Reversi Gems

Very nice thinking game. You have to light up all the gems or make them all dark. Play the different modes and try and test you skills. Left click with the mouse to touch a gem. Touching a gem will change its color and the colors of all those around it in a + shape. If you touch a unlit gem it will light up and those around it will light up or dim depending on what they were before and vice versa Try and think a few moves ahead and predict the shapes that will come if you touch a gem. Play with your friends and figure out all the shapes.
