The ad system of this game is just horrible and bad. Game officials keep asking players to help them watch ads, but the ads they play are all. . . The ads they play either have no graphics at all and the game will freeze, or we won't be rewarded at all after the viewing is over. And the ad supply is not enough, I only watched a few ads and they told me that there were no more ads to watch. I don't get the reward at all, instead they keep making money.
