Batti Gull (Lights Off)

Batti Gull means light's gone or light's off, and that's what you have to do in this puzzle game. You have to switch all the lights in the board OFF. It sounds simple, but its not. The twist is whichever light you toggle(i.e either switch OFF/ON) it will toggle the left,right,top and bottom lights as well.

The game consists of 30 levels, initial levels are quite easy but it gets tougher and tougher as you progresses levels.
