Tried this for gems and it was so tedious. It's full of ads. It shows an ad after EVERY game regardless of whether you win or lose the level. The ads are often obnoxious and hard to tap out of. You get very little despite watching hundreds of ads and one game costs 3500 coins to play, and you get 500 to watch an ad... And if you win the level you're lucky to break even. You can maximize your money by, yep, watching more ads. Feels greedy. There are better Solitaire games out there.
