we used to play this game as a kid.
and was tempted to google it..
here is what it says,
"Initially, all s'sevaks will stand at one end of the area and all face one direction, with the catcher standing at least three metres in front of the s'sevaks. The s'sevaks will be standing in a semi-circular fashion, so they are equally same distance away from the catcher. When kuru is given, the s'sevaks will shout out "Bhai Bhai Kitna Kitna Pani Hey?". The catcher will reply "Itna Itna Pani Hey", and move his hands along his body to indicate the level of the water. This question and reply will continue until the catcher indicates the water level to be above his head, at which point the catcher will turn around and chase the s'sevaks. If he catches a s'sevaks before he reaches a pre-defined point then that s'sevak will become the catcher, otherwise the catcher will retain his role."
Basically, I think that is what we used to play, all girls wuld circle arond the one who is giving the den (as we used to say),, and as mentioned above, the others would ask kitna pani, and the one in midlee would keep saying itna pani etc..she would indicate with her hands, starting from legs, saying itna pani and then move her hands up,,,moving from legs to the stomach and like. and finally when she is submerged, basically when she moves her hands to her head, the other girls would run and she has to catch someone !!
