LawsuitThe Zuma concept is not new. Popcap borrowed it from Mitchell Corp.'s 1998 arcade game Puzz Loop/Ballistic. In 2004, President Roy Ozaki intended to file a lawsuit against Popcap for IP infringement. The outcome is not known. Mitchell did however rework the game concept in the 2006 Nintendo DS game Magnetica.
