BlackBerry is aiming to boost uptake of apps for its BlackBerry 10 operating system by offering a selection of premium apps for free and others with discounts in its app store.

According to the Inside BlackBerry blog, the 25 Days of Gifts giveaway in BlackBerry World will offer users one premium BlackBerry 10 app, game or movie each day between 1 December and Christmas Day.

The offer started with the Angry Birds Seasons game, normally priced at $0.99, being given away for free. The second day giveaway is for video content, with Jingle All the Way available in the US, Home Alone 2 in Canada and an episode of Top Gear for UK consumers.

A separate Hello Winter $0.99 sale, meanwhile, will offer content at a discounted price during the entire month of December, according to reports.
