Bulb smash is the worst app to earn paytm money it only waste your time. I have downloaded it to earn some paytm money and played it some days but after some days.i have completed all the levels and then they say that wait for the next level to come I have also tried to participate in the competition but u can never win it. If u want to win just give money to buy powerups or booster. It is a app which waste your time only nothing else. Don’t ever download it.
