Mouse down to create a filler ball. It will continue to grow until it hits a bouncy ball (ouch!) or another filler ball. Press space to freeze all the bouncy balls (drains your freeze).

Filler is back with improved graphics, improved physics, three difficulties, and 100 challenges to keep you busy! Your goal is still the same: fill 2/3 of the level to advance. For added strategy, play the game on Normal and press space to freeze the balls in place.
