A 10-point lead means very different things in the first quarter and the final minute. Win probability turns score and clock into a single live percentage.

Presets
Win probability turns the score and clock into a live percentage. Early on, even a big lead is fragile because plenty of scoring remains; late in the game, the same lead is nearly safe because the uncertainty has shrunk. Modeling the remaining margin as a shrinking random variable produces the classic curve that broadcasts now show on screen.

How it works
Win-probability models treat the remaining scoring margin as a random variable whose uncertainty shrinks as the clock runs down. Early, even a large lead is fragile because much scoring remains; late, the same lead is nearly decisive. The resulting curve is the win-probability graph now standard on sports broadcasts and betting screens.

Is this win probability sports model tool really free?▾
Yes. Live Win Probability runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?▾
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?▾
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?▾
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
