Sia launching phone game inspired by bob hairstyle

Singer/songwriter Sia is using her trademark blonde bob wig for a good cause by launching a new smartphone game for charity.

The Chandelier hitmaker has taken to hiding her face during promotional appearances for her latest album 1000 Forms of Fear, and she often wears an oversized toupee as a mask.

On Tuesday (05May15), Sia announced her new project, called Bob Job!, a free-to-play mobile game, with proceeds going towards charity Best Friends Animal Society, which helps animals in distress.

In the game, players must make sets of three bobs, dogs or unicorns in a row before time runs out.

The Australian star helped develop the app with engineers at games studio Mass Threat, and the soundtrack includes hits from her latest album.

Sia follows in the footsteps of other celebrities who have found success with cell phone games, including Kim Kardashian, whose Kim Kardashian: Hollywood game has earned the reality TV star an estimated $20 million from sales.
