Greedy dev, there is no real randomness when the card are given. Often there is pattern that's repeats itself the way the card are given to the players. I believe this game is rigged. I did play a lot. It's just been designed to spend money. Doesn't matter if you use multiplier or not They barely give you access to the ads to get free coins. It's very fun game but a money trap. I'll guess I'll found an other game.
