Chandelier hitmaker Sia has announced the launch of a new game, Bob Job, available on the App Store and on Google Play, which involves players matching rows of bobs, dogs and unicorns.

The game, designed and soundtracked by Sia, is in aid of Best Friends Animal Charity, which helped pioneer the no-kill movement in US animal shelters, and coincides with the digital deluxe version of her album 1000 Forms Of Fear, which was released May 4.
