A teaser is like a parlay, but you can add or subtract points from the spread to make your bets stronger. This is called moving the line. Additional points are either added to the underdog or subtracted from the favorite when betting teasers.
The odds change according to the number of points the spread is moved and the number of teams combined to form the teaser.
For example, New York might be favored by 9 points in one game and Chicago might be favored by 12 points in a second game. A 6 point teaser would adjust the Chicago point spread 6 points in the customer’s favor; i.e. Chicago would now be favored by 6 points (12-6=6).
The customer might make a bet on a 6 point teaser with Chicago and New York. In this example, the customer is betting that Chicago will win by 6 points and New York will win by 3 points (9-6=3). As in the parlay, all teams must win.
When betting teasers, ties may be considered losing bets at many sportsbooks, not pushes, so check the rules before you bet. (Monster teasers and/or sweetheart teasers are almost always considered losses if one of your games results in a tie.)
