What is Teaser?
A parlay-style bet where you adjust the spread or total in your favor on each leg in exchange for a worse price.
A 6-point teaser moves the line 6 points in your favor on every leg. Sounds great, but the price changes too. Typically from −110 per leg to roughly −120 or worse, and all legs still have to hit. Some teasers can be +EV at NFL key numbers (3 and 7) but most are not. The math is unforgiving once you stack legs.
