If it were possible to give negative stars, I would. Sooooooo, I get the idea of ads at the beginning or end of gameplay..it's expected in a "free" game... but in the middle of playing you are stopped and directed to watch ads or lose your turn and be defeated... that's really stupid and frustrating... which means no one is actually watching the ads... at all, ever... I'd rather pay for the game, once and done, than have my time wasted with unimaginative, banal, and completely worthless ads.
