New rating due to advertising. Not because there are ads but because of a high frequency of the game refusing to give the reward. The ads that run 20-30 seconds & put arrows in the upper corner that lead to another 5-15 second ad & sometimes a 3rd segment for 5-10 seconds & finally you get an x to close them...the game always denies the award claiming you closed the ad. You watch the longest ads, they get their revenue & give u nothing. It isn't uncommon to get 3, 4 or 5 of these ads in a row.
