Clash Royale gets you the same characters as Clash of Clans into a card and turn-based rumble.
Grab and collect all the cards. Don't worry, you'll eventually have your deck memorized and start making adjustments to it in your sleep.
All of the important characters from Clash of Clans are there: Giants, Knights, Princes, Witches.... and with them all you'll develop your own style of game. More magic? Power or speed? It's up to you.
You can join or create your own clan and gather your friends around a common goal: VICTORY!
