A free NFL strategy simulator that runs in your browser. Every day everyone gets the same real late-game NFL drive: the real score, clock, timeouts, quarterback and receivers. You call every play, the tempo and the timeouts, and a Monte Carlo engine built on every NFL play since 2016 grades each call on win probability before the result is revealed. Then see how the real head coach's calls grade on the same scale. Practice, Survivor and friend challenges included. No sign-up.
