Jetpack Joyride studio Halfbrick has revealed that switching the game to a free-to-play model saw a huge increase in downloads, increasing revenue levels.
The game made around $1 million when it was released as a $1 game, but, since switching to a free-to-play model, has been downloaded 13 million times. Around 5-10 per cent of those downloads result in expenditure of at least $1, says Halfbrick.
That level of engagement has been enough to increase the revenues of the product.
The developer revealed the figures whilst speaking to Joystiq at the DICE event in Las Vegas, also expressing satisfaction with the performance of Fruit Ninja Kinect, which has sold 500,000 copies.
