I love these little games. They take me out of myself and let me do something fun and relaxing for a whilte. This game is excellent for just this purpose. So if you like shiny diamonds and have a fast clicking finger, this game is surely for you.
Click on BEGIN. The screen will start to fill up with diamonds. What you need to do is click any set of diamonds that has at least 3 or more diamonds of the same color touching. So if you click on 3 yellow diamonds, they will disappear. You must find these color series and click them before the screen gets all filled out. They don't have to be horizontal or in a line, just touching each other.
