The game is nice, but progression is almost impossible if you don't spend money. This game is here to suck your wallet. Make no mistake. There are nice elements, but all would require money. There's a fixed limited in-game premium cash (diamond/gem) that they give you for completing a section of the game, but make no mistake, you WILL NOT complete the game if you don't spend. Go to "Game of Warriors" if you want completion. Play this if you just want fun.
