"Fill 75" is a game like jezzball, where you have to fill 75% of the screen.
At first choose a color (Green, Orange, Purple) Next a type of line (horizontal or vertical).
Next touch the screen, and release it when no ball from the same color are crossing the line.
If you fill an average of 75% of the screen with the 3 colors you pass to the next level.
Balls can hit each others whatever their color are.
If you touch a ball you lost a life.
If you lost all your life, you lost.
