" NOT ABLE GENRATE COIN WITHOUT WATCHING ADVERTIMENT" I would like to give 5 star but Strucher to earn coins are very difficult. One can not generate coins without watching add evertime. U GUYS OFFER 3 × MORE COINS IF SOME ONE WATCH ADVERTISEMENT. ON OTHER HAND UPGRADE IS SO COSTLY. ONE CAN NOT ABLE EARN ENOUGH COIN WITHOUT WATCHING ADD. PLZ LOOK INTO THIS.ITS FEEL LIKE LESS TIME IN GAME MORR ON ADVERTISING.
