Australian developer Halfbrick Studios has seen more than 14 million downloads for Jetpack Joyride
since the action game launched for iOS devices in August 2011.
Though Jetpack Joyride
went free-to-play in mid-December, Halfbrick saw $1 million in paid sales for the game before that switch. It also estimates that 5-10 percent of its 14 million players spend at least a dollar through its in-app store, according to a report
from news site Joystiq.
Halfbrick's Fruit Ninja Kinect
, a motion control version of its popular smartphone title, is also enjoying success after selling half a million copies on Xbox Live Arcade. The downloadable game released last August is currently priced at 800 Microsoft Points ($10).
