A teaser is a special kind of parlay where the bettor gets assistance on the point spread for a decreased payout. The most common football teaser is a 6-point, two-team teaser. The bettor selects two teams, and gets six points added or subtracted from each of their point spreads. If you are looking at a 3-point underdog, a 6-point teaser would now give them nine points in the game. If you are looking at an 8-point favorite, a 6-point teaser would now require them to win the game by more than two points instead of eight. Each leg of the teaser has to hit in order for the ticket to cash.
