How to Play
You and your opponent share one board, split into two zones. Your dark pieces fall down; their light pieces rise up. Clear lines to push the boundary toward them — drive them off their edge to win.
Your Field
You play in the light zone. Your dark pieces fall through light cells and land on the dark boundary below.
Gap Creation
When your piece locks, its cells flip to the opponent's color — and vice versa. Every lock hands the other side new space to move through.
Penalty
Leave pockets of your own color cut off from your home edge and they seal — auto-filling and charging your penalty meter. Fill it and you lose a line, shoved back toward your edge.
Line Clear
Clear a full row of your color to shift the boundary toward the opponent. Bigger clears and combos push even further. Win when they have no room left at their edge.
