The unicorn-filled online world is an outlandish, Gaga-style version of the hit game FarmVille.
Starting on Tuesday, May 17, fans can stream a new track from her album, Born This Way, every day until May 19.
Then, from May 20-23, gamers can unlock parts of tracks and remixes of songs.
'Everything we've created has been in collaboration,' said Gaga in a statement about the game, which is made by California-based company, Zynga.
'From giving players a listen to unreleased songs as a reward for game play within 'FarmVille' to creating daily experiences in 'Words With Friends' that embody the album's messages and songs. We've had a lot of fun developing this program as a unique celebration of the album.'
The first new song to be launched in GagaVille is Marry the Night, a dance tune about the celebrations that happen after dark.
