Hey folks this is not anything new,that earning points by playing games will reward you, whats new is who is providing..
Microsoft to promote its Live search has come up with a Live Club, where you will get tickets (Points) for playing games and on other section you will get tickets to search on live..
I am not sure how will they reward and when, but I liked few games and am playing them atleast for fun! :)
If you want more info, visit homepage..

UPDATE : This is not for us Indian's, sorry missed to see the important T&C!
