NFL Teasers: Buying Points Smartly to Maximize Your Profits

The Chiefs are favored at -8.5. You think they'll win, but covering 8.5 points feels risky.

What if you could turn that -8.5 into -2.5?

That's exactly what a teaser lets you do.

NFL teasers are one of the rare bets where the bettor can hold a mathematical edge over the sportsbook — as long as you use them correctly. The key: Key Numbers 3 and 7.

What Is a Teaser?

The Definition

A teaser is a type of parlay where you "buy" extra points on each selection in exchange for reduced odds.

Standard NFL Teaser: +6 points on each spread
Minimum: 2 selections (legs)
Typical odds (2 legs): ~1.91 (-110)

A Concrete Example

Without a teaser (standard parlay): - Chiefs -8.5 at 1.91 - Ravens -3.5 at 1.91 - Parlay: 1.91 x 1.91 = 3.65

With a 6-point teaser: - Chiefs -8.5 + 6 = Chiefs -2.5 - Ravens -3.5 + 6 = Ravens +2.5 - 2-leg teaser: 1.91 (-110)

You "bought" 6 points on each selection, but the odds dropped from 3.65 to 1.91.

Types of Teasers

Type	Points Bought	2-Leg Odds	3-Leg Odds
Standard	6 pts	1.91	2.60
Super	6.5 pts	1.77	2.30
Monster	7 pts	1.67	2.10
Big	10 pts	1.45	1.70

The 6-point teaser is the most common and most profitable.

Why NFL Teasers Work

Key Numbers

In the NFL, certain margins of victory occur far more frequently:

Margin	Frequency	Cumulative
3 pts	~15%	15%
7 pts	~9%	24%
6 pts	~5%	29%
10 pts	~5%	34%
4 pts	~4%	38%

Margins of 3 and 7 account for ~24% of NFL games.

The Teaser Logic

A 6-point teaser lets you cross through these Key Numbers:

-9 -> -3 (crosses 7 and 3 downward)
-8 -> -2 (crosses 7 and 3)
-7.5 -> -1.5 (crosses 7 and 3)
-3.5 -> +2.5 (crosses 3)
+1.5 -> +7.5 (crosses 3 and 7)
+2 -> +8 (crosses 3 and 7)

The Mathematical Edge

When you cross through both 3 AND 7:

Original spread: -8
Teased to -2: You avoid losses on margins of 3, 4, 5, 6, 7

Probability gain: ~20-25% additional win rate
Cost: Reduced odds (from ~1.91 individual to ~1.91 combined)

The probability gain often exceeds the cost of the reduced odds.

The Wong Teaser

What Is It?

The Wong Teaser (named after Stanford Wong, author of "Sharp Sports Betting") is the most profitable teaser strategy. It consists of:

1. Using 6-point teasers
2. Only selecting spreads that cross both 3 and 7
3. Only placing 2-leg teasers

Spreads Eligible for the Wong Teaser

Original Spread	Teased +6	Crosses 3?	Crosses 7?	Wong?
-7.5, -8, -8.5, -9	-1.5 to -3	Yes	Yes	YES
+1.5, +2, +2.5	+7.5 to +8.5	Yes	Yes	YES
-3.5, -4, -4.5	+2 to +2.5	Yes	No	No
+7, +7.5	+13, +13.5	No	Yes	No
-1, -1.5, -2	+4 to +5	Yes	No	No
-10, -10.5	-4, -4.5	No	Yes	No

The Two Wong Teaser "Sweet Spots"

Sweet spot #1: Favorites -7.5 to -9

-7.5 -> -1.5 (crosses 7, 6, 5, 4, 3)
-8 -> -2 (crosses 7, 6, 5, 4, 3)
-8.5 -> -2.5 (crosses 7, 6, 5, 4, 3)
-9 -> -3 (crosses 7, 6, 5, 4, LANDS on 3)

Sweet spot #2: Underdogs +1.5 to +2.5

+1.5 -> +7.5 (crosses 3, 4, 5, 6, 7)
+2 -> +8 (crosses 3, 4, 5, 6, 7)
+2.5 -> +8.5 (crosses 3, 4, 5, 6, 7)

The Math Behind the Wong Teaser

Required Win Rate

For a 2-leg teaser at -110 (1.91):

Break-even = 1 / 1.91 = 52.4%

But it's a 2-leg parlay:
Each leg must win at: sqrt(0.524) = 72.4%

Each selection needs ~72.4% chance of covering to break even.

