Click anywhere, if you click on a cluster it will turn green. if you are near one it will turn yellow. If it turns green and the cluster found didn't change then keep clicking the green ones around it until it does change. Note: Greens by each other will not count and sperate clusters, and only one green in a cluster will change the Clusters Found. You get 40 guesses, and there are 300 total squares, if you have a computer make sure to click so you here the click or else it will count it as 2-5 clicks/guesses. Have Fun Playing!
