Zuma

Your objective in Zuma to eliminate all of the balls rolling around the screen along the path with other balls before these balls reach the yellow skull structure, which will open to varying degrees as a warning of oncoming balls. As soon as one ball reaches the skull, the rest follow and the player loses a life. When three or more of the same color come in contact, they explode, possibly triggering other explosions as part of a chain reaction. (Copied & Edited From Wikipedia)
