Card football. Call the play, set the coverage, watch fourteen players run it out on a real field.

PLAY FREE · IN YOUR BROWSER · NO SIGN-UPYou pick the play. The opposing coach picks the coverage. Concept beats concept the way it does on a real call sheet — quick game punishes an all-out blitz, four verts dies against quarters. Every coach on the ladder has their own tendencies, and they scout you as the game goes on.
Nothing is rolled on a table. Routes are waypoints, coverage is real zone geometry, and every tackle is an attribute duel resolved tick by tick. Fatigue and injuries carry across a match.
The next one is already in the engine.
