In the beginning, this game was awesome! Towards the middle, I started getting slightly bored, but I kept going. I was getting close to my reward, and I started getting 0.01 diamonds a round. To get from 9,999 to 10,000, getting only 0.01 a round, is highly annoying! 1 star is being kind. I would not suggest wasting your time on this game. 😒 VERY disappointed! One other thing, when you watch an ad, the math calculations are wrong! Again, HIGHLY disappointed in this game. Needs to be changed.
