How to play

  • Build horizontal and vertical walls to isolate the bouncing balls from each other
  • If a ball collides with your wall while building, you lose a life
  • Continue playing until you run out of lives!


  • Arrow keys to move
  • Z to build a horizontal wall
  • X to build a vertical wall

There is also an alternate control scheme if you press ENTER then select TOGGLE CONTROLS:

  • Hold either Z or X and then press up/down to build a vertical wall or left/right to build a horizontal wall.
