Zuma is a trial version of the match-3 puzzle game developed by PopCap Games. In this popular and highly addictive arcade game, you control a frog that can spit out balls of different colors. Once these launched balls match at least two of the same color from the moving line of balls, they explode out of play.
PopCap asserted that Zuma was "not an exact clone", with founder Jason Kapalka saying that he was "happy" with the idea of games being cloned by other developers, so long as the new version added to the gameplay of the game it had copied.
