About this app
Draw lines. Fill the box. Survive.
FillTheBox is a simple but addictive arcade game. Swipe to draw a line across the arena, the side without bouncing balls gets filled in. Fill enough of the arena to advance to the next level. Don't let a ball touch your line while you're drawing, or it's game over.
No nonsense. No compromise.
