Barricade
Lay trail as you move - crash into a wall, the border, or your own trail and you're out. Trap your opponent first to win. You are always the red trail.
Your turn (red) - move with arrows or tap a green cell
A trail-blazing strategy game where you leave a wall behind as you move, trying to trap your opponent in a shrinking space before they trap you - simple rules, but genuinely strategic as the available space narrows.
