I was able to make exactly one move on the board before a noisy full-screen advertisement (with a mute button but no dismiss button) took over. Waiting for the ad to finish led into one of those extremely aggravating ‘try a demo of this advertised game’ ads, still no dismiss button and no way to get back to the game itself.
What’s the point of a game you can’t play? I’m not wasting app install space just to watch ads.
