In a teaser, since you are buying points and moving the point spread in one direction, your payout for a single selection is much lower than it would be if you were just betting the regular point spread on a side – which is often offered around -110. Since teasers must include multiple bets (two or more legs), all teaser bets are parlays, meaning that each individual leg must be graded as a win in order for your teaser parlay to be graded as a winner.
It is essentially an exchange of points for volume. Teasers give sports bettors the ability to move the line on a side, but at the cost of smaller payouts and with the agreement that their bet must include multiple legs.
