Clash Royale is a free mobile video game released on January 4, 2016. It is certainly a game where battles really unfold as reality. My letter as you can see below, I recommend it. Sincerely, it's a game where you have to bet everything.
Since it is a relatively new game, they are updating them better and better, with battles in pairs and up to four people simultaneously. It's even a family game.
Your letters (characters), have even your own stories, look for it.
