This is terrible. Ive been playing for more than a week and i can't even get the first reward. At first it was giving like 200+ gems but after the first 3 games it started giving me 56- and after like 6 more games it started givin 7 to 8 gems. This game is a waste of time and i wouldn't recommend it. If u have a ton of time to waste though, just put ur earphones and prepare for not only 1 ad every game but 2 ads every 2 seconds. ofcourse i uninstalled it but i bet if i still played it'd give 1.
