I have played on Qureka online earning application for a certain period of two weeks and I found that it is a scam.In Qureka you can earn through answering quizzes and playing mini-games in a head to head contest or a mega contest where the prize amount is distributed among winners.But winning here is very very rare and the winning amount will be a less one.It would take you about months to earn a little amount of money and the withdrawl function in this application is not working properly in which you will receive an error message when you click withdrawl.Don’t waste your time in playing this app.
