Wong teasers: crossing the 3 and the 7
A Wong teaser is a 6-point, two-team NFL teaser that moves each side across both 3 and 7. That means favorites of -7.5 to -8.5 and underdogs of +1.5 to +2.5. Most NFL games end on those margins.

Key takeaways
- The edge comes from crossing both key numbers.
- Totals and basketball do not have the same key numbers.

Our own sorting of 6-point moves.
Why 3 and 7 carry the weight
NFL scoring comes in 3s and 7s, so a lot of games end on margins of exactly 3 or 7. A field goal decides many close games, and a touchdown with extra point decides many others. Points on those two margins are worth far more than points on, say, 5 or 11.
When you move a -7.5 favorite to -1.5, you buy every final margin from 2 to 7. That window includes both 3 and 7, plus many 4s and 6s. When you move a -6.5 favorite to -0.5, you also get 6 points, but only one key number, and you spend points on margins that rarely land.
Bettor and author Stanford Wong described this in his 2001 book on sports betting. Sportsbooks have since raised teaser prices and changed lines, so the classic spots now win by a smaller margin, if at all, at some books.
Break-even per leg by price
| Teaser price | Ticket must win | Each leg must win |
|---|---|---|
| -110 | 52.4% | 72.4% |
| -120 | 54.5% | 73.9% |
| -130 | 56.5% | 75.2% |
| -140 | 58.3% | 76.4% |
Each leg chance is the square root of the ticket chance, assuming independent legs.
How the break-even is worked out
A two-team teaser at -120 risks $120 to win $100. To break even you must win 120 out of 220 tickets, or 54.5%. Both legs must win, so each one needs about 73.9%, because 0.739 times 0.739 is about 0.545.
Public studies of past NFL seasons have found Wong legs covering in the mid-70s percent range, close to or slightly above that line. That is a thin edge. A small change in price, such as -130 instead of -120, can turn a winning spot into a losing one.
Three-team teasers often pay about +160 to +180 for 6 points. At +160 each leg needs about 73.7% to break even, which is close to the two-team number. Larger teasers add more legs, and every extra leg is another way to lose the ticket.

Favorites -7.5 to -8.5, dogs +1.5 to +2.5.
Step 02
Check the price

Step 03
Look at the total
Lower totals tend to help the legs.
Step 04

Step 05

Prices and lines differ.
When the edge fades
Wong spots work best on games with low totals, near 44 or less, because fewer points mean a 6-point move covers a larger share of outcomes. High totals spread final margins out and make every point a little less valuable.
Rule changes also matter. The NFL moved the extra-point kick back in 2015, and two-point tries changed how often games land on 7. Books watch these trends and price teasers to protect themselves, so many now offer worse odds on 6-point NFL teasers than they did in the 2000s.

Questions before and after you play
A 90-second guide cannot cover every table moment. Tap a group, then a question — answers are short paragraphs, not one-liners.
01Basics
What is a Wong teaser?
A two-team, 6-point NFL teaser where each leg moves across both 3 and 7. That means favorites of -7.5 to -8.5 and underdogs of +1.5 to +2.5.
Who is Wong?
Stanford Wong, a gambling author who wrote about these teasers in his 2001 book on sports betting. The name stuck in betting circles.
Do Wong teasers work in college football?
Less well. College margins are more spread out, so 3 and 7 land less often and the 6 points buy less.
02Math
What win rate does each leg need?
About 72.4% at -110 and 73.9% at -120 for a two-team teaser, assuming the legs are independent.
Why not tease a -3 favorite?
Moving -3 to +3 crosses 3 but not 7, and it uses points on the zero margin, so it buys fewer common results.
Can I tease a total?
Yes, but NFL totals do not cluster on key numbers like sides do, so teased totals are usually worse value.
03Rules
What happens if one leg pushes?
Most books drop the pushed leg. A two-team ticket may then be graded as a straight bet or become void, so check the house rules.
Are teasers legal everywhere?
Licensed US sportsbooks in most states offer NFL teasers, though prices and limits differ by operator.
Why do books price teasers so high now?
Bettors used these spots for years, so books raised prices to around -120 or worse to cover the risk.
