Finally i found the Led small ball (कंचा) in a glossary store and i became happy after looking those because i had played a lot with these balls with childhood friends. You can see those here and can recall the childhood memories if you had played with these. Just after school schedule we gathered in a plain surface.
I have searched in google and found some pictures of children playing with it.
As you can see on above image a boy is targeting to stumble to other small balls using his finger and if his ball touches the fixed target then he becomes winner. In above image boy and led balls are very close but in real target balls are far at least 2 to 3 meter. It is not easy to target other ball using any hand finger hence it was tough game too. As a winner we used to win others led ball.
