Your small investments upto 1500/- is not much of a problem. Paisa withdraw bhi ho jata hai. Then suddenly you will get a jackpot of 20000/- and 3 orders you r mandatorily required to place. In the first two orders only your 20000/- will be exhausted and the game expects you to put another 10-12 thousand from pocket. This where u get stuck since the first two orders get locked. You are required to complete the 3rd order, only after which that bastard says u can withdraw money in full.
