I like the game. Honestly, I would give this game a 4 or even 5 star review if it wasn't for one thing: the gem system. Sure, they give you the option to buy some gems, but it is more money than i can spend on a game. The only other option is to watch an ad for 2 gems. The problem with that is you can only watch one ad a day. In order to get most of the avatars and dice, it would take me an entire year of watching one ad a day. It would be better if we could watch more than one ad a day.
