Guys if you look to the right of the game window and press the achievements tab then press All-time and make sure the mode is on "coins", a guy called Marcoagr has 2,000,000,000,000,000 coins. I think he should be banned..
@Verasis it usually takes at least an hour and a half or more for the rest to run out, and in that time you can make enough money to "buy" more with money in-game. and besides, it's not healthy to play for that much each day anyways.
@cat1432 It's funny that you think this game is hard because all you ever do is click.... this has got to be one of the easiest games ever; what you mean is that it's TIME CONSUMING. If you want a hard game, I invite you to go play StarCraft 2 and see if you can get into the Grandmaster league -.-
For those complaining about gems; it's completely fair. I myself have never paid and yet I do surveys and have gotten around 150 kreds to use on gems. If you want something bad enough... you'll always eventually get it.
