Research In Motion said software development kit (SDK) maker Marmalade will offer licenses to mobile applications developers to bring their games and apps to the BlackBerry 10 smartphones and PlayBook tablets.

The offer encourages Marmalade developers to bring their games and applications to the BlackBerry PlayBook and BlackBerry 10 platform.

Initially available for a limited period, qualified developers who register will receive a Marmalade SDK license for the BlackBerry platform as well as a BlackBerry PlayBook tablet. Once the developer has published their app on the BlackBerry App World storefront, they can unlock the full cross-platform power of the Marmalade SDK by upgrading to the Marmalade Indie licence for free.

The Marmalade SDK also offers developers the option to develop natively with C/C++ or create hybrid apps in HTML5, targeting mobile devices as well as desktop and laptop computers.

The offer is designed to attract content to the BlackBerry 10 platform.

RIM says that its BlackBerry App World is one of the most profitable mobile app stores for developers, with more than 6 million applications downloaded every day. According to market analysis and strategy firm Vision Mobile, BlackBerry developers generate, on average, 4 percent more revenue per app per month than iOS developers and almost 40 percent more than Android developers.
