Quick answer: A teaser bet is a parlay-style wager where you adjust point spreads or totals by 6, 6.5, or 7 points in your favor across multiple legs — in exchange for a reduced payout. Like a parlay, every leg must win for the teaser to cash. Unlike a parlay, the line itself moves in your favor, making each leg easier to win. Teasers are most popular in the NFL.
A Worked Example
You build a 2-team 6-point NFL teaser at -110: Chiefs -7 becomes Chiefs -1, and Eagles +3 becomes Eagles +9. You wager $110. The Chiefs win by 4 (covering the new -1) and the Eagles lose by 5 (covering the new +9). Both legs hit. You collect $100 profit.
The Math Behind Teasers
A 6-point NFL teaser requires each leg to win at roughly 72% to break even at -110 odds. Standard NFL spreads are calibrated to 50% — so the 6 points must convert each leg from coin flip to 72% winner. Crossing key numbers 3 and 7 is what historically made the Wong teaser profitable.
Why the Edge Has Shrunk
Sportsbooks have responded to Wong teaser players by widening prices on tight underdogs (+1.5 to +2.5) and tight favorites (-7.5 to -8.5). Many books now charge -120 or -130 on these legs. Some books explicitly ban Wong-pattern teasers.
Teasers vs Sharp Player Props
For data-driven bettors, the highest-edge market is no longer NFL teasers — it’s player props. PropsBot.AI’s High ROI Signal posts 31.7% verified ROI on 101,881 graded MLB player props — well above any historical teaser edge.
Common Teaser Mistakes
First: teasing big favorites that don’t cross key numbers (e.g., -10 down to -4). Second: teasing low totals where 6 points doesn’t matter much. Third: combining 4 or 5 legs in a teaser. Fourth: teasing primetime games on recency bias.
Frequently Asked Questions
How does a teaser bet work?
You select 2 or more games. The sportsbook applies a fixed point adjustment in your favor. All legs must win at the new adjusted line. Payout is fixed — typically -110 to -120 for a two-leg 6-point NFL teaser.
What is a Wong teaser?
A Wong teaser is an NFL 6-point teaser strategy: tease underdogs of +1.5 to +2.5 up to +7.5 to +8.5, or favorites of -7.5 to -8.5 down to -1.5 to -2.5. The strategy historically returned positive EV by crossing key numbers 3 and 7.
What sports allow teasers?
NFL is most common because of discrete scoring (3-point and 7-point key numbers). NBA also offers teasers, typically with 4 or 4.5 points. MLB and NHL teasers are rare.
Are teasers a good bet?
In general, no — most teasers carry an implied house edge of 15-25%. The exception was the historically positive-EV Wong teaser, but most books have tightened these prices.
What’s the difference between a teaser and a parlay?
A parlay uses original lines for each leg. A teaser moves lines in your favor across all legs in exchange for a smaller payout.
