It'll come to an end when they try to force you to buy fake coins for real money.
Once you make a purchase, you will win a couple of times. This game is coded to give you small wins here and there, and then to try and push you into making a purchase once they make you lose it all. I have been doing an experiment for 4 years to prove their use of a rigged algorithm, and my hypothesis has been proven across 7 different accounts.
This game is completely rigged and they even have a class action lawsuit against them.
