Poly Tower is a great challenging game. All you need to do is to build a tower with the falling objects as high as possible. Random objects fall from the top of the screen and you need to control them.
And now the challenging part comes! You even need to be careful about the color of the objects. Intense blue means that the object is smooth while intense red means it is bouncy. Lighter objects are see through and heavier ones appear more solid.
You can commit your score and let the competition begin!
