How to Play

You and your opponent share one board, split into two zones. Place pieces to clear lines and push the boundary into their half — drive them off their edge to win.

Your Field

You are the light zone. Your dark pieces fall through the light and land on the dark boundary.

Gap Creation

When your piece locks, its cells flip to the opponent's color — every piece you place hands them ground to move through.

Penalty

Seal a gap the opponent can't reach and those cells auto-fill, charging your penalty meter. Fill it and you lose a line — shoved back toward your edge.

Line Clear

Fill an entire row dark to clear it. The boundary shifts toward the opponent. Push them off to win.
