I'm playing via Google Play Games Beta on PC. Every once in a while I will get stuck by an advertisement that I can't completely see (it only shows one corner of the ad screen). There is no way for me to exit these ads so I can't continue playing and must exit the game. I've just had to exit the game three times without ever being able to play. I enjoy the game but can't rate more stars due to the ads making it impossible to play.

Would get 5 stars, but always populates a new "adventure" when you're almost done the one you're on, and when you select "no thank you" it still replaced your existing mission with the new one you don't want to play. Don't give the option if therev really ISN'T one. That being said, very addicting game. There are times you think you're at a dead end but the RNG gives you pieces that will work IF they are placed JUST RIGHT. Great strategy!

2 reasons for a 2 star instead of 5.. first one is THE ADS... my god, soooo many ads!! I get it's a free game so they have to get the money somewhere but come on! you have to watch an ad just to launch the game!! like really, at least let me get one round in before I have to watch an ad. yes for $4 you can get ad free.. dont screw up and delete the game like I did, had a similar one that I didn't like as much and accidentally deleted this one, reinstalled it aaandd, it didn't save any progress!!
