Cube of Concentration

Deep in the ancient Mayan ruins, adventurers risked their lives to bring back this rare and sacred artifact. But they were unable to unlock its mysteries (adventurers aren't very patient folks). Now it is up to you to match the mysterious symbols and solve the puzzle. Oh, and if you believe that, the yellow side tastes like lemons if you lick your screen.

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.