Wong Teaser Win Rates

Historical data on Wong-eligible spreads:

Original Spread	Teased Win Rate at +6
-7.5	76%
-8	77%
-8.5	78%
+1.5	74%
+2	75%
+2.5	76%

Average: ~76% — above the 72.4% break-even threshold.

Expected ROI

Win rate per leg: 76%
Teaser win rate (2 legs): 0.76 x 0.76 = 57.8%
Odds: 1.91

EV = (0.578 x 1.91) - 1 = +10.4%

A well-executed Wong Teaser has a theoretical ROI of ~10%.

Comparison with a Straight Spread Bet

Bet Type	Win Rate	Odds	EV
Straight spread -8	52%	1.91	-0.6%
Wong Teaser (-8 + another Wong)	57.8%	1.91	+10.4%

The teaser turns a slightly negative bet into a highly positive one.

The Wong Teaser Rules

Rule #1: Only Eligible Spreads

Favorites -7.5 to -9
Underdogs +1.5 to +2.5
Everything else: skip

Rule #2: Only 2 Legs

Teasers with 3+ legs have negative expected value:

Legs	Required Win Rate per Leg	Realistic?
2	72.4%	Yes (Wong ~76%)
3	78.5%	Borderline
4	82.3%	Too difficult

Rule #3: Only at -110 or Better

Teaser at -110 (1.91): Acceptable
Teaser at -120 (1.83): Marginal
Teaser at -130 (1.77): No [value](/guides/value-betting-only-concept-that-matters-profitable-betting/)

Rule #4: NFL Only (Not NBA)

NBA teasers don't work nearly as well:

Sport	Key Numbers	Profitable Teaser?
NFL	3, 7 (very frequent)	Yes (Wong)
NBA	None dominant	No
NCAAF	3, 7 (less frequent)	Marginal

Rule #5: Avoid the 0 (Pick'em)

Don't tease to 0:

-6 teased to 0 (frequent pushes)
+6 teased to +12 (no additional value on the 7)

When to Avoid Teasers

Avoid #1: Non-Eligible Spreads

-3 -> +3: Crosses 3 but not 7 -> Not Wong
-10 -> -4: Crosses 7 but not 3 -> Not Wong
+7 -> +13: Doesn't cross 3 -> Not Wong

Avoid #2: "Off Numbers"

Some spreads fall between Key Numbers:

-5 -> +1: Only partially crosses
-6 -> 0: The 0 creates frequent pushes

Avoid #3: When the Odds Are Bad

Teaser at -130: Break-even = 76.5% per leg
Wong win rate: ~76%

EV ~ 0% -> No value

Avoid #4: Games with Low Totals

Defensive games (total < 40) produce tighter results:

Total 38: More wins by 3-6 points
-> The teaser has less value (you're crossing rare margins)

Avoid #5: Forcing a Teaser

"I want to do a teaser, I'll take the best available spreads" -> Wrong
"I only do a teaser IF I have 2 Wong-eligible spreads" -> Right

Teaser Variants

The 6.5-Point Teaser

Some books offer 6.5 points at reduced odds:

Points	2-Leg Odds	Advantage
6	1.91	Standard
6.5	1.77	+0.5 pt but -7% odds

Generally, the standard 6-point teaser is better — the half-point doesn't offset the reduced odds.

