A version of puzzle game favorite Bejeweled will be offered as an add-on for Blizzard’s massively multiplayer game World of WarCraft. Publisher PopCap Games created the official version after it became aware of the popularity of unofficial clone Besharded being used in the game. According to a report on consumer website Joystiq, PopCap tapped Besharded creator Michael Fromwiller to create an official version of the game. The application was originally intended to kill time during long raids, farming sessions, flights, and other only semi-interactive activities. The add-on will be offered free of charge, and has apparently been developed after only limited contact between Blizzard and PopCap Games. The add-on offers classic, timed, and "flight" modes, a customizable user interface, and a persistent high score table. A Bejeweling "tradeskill" also ranks up with player’s achievements.
