Played this game for years, it used to be the best app to kill time, with the new updates, it is obviously clear that you won't finish challenges or progress without spending money, plus the sudden crashes which leads yo loosing the challenge, contacted support and they were not even bothered, unfortunately uninstaled it Reply: Too late, I raised this issue long time and the contact person was rude, I tried to explain that I have wasted lots of money and effort but he/she showed no interest