The 7-Point Teaser

The "monster teaser" offers 7 points:

-8.5 -> -1.5 (instead of -2.5)
Odds: ~1.67

The 0.5 pt gain is marginal
The odds drop (1.91 -> 1.67) is significant

The 7-point teaser is only profitable if the odds are > 1.80.

The "Sweetheart" Teaser (10+ Points)

Some books offer 10-13 points:

-8 -> +2 to +5 (10-13 points)
Odds: 1.45-1.55 for 2 legs

Break-even per leg: 80%+
Nearly impossible to sustain

"Sweetheart" teasers are traps — avoid them.

The 3-Leg Teaser

If you find 3 Wong-eligible spreads:

3 Wong legs at -120 (1.83):
Break-even per leg: (1/1.83)^(1/3) = 78.5%

Wong win rate: 76%
-> Negative EV

Only do 3-leg teasers if the odds are exceptional (> 2.50).

The Week's Spreads

Game	Spread	Wong Eligible?
Chiefs @ Raiders	Chiefs -8	Yes — Favorite -8
Bills @ Dolphins	Bills -7.5	Yes — Favorite -7.5
Cowboys @ Eagles	Cowboys +2	Yes — Dog +2
Ravens @ Bengals	Ravens -3.5	No
Packers @ Lions	Packers +7	No
49ers @ Seahawks	49ers -5.5	No

Possible Teasers

Teaser #1: Chiefs -8 + Bills -7.5

Chiefs -8 -> -2
Bills -7.5 -> -1.5

Both cross 3 and 7: Perfect Wong

Teaser #2: Chiefs -8 + Cowboys +2

Chiefs -8 -> -2
Cowboys +2 -> +8

Both cross 3 and 7: Perfect Wong

Teaser #3: Bills -7.5 + Cowboys +2

Bills -7.5 -> -1.5
Cowboys +2 -> +8

Both cross 3 and 7: Perfect Wong

Which One to Pick?

You can't place all 3 (same team in multiple teasers). Here's how to choose:

Teaser	Your Confidence	Decision
Chiefs + Bills	Chiefs 78%, Bills 76%	Best
Chiefs + Cowboys	Chiefs 78%, Cowboys 73%	Good
Bills + Cowboys	Bills 76%, Cowboys 73%	OK

Also compare the odds via line shopping. Pick the 2 legs with the highest teased win rate.

The Result

Teaser: Chiefs -2 + Bills -1.5
Odds: 1.91 (-110)
Stake: $50 (2.5% of a $2,000 bankroll)

Results:
- Chiefs win 31-17 (margin 14) -- -2 covered
- Bills win 24-21 (margin 3) -- -1.5 covered

Profit: $50 x 0.91 = +$45.50

Bankroll Management for Teasers

Bet Sizing

Teasers are parlays — variance is higher:

Bet Type	Recommended Stake
Straight spread	1-2% bankroll
2-leg teaser	1-1.5% bankroll
3-leg teaser	0.5-1% bankroll

Frequency

Don't force teasers:

Week with 0 Wong matchups: 0 teasers
Week with 1 Wong matchup: 0 teasers (need 2)
Week with 2+ Wong matchups: 1 teaser
Week with 4+ Wong matchups: 1-2 teasers

Common Teaser Mistakes

Mistake #1: Teasing Every Spread

"I'll tease the 3 games I like" -> Wrong
"I ONLY tease Wong-eligible spreads" -> Right

Mistake #2: Teasers with 3+ Legs

"More legs = more potential payout" -> Wrong
"More legs = negative expected value" -> Right

Mistake #3: Accepting Poor Odds

"2-leg teaser at -130, good enough" -> Wrong
"2-leg teaser at -110 or nothing" -> Right

Mistake #4: Teasers in NBA or Other Sports

"NBA spread is -7, I'll tease it to -1" -> Wrong
"Teasers only work in the NFL" -> Right

Mistake #5: Forgetting About Correlation

"Teaser Chiefs -2 + Chiefs Under 47" -> Wrong
"No correlated bets in the same teaser" -> Right
