5 stars: An absolute banger of a game. been playing for almost 4 years and it never disappointed me, the only cons are that pay 2 win is very popular in this game but it's completely optional, and watching tons of ads and completing surveys seems like your only option to avoid it but it's also completely optional, if you play seriously enough you'll get some of the best monsters out there.
5 stars: It's mostly fun I enjoy it just wish gems were little easier to get but I understand why they are hard to get and also the building time is way too long other than that it's actually good graphics and moves animations and grinding on the game is fun actually not boreing and the monsters are Sick (awesome)
4 stars: It's a good game, the visuals are very polished, the sounds are great. There are nice little animations when you unlock/achieve something. But it is definitely pay to win, and they are not afraid to ask you to spend. Every non-basic item required
