There's apparently not enough stuff to do in World of Warcraft to make people happy to play in the best selling MMO so casual game maker Popcap Games is getting ready to release an add-on for the game that will allow players of Blizzard's title to play the hugely popular puzzle game Bejeweled inside the title.

Our sister site WoWinsider has a hands-on preview of the Bejeweled add-on for World of Warcraft which is scheduled to be released for free on Tuesday. The add-on, which is not officially endorced by Blizzard, will have some World of Warcraft sounds and art incorporated into the game and will even interact with World of Warcraft itself in small ways.
