When it comes to action, none are better than the real-time battle arena in Clash Royale. It's designed around the record-breaking Clash of Clans universe, where players get to collect cards and use them as a battle deck. It's a top-down realtime strategy game that is extremely addicting, yet frustrating at the same time.
It was one of the highest grossing mobile games in history and all of 2016, and it's only been available for about a year. Supercell updates it with more features, troops and cards almost every month to keep things fresh too. Not to mention balance changes so the game and your skills are always evolving as you play.
Clash Royale is one of the most popular mobile games on the planet right now for a reason. It's fun. We will warn you though, it's addicting, and really easy to start spending a lot of money on in-app purchases to upgrade your troops and win more battles. Keep that in mind, and download it today.
