Cube of Concentration

The object of the game is to match symbols on a cube. Each of the four sides of the cube has nine squares on it, each with a different symbol. Click on a symbol to select it. Click on a second symbol to try to match it. When you find a match, the symbols will be removed from the cube. Remove all the symbols to win. Click on the arrows to rotate the cube. Click the Restart button to start over. Clicking the Colors button will make all of the symbols black and white. Clicking the Hidden button will reveal all of the symbols all of the time and thus make the game easier.
