Clash royale is developed by supercell and is very addictive game. Its out of the box thinking to use portrait screen instead of landscape. This makes gameplay userfriendly. The frequent updates to the game keep your interest increasing.
In this game, you basically have a deck of 8 cards. When you deploy any of the cards, it acts as a defence unit by your side. 3very card costs certain elixir which increases along with the time in equal intervals. You have to destroy opponents towers to win.
This simplicity of the game attracts many users who just want to play game to relieve stress or feel calm. They dont tend to play complex games and this is the best choice.
I would recommend this game for such people cause I am one of them too.
