Why can't I play Candy Crush on Facebook on my Blackberry Torch?
BlackBerry Torch can't run this game as it's not available for the BlackBerry platform. Also, the device does not have support for Adobe Flash and since the Facebook version of the game uses Adobe Flash, you will not be able to play this game.
You CAN install Candy Crush to the Blackberry. Read this tutorial: http://candycrushblackberry.com
Note: This will not work for the Torch, only the newer BlackBerry phones.
