Fantastic. It meets the Supercell level of competitive, high-skill cap gameplay, while being extremely simple to understand. I've played since launch, and I've never had any issues with the game until recently, when the new eSports prediction challenge wasn't working for me and a good handful of other players. As an apology, they gave me all of the rewards I missed out on. Truly great customer support. If you're looking for a game to sink hours into with or without your friends, here it is.
