The game itself is fun. It's a time waster game to relax. The one start is because you have watch constantly watch ads to purges they the game. Rather than offer to pay for ad-free, the offer is $7.50 for 120 ad-free moves. I pay because I like to support the game developers however the game kept crashing and taking me back to the beginning. It happened about 4 times, the last when I was very advanced into the game. I own the game and I'm back at the very start of the game. Super frustrating.
