What Is a Wong Teaser? A Plain-English Guide
If you've spent any time reading about NFL teasers, you've run into the term "Wong teaser." It's the most widely recommended teaser strategy in NFL football betting, and it's where most serious teaser bettors start. Here's what it is, why it works at times, and where my approach does better.
First, what is a teaser?
A teaser lets you combine two or more teams into a single bet (like a parlay). But, unlike a parlay, a teaser bet allows you to move the point spread in your favor in exchange for a smaller payout than a traditional parlay. In a standard 6-point NFL teaser, a favorite of -7.5 becomes -1.5, and an underdog of +2.5 becomes +8.5. The catch: every game in the teaser has to win. If one leg loses, the whole bet loses.
Where the name comes from
The Wong teaser strategy is named for Stanford Wong, a gambling author who laid it out in his 2001 book Sharp Sports Betting. His insight was simple: not all points are worth the same in the NFL. Because of field goals and touchdowns, far more games end with a margin of exactly 3 or 7 than any other number. Moving a spread through both of those numbers is worth much more than moving it the same six points anywhere else.
The Wong teaser rules
A Wong teaser uses 6-point teasers only on games that fall into two narrow ranges:
- Favorites of -7.5, -8 or -8.5, teased down to -1.5, -2 or -2.5
- Underdogs of +1.5, +2 or +2.5, teased up to +7.5, +8 or +8.5
In both cases, the six points carry the spread across both 3 and 7. A -7.5 favorite that only needed to win by 8 now only needs to win by 2. A +2.5 underdog that could only lose by 2 can now lose by 8. Games at other numbers (a -7 favorite or a +3 underdog, for example) don't qualify, because the additional six points don't cross both key numbers.
The break-even math
Because every leg must win, a teaser needs a high win rate per game to be profitable. At the traditional price of -110 for a 2-team, 6-point teaser, each leg has to win about 72.4% of the time just to break even. Many sportsbooks now charge -120 for the same bet, which pushes the break-even to about 73.9%. Historically, Wong-qualifying games have won at roughly that level or a bit better, which is why the strategy became popular, and also why sportsbooks raised their teaser prices once they caught on to the Wong strategy.
Why the Wong strategy alone can be difficult to implement
- Patience with the line. A half-point matters. A favorite at -7 or an underdog at +3 does not meet the narrow range of eligible games even though it's just a half-point away. It also can be tempting to grab the line early in the week when it sits in the right range, even though the line may shift out of the range by game time.
- Discipline. Some weeks offer plenty of qualifying games, and some weeks very few. The strategy only works if you are disciplined enough to pass on games that don't fit the exact range of lines.
- Price shopping. The difference between -110 and -120 may look small, but it raises the win rate you need from about 72.4% to 73.9%. So in the long run, the payout your sportsbook offers matters as much as the games you pick.
Is it the whole story?
The Wong teaser is a sound starting point. But it's built on one idea, crossing 3 and 7, applied the same way to every game. In my experience, that leaves opportunities on the table. My strategy takes a more comprehensive look at the game conditions and the odds, which I explain in a separate post called Beyond the Wong Teaser: Why Crossing 3 and 7 Isn't the Whole Story.
