Adiction to Clash Royale

Clash Royale is a game derived from the Clash Of Clans which is a game that consists to realize battles against other players online. This game consists of obtaining and improving cards that you have to go obtaining with your progress in the game. It is a very addictive game because it creates competitiveness and rivality. 
This does that the players pass many hours of his free time in something that only is going to give headaches to them. I personally have played to this game and I had a season where I was really stuck in this game, but luckily I have changed my mobile and with this i arrived to the conclusion of not installing the game again. I think that those type of game's only increase the levels of violence of the people that use them
