How to Use This Calculator
Enter favorite spread lines for two teaser legs (negative numbers). The tool adds six teaser points in this demo and flags whether either teased line crosses classic NFL key-number windows (−3 to −10 region in the code’s heuristic).
Both legs favorites
Use the favorite-side spread as signed negatives (e.g. −7.5).
6-point teaser
Implementation moves each leg by +6 toward the bettor for illustration.
Key number flag
Output text hints when lines cross important thresholds—still verify manually.
Not payout odds
Use Teaser calculator for price multiplication.
Key Numbers
Wong teasers target crossing 3 and 7 in football because scoring margins cluster there. This tool is a quick visualization of teased lines, not a full simulation of EV.
Examples
Example 1 — Defaults −7.5 / −7.5
Teased lines ≈ −1.5 each after +6. Check crossing message in the live readout.
Example 2 — Different legs
−6 and −4.5 tease to +0 and +1.5—see how key-number language changes.
Example 3 — Basketball
Key numbers differ—treat NFL-style heuristics cautiously for NBA teasers.
