How to promote the game on facebook?

We recently published application on facebook, now we do not know how to promote it.
Anybody can help to promote the game on facebook?

The main thing you need is the game, if the game is good you will get users very fast, it will go viral. But for the gameā€¦ it depends how good you are at making them, there would be lots of graphic design, music, and coding work to do. And also Advertise your game on facebook, make facebook accounts and add freinds, start a group or 2 about your game and advertise the group. You can market your game on facebook alone.
