I have used it in 2014-2015 but only earned 40-50₹ and needs a lot of time. We have to complete tasks only will give 0.5 paisa or 0.15.
I will not recommend you to play it if you are a school student because it wastes your time and distractes you to play other games. instead of this you can play games.
I have not recommended because it wastes time of 30 min for just only 0.15 paisa
