Bangalore’s Indigo 91.9 turned seven years old on Thursday and created a Facebook app to let listeners celebrate the occasion.

The Indigo Smash Hits app is not a music quiz like you might expect, but an animated game which involves smashing cakes over the heads of Indigo’s RJs.

You can sign up just like any other app from the Indigo Facebook page.

The station is offering 12 different prizes including “couple” passes for its upcoming birthday bash to the top scorers.

Indigo 91.9 operates in Bangalore and Goa and runs a contemporary international (English) music format.

The stations are owned by Jupiter Capital.
