A new twist on the gameplay provided by Tetris, Polycubes features a 3 dimensional take to the popular classic. In this game a random sequence of polycubes (3-D pieces composed of cubes) are falling on a 3-D gamefield. The goal of Polycubes is to create complete layers of blocks without any gaps. When one of these layers are created, it disappears, and any blocks above the completed layer will drop down a step. As time goes on, the pieces start falling faster and faster to increase the difficulty.
