What are teaser bets?

Teaser bets are common in football and basketball wagers. The point spread is teased by additional points in the player’s favor on more than one game. In football, the teaser lines will most likely be by 6, 6.5 or 7. Basketball lines are teased by 4, 4.5 or 5 points. Teasers do come at a cost for the player.
