As soon as one ball reaches the skull, the others follow and the player loses a life. The player can carry two balls at a time and can switch at any time. The objective of Zuma is to eliminate all of the balls rolling around the screen along a given path (the path is clearly visible in all of the levels except for the last level) with other balls before these balls reach the yellow skull structure, which will open to varying degrees as a warning of oncoming balls. Many sequels were developed: Zuma Deluxe, Zuma's Revenge!, and Zuma Blitz on Facebook. Zuma is a fast-paced tile-matching puzzle game developed by PopCap Games.
