Build is a 3D physics game similar to Tetris. The object of the game is simply to build the highest tower possible by stacking tetrominoes. Three tetrominoes will appear at the top of the screen and you must place them so that they don't fall off of the stage. Unlike Tetris, the shapes don't stack perfectly and are subject to the laws of gravity. Don't forget to purchase power-ups and new themes with the gems that you collect.
