Teaser Bets Definition
Teaser bets are in some ways similar to parlays considering that all selections need to win in order to qualify for returns, while it is the bookies that determine which matches will be combined to create a teaser bet. The bookmaker also specified how many points you will get to create a teaser.
The main thing that differentiates teasers from parlay bets is that punters are allowed to move the line or the point spread in their favour, so as to increase their winning chances.
By moving the point spread in his favour, the player will be forced to place his bet at lower odds than originally specified, but that is a risk most bettors are willing to take.Example
The bookmaker offers a teaser with two selections on a single game. New England is given +3.5 handicap against Green Bay, whereas the Over/Under line is set to 35.5 points. If you play the two bets together as a parlay, the odds will be around 2.60 (8/5), but if you play a teaser, the odds are just 2.00 (1/1). This is because you are given six points to adjust the spread.
If you bet on New England, they are now +9.5 (3.5 + 6) underdogs, but you can also use the six points to adjust the spread on Over/Under market. If you want to bet on over, the line is 29.5 (35.5-6).
