CUBE2D is a two dimensional puzzle using the Rubik's Cube algorithms. Each side of the cube is painted in different colors; red, blue, orange, white, yellow and green. 9 panels make up each side of the cube so there are 54 panels in total. The players match the colors by tapping on the panels to move them around. How to play: By tapping on the panels adjacent to a panel, 12 or 21 panels move. Along the four sides of the 6 center panels, the color of the adjacent side (when in cube) is indicated. By matching the colors of the four sides of the center panel with the siders of the surrounding panels, the puzzle is completed. However, it is extremely difficult to complete it.
