What's your favorite mobile game?

Maybe when it's a little more convenient for me, I'll give Clash Royale a run for my money and see how much I get to enjoy it.
There's no need to pay to enjoy Clash Royale. Sure, you can speed up your levelling but it's not necessary. You just have to learn the strategies, what cards to use, how to counter them, etc. It's not a pay-to-win game.

I know that it's not a pay to win game. I will definitely look for good strategies to build on with when playing the game as soon as I can get into it.
