This strategy game from Supercell comes with beautiful graphics, although they’re a bit cartoonish for many players of this type of game. Unlike the company’s other big hit, this is a real-time multiplayer game that allows you to collect and upgrade cards featuring troops, spells and defenses, from the Clash of Clans game. You’ll duel players in real-time, take their trophies when you win, unlock rewards, and more. It’s a rather nice game to play and you can at least try it out if nothing else, since it’s free to play. In-app purchases are, of course, available.
