How do you get free gems from installing apps? Can't get one .
Click on Free Gems > Install and run the apps (other apps require other actions like completing a level in a game or making a purchase) > the free gems are usually automatically added to your gem total. If you do not receive any gems, click the 'Missing Gems?' link at the bottom right corner of the Tapjoy Free Gem offer window and follow instructions to report missing gems.
