What is Scrolls?
Scrolls is a fresh take on the collectible card games of old. It’s developed by Mojang – creators of Minecraft. You’ll create your own personalised army from a digital deck before unleashing it in battles with players around the world. It will eventually be released on PC, Mac, Android and iOS.
