionally determined.
