Splash! is absolutely new game designed only for phone with a motion control and a touch screen.

Your aim is save the white ball from the coloring. Don't let other balls to contact with white ball.
Touch the colored balls to stop them. Tilt the phone to move the white ball.
And beware the black ball - you can't stop it until it's color will not change.
Seems easy ... at first.

Enjoy excellent graphics and fascinating game play!
