Here the view of a cube is given. The cube consists of 27 (3x3x3) or 64 (4x4x4) smaller cubes. Each of them is either black or white (dark or light). The cubes are semi-transparent: If you look at a position where all cubes are white it looks white, white and black cubes together look gray and a position where all cubes are black looks black. The view (from all 6 sides) of the large cube is displayed on the right side.
Your task is to find out the colors of the smaller cubes. Click first on the large black or white field to choose a color (or press "D" or "L") and after that click on the fields which (you think) have the same color. If you make a mistake then the game is over. The game is solved when the colors of all fields are found out.

You can also use the arrow keys to manage the game. To press a field use the space bar.
