Good early bad later

So the game I feel is designed very well EXCEPT the ad banner at the bottom of the screen. Its fine for the first 10 or so puzzles but after that the ad banner starts to block rows of the puzzles to where you cant even see the hints for that row making anything bigger than 11xX impossible to play. So unless you pay to remove the ad banner you get stuck by poor ad placement.
