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

Real frames from the running build, captured at phone width because that is the shape almost everyone will play it in.
Every pose the engine can draw — set, run, throw, catch, juke, dive, tackled, kick, celebrate — in eight team kits.
What it is
You pick the play, the opposing coach picks the coverage, and a deterministic sim resolves what happens between them.
Nobody on this field is real. Every player, coach and team in SPRAIN is invented — the names, the numbers, the tendencies — so the only thing you are up against is the call sheet.
You 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.
