About this game

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.
- No ads ever
- No internet connection required
- No sign-in required to play
- No paywalls or in-app purchases

Just you and the balls.

How to play
- Swipe left, right, up, or down to draw a line
- The empty side gets filled, the side with balls stays open
- Fill the arena to the target percentage to clear the level
- Every level adds another ball and raises the target

Three difficulties
- Easy: a gentle introduction that ramps up gradually
- Medium: for players who want a challenge
- Hard: fast balls, steep targets, no mercy

Features
- Endless levels that keep getting harder
- Local high score leaderboard
- Google Play Games leaderboards and achievements (optional, offline play fully supported)
- High-contrast mode for better visibility
- Sound and vibration controls
- Resume a game you left mid-session
