In Balls & Walls you play as the heroic White Arrow whose quest is to defeat the Evil Octahedrons. Build walls around them and claim empty spaces, until, bit by bit, you capture at least three-quarters of the screen... and then it's payback time.This game is a spin-off of good old QIX, but now your wall building is not confined to mere four (or eight) directions. Go in any direction you want!To control the Arrow, touch anywhere on the screen and move your finger in the desired direction. If the game feels too slow or too fast, you can use volume keys to adjust its speed.
