Flashing ads on screen very distracting

I really enjoy this game but it gives me a headache to try to tune out the flashing ads at the bottom of the screen. Ive tried to place something over the screen bottom but always inadvertently touch the screen and the advertisers screen takes over. Why isnt there a purchased version of this game to avoid the ads? What a shame a really good game is ruined by the greed of the developers.
