It took me 55 days, but I finally have the Prince. But after getting lucky and patiently biding my time, I was finally able to secure the slippery card. The title from Helsinki-based Supercell is No. On a worldwide basis, Clash Royale was the No. Supercell also has the No. In Clash Royale, two human players battle each other in real time. There are two paths to the enemy. You have a set of four cards to choose from at any one time. If you have enough points, you can play a card. The points are regenerated at an even rate for both sides. It takes some time for each card to play out, and so timing and card selection are key. If you play the right card, you can overwhelm the enemy and push toward a castle and then destroy it.
