Format
Girl Group Wars follows the same format as many reality singing competitions. Each week there is a live show where the groups each perform an original song. After the show, the voting lines are opened for viewers around the world, and the next day the result show is aired. In the results show, the groups are split into two. One half are the groups who had the most votes and the other are the groups who had the least votes. The bottom two performing groups are then asked to "sing for their life" where they perform a cover of a well-known song and the judges choose who is eliminated.

Auditions
Auditions were held in six continents and over fifty countries over a span of six months.
