Concept rendering of a Gridball rally in a future arena: two Miami and two Rochester players, one in each quadrant, with four Officiators at the court sides

Four square grew up.

Own the Grid™.
Own the Game.

Gridball is a co-ed team sport evolved from four square. Four active players—two per team—share the Grid. Return the ball after one bounce, survive the rally, and turn control of the court into points.

Miami. A seventh-floor dance studio.

Before Gridball,
there was a box.

Tape on the floor. A ball. A line of students waiting to play. The idea started with a game that kept bringing people back.

The long game

A sport to play.
A league to build.

We see Gridball growing from local courts to a world-stage sport, with the NGL as its professional home. Clubs with their own identities. Collared kits. Purpose-built arenas. Fans who belong to something.

That is the long-term vision. The clubs, arenas, and championship experiences shown here are concepts. Our immediate next step is the first playtest.
