⚽ Free Kick Simulator

Drag from the ball to aim, release to shoot. Beat the wall, score under the bar.

I built this because I've watched way too many free kicks taken suboptimally over the years. The physics here is real — numerical integration, quadratic air drag, actual ball mass and dimensions — so please go try the optimal shot irl.
